ELECTRONIC DEVICE FOR CONTROLLING ANTENNA SETTING AND OPERATING METHOD THEREOF

BACKGROUND
Field

The disclosure relates to an electronic device for controlling antenna setting and an operating method thereof.

Description of Related Art

Recently, as the use of portable terminals providing various functions has become common according to the development of mobile communication technology, efforts have been made to develop a 5^thgeneration (5G) communication system to meet the growing demand for wireless data traffic. The 5G communication system has been considered to be implemented in a higher frequency band (e.g., a band of 25 to 60 GHz) in addition to frequency bands used in a 3^rdgeneration (3G) communication system and a long term evolution (LTE) communication system in order to provide a higher data transmission speed for achieving a high data rate.

For example, in order to mitigate path loss of radio waves and increase a propagation distance of the radio waves in a millimeter wave (mmWave) band, a beamforming technology, a massive multiple-input multiple-output (MIMO) technology, a full dimensional MIMO (FD-MIMO) technology, an array antenna technology, an analog beamforming technology, and a large scale antenna technology have been discussed for use in the 5G communication system.

An electronic device is simplified for efficient use of a system, and an antenna is also required to be simplified while satisfying a high gain characteristic. The electronic device generates an electromagnetic wave, and transmission power of the antenna may be increased to improve a transmission performance of the antenna. A numerical value representing a degree to which the generated electromagnetic wave is absorbed by the human body is a specific absorption rate (SAR), and transmission power of the electronic device may be limited in order to satisfy regulatory standards for SAR.

The electronic device may include a grip sensor, and the grip sensor may be used to sense a change in an electric charge of a metal part of the antenna, and may recognize an approach of or a proximity of a dielectric such as the human body. If the grip sensor recognizes the approach of or the proximity of the human body, transmission power of a signal transmitted from the electronic device may be maintained at a level which may satisfy the regulatory standards for SAR.

In order for the electronic device to transmit a signal to a communication network (e.g., a base station), data generated from a processor or a communication processor within the electronic device may be transmitted via at least one antenna after being processed through a radio frequency integrated circuit (RFIC), a radio frequency front end (RFFE), and an antenna tuning circuit.

If a dielectric approaches or is in proximity with at least one antenna, impedance of the at least one antenna may change, and a radio frequency (RF) performance may be degraded due to this. The electronic device uses an antenna tuning circuit to improve an RF performance in various scenarios. In this case, the electronic device may recognize the approach of or proximity of the dielectric to the antenna via the grip sensor, and operate the antenna tuning circuit to mitigate degradation in an RF performance due to the approach of or proximity of the dielectric.

The grip sensor consumes current when turned on, so the electronic device may turn on or turn off the grip sensor according to a state (e.g., a radio resource control (RRC) idle (RRC_IDLE) state, an RRC inactive (RRC_INACTIVE) state, or an RRC connected (RRC_CONNECTED) state) of the electronic device. To prevent current consumption due to turn-on of the grip sensor, the electronic device may turn off the grip sensor if the state of the electronic device is the RRC_IDLE state or the RRC_INACTIVE state, and may turn on the grip sensor if the state of the electronic device is the RRC_CONNECTED state.

As such, if the state of the electronic device is the RRC_IDLE state or the RRC_INACTIVE state, the grip sensor may be turned off. Therefore, the electronic device may not operate the antenna tuning circuit due to the approach of or proximity of the dielectric sensed by the grip sensor, and this may cause performance degradation in a reception operation of the electronic device, such as an operation of receiving a paging signal, and performance degradation in a transmission operation of the electronic device, such as a case in which the electronic device performs a random access procedure in the RRC_IDLE state.

The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

FIG. 2A is a block diagram 200 illustrating an example electronic device 101 for supporting a legacy network communication and a 5^thgeneration (5G) network communication according to various embodiments.

Referring to FIG. 2A, an electronic device 101 (e.g., an electronic device 101 in FIG. 1) may include a first communication processor 212, a second communication processor 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front end (RFFE) 232, a second RFFE 234, a first antenna module 242, a second antenna module 244, a third antenna module 246, and antennas 248. The electronic device 101 may further include a processor 120 and a memory 130. A second network 199 may include a first cellular network 292 and a second cellular network 294. According to an embodiment, the electronic device 101 may further include at least one of the components illustrated in FIG. 1, and the second network 199 may further include at least one other network. According to an embodiment, the first communication processor 212, the second communication processor 214, the first RFIC 222, the second RFIC 224, the fourth RFIC 228, the first RFFE 232, and the second RFFE 234 may form at least part of a wireless communication module 192. According to an embodiment, the fourth RFIC 228 may be omitted or included as part of the third RFIC 226.

The first communication processor 212 may establish a communication channel in a band to be used for a wireless communication with the first cellular network 292 and support a legacy network communication via the established communication channel. According to an embodiment, the first cellular network 292 may be a legacy network including a 2^ndgeneration (2G) network, a 3^rdgeneration (3G) network, a 4^thgeneration (4G) network, or a long term evolution (LTE) network. The second communication processor 214 may establish a communication channel corresponding to a specified band (e.g., about 6 GHz to about 60 GHz) out of a band to be used for a wireless communication with the second cellular network 294 and support a 5G network communication via the established communication channel According to an embodiment, the second cellular network 294 may be a 5G network defined by the 3^rdgeneration partnership project (3GPP). Additionally, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another specified band (e.g., about 6 GHz or less) out of the band to be used for the wireless communication with the second cellular network 294 and support a 5G network communication via the established communication channel.

The first communication processor 212 may transmit and receive data to and from the second communication processor 214. For example, data supposed to be transmitted via the second cellular network 294 may be scheduled to be transmitted via the first cellular network 292. In this case, the first communication processor 212 may receive transmission data from the second communication processor 214. For example, the first communication processor 212 may transmit and receive data to and from the second communication processor 214 via an inter-processor interface 213. The inter-processor interface 213 may be implemented as, for example, a universal asynchronous receiver/transmitter (UART) (e.g., high speed-UART (HS-UART)) or a peripheral component interconnect bus express (PCIe) interface, but a type thereof is not limited. Alternatively, the first communication processor 212 and the second communication processor 214 may exchange control information and packet data information using, for example, a shared memory. The first communication processor 212 may transmit and receive various pieces of information such as sensing information, information about output strength, and resource block (RB) allocation information to and from the second communication processor 214.

According to an embodiment, the first communication processor 212 may not be coupled directly to the second communication processor 214. In this case, the first communication processor 212 may transmit and receive data to and from the second communication processor 214 via the processor 120 (e.g., an application processor). For example, the first communication processor 212 and the second communication processor 214 may transmit and receive data to and from the processor 120 via an HS-UART interface or a PCIe interface, but a type of an interface is not limited. Alternatively, the first communication processor 212 and the second communication processor 214 may exchange control information and packet data information using, for example, the processor 120 and the shared memory.

According to an embodiment, the first communication processor 212 and the second communication processor 214 may be incorporated in a single chip or a single package. According to an embodiment, the first communication processor 212 or the second communication processor 214 may be incorporated together with the processor 120, an auxiliary processor 123, or a communication module 190 in a single chip or a single package. For example, as illustrated in FIG. 2B, an integrated communication processor 260 may support all of a function for a communication with the first cellular network 292 and a function for a communication with the second cellular network 294.

For transmission, the first RFIC 222 may convert a baseband signal generated by the first communication processor 212 to a radio frequency (RF) signal in about 700 MHz to about 3 GHz used in the first cellular network 292 (e.g., the legacy network). For reception, an RF signal may be obtained from the first cellular network 292 via an antenna (e.g., the first antenna module 242) and pre-processed via an RFFE, (e.g., the first RFFE 232). The first RFIC 222 may convert the pre-processed RF signal to a baseband signal so that the baseband signal may be processed by the first communication processor 212.

For transmission, the second RFIC 224 may convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 to an RF signal in a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network 294 (e.g., the 5G network). For reception, a 5G Sub6 RF signal may be obtained from the second cellular network 294 via an antenna (e.g., the second antenna module 244) and pre-processed in an RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the pre-processed 5G Sub6 RF signal to a baseband signal so that the baseband signal may be processed by a corresponding one between the first communication processor 212 and the second communication processor 214.

For transmission, the third RFIC 226 may convert a baseband signal generated by the second communication processor 214 to an RF signal (hereinafter, referred to as, a 5G Above6 RF signal) in a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) used in the second cellular network 294. For reception, a 5G Above6 RF signal may be obtained from the second cellular network 294 via an antenna (e.g., the antenna 248) and pre-processed via the third RFFE 236. The third RFIC 226 may convert the pre-processed 5G Above6 RF signal to a baseband signal so that the baseband signal may be processed by the second communication processor 214. According to an embodiment, the third RI-PE 236 may be formed as part of the third RFIC 226.

According to an embodiment, the electronic device 101 may include the fourth RFIC 228 separately from or as part of the third RFIC 226. In this case, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 to an RF signal in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) (hereinafter, referred to as an intermediate frequency (IF) signal), and provide the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal to a 5G Above6 RF signal. During reception, a 5G Above6 RF signal may be received from the second cellular network 294 through an antenna (e.g., the antenna 248) and converted to an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal to a baseband signal so that the baseband signal may be processed by the second communication processor 214.

According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least part of a single chip or a single package. According to an embodiment, if the first RFIC 222 and the second RFIC 224 are implemented as a single chip or a single package in FIG. 2A or 2B, the first RFIC 222 and the second RFIC 224 may be implemented as an integrated RFIC. In this case, the integrated RFIC is connected to the first RI-PE 232 and the second RFFE 234, so the integrated RFIC may convert a baseband signal into a signal of a band supported by the first RFFE 232 and/or the second RFFE 234, and transfer the converted signal to one of the first RFI-E, 232 and the second RFFE 234. According to an embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as at least part of a single chip or a single package. According to an embodiment, at least one of the first antenna module 242 or the second antenna module 244 may be omitted or combined with the other antenna module to process RF signals in a plurality of corresponding bands.

According to an embodiment, the third RFIC 226 and the antenna 248 may be arranged on the same substrate to form a third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be arranged on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 may be arranged in a partial area (e.g., the bottom surface) of a second substrate (e.g., a sub PCB) other than the first substrate and the antenna 248 may be arranged in another partial area (e.g., the top surface) of the second substrate, to form the third antenna module 246. As the third RFIC 226 and the antenna 248 are arranged on the same substrate, it is possible to reduce length of a transmission line between the third RFIC 226 and the antenna 248. This may reduce, for example, loss (e.g., attenuation) of a signal in a high frequency band (e.g., about 6 GHz to about 60 GHz) used for a 5G network communication, on the transmission line. Therefore, the electronic device 101 may increase quality or a speed of a communication with the second cellular network 294 (e.g., the 5G network).

According to an embodiment, the antenna 248 may be formed as an antenna array including a plurality of antenna elements which may be used for beamforming. In this case, for example, the third RFIC 226 may include a plurality of phase shifters 238 corresponding to the plurality of antenna elements, as part of the third RFFE 236. During transmission, each of the plurality of phase shifters 238 may change a phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device 101 (e.g., a base station in the 5G network) via a corresponding antenna element. During reception, each of the phase shifters 238 may change a phase of a 5G Above6 RF signal received from the outside via a corresponding antenna element to the same or substantially same phase. This enables transmission or reception via beamforming between the electronic device 101 and the outside.

The second cellular network 294 may be operated independently of the first cellular network 292 (e.g., stand-alone (SA)) or in connection to the first cellular network 292 (e.g., non-stand alone (NSA)). For example, in the 5G network, only an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) may exist, and a core network (e.g., a next generation core (NGC)) may not exist. In this case, after accessing the access network of the 5G network, the electronic device 101 may access an external network (e.g., an Internet) under the control of a core network (e.g., an evolved packet core (EPC)) of the legacy network. Protocol information for a communication with the legacy network (e.g., LTE protocol information) and protocol information for a communication with the 5G network (e.g., new radio (NR) protocol information) may be stored in the memory 230 and accessed by another component (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

FIG. 2B is a block diagram 250 illustrating an example electronic device for supporting a legacy network communication and a 5G network communication according to various embodiments.

The electronic device 101 may further include a processor 120 and a memory 130. A second network 199 may include a first cellular network 292 and a second cellular network 294.

In the block diagram 250 of the electronic device 101 shown in FIG. 2B comparing to the block diagram 200 of the electronic device 101 shown in FIG. 2A, it differs in that the first communication processor 212 and the second communication processor 214 are implemented as the integrated communication processor 260, and the remaining components included in the block diagram 250 of the electronic device 101 may be implemented similarly or substantially the same as the components included in the block diagram 200 of the electronic device 101 shown in FIG. 2A, so a detailed description thereof will not be repeated.

As described above, DC through the LTE base station 340 and the NR base station 350 may be referred to as E-UTRA new radio dual connectivity (EN-DC).

FIG. 4 is a block diagram illustrating an example electronic device according to various embodiments.

Referring to FIG. 4, an electronic device 101 (e.g., an electronic device 101 in FIGS. 1, 2A, 2B, and 3A to 3C) may include an application processor 120 (e.g., a processor 120 in FIG. 1, 2A, or 2B), a communication processor 260 (e.g., a processor 120 in FIG. 1, a first communication processor 212 or a second communication processor 214 in FIG. 2A, or an integrated communication processor 260 in FIG. 2B), a grip sensor 410 (e.g., a sensor module 176 in FIG. 1), an RFIC 420 (e.g., a first RFIC 222, a second RFIC 224, a third RFIC 226, or a fourth RFIC 228 in FIG. 2A, or a first RFIC 222, a second RFIC 224, a third RFIC 226, or a fourth RFIC 228 in FIG. 2B), an RFFE 430 (e.g., a first RFFE 232, a second RFFE 234, and a third RFFE 236 in FIG. 2A, or a first RFI-E, 232, a second RFFE 234, and a third RFFE 236 in FIG. 2B), an antenna tuning circuit 440, and an antenna 460. In an embodiment, an RF circuit 450 may include an RFIC 420 and an RFFE 430. In FIG. 4, a case in which the electronic device 101 includes one antenna (e.g., the antenna 460) will be described as an example, but the electronic device 101 may include one or more antennas.

According to an embodiment, the grip sensor 410 may recognize approach of or proximity of a dielectric such as a human body. The grip sensor 410 may perform a sensing operation and transfer grip sensor status (grip status) information indicating a sensing result to the application processor 120. The grip sensor status information may indicate “grip touch status” indicating grip status or “grip release status” indicating free space status.

The application processor 120 may receive grip sensor status information from the grip sensor 410, and generate grip status information based on the received grip sensor status information. The grip status information may indicate a “grip touch status” or a “grip release status”. The application processor 120 may transfer the generated grip status information to the communication processor 260.

The communication processor 260 may control an operation of the RF circuit 450. In an embodiment, the communication processor 260 may control a setting value (e.g., a tuning value) of the antenna tuning circuit 440, and the antenna tuning circuit 440 may perform an antenna tuning operation based on a setting value set by the communication processor 260.

According to an embodiment, in a grip status due to approach of or proximity of a dielectric, antenna efficiency per frequency of the electronic device 101 may change, so antenna efficiency at a target frequency may also change. A change in the antenna efficiency per frequency due to the approach of or proximity of the dielectric is a characteristic of the electronic device 101, so the communication processor 260 may identify the change in the antenna efficiency per frequency due to the approach of or proximity of the dielectric in advance. For example, the communication processor 260 may identify the change in the antenna efficiency per frequency due to the approach of or proximity of the dielectric in a laboratory environment in advance. So, the communication processor 260 may store a setting value to be used by the antenna tuning circuit 440 in grip status and a setting value to be used by the antenna tuning circuit 440 in free space status in advance, based on the change in the antenna efficiency per frequency due to the approach of or proximity of the dielectric. In an embodiment, the communication processor 260 may store setting values to be used by the antenna tuning circuit 440 in advance in a form of a table including a setting value to be used by the antenna tuning circuit 440 in grip status and a setting value to be used by the antenna tuning circuit 440 in free space status per frequency.

According to an embodiment, when transiting to a radio resource control (RRC) idle (RRC_IDLE) state or an RRC inactive (RRC_INACTIVE) state, the communication processor 260 may turn off the grip sensor 410. According to an embodiment, when transiting to an RRC connected (RRC_CONNECTED) state, the communication processor 260 may turn on the grip sensor 410. The communication processor 260 may control (or set) a setting value of the antenna tuning circuit 440 based on an RRC state.

Referring to FIG. 5, an antenna tuning circuit 440 (e.g., an antenna tuning circuit 440 in FIG. 4) may include at least one impedance tuning circuit 510 and/or at least one aperture tuning circuit 520.

The impedance tuning circuit 510 may be configured to perform impedance matching with a network under the control of at least one communication processor (e.g., a processor 120 in FIG. 1, a first communication processor 212 or a second communication processor 214 in FIG. 2A, or an integrated communication processor 260 in FIG. 2B).

The aperture tuning circuit may change a structure of an antenna (e.g., an antenna 460 in FIG. 4) by turning on/off a switch under the control of the at least one communication processor.

According to an example embodiment of the disclosure, an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) may include at least one sensor (e.g., a sensor module 176 in FIG. 1) including a grip sensor (e.g., a grip sensor 410 in FIG. 4), at least one antenna (e.g., an antenna 460), a radio frequency (RF) circuit (e.g., an RF circuit 450 in FIG. 4) including at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4) connected to the at least one antenna (e.g., the antenna 460), and at least one communication processor (e.g., a processor 120 in FIG. 1, a first communication processor 212 or a second communication processor 214 in FIG. 2A, or an integrated communication processor 260 in FIG. 2B or 4) operatively connected to the RF circuit.

According to an example embodiment of the disclosure, the at least one communication processor (e.g., the processor 120 in FIG. 1, the first communication processor 212 or the second communication processor 214 in FIG. 2A, or the integrated communication processor 260 in FIG. 2B or 4) may be configured to: transit to a radio resource control (RRC) idle (RRC_IDLE) state or an RRC inactive (RRC_INACTIVE) state, and maintain a first tuning value which is a tuning value of the at least one antenna tuning circuit (e.g., the antenna tuning circuit 440 in FIG. 4) which corresponds to the grip sensor (e.g., the grip sensor 410 in FIG. 4) before transition to the RRC_IDLE state or the RRC_INACTIVE.

According to an example embodiment of the disclosure, the at least one communication processor (e.g., the processor 120 in FIG. 1, the first communication processor 212 or the second communication processor 214 in FIG. 2A, or the integrated communication processor 260 in FIG. 2B or 4) may be further configured to identify whether a random access response (RAR) signal is received via the RF circuit (e.g., the RF circuit 450 in FIG. 4) in response to the random access preamble signal.

According to an example embodiment of the disclosure, the at least one communication processor (e.g., the processor 120 in FIG. 1, the first communication processor 212 or the second communication processor 214 in FIG. 2A, or the integrated communication processor 260 in FIG. 2B or 4) may be further configured to control the RF circuit (e.g., the RF circuit 450 in FIG. 4) to transmit the random access preamble signal based on the first transmission power and the second tuning value.

According to an example embodiment of the disclosure, the set condition may include a condition that the first transmission power is equal to threshold transmission power.

According to an example embodiment of the disclosure, the threshold transmission power may include maximum transmission power (Max Tx power) usable for transmitting the random access preamble signal.

According to an example embodiment of the disclosure, the at least one communication processor is configured to: control the RF circuit to transmit the random access preamble signal a set number of times until the RAR signal is received.

According to an example embodiment of the disclosure, the second tuning value may correspond to a second status different from a first status of the grip sensor which corresponds to the first tuning value.

According to an example embodiment of the disclosure, the first status of the grip sensor (e.g., the grip sensor 410 in FIG. 4) may include one of grip touch or grip release.

According to an example embodiment of the disclosure, the at least one communication processor (e.g., the processor 120 in FIG. 1, the first communication processor 212 or the second communication processor 214 in FIG. 2A, or the integrated communication processor 260 in FIG. 2B or 4) may be further configured to identify whether a random access response (RAR) signal is received via the RF circuit (e.g., the RF circuit 450 in FIG. 4) in response to the random access preamble signal.

According to an example embodiment of the disclosure, the at least one communication processor (e.g., the processor 120 in FIG. 1, the first communication processor 212 or the second communication processor 214 in FIG. 2A, or the integrated communication processor 260 in FIG. 2B or 4) may be further configured to change a tuning value of the at least one antenna tuning circuit (e.g., the antenna tuning circuit 440 in FIG. 4) which corresponds to the grip sensor (e.g., the grip sensor 410 in FIG. 4) from the first tuning value to a second tuning value, based on the set condition being satisfied.

According to an example embodiment of the disclosure, the at least one communication processor (e.g., the processor 120 in FIG. 1, the first communication processor 212 or the second communication processor 214 in FIG. 2A, or the integrated communication processor 260 in FIG. 2B or 4) may be further configured to control the RF circuit (e.g., the RF circuit 450 in FIG. 4) to transmit the random access preamble signal based on the first transmission power and the second tuning value.

According to an example embodiment of the disclosure, the set condition may include a condition that the first transmission power is equal to threshold transmission power.

FIG. 6 is a flowchart illustrating an example operating method of an example electronic device according to various embodiments.

Referring to FIG. 6, an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) (e.g., a processor 120 in FIG. 1, a first communication processor 212 or a second communication processor 214 in FIG. 2A, or an integrated communication processor 260 in FIG. 2B or 4) may transit to an RRC_IDLE state or an RRC_INACTIVE state in operation 611. In an embodiment, when transiting to the RRC_IDLE state or the RRC_INACTIVE state, the electronic device may turn off a grip sensor (e.g., a grip sensor 410 in FIG. 4).

After transiting to the RRC_IDLE state or the RRC_INACTIVE state, the electronic device may, in operation 613, maintain a first setting value which is a setting value of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4 or 5) which corresponds to a grip sensor (e.g., a grip sensor 410 in FIG. 4) before transition to the RRC_IDLE state or the RRC_INACTIVE state. If grip status information before transition to the RRC_IDLE state or the RRC_INACTIVE state indicates grip touch status, the first setting value may be a setting value used by the at least one antenna tuning circuit in grip status for a frequency used in an RF circuit (e.g., an RF circuit 450 in FIG. 5) including the at least one antenna tuning circuit connected to at least one antenna (e.g., an antenna 460 in FIG. 4). If the grip status information before transition to the RRC_IDLE state or the RRC_INACTIVE state indicates grip release status, the first setting value may be a setting value used by the at least one antenna tuning circuit in free space status for the frequency used in the RF circuit.

In operation 615, the electronic device may transmit a first signal for a random access to a base station based on first transmission power and the first setting value. In an embodiment, the electronic device may control the RF circuit to transmit the first signal for the random access based on the first transmission power and the first setting value. In an embodiment, the first signal may include a random access preamble signal. In an embodiment, the first signal may include the random access preamble signal and data by first scheduled transmission in a random access procedure. In an embodiment, if the electronic device performs a 4-step random access procedure, the first signal may include the random access preamble signal. In an embodiment, if the electronic device performs a 2-step random access procedure, the first signal may include the random access preamble signal and the data by the first scheduled transmission. In an embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number of times indicated by a parameter preambleTransMax) until a second signal is received. In an embodiment, the parameter preambleTransMax may indicate a maximum number of times for transmission of the first signal performed before failure of the random access procedure is declared. So, operation 615 may be performed only until the maximum number of times for transmission of the first signal is reached. In an embodiment, the second signal may be a response signal to the first signal. In an embodiment, the second signal may include a random access response (RAR) signal. In an embodiment, the second signal may include the RAR signal and contention resolution. In an embodiment, if the electronic device performs the 4-step random access procedure, the second signal may include the RAR signal. In an embodiment, if the electronic device performs the 2-step random access procedure, the second signal may include the RAR signal and the contention resolution.

In operation 617, the electronic device may identify whether the second signal is received from the base station in response to the first signal. In an embodiment, the electronic device may identify whether the second signal is received in response to the first signal via the RF circuit. In an embodiment, the electronic device may identify whether the second signal is received in response to the first signal via the RF circuit within a set time period (e.g., a time period indicated by a parameter ra-ResponseWindow). In an embodiment, the parameter ra-ResponseWindow may, for example, indicate a Msg2 (RAR) window length indicated by a network, and the Msg2 (RAR) window length may be, for example, a time period which corresponds to a set number of slots.

As a result of identifying in operation 617, if the second signal is not received, the electronic device may identify whether a set condition is satisfied in operation 619. In an embodiment, the set condition may, for example, include a condition in which the first transmission power is equal to threshold transmission power. The threshold transmission power may include maximum transmission power (Max Tx power) which the electronic device may use to transmit the first signal.

As a result of identifying in operation 619, if the set condition is satisfied, the electronic device may change the setting value from the first setting value to a second setting value in operation 621. In an embodiment, the second setting value may be a setting value other than the first setting value among setting values (e.g., the first setting value and the second setting value) settable for a frequency used in the RF circuit. In an embodiment, the second setting value may be a setting value for the frequency used in the RF circuit which is set to correspond to a second status different from the first status of the grip sensor corresponding to the first setting value. In an embodiment, a case in which the second signal is not received in response to the first signal even though the set condition is satisfied (e.g., even though the first signal is transmitted using the threshold transmission power (e.g., the maximum transmission power)) may include a case in which degradation in an antenna radiation performance occurs due to degradation in antenna efficiency. If the antenna efficiency is degraded, the antenna radiation performance may be degraded, and the degradation in the antenna radiation performance may cause degradation in a total radiated power (TRP) performance and/or degradation in a total isotropic sensitivity (TIS) performance Therefore, according to an embodiment, antenna efficiency may be improved by changing the setting value (e.g., a tuning value) used in the antenna tuning circuit from the first setting value to the second setting value. As the antenna efficiency is improved, the antenna radiation performance may be improved, so the TRP performance and/or the TIS performance may also be improved. As the TRP performance is improved, if the electronic device transmits the first signal based on the first transmission power and the second setting value, a probability that the first signal will reach (be received at) a base station may be increased compared to a case in which the electronic device transmits the first signal based on the first transmission power and the first setting value.

In operation 623, the electronic device may transmit the first signal to the base station based on the first transmission power and the second setting value. In an embodiment, the electronic device may control the RF circuit to transmit the first signal based on the first transmission power and the second setting value.

In FIG. 6, the operation of the electronic device has been described by taking an example of the operation when the electronic device in the RRC_IDLE state or the RRC_INACTIVE state performs the random access procedure. An electronic device in an RRC_CONNECTED state may also operate in a form similar to that described in FIG. 6 when performing a random access procedure. The electronic device exists in the RRC_CONNECTED state, so operations 611 and 613 may be omitted. As operations 611 and 613 are omitted, the first setting value in operation 615 may be a setting value of the at least one antenna tuning circuit at a time point at which the first signal is transmitted which is not a setting value of the at least one antenna tuning circuit before transition to the RRC_IDLE state or the RRC_INACTIVE state. So, operations when the electronic device in the RRC_CONNECTED state performs the random access procedure may be similar to or substantially the same as operations 615 to 623.

FIG. 7 is a diagram for describing a setting value used for controlling an example antenna tuning circuit according to various embodiments.

Referring to FIG. 7, if a dielectric approaches or is in proximity to an antenna (e.g., an antenna 460 in FIG. 4) of an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4), impedance of the antenna may change, accordingly an RF performance may be degraded. Due to degradation in the RF performance, antenna efficiency per frequency may also be degraded. In order to compensate for the degradation in the antenna efficiency, a setting value (e.g., a tuning value) of an antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4) may be changed.

A reference numeral 711 is a graph showing a change in antenna efficiency in a free space status, a reference numeral 713 is a graph showing a change in antenna efficiency in a grip status, and a reference numeral 715 is a graph showing a change in antenna efficiency based on a tuning value in the grip status (grip+tunable antenna update) (a grip touch mode).

As shown in FIG. 7, in the grip state due to the approach of or proximity of the dielectric, antenna efficiency per frequency of the electronic device may change, so antenna efficiency at a target frequency (Target freq.) may also change.

If the antenna efficiency is degraded, a radiation performance of the antenna may be degraded. The degradation in the radiation performance of the antenna may cause degradation in a total radiated power (TRP) performance and/or degradation in a total isotropic sensitivity (TIS) performance. In an embodiment, the TRP performance may be related to a transmission performance of the electronic device, and the TIS performance may be related to a reception performance of the electronic device.

So, the antenna efficiency may be improved by changing the setting value (e.g., the tuning value) used in the antenna tuning circuit according to a structure of the antenna and the antenna tuning circuit. As the antenna efficiency is improved, the radiation performance of the antenna may be improved, and thus the TRP performance and/or the TIS performance may also be improved.

Because the change in the antenna efficiency per frequency due to the approach of or proximity of the dielectric is a characteristic of the electronic device, the change in the antenna efficiency per frequency due to the approach of the dielectric may be identified, for example, in advance. For example, the electronic device may identify in advance a change in antenna efficiency per frequency due to approach of or proximity of the dielectric in a laboratory environment. So, the electronic device may store in advance a setting value to be used by the antenna tuning circuit in the grip status and a setting value to be used by the antenna tuning circuit in the free space status based on the change in the antenna efficiency per frequency due to the approach of or proximity of the dielectric. In an embodiment, the electronic device may store setting values to be used by the antenna tuning circuit in advance in a form of a table including the setting value to be used by the antenna tuning circuit in the grip status and the setting value to be used by the antenna tuning circuit 440 in the free space status per frequency.

FIG. 8 is a diagram for describing an example operation of an example electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state according to various embodiments.

Prior to describing FIG. 8, it may be noted that an operation of an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) described in FIG. 8 is an operation of the electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state.

Referring to FIG. 8, the electronic device may identify whether a paging signal targeting the electronic device is received from a serving cell based on a set period (e.g., a first period), and perform a measurement operation for the serving cell. The electronic device may perform a measurement operation for a neighbor cell based on a set period (e.g., a second period).

In FIG. 8, time periods 811, 815, 817, and 821 marked with “P” may refer, for example, to a time period during which the electronic device identifies whether a paging signal targeting the electronic device is received from the serving cell, and performs the measurement operation for the serving cell, and time periods 813 and 819 marked with “M” may refer to a time period during which the electronic device performs the measurement operation for the neighboring cell.

The electronic device may maintain a setting value of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4 or 5) before transition to the RRC_IDLE state or the RRC_INACTIVE state. If grip status information before transition to the RRC_IDLE state or the RRC_INACTIVE state indicates grip touch status, the setting value may be a setting value used by at least one antenna tuning circuit in grip status for a frequency used in an RF circuit (e.g., an RF circuit 450 in FIG. 5) including the at least one antenna tuning circuit connected to at least one antenna (e.g., an antenna 460 in FIG. 4). If the grip status information before transition to the RRC_IDLE state or the RRC_INACTIVE state indicates grip release status, the setting value may be a setting value used by the at least one antenna tuning circuit in free space status for the frequency used in the RF circuit.

While maintaining the setting value of the at least one antenna tuning circuit before the transition to the RRC_IDLE state or the RRC_INACTIVE state, the electronic device may identify whether the paging signal is received, perform the measurement operation for the serving cell, and perform the measurement operation for the neighbor cell. As such, the measurement operation which the electronic device performs while maintaining the setting value of the at least one antenna tuning circuit before the transition to the RRC_IDLE state or the RRC_INACTIVE state (e.g., at least one of the measurement operation for the serving cell and the measurement operation for the neighbor cell) will be referred to, for example, as a “normal measurement operation”.

The electronic device which is in the RRC_IDLE state or RRC_INACTIVE state may determine whether to transit to a sleep state or wake up based on a discontinuous reception (DRX) cycle. The electronic device may identify on-duration based on the DRX cycle, identify whether the paging signal targeting the electronic device is received in an awake state during the on-duration, and perform the measurement operation for the serving cell. In an embodiment, the on-duration may include a duration in which the electronic device waits to receive physical downlink control channels (PDCCHs) after waking up. When the on-duration expires, the electronic device may transit to the sleep state or perform the measurement operation for the neighbor cell based on radio resource management (RRM) configuration. In FIG. 8, the time period marked “P” may correspond to the on-duration.

FIG. 9 is a diagram for describing an example operation of an example electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state according to various embodiments.

Prior to describing FIG. 9, it may be noted that an operation of an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) described in FIG. 9 is an operation of the electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state.

Referring to FIG. 9, the electronic device may identify whether a paging signal targeting the electronic device is received from a serving cell based on a set period (e.g., a first period), perform a measurement operation for the serving cell, and perform a measurement operation for a neighbor cell based on a set period (e.g., a second period) as described in FIG. 8.

A reason why the electronic device performs the measurement operation for the neighbor cell may be mainly related to a mobility issue such as a handover. So, if the electronic device exists in a stationary environment rather than a mobility environment, the electronic device may skip the measurement operation for the neighbor cell. According to an embodiment, the electronic device may skip the measurement operation for the neighbor cell in a time period in which the measurement operation for the neighbor cell is set to be performed, change a setting value (e.g., a tuning value) of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4) which is currently set from a first setting value to a second setting value, and perform the measurement operation for the serving cell based on the second setting value.

In an embodiment, the first setting value may be a setting value which corresponds to grip status information before the electronic device transits to the RRC_IDLE state or the RRC_INACTIVE state. For example, if the grip status information indicates grip touch status, the first setting value may be a setting value used by the at least one antenna tuning circuit in grip status for a frequency used in an RF circuit (e.g., an RF circuit 450 in FIG. 5). If the grip status information before transition to the RRC_IDLE state or the RRC_INACTIVE state indicates grip release status, the first setting value may be a setting value used by the at least one antenna tuning circuit in free space status for the frequency used in the RF circuit.

In an embodiment, the second setting value may be a setting value considering grip status information which is different from (for example, opposite to) the grip status information considered for the first setting value. If the grip status information considered for the first setting value indicates the grip touch status, the second setting value may be a setting value set for a frequency used in the RF circuit if the grip status information indicates grip release status. If the grip status information considered for the first setting value indicates the grip release status, the second setting value may be a setting value set for the frequency used in the RF circuit if the grip status information indicates the grip touch status.

A reason why the measurement operation for the neighbor cell is skipped in the time period in which the measurement operation for the neighbor cell is set to be performed, and the measurement operation for the serving cell is performed based on the second setting value other than the first setting value before transition to the RRC_IDLE state or the RRC_INACTIVE state may be as follows.

The grip sensor consumes current when being turned on, so the electronic device may turn on or turn off the grip sensor according to a state of the electronic device. To prevent current consumption due to the turn-on of the grip sensor, the electronic device may turn off the grip sensor if the state of the electronic device is the RRC_IDLE state or the RRC_INACTIVE state, and may turn on the grip sensor if the state of the electronic device is the RRC_CONNECTED state.

As such, if the state of the electronic device is the RRC_IDLE state or the RRC_INACTIVE state, the grip sensor may be turned off. So, the electronic device may not operate the at least one antenna tuning circuit based on the approach of or proximity of the dielectric sensed by the grip sensor, and as a result, performance degradation in a receiving operation of the electronic device, such as an operation of receiving a paging signal, may occur, and performance degradation in a transmitting operation of the electronic device, such as a case in which the electronic device performs a random access procedure in the RRC_IDLE state, may also occur.

Therefore, in the disclosure, in order to prevent (or in order to mitigate) degradation in a transmission performance and a reception performance due to turn-off of a grip sensor from occurring even though the grip sensor is turned off when a state of an electronic device is transited to an RRC_IDLE state or an RRC_INACTIVE state, the electronic device may skip a measurement operation for a neighbor cell in a time period in which the measurement operation for the neighbor cell is set to be performed and perform a measurement operation for a serving cell based on a second setting value other than a first setting value before transition to the RRC_IDLE state or the RRC_INACTIVE state if a set condition is satisfied (for example, if a stationary condition is satisfied).

As such, the measurement operation (e.g., the measurement operation for the serving cell), which the electronic device performs using the at least one antenna tuning circuit whose setting value is changed to the second setting value after changing the setting value of the at least one antenna tuning circuit from the first setting value to the second setting value if the set condition is satisfied (for example, if the stationary condition is satisfied) in order to prevent (or in order to mitigate) the degradation in the transmission performance and the reception performance due to the turn-off of the grip sensor from occurring even though the grip sensor is turned off when the state of the electronic device is transited to the RRC_IDLE state or the RRC_INACTIVE state, will be referred to, for example, as a “temporary measurement operation”.

In FIG. 9, time periods 911, 915, 917, and 921 marked with “P” may represent a time period in which the electronic device identifies whether a paging signal targeting the electronic device is received from the serving cell, and performs the measurement operation for the serving cell, a time period 913 marked with “M” may represent a time period in which the electronic device performs the measurement operation for the neighbor cell, and a time period 919 marked with “A” may represent a time period which is originally set to perform the measurement operation for the neighbor cell, however, in which the electronic device performs the measurement operation (e.g., the temporary measurement operation) for the serving cell based on the second setting value (e.g., the changed tuning value) as the electronic device exists in a stationary environment.

In an embodiment, the temporary measurement operation may be performed based on a set ratio. For example, if the set ratio is 50%, the temporary measurement operation may be performed in one time period corresponding to 50% of time periods in which the measurement operation for the neighbor cell is set to be performed. In an embodiment, the set ratio may be determined based on various parameters suitable for a situation of a wireless communication network.

FIG. 10 is a flow chart illustrating an example operating process of an example electronic device according to various embodiments

Referring to FIG. 10, an electronic device (e.g., an electronic device 101 in FIGS. 1, 2A, 2B, and 3A to 3C) (e.g., a processor 120 in FIG. 1, a first communication processor 212 or a second communication processor 214 in FIG. 2A, an integrated communication processor 260 in FIG. 2B, or a communication processor 260 in FIG. 4) may transit to an RRC_IDLE state in operation 1011.

After transiting to the RRC_IDLE state or an RRC_INACTIVE state, the electronic device may turn off a grip sensor (e.g., a grip sensor 410 in FIG. 4) in operation 1013.

In operation 1015, the electronic device may maintain a first setting value which is a setting value of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4 or 5) before transition to the RRC_IDLE state or the RRC_INACTIVE state. If grip status information before the transition to the RRC_IDLE state or the RRC_INACTIVE state indicates grip touch status, the first setting value may be a setting value used by at least one antenna tuning circuit in grip status for a frequency used in an RF circuit (e.g., an RF circuit 450 in FIG. 5) including the at least one antenna tuning circuit connected to at least one antenna (e.g., an antenna 460 in FIG. 4). If the grip status information before the transition to the RRC_IDLE state or the RRC_INACTIVE state indicates grip release status, the first setting value may be a setting value used by the at least one antenna tuning circuit in free space status for the frequency used in the RF circuit. Operation 1015 may be implemented similarly to or substantially the same as operation 613 in FIG. 6, so a detailed description thereof will not be repeated here.

In operation 1017, the electronic device may identify whether a stationary condition is satisfied. In an embodiment, the stationary condition may, for example, include a condition in which the electronic device may be identified as being in stationary state.

In an embodiment, the electronic device may identify whether the electronic device is in the stationary state via a sensor hub (e.g., a sensor module 176 in FIG. 1).

In an embodiment, the electronic device may identify whether the electronic device is in the stationary state based on at least one of an acceleration signal or an angular velocity signal obtained via the sensor hub. In an embodiment, if a change amount of the at least one of the acceleration signal or the angular velocity signal is less than a threshold change amount, the electronic device may identify that the electronic device is in the stationary state. In an embodiment, a case of identifying whether the electronic device is in the stationary state based on the at least one of the acceleration signal or the angular velocity signal is described as an example, however, whether the electronic device is in the stationary state may be identified based on signals sensed in a plurality of sensors included in the sensor hub.

In an embodiment, the electronic device may identify whether the electronic device is in the stationary state based on a cell identifier (ID) of a serving cell and signal strength of the serving cell. In an embodiment, the electronic device may identify that the electronic device is in the stationary state if a difference between signal strength of the serving cell measured in an RRC_CONNECTED state immediately before transition to the RRC_IDLE state or the RRC_INACTIVE state without a cell identifier (ID) of the serving cell being changed and signal strength of the served cell measured in the RRC_IDLE state or the RRC_INACTIVE state is less than a threshold value (e.g., 10 dB). In an embodiment, signal strength may include at least one of reference signal received power (RSRP), a received strength signal indicator (RSSI), reference signal received quality (RSRP), received signal code power (RSCP), a signal to noise ratio (SNR), or a signal to interference plus noise ratio (SINR).

As a result of identifying in operation 1017, if the stationary condition is not satisfied, the electronic device may perform a first measurement operation (e.g., a normal measurement operation) in operation 1019. The normal measurement operation may be implemented similarly to or substantially the same as that described in FIG. 8, so a detailed description thereof will not be repeated here.

As a result of identifying in operation 1017, if the stationary condition is satisfied, the electronic device may change the setting value of the at least one antenna tuning circuit from the first setting value to a second setting value in operation 1021. In an embodiment, the second setting value may be a setting value considering grip status information which is different from (for example, opposite to) the grip status information considered for the first setting value. If the grip status information considered for the first setting value indicates, for example, the grip touch status, the second setting value may be a setting value set for a frequency used in the RF circuit if the grip status information indicates grip release status. If the grip status information considered for the first setting value indicates, for example, the grip release status, the second setting value may be a setting value set for the frequency used in the RF circuit if the grip status information indicates the grip touch status.

In operation 1023, the electronic device may perform a second measurement operation (e.g., a temporary measurement operation) based on the second setting value. The temporary measurement operation may be implemented similarly to or substantially the same as that described in FIG. 9, so a detailed description thereof will not be repeated here.

In operation 1025, the electronic device may identify whether a reception performance is improved. In an embodiment, the electronic device may identify whether the reception performance is improved based on whether signal strength of the serving cell measured through the temporary measurement operation is stronger than signal strength of the serving cell measured through the normal measurement operation by threshold signal strength or more. For example, the electronic device may identify that the reception performance is improved if the signal strength of the serving cell measured through the temporary measurement operation is stronger than the signal strength of the serving cell measured through the normal measurement operation by the threshold signal strength or more. In FIG. 10, a case in which the electronic device identifies whether the reception performance is improved via the temporary measurement operation has been described as an example, however, the electronic device may identify whether reception imbalance is improved through the temporary measurement operation. In an embodiment, the electronic device may identify whether the reception imbalance is improved based on whether a difference between the signal strength of the serving cell measured through the temporary measurement operation and the signal strength of the serving cell measured through the normal measurement operation decreases by a threshold value or more. For example, if a difference between RSRP of the serving cell measured through the temporary measurement operation and RSRP of the serving cell measured through the normal measurement operation decreases by a threshold value (e.g., 2 dB) or more, it may be identified that the reception imbalance is improved.

In an embodiment, a case in which the electronic device includes one grip sensor (e.g., the grip sensor 410 in FIG. 4) has been described as an example, however, the electronic device may include two or more grip sensors. For example, if the electronic device includes two grip sensors, one of the two grip sensors may be used as a main grip sensor and the other grip sensor may be used as a sub grip sensor. For example, the main grip sensor may be a grip sensor disposed on a lower side of the electronic device, and the sub grip sensor may be a grip sensor disposed on an upper side of the electronic device. In a case in which the electronic device includes the two grip sensors, similarly to a case in which the electronic device includes the one grip sensor, the electronic device may perform a measurement operation while controlling a sensor value of at least one antenna tuning circuit corresponding to each grip sensor to the first setting value or the second setting value.

Table 1 below shows signal strength (e.g., RSRP) of the serving cell obtained via an antenna corresponding to the main grip sensor and signal strength of the serving cell obtained via an antenna corresponding to the sub grip sensor in a case in which the electronic device includes the two grip sensors.

In Table 1, it may be seen that a difference between signal strength of the serving cell obtained via the antenna corresponding to the main grip sensor and signal strength of the serving cell obtained via the antenna corresponding to the sub grip sensor in a case in which the first setting value is applied decreases by a threshold value (e.g., 2 dB) or more compared to a difference between signal strength of the serving cell obtained via the antenna corresponding to the main grip sensor and signal strength of the serving cell obtained via the antenna corresponding to the sub grip sensor in a case that the second setting value is applied. For example, as shown in Table 1, a gain of 3 dB occurs in the antenna corresponding to the main grip sensor, so the electronic device may identify that a reception performance is improved. As a result of identifying in operation 1025, if the reception performance is improved, the electronic device may maintain the setting value of the at least one antenna tuning circuit as the second setting value in operation 1029.

As the result of identifying in operation 1025, if the reception performance is not improved, the electronic device may change the setting value of the at least one antenna tuning circuit from the second setting value to the first setting value in operation 1027.

FIG. 11 is a diagram for describing an example operation of an example electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state according to various embodiments.

Prior to describing FIG. 11, it will be noted that an operation of an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) described in FIG. 11 may be an operation of performing a random access procedure in the electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state.

Referring to FIG. 11, a vertical axis represents transmission power (Tx power), and a horizontal axis represents time. In FIG. 11, “A” may represent, for example, a random access preamble signal. In FIG. 11, “B” may represent, for example, a random access response window, and the random access response window may represent, for example, a time period indicated by a parameter ra-ResponseWindow. The electronic device may transit to the RRC_IDLE state or the RRC_INACTIVE state. In an embodiment, the electronic device may turn off a grip sensor (e.g., a grip sensor 410 in FIG. 4) when transiting to the RRC_IDLE state or the RRC_INACTIVE state.

After transiting to the RRC_IDLE state or the RRC_INACTIVE state, the electronic device may maintain a first setting value which is a setting value of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4 or 5) which corresponds to the grip sensor before transition to the RRC_IDLE state or the RRC_INACTIVE state. If grip status information before transition to the RRC_IDLE state or the RRC_INACTIVE state indicates, for example, grip touch status, the first setting value may be a setting value used by at least one antenna tuning circuit in grip status for a frequency used in an RF circuit (e.g., an RF circuit 450 in FIG. 5) including the at least one antenna tuning circuit connected to at least one antenna (e.g., an antenna 460 in FIG. 4). If the grip status information before transition to the RRC_IDLE state or the RRC_INACTIVE state indicates, for example, grip release status, the first setting value may be a setting value used by the at least one antenna tuning circuit in free space status for the frequency used in the RF circuit.

The electronic device in the RRC_IDLE state or the RRC_INACTIVE state may transmit a first signal for a random access based on first transmission power and the first setting value. In an embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number of times indicated by a parameter preambleTransMax) until a second signal is received. In an embodiment, the parameter preambleTransMax may indicate a maximum number of times for transmission of the first signal performed before failure of the random access procedure is declared.

In an embodiment, the first signal may include a random access preamble signal. In an embodiment, the first signal may include the random access preamble signal and data by first scheduled transmission in a random access procedure. In an embodiment, if the electronic device performs a 4-step random access procedure, the first signal may include the random access preamble signal. In an embodiment, if the electronic device performs a 2-step random access procedure, the first signal may include the random access preamble signal and the data by the first scheduled transmission. In an embodiment, the second signal may be a response signal to the first signal. In an embodiment, the second signal may, for example, include an RAR signal. In an embodiment, the second signal may include the RAR signal and contention resolution. In an embodiment, if the electronic device performs the 4-step random access procedure, the second signal may, for example, include the RAR signal. In an embodiment, if the electronic device performs the 2-step random access procedure, the second signal may, for example, include the RAR signal and the contention resolution.

Even though transmitting the random access preamble signal (marked as “A” in FIG. 11) based on the first transmission power which is maximum transmission power (Max power) and the first setting value, the electronic device may not receive the RAR signal within a set time period (marked as “B” in FIG. 11) (e.g., a time period indicated by a parameter ra-ResponseWindow). In this case, before it reaches the number of times indicated by the parameter preambleTransMax, the electronic device may change the setting value of the at least one antenna tuning circuit from the first setting value to the second setting value, and transmit the random access preamble signal based on the second setting value and the first transmission power until the RAR is received (operations 1111, 1113, and 1115). In FIG. 11, a condition in which the second setting value is applied may include a condition in which the first transmission power is equal to threshold transmission power. The threshold transmission power may be maximum transmission power which the electronic device may use to transmit the first signal.

In an embodiment, the second setting value may be a setting value considering grip status information which is different from (for example, opposite to) the grip status information considered for the first setting value. If the grip status information considered for the first setting value indicates, for example, the grip touch status, the second setting value may be a setting value set for a frequency used in the RF circuit if the grip status information indicates grip release status. If the grip status information considered for the first setting value indicates, for example, the grip release status, the second setting value may be a setting value set for the frequency used in the RF circuit if the grip status information indicates the grip touch status.

In FIG. 11, the operation of the electronic device has been described by taking an example of the operation when the electronic device in the RRC_IDLE state or the RRC_INACTIVE state performs the random access procedure. An electronic device in an RRC_CONNECTED state may also operate in a form similar to that described in FIG. 11 when performing a random access procedure. However, the electronic device exists in the RRC_CONNECTED state, so the first setting value may be a setting value of the at least one antenna tuning circuit at a time point at which the first signal is transmitted which is not a setting value of the at least one antenna tuning circuit before transition to the RRC_IDLE state or the RRC_INACTIVE state.

FIG. 12 is a diagram for describing an example operation of an example electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state according to various embodiments.

Prior to describing FIG. 12, it will be noted that an operation of an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) described in FIG. 12 may be an operation of performing a random access procedure in the electronic device which is in an RRC_IDLE state or an RRC_INACTIVE state.

Referring to FIG. 12, a vertical axis represents transmission power (Tx power), and a horizontal axis represents time. In FIG. 12, “A” may, for example, represent a random access preamble signal. In FIG. 12, “B” may, for example, represent a random access response window, and the random access response window may, for example, represent a time period indicated by a parameter ra-ResponseWindow. The operation of performing the random access procedure by the electronic device shown in FIG. 12 may be performed similarly to or substantially the same as an operation of performing a random access procedure by an electronic device described in FIG. 11 except for a time point at which a second setting value of at least one antenna tuning circuit is applied. In FIG. 11, a case has been described in which the electronic device changes a setting value of the at least one antenna tuning circuit from a first setting value to the second setting value if the electronic device does not receive an RAR signal within a set time period even though transmitting a random access preamble signal based on first transmission power which is maximum transmission power and the first setting value.

However, in FIG. 12, a case is described in which the electronic device changes the setting value of the at least one antenna tuning circuit from the first setting value to the second setting value even though the electronic device does not receive the RAR signal within the set time period after transmitting the random access preamble signal based on second transmission power less than the first transmission power which is the maximum transmission power and the first setting value (operations 1211, 1213, 1215, 1217, and 1219).

In FIG. 12, a condition in which the second setting value is applied may include a condition in which the first transmission power is less than threshold transmission power. The threshold transmission power may be maximum transmission power which the electronic device may use to transmit the first signal.

In FIG. 12, the operation of the electronic device has been described by taking an example of the operation when the electronic device in the RRC_IDLE state or the RRC_INACTIVE state performs the random access procedure. An electronic device in an RRC_CONNECTED state may also operate in a form similar to that described in FIG. 12 when performing a random access procedure. However, the electronic device exists in the RRC_CONNECTED state, so the first setting value may be a setting value of the at least one antenna tuning circuit at a time point at which the first signal is transmitted which is not a setting value of the at least one antenna tuning circuit before transition to the RRC_IDLE state or the RRC_INACTIVE state.

FIG. 13 is a flow chart illustrating an example operating method of an example electronic device according to various embodiments.

Referring to FIG. 13, an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) (e.g., a processor 120 in FIG. 1, a first communication processor 212 or a second communication processor 214 in FIG. 2A, or an integrated communication processor 260 in FIG. 2B or 4) which is in an RRC_CONNECTED state may transmit a first signal for a random access based on a first setting value which is a setting value of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4 or 5) which corresponds to a grip sensor (e.g., a grip sensor 410 in FIG. 4) and first transmission power in operation 1311. If grip status information indicates, for example, grip touch status, the first setting value may be a setting value used by the at least one antenna tuning circuit in grip status for a frequency used in an RF circuit (e.g., an RF circuit 450 in FIG. 5) including the at least one antenna tuning circuit connected to at least one antenna (e.g., an antenna 460 in FIG. 4). If the grip status information indicates, for example, grip release status, the first setting value may be a setting value used by the at least one antenna tuning circuit in free space status for the frequency used in the RF circuit.

In operation 1311, the electronic device may transmit a first signal for a random access based on first transmission power and the first setting value. In an embodiment, the electronic device may control the RF circuit to transmit the first signal for the random access based on the first transmission power and the first setting value. In an embodiment, the first signal may include a random access preamble signal. In an embodiment, the first signal may include the random access preamble signal and data by first scheduled transmission in a random access procedure. In an embodiment, if the electronic device performs a 4-step random access procedure, the first signal may include the random access preamble signal. In an embodiment, if the electronic device performs a 2-step random access procedure, the first signal may include the random access preamble signal and the data by the first scheduled transmission. In an embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number of times indicated by a parameter preambleTransMax) until a second signal is received. So, operation 1311 may be performed only until the maximum number of times for transmission of the first signal is reached. In an embodiment, the second signal may, for example, be a response signal to the first signal. In an embodiment, the second signal may include an RAR signal. In an embodiment, the second signal may include the RAR signal and contention resolution. In an embodiment, if the electronic device performs the 4-step random access procedure, the second signal may include the RAR signal. In an embodiment, if the electronic device performs the 2-step random access procedure, the second signal may include the RAR signal and the contention resolution.

In operation 1313, the electronic device may identify whether the second signal is received in response to the first signal. In an embodiment, the electronic device may identify whether the second signal is received in response to the first signal via the RF circuit. In an embodiment, the electronic device may identify whether the second signal is received in response to the first signal via the RF circuit within a set time period (e.g., a time period indicated by a parameter ra-ResponseWindow).

As a result of identifying in operation 1313, if the second signal is not received, the electronic device may identify whether a set condition is satisfied in operation 1315. In an embodiment, the set condition may include a first condition in which the first transmission power is equal to threshold transmission power. The threshold transmission power may be maximum transmission power which the electronic device may use to transmit the first signal. In an embodiment, the set condition may include a second condition in which the first transmission power is less than the threshold transmission power.

As a result of identifying in operation 1315, if the set condition is satisfied, the electronic device may change the setting value from the first setting value to a second setting value in operation 1317. In an embodiment, the second setting value may be a setting value, for example, considering grip status information which is different from (for example, opposite to) the grip status information considered for the first setting value. If the grip status information considered for the first setting value indicates, for example, the grip touch status, the second setting value may be a setting value set for a frequency used in the RF circuit if the grip status information indicates grip release status. If the grip status information considered for the first setting value indicates, for example, the grip release status, the second setting value may be a setting value set for the frequency used in the RF circuit if the grip status information indicates the grip touch status.

In operation 1319, the electronic device may transmit the first signal based on the first transmission power or the second transmission power, and the second setting value. In an embodiment, the electronic device may control the RF circuit to transmit the first signal based on the first transmission power or the second transmission power, and the second setting value. In an embodiment, if the set condition is the first condition, the electronic device may control the RF circuit to transmit the first signal based on the first transmission power and the second setting value. In an embodiment, if the set condition is the second condition, the electronic device may control the RF circuit to transmit the first signal based on the second transmission power and the second setting value.

According to an embodiment of the disclosure, the grip sensor (e.g., the grip sensor 410 in FIG. 4) may sense additional status such as hard grip status and death grip status as well as the grip touch status and the grip release status.

Table 2 below shows grip status which may be sensed by the grip sensor.

TABLE 2

Grip status
Description

Grip release
Free space status

Grip touch
General grip status

Hard grip
Status in which a user grabs an antenna, and then a

change in antenna efficiency is greater than or equal

to a first threshold amount

Death grip
Status in which a user grips a specific part of an antenna,

and then a change in antenna efficiency is greater than or

equal to a second threshold amount

As shown in Table 2, grip status sensed via the grip sensor may be various, and the setting value for the at least one antenna tuning circuit (e.g., the antenna tuning circuit 440 in FIG. 4 or 5) may be determined by applying all of the grip status sensed via the grip sensor. In this case, a table including setting values to be used by the antenna tuning circuit may include setting values corresponding to the hard grip status and the death grip status as well as the grip touch status and the grip release status.

In an embodiment, in a case in which the setting value to be used by the antenna tuning circuit is determined by considering only the grip touch status and the grip release status, if grip status corresponding to the first setting value is the grip touch status, grip status corresponding to the second setting value may be the grip releasing state.

In an embodiment, in a case in which the setting value to be used by the antenna tuning circuit is determined by considering the grip touch status, the grip release status, the hard grip status, and the death grip status, if grip status corresponding to the first setting value is the grip touch status, grip status corresponding to the second setting value may be one of the grip releasing state, the hard grip status, and the death grip status.

FIG. 14 is a flow chart illustrating an example operating method of an example electronic device according to various embodiments.

Referring to FIG. 14, an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) (e.g., a processor 120 in FIG. 1, a first communication processor 212 or a second communication processor 214 in FIG. 2A, or an integrated communication processor 260 in FIG. 2B or 4) may transmit a first signal for a random access to a base station based on first transmission power and a first setting value in operation 1411. In an embodiment, a setting value may include a tuning value of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4 or 5). In an embodiment, the electronic device may control the RF circuit to transmit the first signal for the random access based on the first transmission power and the first setting value. In an embodiment, the first signal may include a random access preamble signal. In an embodiment, the first signal may include the random access preamble signal and data by first scheduled transmission in a random access procedure. In an embodiment, if the electronic device performs a 4-step random access procedure, the first signal may include the random access preamble signal. In an embodiment, if the electronic device performs a 2-step random access procedure, the first signal may include the random access preamble signal and the data by the first scheduled transmission. In an embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number of times indicated by a parameter preambleTransMax) until a second signal is received in response to the first signal. In an embodiment, the parameter preambleTransMax may indicate the maximum number of times for transmission of the first signal performed before failure of the random access procedure is declared. So, operation 1411 may be performed only until the maximum number of times for transmission of the first signal is reached. In an embodiment, the second signal may be a response signal to the first signal. In an embodiment, the second signal may include an RAR signal. In an embodiment, the second signal may include the RAR signal and contention resolution. In an embodiment, if the electronic device performs the 4-step random access procedure, the second signal may include the RAR signal. In an embodiment, if the electronic device performs the 2-step random access procedure, the second signal may include the RAR signal and the contention resolution.

In operation 1413, the electronic device may identify whether the second signal is received from the base station in response to the first signal. In an embodiment, the electronic device may identify whether the second signal is received in response to the first signal via the RF circuit. In an embodiment, the electronic device may identify whether the second signal is received in response to the first signal via the RF circuit within a set time period (e.g., a time period indicated by a parameter ra-ResponseWindow). In an embodiment, the parameter ra-ResponseWindow may indicate a Msg2 (RAR) window length indicated by a network, and the Msg2 (RAR) window length may be, for example, a time period which corresponds to a set number of slots.

As a result of identifying in operation 1413, if the second signal is not received, the electronic device may identify whether a set condition is satisfied in operation 1415. In an embodiment, the set condition may include a first condition in which the first transmission power is equal to threshold transmission power. The threshold transmission power may include maximum transmission power (Max Tx power) which the electronic device may use to transmit the first signal.

As a result of identifying in operation 1415, if the set condition is satisfied, the electronic device may change the setting value from the first setting value to a second setting value in operation 1417. In an embodiment, the second setting value may be a setting value other than the first setting value among setting values (e.g., the first setting value and the second setting value) settable for a frequency used in the RF circuit. In an embodiment, the second setting value may be a setting value for the frequency used in the RF circuit which is set to correspond to a second status different from the first status of the grip sensor corresponding to the first setting value.

In an embodiment, a case in which the second signal is not received in response to the first signal even though the set condition is satisfied (e.g., even though the first signal is transmitted using the threshold transmission power (e.g., the maximum transmission power)) may include a case in which degradation in an antenna radiation performance occurs due to degradation in antenna efficiency. If the antenna efficiency is degraded, the antenna radiation performance may be degraded, and the degradation in the antenna radiation performance may cause degradation in a total radiated power (TRP) performance and/or degradation in a total isotropic sensitivity (TIS) performance Therefore, according to an embodiment, antenna efficiency may be improved by changing the setting value (e.g., a tuning value) used in the antenna tuning circuit from the first setting value to the second setting value. As the antenna efficiency is improved, the antenna radiation performance may be improved, so the TRP performance and/or the TIS performance may also be improved. As the TRP performance is improved, if the electronic device transmits the first signal based on the first transmission power and the second setting value, a probability that the first signal will reach (be received at) a base station may be increased compared to a case in which the electronic device transmits the first signal based on the first transmission power and the first setting value.

In operation 1419, the electronic device may transmit the first signal to the base station based on the first transmission power and the second setting value. In an embodiment, the electronic device may control the RF circuit to transmit the first signal based on the first transmission power and the second setting value.

According to an example embodiment of the disclosure, an operating method of an electronic device (e.g., an electronic device 101 in FIG. 1, 2A, 2B, 3A to 3C, or 4) may include transiting to a radio resource control (RRC) idle (RRC_IDLE) state or an RRC inactive (RRC_INACTIVE) state, and maintaining a first tuning value which is a tuning value of at least one antenna tuning circuit (e.g., an antenna tuning circuit 440 in FIG. 4) which corresponds to a grip sensor (e.g., a grip sensor 410 in FIG. 4) before transition to the RRC_IDLE state or the RRC_INACTIVE.
