This application is based on and claims priority under 35 U.S.C. § 119(a) to Korean Patent Application No. 10-2019-0046270, filed on Apr. 19, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The disclosure relates to a method for controlling power in legacy and 5th generation (5G) communication and an electronic device therefor.
An electronic device may support cellular communication. For example, the cellular communication may use a wireless protocol according to a communication standard specified by 3rd generation partnership project (3GPP). With the development of the communication standard, the range of a frequency band used by the electronic device has increased.
The electronic device may simultaneously transmit a plurality of signals corresponding to a plurality of frequency bands to increase the transmission rate of data transmitted through an uplink. The efficiency of radio resource use and scheduling flexibility may be increased through simultaneous transmission in a plurality of frequency bands that are continuous or non-continuous. For example, the electronic device may utilize a plurality of frequency bands belonging to the same radio access technology (RAT) or may utilize a plurality of frequency bands belonging to different RATs.
An electronic device may simultaneously perform uplink transmission using a plurality of frequency bands. The transmission of the signal in the first band of the electronic device may operate as interference to the signal in the second band of the electronic device. For example, the harmonic component in the first band signal may correspond to at least part of the second band. The electronic device may reduce the maximum transmission power to reduce signal interference. The limitation of the maximum transmission power may reduce the uplink transmission quality of the electronic device.
The electronic device may transmit a signal using the first band and may receive a signal using the second band at the same time. The harmonic component of the first band transmission signal may operate as the interference to the reception of the second band signal. For example, the harmonic component of the first band signal may cause reception sensitivity degradation (e.g., desense) of the second band signal.
In accordance with an aspect of the disclosure, an electronic device is provided that includes a housing, a first antenna, a second antenna, a first wireless communication circuit electrically connected to the first antenna and configured to transmit and/or receive a first signal having a first frequency between 500 MHz and 6 GHz. The electronic device also includes a first power modulator included in the first wireless communication circuit or connected to the first wireless communication circuit and configured to provide the first wireless communication circuit with a first voltage based on envelope tracking (ET) or average power tracking (APT). The electronic device additionally includes a second wireless communication circuit electrically connected to the second antenna and configured to transmit and/or receive a second signal having a second frequency between 500 MHz and 6 GHz, and a second power modulator included in the second wireless communication circuit or connected to the second wireless communication circuit and providing the second wireless communication circuit with a second voltage based on the ET or the APT. The electronic device further includes at least one processor operatively connected to the first wireless communication circuit and the second wireless communication circuit, and a memory operatively connected to the at least one processor or coupled with the at least one processor. The memory may store one or more instructions that, when executed, cause the at least one processor to receive uplink resource information allocated to the electronic device from a base station, via the first wireless communication circuit, and to cause at least one power modulator, from among the first power modulator and the second power modulator to provide a voltage based on the APT, based on at least a number of uplink resource blocks indicated by the uplink resource information.
In accordance with another aspect of the disclosure, a method is provided for controlling power of an electronic device. Uplink resource information allocated to the electronic device from a base station is received via a first wireless communication circuit configured to transmit and/or receive a first signal of 6 GHz or less. A power modulator of the electronic device controls a power of at least one wireless communication circuit, from among the first wireless communication circuit and a second wireless communication circuit configured to transmit and/or receive a second signal of 6 GHz or less, with APT based on at least the number of uplink resource blocks indicated by the uplink resource information.

The first REFE 532 and the second REFE 534 may be implemented with a part of a single chip or a single package. At least one of the first antenna module 542 or the second antenna module 544 may be omitted or may be combined with any other antenna module to process RF signals in a plurality of bands.
The third RFIC 526 and the antenna 548 may be disposed at the same substrate to form a third antenna module 546. For example, the wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main PCB). In this case, the third RFIC 526 may be disposed in a partial region (e.g., on a lower surface) of a second substrate (e.g., a sub PCB) independent of the first substrate, and the antenna 548 may be disposed in another partial region (e.g., on an upper surface) of the second substrate. As such, the third antenna module 546 may be formed. The antenna 548 may include an antenna array capable of being used for beamforming. It is possible to reduce the length of the transmission line between the third RFIC 526 and the antenna 548 by positioning the third RFIC 226 and the antenna 248 on the same substrate. The decrease in the transmission line may make it possible to reduce the loss (or attenuation) of a signal in a high-frequency band (e.g., approximately 6 GHz to approximately 60 GHz) used for the 5G network communication due to the transmission line. For this reason, the electronic device 101 may improve the quality or speed of communication with the second cellular network 594.
The second cellular network 594 (e.g., a 5G network) may be used independently of the first cellular network 592 (e.g., a legacy network) (e.g., stand-alone (SA)) or may be used in conjunction with the first cellular network 292 (e.g., non-stand alone (NSA)). For example, only an access network (e.g., a 5G radio access network (RAN) or a next generation RAN (NG RAN)) may be present in the 5G network, and a core network (e.g., a next generation core (NGC)) may be absent from the 5G network. In this case, the electronic device 101 may access the access network of the 5G network and may then access an external network (e.g., Internet) under control of the core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with the legacy network or protocol information (e.g., New Radio NR protocol information) for communication with the 5G network may be stored in the memory 530 and may be accessed by another component (e.g., the processor 120, the first CP 512, or the second CP 514).
As shown with respect to 601, the wireless communication module 192 includes a power modulator 610 configured to control the power (e.g., voltage) applied to the first RFFE 532 and the second RFFE 534. For example, the power modulator 610 may control the power applied to the first RFFE 532 and the second RFFE 534, based on signals from the first CP 512, the first RFIC 522, and/or the second RFIC 524. The power modulator 610 may control the power applied to the first RFFE 532 under the control of the first CP 512 and/or the first RFIC 522. The power modulator 610 may control the power of the second RFFE 534 under the control of the first CP 512 and/or the second RFIC 524.
As shown with respect to 603, the wireless communication module 192 includes a first power modulator 612 configured to control the power (e.g., voltage) applied to the first RFFE 532 and a second power modulator 614 configured to control the power applied to the second RFFE 534. For example, the first power modulator 612 may control the power of the first RFFE 532 based on the signal from the first CP 512 and/or the first RFIC 522. The second power modulator 614 may control the power of the second RFFE 534 based on a signal from the second CP 514 and/or the second RFIC 524.
Herein, the operations of various electronic devices (e.g., the electronic device 101 of
The power modulator 610 may operate depending on a plurality of operating modes. For example, in the first mode, the power modulator 610 may control the voltage applied to RFFE (e.g., the first RFFE 532 and/or the second RFFE 534) based on envelope tracking (ET). In the second mode, the power modulator 610 may control the voltage applied to RFFE based on average power tracking (APT). Hereinafter, the power applied to RFFE may be referred to as RFFE input voltage or RFFE input power.
Referring to
When the power modulator 610 controls the RFFE input power based on ET, the power modulator 610 may control the RFFE input power based on the peak value of the transmission signal. For example, the power modulator 610 may control the RFFE input power associated with the transmitting circuit depending on the required transmission power at each instant of transmission. The power modulator 610 may control the RFFE input power based at least partly on an envelope 721 formed by the peak values of the transmission signal. For example, the power modulator 610 may obtain a transmission signal from the first RFIC 552 and may control the input power of the first RFFE 532 based at least partly on the envelope 721 of the transmission signal. The power modulator 610 may obtain a transmission signal from the second RFIC 554 and may control the input power of the second RFFE 532 based at least partly on the envelope of the transmission signal.
Referring again to
The electronic device 101 may simultaneously transmit signals, using a plurality of frequency bands. For example, the electronic device 101 may substantially simultaneously transmit a signal, using the first band and the second band. For example, the first band and the second band may be frequency bands associated with the same radio access technology (RAT). In another example, the first band and the second band may be frequency bands associated with different RATs. In this case, at least part of the first band and the second band may overlap with each other on a frequency domain. When the first band and the second band have a specified relationship (e.g., when the multiplication number of the first band corresponds to the second band), the harmonic component of the signal transmitted by the electronic device 101 in the first band may cause the distortion in the signal in the second band.
According to E-UTRAN new radio-dual connectivity (EN-DC), the electronic device 101 may be connected to the first cellular network 592 using the first RFFE 532 and may be connected to the second cellular network 594 using the second RFFE 534. When the electronic device 101 communicates based on frequency division multiplexing (FDM), the electronic device 101 may transmit a signal substantially simultaneously using the first RFFE 532 and the second RFFE 534. The electronic device 101 may reduce the maximum transmission power to reduce intermodulation distortion (IMD). The electronic device 101 may further reduce the maximum transmission power based on the number of resource blocks allocated to the electronic device 101 (e.g., the magnitude of radio frequency resource allocated to the electronic device 101). For example, when additional maximum power reduction (MPR) is applied, the electronic device 101 may further reduce the maximum transmission power, further using the MPR value and additional MPR factor ‘A’.
The electronic device 101 may determine the MPR value by subtracting a value, which is obtained by multiplying ‘A’ by a weight, from the specified MPR value. For example, the additional MPR factor ‘A’ may increase as the number of resource blocks allocated to the electronic device 101 increases. When the number of allocated resource blocks is relatively small, the MPR value may be relatively increased. For example, the MPR for a combination of the B41 band of the E-UTRAN and the n41 band of the NR may be shown in Table 1 below.
As shown in Table 1, the maximum transmission power may be reduced by up to 13 dBm. In this case, as the transmission power of the electronic device 101 is lowered, the error rate may be increased and the data throughput may be reduced. The electronic device 101 may change a transmission operating mode to improve transmitter linearity. The electronic device 101 may minimize the MPR by improving the transmitter linearity.
The processor (e.g., the first CP 512 in 601 of
In operation 805 of flowchart 800, the processor determines whether the number of uplink resource blocks is less than a threshold value. The processor may obtain information about the number of the uplink resource blocks allocated to the electronic device, from a base station. The processor may obtain the number of uplink resource blocks by receiving uplink resource information from the base station. The threshold value may be a value stored in a memory 130. The threshold value may be a value specified by a manufacturer, a user, and/or a network of the electronic device. The threshold value may be 5.
When the number of uplink resource blocks is not less than the threshold value, the processor maintains an operating mode of the power modulator, in operation 820. For example, the processor may maintain the operating mode of the power modulator in a first mode (e.g., ET-based power control mode) or a second mode (e.g., APT-based power control mode).
When the number of uplink resource blocks is less than the threshold value, the processor determines whether the operating mode of the power modulator is a second mode (e.g., the APT-based power control mode), in operation 810.
When the operating mode of the power modulator is the second mode, the processor maintains the operating mode of the power modulator as the second mode, in operation 820. When the operating mode of the power modulator is the first mode, the processor changes the operating mode of the power modulator to the second mode (e.g., the APT-based power control mode), in operation 815.
The processor (e.g., the first CP 512, and/or the second CP 514 of an electronic device 101 may perform the operations of
In operation 905 of flowchart 900, the processor determines whether the number of uplink resource blocks is less than a threshold value. Operation 905 may be similar to operation 805. When the number of uplink resource blocks is not less than the threshold value, the processor maintains an operating mode of the power modulator, in operation 925.
When the number of uplink resource blocks is less than to the threshold value, the processor determines whether the operating mode of the power modulator is a second mode (e.g., the APT-based power control mode), in operation 910.
When the operating mode of the power modulator is the second mode, the processor increases the output voltage (e.g., RFFE input voltage) of the power modulator, in operation 915. For example, the processor may add a DC offset voltage to the output voltage of the power modulator. For example, the DC offset voltage may be about 1 V.
When the operating mode of the power modulator is not the second mode (e.g., the operating mode of the power modulator is the first mode), the processor changes the operating mode of the power modulator to the second mode, in operation 920. In another example, the processor may change the operating mode of the power modulator to the second mode and may increase the output voltage of the power modulator (e.g., operation 915).
At least part of operations may be omitted from
In
As shown in Table 2, only the ET-based power supply control may not satisfy the MPR requirement of −25 dBm. The APT-based power control may not satisfy the MPR requirement of −25 dBm, but the difference from the MPR requirement may be relatively small at −3 dBm. The MPR value to be applied to the electronic device (e.g., to satisfy the MPR requirement) may be reduced by changing the power control method. In another example, when both APT-based power control and voltage addition are simultaneously applied to the power modulator, the electronic device may satisfy the MPR requirement without applying a separate MPR. The electronic device may improve transmission performance by reducing the MPR value. The electronic device may reduce the MPR value by improving the linearity of PA associated with the power modulator through control of the power modulator.
Referring again to
As shown in Table 3, the twofold multiplication number of band B3, the fourfold multiplication number of band B5, and the fourfold multiplication number of band B8 may overlap at least part of band N78. When the electronic device 101 transmits a signal in a band B3, B5, or B8 and simultaneously receives a signal using band N78, the sensitivity deterioration (e.g., desense) may occur in signal reception using band N78. For example, the electronic device 101 may perform backoff of LTE transmission power to reduce desense.
The frequency band available to the electronic device 101 may be set depending on the mobile network operator (MNO) of the region (e.g., country) where the electronic device 101 is located. When frequency bands may interfere with each other (e.g., generation combination of IMD or desense), the electronic device 101 may perform the above-described transmission power control and the backoff described later.
Channels (e.g., sub-frequency band) used by each MNO within a band may be different. For example, even when frequency bands interfere with each other (e.g., generation combination of IMD or desense), the electronic device 101 may perform the above-described transmission power control and the backoff described below, in consideration of the channel used by MNO. Even when frequency bands interfere with each other (e.g., generation combination of IMD or desense), the relationship between specific channels may not cause interference. When specific combinations of channels do not interfere with each other, the electronic device 101 may not perform the power backoff.
The processor (e.g., the first CP 512 and/or the second CP 514 of an electronic device 101 may perform the operations of
In operation 1005 of flowchart 1000, the processor obtains radio resource information. The processor may obtain the radio resource information from a network. The processor may obtain the radio resource information by receiving system information (e.g., system information block) of a base station associated (e.g., connected) with the electronic device. For example, the processor may obtain the radio resource information by obtaining band information included in system information of the base station. In another example, the processor may obtain the radio resource information, further using MNO information obtained from a public land mobile network identifier (PLMN ID) included in the system information of the base station.
In operation 1010, the processor determines whether the combination of the first band and the second band corresponds to the set band combination. The processor may determine whether the combination of the first band and the second band corresponds to the set band combination, by comparing the information stored in a memory with the received radio resource information. For example, the set band combination may be the combination of bands in each of which interference may be generated in the second band by a first band signal. The first band and the second band may be frequency bands of different RATs. In this case, the first band and the second band may be bands allocated to the electronic device according to MR-DC. In another example, the first band and the second band may be frequency bands of the same RAT. In this case, the first band and the second band may be bands set in the electronic device depending on the operation of carrier aggregation (CA) or dual connectivity.
When the combination of the first band and the second band corresponds to the configured band combination, the processor determines whether the combination of the first channel and the second channel corresponds to the set channel combination, in operation 1015. For example, the processor may obtain frequency band information of the first channel, using information about a network provider (e.g., MNO) associated with the first band of the obtained radio resource information. The processor may obtain frequency band information of the second channel of the second band, using the network provider information associated with the second band of the obtained radio resource information. Herein, a channel may mean a sub-frequency band used by the network provider for the corresponding band. When the combination of the first channel and the second channel causes mutual interference, the processor may determine that the first channel and the second channel correspond to the set channel combination. For example, the processor may obtain information of channel combinations (e.g., channel combinations capable of causing IMD or desense) from a memory. The information of channel combinations may include information of the channel combinations mapped in association with respective network provider information (e.g., MNO) and/or country information (e.g., mobile country code).
When the combination of the first band and the second band is not a combination capable of causing mutual interference, as determined in operation 1010, or when the combination of the first channel and the second channel is not a combination capable of causing mutual interference, as determined in operation 1015, the processor maintains the LTE transmission power depending, in operation 1025.
When the combination of channels allocated to the electronic device may cause mutual interference, the processor performs LTE power backoff, in operation 1020. In this case, the processor may reduce the transmission power associated with the transmission circuit of the first RFFE 532 of
Prior to operation 1010, the processor may determine whether to perform operations after operation 1010, based on the electric field state of the electronic device. For example, when the reference signal received power (RSRP) of the LTE network is less than a threshold value, the processor may maintain the LTE transmission power depending on operation 1025. The processor may prevent call drop in a weak electric field, by maintaining LTE transmission power. For another example, when the RSRP of the LTE network exceeds the threshold value, the processor may perform operation 1010.
The processor (e.g., the first CP 512 and/or the second CP 514 of an electronic device 101) may perform the operations of
In operation 1105 of flowchart 1100, the processor obtains radio resource information. Operation 1105 is similar to operation 1005 of
In operation 1110, the processor determines whether the combination of the first band and the second band corresponds to the set combination. Operation 1110 is similar to operation 1010 of
When the first band and the second band correspond to the set combination, the processor determines whether the combination of the first channel and the second channel corresponds to the set combination, in operation 1115. Operation 1115 is similar to operation 1015 of
When the combination of first channel and the second channel corresponds to the set channel combination, the processor determines whether the communication state is less than a threshold value, in operation 1120. When the RSRP of the LTE network is less than a threshold power or when the block error rate is not less than a threshold error rate, the processor may determine that the communication state is less than a threshold value. For example, when the communication state of the electronic device is a weak electric field, the processor may determine that the communication state is less than the threshold value.
When the communication state is not less than the threshold value, the processor limits LTE maximum transmission power and/or may control NR transmission power, in operation 1125. For example, the processor may reduce LTE-related maximum transmission power. In this case, the NR data reception throughput may be increased by reducing the desense for the NR band. In another example, the processor may increase NR-related transmission power. In this case, NR data reception throughput may be increased. In yet another example, the processor may reduce LTE-related maximum transmission power and may increase NR-related transmission power. For example, in the case of the combination of band B3 and band N78, the processor may limit the maximum transmission power in band B3 to 15 dBm and may increase the maximum transmission power in band N78 to 22 dBm. For example, in the case of band B5 and band N78, the processor may limit the maximum transmission power in band B5 to 18 dBm and may increase the maximum transmission power in band N78 to 21 dBm. For example, in the case of band B8 and band N78, the processor may limit the maximum transmission power in band B8 to 18 dBm and may increase the maximum transmission power in band N78 to 21 dBm.
When the communication state is less than the threshold value, the processor changes the operating mode of the power modulator and/or the LTE transmit antenna, in operation 1130. For example, the processor may change the operating mode of the power modulator to an operating mode (e.g., the second operating mode) capable of performing APT-based power control. In this case, the desense may be reduced due to the effect similar to the power backoff (e.g., power backoff of about 6 dBm). In another example, the processor may change an LTE transmission antenna to an antenna far from the NR reception antenna. For example, when the electronic device includes a plurality of LTE transmit antennas, the processor may reduce the interference to the NR band due to the LTE signal transmission by transmitting a signal using an LTE transmit antenna located physically far from the NR receive antenna. In another example, the processor may change the operating mode of the power modulator to an APT-based power control mode and may transmit an LTE signal, using an LTE antenna far from the NR receiving antenna.

The memory 1230 may store one or more instructions that, when executed, cause the processor 1290 to perform various operations.
The electronic device 1200 may use at least part of the housing 1201 as an antenna 1213 of the first wireless communication circuit 1210. For example, the first wireless communication circuit 1210 may use an upper portion 1301 and a lower portion 1302 of the housing 1201 as antennas.
The electronic device 1200 may use at least part of the housing 1201 as an antenna 1223 of the second wireless communication circuit 1220. For example, the second wireless communication circuit 1210 may use the upper-side portions 1311 and 1312 of the housing 1201 as transmission antennas and may use the lower-side portions 1313 and 1314 as reception antennas.
To prevent mutual interference between the first signal of the first wireless communication circuit 1210 and the second signal of the second wireless communication circuit 1220, the electronic device 1200 may transmit and receive signals, using a physically distant antenna. For example, the first wireless communication circuit 1210 and the second wireless communication circuit 1220 may simultaneously perform uplink transmissions. In this case, to reduce mutual interference, the electronic device 1200 may transmit signals using the upper-side portions 1311 and 1312 and the lower portion 1302 as antennas. In another example, the second wireless communication circuit 1220 may receive a signal while the first wireless communication circuit 1210 transmits a signal. In this case, to reduce mutual interference, the electronic device 1200 may transmit signals using the lower-side portions 1313 and 1314 and the upper portion 1301 as antennas.
The antenna configuration of
Hereinafter, various operations of the electronic device 1200 will be described based on the structure of the electronic device 1200 of
In operation 1405 of flowchart 1400, the processor 1290 obtains radio resource information. For example, the processor 1290 may obtain radio resource information from the connected base station 1299. The processor 1290 may obtain the radio resource information by receiving uplink resource information and/or system information block from the base station 1299. The radio resource information may include the number of uplink resource blocks allocated to the electronic device 1200 and/or information about a frequency band associated with a base station to which the electronic device 1200 is connected.
In operation 1410, the processor 1290 determines whether the combination of the first band and the second band corresponds to the set band combination. The first band is a frequency band in which the processor 1290 communicates with a network using the first wireless communication circuit 1210. The second band may be a frequency band in which the processor 1290 communicates with the network using the second wireless communication circuit 1220. The first band and the second band may be bands associated with a plurality of base stations to which the electronic device is connected. The first band and the second band may be a plurality of bands associated with the base station to which the electronic device is connected. The processor 1290 may determine whether the combination of the first band and the second band corresponds to the set band combination, by comparing the information of the frequency band combinations stored in the memory 1230 with the information of the first band and the second band indicated by the radio resource information. For example, the set band combination may be a combination in which the multiplication number of the first band overlaps with at least part of the second band. The set band combination may be a frequency band combination in which interference (e.g., IMD or desense) may occur between the first band and the second band. The set band combination may be a frequency band combination in which interference may occur among EN-DC band combinations configured to use FDD.
When the combination of the first band and the second band corresponds to the preset band combination, the processor 1290 determines whether the number of uplink resource blocks allocated to the electronic device 1200 is not less than a threshold value, in operation 1415. For example, the processor 1290 may obtain information about the number of allocated uplink resource blocks from radio resource information (e.g., uplink resource allocation information).
When the number of uplink resource blocks is not less than the threshold value, the processor 1290 controls the first power modulator 1212 and the second power modulator 1222 to be in a first mode (e.g., an ET-based power control mode), in operation 1420. Through ET-based power control, the processor 1290 may reduce power consumption of the electronic device 1200.
When the combination of the first band and the second band does not correspond to the preset band combination, as determined in operation 1410, or when the number of associated resource blocks is less than the threshold value, the processor 1290 controls the first power modulator 1212 and/or the second power modulator 1222 to be in a second mode (e.g., an APT-based power control mode), in operation 1425. Through power control based on APT, for example, the processor 1290 may reduce the amount of MPR associated with a wireless communication circuit (e.g., the first wireless communication circuit 1210 and/or the second wireless communication circuit 1220), thereby reducing degradation of communication quality. For example, as described above with respect to operation 915 of
In operation 1505 of flowchart 1500, the processor 1290 obtains radio resource information. Operation 1505 is similar to operation 1405 of
In operation 1510, the processor 1290 determines whether the combination of the first band and the second band corresponds to the set band combination. Operation 1510 is similar to operation 1410 of
When the combination of the first band and the second band corresponds to the set band combination, the processor 1290 determines whether the combination of the first channel of the first band and the second channel of the second band corresponds to the set channel combination, in operation 1515. The processor may determine whether the combination of the first channel and the second channel corresponds to the set channel combination. For example, the processor 1290 may obtain frequency band information of the first channel, using information about a network provider (e.g., MNO) associated with the first band of the obtained radio resource information (e.g., system information). The processor 1290 may obtain frequency band information of the second channel of the second band, using the network provider information associated with the second band of the obtained radio resource information. When the combination of the first channel and the second channel causes mutual interference, the processor 1290 may determine that the first channel and the second channel correspond to the set channel combination. For example, the processor 1290 may obtain information of channel combinations (e.g., channel combinations capable of causing IMD or Desense) from the memory 1230. The information of channel combinations may include information of the channel combinations mapped in association with respective network provider information (e.g., MNO) and/or country information (e.g., mobile country code).
When the combination of the first channel and the second channel corresponds to the set channel combination, the processor 1290 determines whether the number of resource blocks allocated to the electronic device 1200 is not less than a threshold value (e.g., five), in operation 1520. Operation 1520 is similar to operation 1415 of
When the number of resource blocks is not less than the threshold value, the processor 1290 determines whether the electric field is not less than the threshold value, in operation 1525. For example, the processor 1290 may identify an electric field based on RSRP received from the base station 1299. In this case, when the RSRP is less than a threshold power, the processor 1290 may determine that the electric field is less than the threshold value. In another example, the processor 1290 may identify the electric field based on the error rate of the data received from the base station 1299. In this case, when the error rate of the received data is not less than a threshold error rate, the processor 1290 may determine that the electric field is not less than a threshold value.
When the electric field is not less than the threshold value, the processor 1290 controls the second power modulator 1222 to be in a first mode (e.g., ET-based transmission power control), in operation 1530. For example, the processor 1290 may control the second power modulator 1222 to be in the first mode. In operation 1530, the processor 1290 may limit the maximum transmission power of the first wireless communication circuit 1210 (e.g., operation 1020 of
When the combination of bands does not correspond to the set band combination, as determined in operation 1510, when the combination of channels does not correspond to the set channel combination, as determined in operation 1515, when the number of resource blocks is less than the threshold value, as determined in operation 1520, or the electric field is less than a threshold value, as determined in operation 1525, the processor 1290 controls the second power modulator 1222 to be in the second mode (e.g., APT-based transmission power control), in operation 1535. The processor 1290 may control the first power modulator 1212 and the second power modulator to be in the second mode. For example, the processor 1290 may increase (e.g., add a DC offset) the output voltage of the first power modulator 1212 and/or the second power modulator 1222. The processor 1290 may transmit a signal, using an antenna physically located far from the antenna (e.g., a reception antenna used when the second wireless communication circuit 1220 receives a signal or a transmission antenna used when the second wireless communication circuit 1220 transmits a signal) associated with the second power modulator 1222 among the plurality of antennas associated with the first power modulator 1212.
According to an embodiment, an electronic device may include housing. The electronic device may include a first antenna and a second antenna, which are positioned inside the housing or form a portion of the housing. The electronic device may include a first power amplifier electrically connected to the first antenna and configured to transmit and/or receive a first signal having a frequency of 500 MHz and 6 GHz and a first wireless communication circuit including a first power modulator providing the first power amplifier with a voltage. The electronic device may include a second power amplifier electrically connected to the second antenna and configured to transmit and/or receive a second signal having a frequency of 500 MHz and 6 GHz and a second wireless communication circuit including a second power modulator providing the second power amplifier with a voltage. The electronic device may include, for example, at least one processor operatively connected to the first wireless communication circuit and the second wireless communication circuit and at least one memory operatively connected to the processor or coupled with the processor. The memory may store instructions that, when executed, cause the processor to receive information about a first transmission resource block associated with the first wireless communication circuit and/or a second transmission resource block associated with the second wireless communication circuit from a cellular base station through the first wireless communication circuit and/or the second wireless communication circuit while the first power modulator and/or the second power modulator uses ET, and to control the first power modulator and/or the second power modulator, using APT instead of the ET based at least partly on the received information.
The instructions may cause the processor to reduce the MPR value of at least one of the first wireless communication circuit or the second wireless communication circuit based at least partly on the received information, while satisfying MPR specification of 3GGP standard.
The memory may store instructions that, when executed, cause the processor to receive information about a first transmission resource block associated with the first wireless communication circuit and/or a second transmission resource block associated with the second wireless communication circuit from a cellular base station through the first wireless communication circuit and/or the second wireless communication circuit while the first power modulator and/or the second power modulator operate at the same time and at least one of the first power modulator and/or the second power modulator uses ET, and to change the voltage of the APT based at least partly on the received information.
The memory may store instructions that, when executed, cause the processor to check a lookup table associated with the interference between a frequency of the first signal and a frequency of the second signal when the strength of the second signal is less than a threshold, and to reduce power output through the second power amplifier by the selected magnitude based on the checked result.
The memory may store instructions that, when executed, cause the at least one processor to receive uplink resource information allocated to the electronic device from a base station via the first wireless communication circuit, and to cause at least one power modulator, from among the first power modulator and the second power modulator, to provide a voltage based on the APT, based on at least the number of uplink resource blocks indicated by the uplink resource information.
The one or more instructions may, when executed, cause the at least one processor to control the at least one power modulator to provide the voltage based on the APT, when the number of uplink resource blocks is less than a defined number. For example, the one or more instructions may, when executed, cause the at least one processor to add an offset voltage to an output voltage of at least one power modulator the first power modulator or the second power modulator, when the number of uplink resource blocks is less than the defined number.
For example, the first wireless communication circuit may be configured to transmit and/or receive a long term evolution (LTE)-based wireless signal; the second wireless communication circuit may be configured to transmit and/or receive a new radio (NR)-based wireless signal.
The one or more instructions may, when executed, cause the at least one processor to obtain information about a first frequency band associated with the first wireless communication circuit and information about a second frequency band associated with the second wireless communication circuit, and to control the at least one power modulator to provide the voltage based on the APT when a multiple of the first frequency band overlaps with at least part of the second frequency band.
The one or more instructions may, when executed, cause the at least one processor to obtain information about a first frequency band associated with the first wireless communication circuit and information about a second frequency band associated with the second wireless communication circuit, to determine whether a multiple of a first channel associated with the first wireless communication circuit in the first frequency band at least partially overlaps with a band of a second channel associated with the second wireless communication circuit in the second frequency band when a multiple of the first frequency band overlaps with at least part of the second frequency band, and to control the at least one power modulator to provide the power based on the APT when the multiple of the first channel at least partially overlaps with the band of the second channel.
For example, the one or more instructions may, when executed, cause the at least one processor to obtain first frequency band information of the first channel and frequency band information of the second channel, using first channel information of a first network provider associated with the first frequency band and second channel information of a second network provider associated with the second frequency band.
The one or more instructions may, when executed, cause the at least one processor to identify an electric field associated with the first wireless communication circuit when the number of uplink resource blocks is greater than or equal to a defined number, and to cause the second power modulator to provide a voltage based on the ET and to reduce a maximum transmission power of the first wireless communication circuit when the identified electric field is greater than or equal to a threshold value. For example, the one or more instructions may, when executed, cause the at least one processor to identify the electric field associated with the first wireless communication circuit when the number of uplink resource blocks is greater than or equal to than the defined number, and to control the first power modulator and the second power modulator to provide the voltage based on the APT when the identified electric field is less than the threshold value.
The one or more instructions may, when executed, cause the at least one processor to add an offset voltage to an output voltage of the second power modulator when the identified electric field is less than the threshold value.
