For example, each of the plurality of antennas may receive a signal from an external electronic device. For example, the signal received through the first antenna 191 may be provided to the RFIC 120 through the switch 111 and the switch 113. For example, in order to provide the signal to the RFIC 120, the processor 110 may control the switch 111 to connect a first terminal 111-1 to a second terminal 111-2 from among the second terminal 111-2 and a third terminal 111-3, and control the switch 113 to connect a third terminal 113-3 to a second terminal 113-2 from among a first terminal 113-1 and the second terminal 113-2.
For example, the RFIC 120 may include a receiving circuit including one or more receive (Rx) chains for the signal received through at least a portion of the plurality of antennas. For example, the signal received through the first antenna 191 may be provided to the receiving circuit through the LNA 122. For example, the receiving circuit may include a mixer for downward conversion, an analog to digital converter (ADC), and/or a PA (e.g., another PA distinct from the LNA 122). For example, the signal received through each of the second antenna 192 to the fourth antenna 194 (or the second antenna 192 to the fifth antenna 195) may be provided to the receiving circuit through another LNA (not shown in
For example, a signal received through at least a portion of the plurality of antennas may be processed within the RFIC 120 or may be processed using the receiving circuit. For example, the processed signal may be provided to the processor 110.
For example, the processor 110 may include various processing circuitry. For example, as used herein, including the claims, the term “processor” may include various processing circuitry, including at least one processor, wherein one or more of at least one processor may be configured to perform various functions described herein. Additionally, the at least one processor may include a combination of processors performing various of the recited/disclosed functions. At least one processor may execute program instructions to achieve or perform various functions. At least one processor 110 may execute a function corresponding to the signal, by processing the signal obtained from the RFIC 120.
For example, the processor 110 may generate or obtain a signal to be transmitted through at least a portion of the plurality of antennas. For example, the signal may be provided from the processor 110 to the RFIC 120.
For example, the processor 110 may control the switch 111, the switch 112, and/or the switch 113 for the transmission of the signal.
For example, in order to transmit the signal through the first antenna 191, the processor 110 may control the switch 113 to connect the third terminal 113-3 to the first terminal 113-1 from among the first terminal 113-1 and the second terminal 113-2. For example, in order to transmit the signal through the first antenna 191, the processor 110 may control the switch 111 to connect the first terminal 111-1 to the second terminal 111-2 from among the second terminal 111-2 and the third terminal 111-3.
For example, in order to transmit the signal through the second antenna 192, the processor 110 may control the switch 113 to connect the third terminal 113-3 to the first terminal 113-1 from among the first terminal 113-1 and the second terminal 113-2. For example, in order to transmit the signal through the second antenna 192, the processor 110 may control the switch 111 to connect the first terminal 111-1 to the third terminal 111-3 from among the second terminal 111-2 and the third terminal 111-3. For example, in order to transmit the signal through the second antenna 192, the processor 110 may control the switch 112 to connect the first terminal 112-1 to a second terminal 112-2 from among the second terminal 112-2, a third terminal 112-3, a fourth terminal 112-4, and a fifth terminal 112-5.
For example, in order to transmit the signal through the third antenna 193, the processor 110 may control the switch 113 to connect the third terminal 113-3 to the first terminal 113-1 from among the first terminal 113-1 and the second terminal 113-2. For example, in order to transmit the signal through the third antenna 193, the processor 110 may control the switch 111 to connect the first terminal 111-1 to the third terminal 111-3 from among the second terminal 111-2 and the third terminal 111-3. For example, in order to transmit the signal through the third antenna 193, the processor 110 may control the switch 112 to connect the first terminal 112-1 to the third terminal 112-3 from among the second terminal 112-2, the third terminal 112-3, the fourth terminal 112-4, and the fifth terminal 112-5.
For example, in order to transmit the signal through the fourth antenna 194, the processor 110 may control the switch 113 to connect the third terminal 113-3 to the first terminal 113-1 from among the first terminal 113-1 and the second terminal 113-2. For example, in order to transmit the signal through the fourth antenna 194, the processor 110 may control the switch 111 to connect the first terminal 111-1 to the third terminal 111-3 from among the second terminal 111-2 and the third terminal 111-3. For example, in order to transmit the signal through the fourth antenna 194, the processor 110 may control the switch 112 to connect the first terminal 112-1 to the fourth terminal 112-4 from among the second terminal 112-2, the third terminal 112-3, the fourth terminal 112-4, and the fifth terminal 112-5.
For example, when the fifth antenna 195 is included in the plurality of antennas, the processor 110 may control the switch 113 to connect the third terminal 113-3 to the first terminal 113-1 from among the first terminal 113-1 and the second terminal 113-2 in order to transmit the signal through the fifth antenna 195. For example, in order to transmit the signal through the fifth antenna 195, the processor 110 may control the switch 111 to connect the first terminal 111-1 to the third terminal 111-3 from among the second terminal 111-2 and the third terminal 111-3. For example, in order to transmit the signal through the fifth antenna 195, the processor 110 may control the switch 112 to connect the first terminal 112-1 to the fifth terminal 112-5 from among the second terminal 112-2, the third terminal 112-3, the fourth terminal 112-4, and the fifth terminal 112-5.
For example, the RFIC 120 may include a transmitting circuit including one or more transmit (Tx) chains for the signal to be transmitted through at least a portion of the plurality of antennas. Although not illustrated in
For example, the PA 121 may be used to obtain or set a Tx power of the signal (e.g., the signal processed within the RFIC 120) to be transmitted through an antenna (e.g., at least a portion of the plurality of antennas). For example, the signal may be transmitted through the first antenna 191 with the Tx power. For example, the signal may be transmitted through the second antenna 192 with the Tx power. For example, the signal may be transmitted through the third antenna 193 with the Tx power. For example, the signal may be transmitted through the fourth antenna 194 with the Tx power. For example, the signal may be transmitted through the fifth antenna 195 with the Tx power. As a non-limiting example, a power of the signal output from each of the first antenna 191 to the fifth antenna 195 may be different from the Tx power. For example, the power may vary according to a state of paths from the PA 121 to each of the first antenna 191 to the fifth antenna 195.
For example, the circuit 181 may be coupled with the first antenna 191 among the plurality of antennas. For example, the circuit 181 may be referred to as a coupler. For example, the circuit 181 may be used to obtain a coupling signal of the signal transmitted with the Tx power through the first antenna 191. For example, the coupling signal may be provided to the RFIC 120.
For example, the RFIC 120 may include a receiving circuit including one or more receive (Rx) chains for the coupling signal. For example, the receiving circuit may include a mixer for downward conversion, an analog to digital converter (ADC), and/or a PA. For example, the coupling signal processed within the RFIC 120 or processed using the receiving circuit may be provided to the processor 110.
For example, the processor 110 may identify a characteristic (or attribute) of the signal transmitted through the first antenna 191 based on the coupling signal. As a non-limiting example, the processor 110 may identify a difference between the power of the signal output from the first antenna 191 and the Tx power obtained using the PA 121, based on the coupling signal. For example, the processor 110 may identify a state related to the first antenna 191 used for transmission of the signal, based on the coupling signal. As a non-limiting example, the processor 110 may identify whether the first antenna 191 is covered (or in contact with an external object) by the external object (e.g., user's hand, and the like) based on the coupling signal.
For example, the circuit 181 may be coupled with the first antenna 191 from among the plurality of antennas, and may be disconnected from remaining antennas except for the first antenna 191 from among the plurality of antennas (e.g., the second antenna 192 to the fourth antenna 194 (or the second antenna 192 to the fifth antenna 195). For example, each of the remaining antennas may be disconnected from the circuit 181, and may not be coupled with a circuit for identifying a characteristic (and/or a state related to each of the remaining antennas) of a signal transmitted through each of the remaining antennas, such as the circuit 181. For example, unlike the first antenna 191, each of the remaining antennas may be mainly used for receiving a signal from an external electronic device. For example, each of the remaining antennas may be used for transmitting a sounding reference signal (SRS), but a main function of each of the remaining antennas may be reception. For example, since a main function of each of the remaining antennas is reception, the electronic device 100 may not include the circuit, which is coupled with each of the remaining antennas, such as the circuit 181 coupled with the first antenna 191. For example, the electronic device 100 may not include the circuit coupled with each of the remaining antennas, in order to enhance portability of the electronic device 100 (or miniaturize the electronic device 100). For example, since the electronic device 100 does not include the circuit, the processor 110 may not obtain a coupling signal of a signal transmitted through the second antenna 192, a coupling signal of a signal transmitted through the third antenna 193, and a coupling signal of a signal transmitted through the fourth antenna 194, via the RFIC 120. For example, when the electronic device 100 includes the fifth antenna 195, the processor 110 may not obtain a coupling signal of a signal transmitted through the fifth antenna 195 via the RFIC 120.
For example, since the processor 110 does not obtain a coupling signal of a signal transmitted through the second antenna 192, a coupling signal of a signal transmitted through the third antenna 193, and a coupling signal of a signal transmitted through the fourth antenna 194 via the RFIC 120, another signal, which is transmitted using the PA 121 through the first antenna 191 after a signal (e.g., a sounding reference signal (SRS)) is transmitted with the Tx power obtained using the PA 121 through each of the first antenna 191 to fourth antennas 194 may be degraded. For example, throughput of the other signal, which is transmitted through the first antenna 191 using the PA 121 after the signal is transmitted through each of the first antennas 191 to the fourth antennas 194, may be reduced. For example, a Tx power of the other signal, which is transmitted through the first antenna 191 using the PA 121 after the signal is transmitted through each of the first antennas 191 to the fourth antennas 194, may be smaller than a targeted Tx power. For example, reduction in the throughput of the other signal may be indicated as shown in Table 1.
In Table 1, the throughput of the other signal in Case 1 indicates throughput of the other signal transmitted through the first antenna 191 based on a coupling signal of the signal transmitted through each of the second antenna 192 to the fourth antenna 194, and the throughput of the other signal in Case 2 indicates throughput of the other signal transmitted through the first antenna 191 without use of the coupling signal of the signal transmitted through each of the first antennas 191 to the fourth antennas 194 as shown in
Unlike the electronic device 100, an electronic device to be illustrated below may include components for identifying a characteristic (or a state of each of the second antenna 192 to the fourth antenna 194 (or the second antenna 192 to the fifth antenna 195)) used for transmission of the above signals) of the signal transmitted through the remaining antennas (e.g., the second antenna 192 to the fourth antenna 194 (or the second antenna 192 to the fifth antenna 195)) for the throughput of the other signal.
For example, unlike the electronic device 100, the electronic device may include a circuit capable of being coupled with the second antenna 192 to the fourth antenna 194 (or the second antenna 192 to the fifth antenna 195). The electronic device including the circuit may be illustrated within the description of

For example, the processor 210 may generate or obtain a signal to be transmitted through at least a portion of the plurality of antennas. For example, the signal may be provided from the processor 210 to the RFIC 220. For example, the signal may include an SRS 241. For example, the signal may include a signal 242 that is distinct from the SRS 241 and includes control information and/or user data. For example, unlike the SRS 241, the signal 242 may be transmitted through a first antenna 291 from among the plurality of antennas. For example, the SRS 241 and/or the signal 242 may be provided from the processor 210 to the RFIC 220.

For example, the power may vary according to a state of paths from the PA 221 to each of the first antenna 291 to the fifth antenna 295.
For example, the processor 210 may control a switch 211, a switch 212, a switch 213, and/or a switch 214 for the transmission of the SRS 241.
For example, the processor 210 may control the switch 214 to connect a third terminal 214-3 to a first terminal 214-1 from among the first terminal 214-1 and a second terminal 214-2, for the SRS 241 transmitted through the first antenna 291.

For example, the processor 210 may transmit the SRS 241 through the first antenna 291 with a Tx power obtained using the PA 221 connected to the first circuitry 281 in accordance with the control of the switch 211.

For example, the signal 242 may be transmitted through the first antenna 291 after the SRS 241 is transmitted through the first antenna 291 to the fourth antenna 294 (or the first antenna 291 to the fifth antenna 295). For example, the processor 210 may control the switch 211 and the switch 214 for the transmission of the signal 242. For example, the processor 210 may control the switch 214 to connect the third terminal 214-3 to the first terminal 214-1 from among the first terminal 214-1 and the second terminal 214-2, in order to transmit the signal 242 through the first antenna 291.

For example, since the second coupling signal 252 to the fourth coupling signal 254 (or the second coupling signal 252 to the fifth coupling signal 255) partially share a path of the RFIC 220 with the first coupling signal 251, the electronic device 200 may provide a more efficient mounting space.
For example, since the electronic device 200 may identify a state of a wireless environment that changes while the SRS 241 is transmitted through each of the second antenna 292 to the fourth antenna 294 (or the second antenna 292 to the fifth antenna 295) based at least in part on the second coupling signal 252 to the fourth coupling signal 254 (or the second coupling signal 252 to the fifth coupling signal 255), the electronic device 200 may provide an enhanced communication service.
For example, since the electronic device 200 transmits the SRS 241 through each of the first antenna 291 to the fourth antenna 294 (or the first antenna 291 to the fifth antenna 295), the electronic device 200 may increase throughput of each of the signal 231 to the signal 234 (or the signal 231 to the signal 235).

For example, the electronic device may include a switch to form a path for obtaining a portion of the SRS 241 (e.g., a portion of power of the SRS 241) as the at least one other component. The at least one other component may be illustrated within the description of
