CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/KR2022/000389 designating the United States, filed on Jan. 10, 2022, in the Korean Intellectual Property Receiving Office and claiming priority to Korean Patent Application No. 10-2021-0004788, filed Jan. 13, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     Field 
     The disclosure relates to an electronic device and a method for controlling the power of a transmission signal in an electronic device including a plurality of antennas. 
     Description of Related Art 
     As mobile communication technology evolves, multi-functional portable terminals are commonplace and, to meet increasing demand for radio traffic, vigorous efforts are underway to develop 5G communication systems. To achieve a higher data transmission rate, 5G communication systems are being implemented on higher frequency bands (e.g., a band of 25 GHz to 60 GHz) as well as those used for 3G communication systems and long-term evolution (LTE) communication systems. 
     To mitigate pathloss on the mmWave band and increase the reach of radio waves, the following techniques are taken into account for the 5G communication system: beamforming, massive multi-input multi-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large scale antenna. 
     To transmit a signal from an electronic device to a communication network (e.g., a base station), data generated from a processor or a communication processor in the electronic device may be signal-processed through a radio frequency integrated circuit (RFIC) and radio frequency front-end (RFFE) circuit and then transmitted to the outside of the electronic device through at least one antenna. 
     The electronic device may provide a plurality of transmission paths (Tx paths) to transmit signals to a communication network (e.g., a base station). The plurality of transmission paths provided by the electronic device may include an RFIC and/or RFFE circuit for each path. 
     Further, each RFFE circuit may be connected with one or more antennas and, accordingly, the plurality of transmission paths may be divided into a plurality of antenna transmission paths (antenna Tx paths) corresponding to the one or more antennas. 
     In an LTE or 5G communication environment, to increase communication speed and provide high traffic, multi-radio access technology (RAT) interworking (e.g., E-UTRA new radio dual-connectivity (EN-DC) or carrier aggregation (CA) technology may be applied. The total radiation power (TRP) of the electronic device may be expressed as the sum of an antenna gain and the transmit power (Tx power) (e.g., conduction power). The electronic device may change the antenna gain by the antenna switch controller and change the transmit power by the transmit power controller, thereby changing the total radiation power of the electronic device. 
     For example, when the electronic device changes the antenna gain considering multiple frequency components, such as EN-DC or carrier aggregation, the transmit power controller may not identify the magnitude of the changed total radiation power, so that it may be difficult to additionally adjust the total radiation power. As the transmit power controller fails to reflect the change in the total radiation power, the communication performance of the electronic device may be degraded. 
     SUMMARY 
     Embodiments of the disclosure provide an electronic device capable of enhancing the communication performance of the electronic device by integratedly managing the state between the antenna gain and the transmit power in an environment in which two or more transmission signals (e.g., 2Tx) are transmitted, such as EN-DC or uplink CA (ULCA), and a method for controlling the power of a transmission signal in the electronic device. Embodiments of the disclosure provide an electronic device capable of enhancing the communication performance of the electronic device by transmitting a signal based on the transmit power set corresponding to an event related to an application processor or an event related to a communication processor and a method for controlling the power of a transmission signal in the electronic device. 
     According to various example embodiments, an electronic device may comprise: a memory, a communication processor, at least one radio frequency integrated circuit (RFIC) connected with the communication processor, and a plurality of antennas each connected with the at least one RFIC through at least one radio frequency front-end (RFFE) circuit or at least one antenna tuning circuit. The communication processor may be configured to: identify a change in an antenna-related setting for the plurality of antennas, identify frequency band information corresponding to a signal being communicated through at least one antenna among the plurality of antennas, in response to the change in the antenna-related setting, identify, from the memory, a transmit power-related setting value set corresponding to the identified frequency band information and an event related to the communication processor, and control the electronic device to adjust a power of a transmission signal to be transmitted through at least one antenna among the plurality of antennas, based on the identified transmit power-related setting value. 
     According to various example embodiments, a method for controlling a power of a transmission signal in an electronic device including a communication processor, at least one radio frequency integrated circuit (RFIC) connected with the communication processor, and a plurality of antennas each connected with the at least one RFIC through at least one radio frequency front-end (RFFE) circuit or at least one antenna tuning circuit may comprise: identifying a change in an antenna-related setting for the plurality of antennas, identifying frequency band information corresponding to a signal being communicated through at least one antenna among the plurality of antennas, in response to the change in the antenna-related setting, identifying, from a memory, a transmit power-related setting value set corresponding to the identified frequency band information and an event related to the communication processor, and adjusting a power of a transmission signal to be transmitted through at least one antenna among the plurality of antennas, based on the identified transmit power-related setting value. 
     According to various example embodiments, in an electronic device providing a plurality of antenna transmission paths, it is possible to compensate for the loss of transmit power which may occur in the structure or design of the electronic device by transmitting signals based on the transmit power set for each communication processor-related event or application processor-related event.

     The first communication processor  212  may include various processing circuitry and establish a communication channel of a band that is to be used for wireless communication with the first cellular network  292  or may support legacy network communication via the established communication channel According to various embodiments, the first cellular network may be a legacy network that includes second generation (2G), third generation (3G), fourth generation (4G), or long-term evolution (LTE) networks. The second communication processor  214  may include various processing circuitry and establish a communication channel corresponding to a designated band (e.g., from about 6 GHz to about 60 GHz) among bands that are to be used for wireless communication with the second cellular network  294  or may support fifth generation (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 rd generation partnership project (3GPP). Additionally, according to an embodiment, the first CP  212  or the second CP  214  may establish a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands that are to be used for wireless communication with the second cellular network  294  or may support fifth generation (5G) network communication via the established communication channel 
     The first communication processor  212  may perform data transmission/reception with the second communication processor  214 . For example, data classified as transmitted via the second cellular network  294  may be changed 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/receive data to/from the second communication processor  214  via an inter-processor interface  213 . The inter-processor interface  213  may be implemented as, e.g., universal asynchronous receiver/transmitter (UART) (e.g., high speed-UART (HS-UART)) or peripheral component interconnect bus express (PCIe) interface, but is not limited to a specific kind. The first communication processor  212  and the second communication processor  214  may exchange packet data information and control information using, e.g., a shared memory. The first communication processor  212  may transmit/receive various pieces of information, such as sensing information, output strength information, or resource block (RB) allocation information, to/from the second communication processor  214 . 
     According to implementation, the first communication processor  212  may not be directly connected with the second communication processor  214 . In this case, the first communication processor  212  may transmit/receive data to/from the second communication processor  214  via a processor  120  (e.g., an application processor). For example, the first communication processor  212  and the second communication processor  214  may transmit/receive data to/from the processor  120  (e.g., an application processor) via an HS-UART interface or PCIe interface, but the kind of the interface is not limited thereto. The first communication processor  212  and the second communication processor  214  may exchange control information and packet data information with the processor  120  (e.g., an application processor) using a shared memory. According to an embodiment, the first communication processor  212  and the second communication processor  214  may be implemented in a single chip or a single package. According to an embodiment, the first communication processor  212  or the second communication processor  214 , along with the processor  120 , an auxiliary processor  123 , or communication module  190 , may be formed in a single chip or single package. For example, as shown in  FIG. 2B , an integrated communication processor  260  may include various processing circuitry support all of the functions for communication with the first cellular network  292  and the second cellular network  294 . 
     Upon transmission, the first RFIC  222  may convert a baseband signal generated by the first communication processor  212  into a radio frequency (RF) signal with a frequency ranging from about 700 MHz to about 3 GHz which is used by the first cellular network  292  (e.g., a legacy network). Upon receipt, the RF signal may be obtained from the first network  292  (e.g., a legacy network) through an antenna (e.g., the first antenna module  242 ) and be pre-processed via an RFFE (e.g., the first RFFE  232 ). The first RFIC  222  may convert the pre-processed RF signal into a baseband signal that may be processed by the first communication processor  212 . Upon transmission, the second RFIC  224  may convert the baseband signal generated by the first communication processor  212  or the second communication processor  214  into a Sub6-band (e.g., about 6 GHz or less) RF signal (hereinafter, “5G Sub6 RF signal”) that is used by the second cellular network  294  (e.g., a 5G network). Upon receipt, the 5G Sub6 RF signal may be obtained from the second cellular network  294  (e.g., a 5G network) through an antenna (e.g., the second antenna module  244 ) and be pre-processed via an RFFE (e.g., the second RFFE  234 ). 
     The second RFIC  224  may convert the pre-processed 5G Sub6 RF signal into a baseband signal that may be processed by a corresponding processor of the first communication processor  212  and the second communication processor  214 . 
     The third RFIC  226  may convert the baseband signal generated by the second communication processor  214  into a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) RF signal (hereinafter, “5G Above6 RF signal”) that is to be used by the second cellular network  294  (e.g., a 5G network). Upon receipt, the 5G Above6 RF signal may be obtained from the second cellular network  294  (e.g., a 5G network) through an antenna (e.g., the antenna  248 ) and be pre-processed via the third RFFE  236 . The third RFIC  226  may convert the pre-processed 5G Above6 RF signal into a baseband signal that may be processed by the second communication processor  214 . According to an embodiment, the third RFFE  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 at least part of, the third RFIC  226 . In this case, the fourth RFIC  228  may convert the baseband signal generated by the second communication processor  214  into an intermediate frequency band (e.g., from about 9 GHz to about 11 GHz) RF signal (hereinafter, “IF signal”) and transfer the IF signal to the third RFIC  226 . The third RFIC  226  may convert the IF signal into a 5G Above6 RF signal. Upon receipt, the 5G Above6 RF signal may be received from the second cellular network  294  (e.g., a 5G network) through an antenna (e.g., the antenna  248 ) and be converted into an IF signal by the third RFIC  226 . The fourth RFIC  228  may convert the IF signal into a baseband signal that 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 single package. According to various embodiments, when the first RFIC  222  and the second RFIC  224  in  FIG. 2A or 2B  are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC is connected to the first RFFE  232  and the second RFFE  234  to convert a baseband signal into a signal of a band supported by the first RFFE  232  and/or the second RFFE  234 , and may transmit the converted signal to one of the first RFFE  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 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 be combined with another antenna module to process multi-band RF signals. 
     According to an embodiment, the third RFIC  226  and the antenna  248  may be disposed on the same substrate to form the third antenna module  246 . For example, the wireless communication module  192  or the processor  120  may be disposed on a first substrate (e.g., a main painted circuit board (PCB)). In this case, the third RFIC  226  and the antenna  248 , respectively, may be disposed on one area (e.g., the bottom) and another (e.g., the top) of a second substrate (e.g., a sub PCB) which is provided separately from the first substrate, forming the third antenna module  246 . Placing the third RFIC  226  and the antenna  248  on the same substrate may shorten the length of the transmission line therebetween. This may reduce a loss (e.g., attenuation) of high-frequency band (e.g., from about 6 GHz to about 60 GHz) signal used for 5G network communication due to the transmission line. Thus, the electronic device  101  may enhance the communication quality with the second network  294  (e.g., a 5G network). According to an embodiment, the antenna  248  may be formed as an antenna array which includes a plurality of antenna elements available for beamforming. In this case, 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 . Upon transmission, the plurality of phase shifters  238  may change the phase of the 5G Above6 RF signal which is to be transmitted to the outside (e.g., a 5G network base station) of the electronic device  101  via their respective corresponding antenna elements. Upon receipt, the plurality of phase shifters  238  may change the phase of the 5G Above6 RF signal received from the outside to the same or substantially the same phase via their respective corresponding antenna elements. This enables transmission or reception via beamforming between the electronic device  101  and the outside. The second cellular network  294  (e.g., a 5G network) may be operated independently (e.g., as standalone (SA)) from, or in connection (e.g., as non-standalone (NSA)) with the first cellular network  292  (e.g., a legacy network). For example, the 5G network may include access networks (e.g., 5G access networks (RANs)) but lack any core network (e.g., a next-generation core (NGC)). In this case, the electronic device  101 , after accessing a 5G network access network, may access an external network (e.g., the Internet) under the control of the core network (e.g., the evolved packet 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  230  and be accessed by other components (e.g., the processor  120 , the first communication processor  212 , or the second communication processor  214 ).

The 5G network may include, e.g., a new radio (NR) base station  350  (e.g., a gNodeB (gNB)) that supports radio access with the electronic device  101  and a 5th generation core (5GC)  352  that manages 5G communication for the electronic device  101 . According to an embodiment, the electronic device  101  may transmit or receive control messages and user data via legacy communication and/or 5G communication. The control messages may include, e.g., messages related to at least one of security control, bearer setup, authentication, registration, or mobility management for the electronic device  101 . The user data may refer to, e.g., user data except for control messages transmitted or received between the electronic device  101  and the core network  330  (e.g., the EPC  342 ). 
     Referring to  FIG. 3A , according to an embodiment, the electronic device  101  may transmit or receive at least one of a control message or user data to/from at least part (e.g., the NR base station  350  or 5GC  352 ) of the 5G network via at least part (e.g., the LTE base station  340  or EPC  342 ) of the legacy network. According to various embodiments, the network environment  300   a  may include a network environment that provides wireless communication dual connectivity (DC) to the LTE base station  340  and the NR base station  350  and transmits or receives control messages to/from the electronic device  101  via one core network  230  of the EPC  342  or the 5GC  352 . 
     According to various embodiments, in the DC environment, one of the LTE base station  340  or the NR base station  350  may operate as a master node (MN)  310 , and the other as a secondary node (SN)  320 . The MN  310  may be connected with the core network  230  to transmit or receive control messages. The MN  310  and the SN  320  may be connected with each other via a network interface to transmit or receive messages related to radio resource (e.g., communication channel) management therebetween. 
     According to an embodiment, the MN  310  may include the LTE base station  340 , the SN  320  may include the NR base station  350 , and the core network  330  may include the EPC  342 . For example, control messages may be transmitted/received via the LTE base station  340  and the EPC  342 , and user data may be transmitted/received via at least one of the LTE base station  340  or the NR base station  350 . 
     According to an embodiment, the MN  310  may include the NR base station  350 , and the SN  320  may include the LTE base station  340 , and the core network  330  may include the 5GC  352 . For example, control messages may be transmitted/received via the NR base station  350  and the 5GC  352 , and user data may be transmitted/received via at least one of the LTE base station  340  or the NR base station  350 . Referring to  FIG. 3B , according to an embodiment, the 5G network may include the NR base station  350  and the 5GC  352  and transmit or receive control messages and user data independently from the electronic device  101 . 
     Referring to  FIG. 3C , according to an embodiment, the legacy network and the 5G network each may provide data transmission/reception independently. For example, the electronic device  101  and the EPC  342  may transmit or receive control messages and user data via the LTE base station  340 . As another example, the electronic device  101  and the 5GC  352  may transmit or receive control messages and user data via the NR base station  350 . 
     According to various embodiments, the electronic device  101  may be registered in at least one of the EPC  342  or the 5GC  352  to transmit or receive control messages. According to various embodiments, the EPC  342  or the 5GC  352  may interwork with each other to manage communication for the electronic device  101 . For example, mobility information for the electronic device  101  may be transmitted or received via the interface between the EPC  342  and the 5GC  352 . 
     As set forth above, dual connectivity via the LTE base station  340  and the NR base station  350  may be referred to as E-UTRA new radio dual connectivity (EN-DC). 
     Hereinafter, referring to  FIGS. 4A, 4B, 4C, 4D, 4E, 5A, 5B, 5C, 5D, 6, and 7 , the structure and operation of the electronic device  101  according to various embodiments are described in greater detail. Although each drawing of the embodiments described below illustrates that one communication processor  260  and one RFIC  410  are connected to a plurality of RFFEs  431 ,  432 ,  433 , and  611  to  640 , various embodiments described below are not limited thereto. For example, in various embodiments described below, as illustrated in  FIG. 2A  or  FIG. 2B , a plurality of communication processors  212  and  214  and/or a plurality of RFICs  222 ,  224 ,  226 , and  228  may be connected to a plurality of RFFEs  431 ,  432 ,  433 , and  611  to  640 . 
       FIGS. 4A, 4B, 4C, 4D, and 4E  are block diagrams illustrating example configurations of an electronic device according to various embodiments. 
     According to various embodiments,  FIG. 4A  illustrates an embodiment in which the electronic device  101  includes two antennas  441  and  442  and switches a transmission path, and  FIG. 4B  illustrates an embodiment in which the electronic device  101  includes three antennas  441 ,  442 , and  443  and switches a transmission path. 
     Referring to  FIG. 4A , according to various embodiments, an electronic device (e.g., the electronic device  101  of  FIG. 1 ) may include a processor (e.g., including processing circuitry)  120 , a communication processor (e.g., including processing circuitry)  260 , an RFIC  410 , a first RFFE  431 , a second RFEE  432 , a first antenna  441 , a second antenna  442 , a switch  450 , a first antenna tuning circuit  441   a , and/or a second antenna tuning circuit  442   a . For example, the first RFFE,  431  may be disposed at an upper end in the housing of the electronic device  101 , and the second RFFE  432  may be disposed at a lower end in the housing of the electronic device  101 . However, various embodiments are not limited to the placement positions. 
     According to various embodiments, upon transmission, the RFIC  410  may convert a baseband signal generated by the communication processor  260  into a radio frequency (RF) signal used in the communication network. For example, the RFIC  410  may transmit an RF signal used in the first communication network to the first antenna  441  or the second antenna  442  through the first RFFE  431  and the switch  450 . 
     According to various embodiments, the transmission path of transmission from the RFIC  410  to the first antenna  441  through the first RFFE  431  and the switch  450  may be referred to as a ‘first antenna transmission path (Ant Tx  1 )’. The transmission path of transmission from the RFIC  410  to the second antenna  442  through the first RFFE  431  and the switch  450  may be referred to as a ‘second antenna transmission path (Ant Tx  2 )’. According to various embodiments, different path loss may occur in the two antenna transmission paths because the lengths of the transmission paths and/or components disposed on the transmission paths are different from each other. Further, as the antennas (e.g., the first antenna  441  and the second antenna  442 ) corresponding to each separate antenna transmission path are disposed in different positions on the electronic device  101 , different antenna losses may occur. 
     According to various embodiments, the first antenna tuning circuit  441 a may be connected with the front end of the first antenna  441 , and the second antenna tuning circuit  442 a may be connected to the front end of the second antenna  442 . The communication processor  260  may adjust the setting value of the first antenna tuning circuit  441 a and the setting value of the second antenna tuning circuit  442   a  to adjust (e.g., tuning) the characteristics of the signal (e.g., transmission signal Tx) transmitted through each connected antenna and the signal (e.g., reception signal Rx) received through each connected antenna. Detailed embodiments thereof are described below with reference to  FIGS. 5A, 5B, 5C, and 5D . 
     According to various embodiments, the communication processor  260  may control the switch  450  to set the first RFFE  431  to be connected with the first antenna tuning circuit  441 a and the first antenna  441 . In this case, the transmission signal Tx generated by the communication processor  260  may be transmitted through the RFIC  410 , the first RFFE  431 , the switch  450 , the first antenna tuning circuit  441   a , and the first antenna  441 . 
     According to various embodiments, the first antenna  441  may be set as a primary reception (Rx) (PRx) antenna, and the second antenna  442  may be set as a diversity reception (Rx) (Drx) antenna. The electronic device  101  may receive and decode the signal transmitted from the base station through the first antenna  441  and/or the second antenna  442 . For example, the signal received through the first antenna  441 , as a PRx signal, may be transmitted to the communication processor  260  through the first antenna tuning circuit  441   a , the switch  450 , the first RFFE  431 , and the RFIC  410 . Further, the signal received through the second antenna  442 , as a DRx signal, may be transmitted to the communication processor  260  through the second antenna tuning circuit  442   a , the switch  450 , the second RFFE  432 , and the RFIC  410 . According to various embodiments, the first RFFE  431  may include at least one duplexer or at least one diplexer to process the transmission signal Tx and the reception signal PRx together. The second RFFE  432  may include at least one duplexer or at least one diplexer to process the transmission signal Tx and the reception signal DRx together. 
     According to various embodiments, the communication processor  260  may control the switch  450  to set the first RFFE  431  to be connected with the second antenna tuning circuit  442   a  and the second antenna  442 . In this case, the transmission signal Tx generated by the communication processor  260  may be transmitted through the RFIC  410 , the first RFFE  431 , the switch  450 , the second antenna tuning circuit  442   a , and the second antenna  442 . 
     According to various embodiments, when the first RFFE  431  is set to be connected with the second antenna tuning circuit  442   a  and the second antenna  442  as described above, the second antenna  441  may be set as a primary reception (Rx) antenna (PRx), and the first antenna  442  may be set as a diversity Rx antenna (DRx). The electronic device  101  may receive and decode the signal transmitted from the base station through the first antenna  441  and the second antenna  442 . For example, the signal received through the second antenna  441 , as a PRx signal, may be transmitted to the communication processor  260  through the second antenna tuning circuit  442   a , the switch  450 , the first RFFE  431 , and the RFIC  410 . Further, the signal received through the first antenna  442 , as a DRx signal, may be transmitted to the communication processor  260  through the first antenna tuning circuit  441   a , the switch  450 , the second RFFE  432 , and the RFIC  410 . 
     According to various embodiments, the communication processor  260  may set or change (e.g., switch) an antenna for transmitting the transmission signal Tx by controlling the switch  450  according to various setting conditions. According to various embodiments, the communication processor  260  may set a transmission path corresponding to an antenna capable of radiating the transmission signal Tx in the maximum power. For example, if a transmission signal is transmitted by the electronic device  101  including a plurality of antenna transmission paths as illustrated in  FIG. 4A , an optimal antenna transmission path may be set considering the channel environment (e.g., the strength of the reception signal) corresponding to each antenna (e.g., the first antenna  441  and the second antenna  442 ) and the maximum transmittable power. The communication processor  260  may determine an optimal antenna transmission path and may control the switch  450  so that a transmission signal is transmitted through the determined optimal antenna transmission path. 
     According to various embodiments, the electronic device  101  (e.g., the communication processor  260 ) may identify (or identify whether to switch antennas) whether to change the transmission paths of the transmission signal at each set time period (e.g., 640 ms) or when a specific event occurs (e.g., when an SAR event occurs or the electric field situation drastically changes, or upon base station signaling, EN-DC operation, or CA operation). 
       FIG. 18  is a block diagram illustrating an example method for determining maximum transmittable power according to various embodiments. Referring to  FIG. 18 , according to various embodiments, the maximum transmittable power for each transmission path may be set considering at least one of the maximum transmittable power (P-MAX power (PeMax) received from each communication network (e.g., a base station), the maximum transmittable power (UE Tx MAX power (PcMax) for each transmission path set by the electronic device  101 , or an SAR event maximum transmittable power (SAR EVENT MAX power) set corresponding to each SAR event considering the specific absorption rate (SAR) backoff. For example, the maximum transmittable power may be determined as a minimum value among the plurality of the above example maximum transmittable powers (e.g., P-MAX power, UE Tx MAX power, and SAR EVENT MAX power), but is not limited thereto. According to various embodiments, the maximum transmittable power of the SAR event may be set to differ according to each SAR event (e.g., a grip event or a proximity event). Hereinafter, an example of determining the maximum transmittable power for each transmission path based on the plurality of maximum transmittable powers exemplified above is described in detail. 
     According to various embodiments, the maximum transmittable power (P-MAX power) (PeMax) received from the communication network (e.g., a base station) may be set to differ according to the power class (PC) supportable by each communication network or electronic device. For example, when the power class is PC 2 , it may be determined as a value (e.g., 27 dBm) within a range set with respect to 26 dBm, and it may be determined as a value (e.g., 24 dBm) within a range set with respect to 23 dBm when the power class is PC 3 . 
     According to various embodiments, the maximum transmittable power (UE Tx MAX power, PcMax) for each transmission path set in the electronic device  101  may differ as the RFFE, for each transmission path is different, and it may also differ as the length of each transmission path is different. Hereinafter, an example in which the maximum transmittable power (UE Tx MAX power, PcMax) for each transmission path set in the electronic device  101  is different for each transmission path is described with reference to  FIG. 4E . 
       FIG. 4E  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. Referring to  FIG. 4E , according to various embodiments, the electronic device  101  may support communication with a plurality of communication networks. For example, the electronic device  101  may support a first communication network and a second communication network. The first communication network and the second communication network may be different communication networks. For example, the first communication network may be a 5G network, and the second communication network may be a legacy network (e.g., an LTE network). When the first communication network is a 5G network, the first RFFE  431  may be designed to be suitable for processing signals corresponding to the 5G network, and the second RFFE  432  may be designed to be suitable for processing signals corresponding to the legacy network. 
     According to various embodiments, a frequency band of a signal transmitted through the first RFFE  431  and a frequency band of a signal transmitted through the second RFFE  432  may be the same, similar, or different. For example, the frequency band of the signal transmitted through the first RFFE  431  may be an N41 band (2.6 GHz), which is a frequency band of a 5G network, and the frequency band of the signal transmitted through the second RFFE  432  may be a B41 band (2.6 GHz), which is a frequency band of an LTE network. In this case, the first RFFE  431  and the second RFFE  432  process the same or similar frequency band signals, but the first RFFE,  431  may be designed to enable signal processing suitable for the characteristics of the 5G network, and the second RFFE  432  may be designed to enable signal processing suitable for the characteristics of the LTE network. 
     According to various embodiments, the first RFFE  431  may be designed to process a signal of a wider frequency bandwidth than the second RFFE  432 . For example, the first RFFE  431  may be designed to process up to a frequency bandwidth of 100 MHz, and the second RFFE  432  may be designed to process up to a frequency bandwidth of 60 MHz. 
     According to various embodiments, the first RFFE  431  may include additional components (e.g., a single pole double throw (SPDT) switch for transmitting sounding reference signals (SRSs), a filter to prevent and/or reduce interference between the 5G signal and the WIFI signal of similar bands, a component to separate the WIFI signal from the reception signal, and a duplexer to separate different 5G band signals) different from the second RFFE  432  for multi-band support or for signal processing appropriate for the characteristics of 5G network. Referring to  FIG. 4E , the first RFFE  431  may include a front end module (FEM)  460  and a first SPDT switch  470 . According to various embodiments, the FEM  460  may include a power amplifier (PA)  461 , a switch  462 , and a filter  463 . According to various embodiments, the 1-BM  460  may be connected with a PA envelop tracking (ET) IC  464  to amplify power according to the amplitude of the signal, thereby reducing current consumption and heat generation and enhancing the performance of the PA  461 . 
     According to various embodiments, the first SPDT switch  470  may selectively output the first communication network signal (e.g., N41 band signal) and the sounding reference signal (SRS) (e.g., N41 band SRS signal) transmitted through the FEM  460  from the RFIC  410  and transmit it through the first antenna  441 . For example, the attenuation (e.g., path loss) caused according to the processing of the transmission signal by the components added for 5G signal processing or multi-band signal processing configured inside the first RFFE  431  and the first SPDT switch  470  for SRS transmission may increase over that in the second RFFE  432 . For example, although each of the power amplifier of the first RFFE  431  and the power amplifier of the second RFFE  432  is controlled to transmit the same power of signal by the communication processor  260 , since the path loss of the first RFFE  431  is larger than the path loss of the second 
     RFFE  432 , the magnitude of the signal transmitted through the first antenna module  441  may be smaller than the magnitude of the signal transmitted through the second antenna module  442 . 
     Referring to Table 1, as each transmission path differs in the same N41 band (or B41 band), the maximum power may differ for each transmission path.

     Referring to Table 1, it may be seen that the path loss for the upper N41 path transmitted through the first RFFE  431  is larger than the path loss for the lower N41 path transmitted through the second RFFE  432  by 2 dB or more. 
     Referring back to  FIG. 4A , according to various embodiments, even when the same magnitude of signal is transmitted from the first RFFE  431 , the power actually radiated from the first antenna  441  through the switch  450  and the power actually radiated from the second antenna  442  through the switch  450  may be different from each other. Further, for the maximum transmittable power transmitted from the electronic device  410 , the maximum transmittable power when a signal is transmitted through the first RFFE  431  to the first antenna  441 , the maximum transmittable power transmitted when a signal is transmitted to the second antenna  442  through the first RFFE  431 , the maximum transmittable power when a signal is transmitted through the second RFFE  432  to the first antenna  441 , and the maximum transmittable power when a signal is transmitted through the second RFFE  432  to the second antenna  442  may differ from each other. 
     According to various embodiments, when the first communication network performs transmission/reception of the N41 band signal of the 5G network, the first RFFE  431  may be designed to be appropriate for processing the signal corresponding to the 5G network, and the second RFFE  432  may be designed to be appropriate for processing the mid/high-band LTE signal (e.g., B2 or B41 band signal). At least one of the first RFFE  431  and the second RFFE  432  may be configured in the form of a power amplitude module including duplexer (PAMiD). 
     According to various embodiments, a frequency band of a signal transmitted through the first RFFE  431  and a frequency band of a signal transmitted through the second RFFE  432  may be the same, similar, or different. For example, the frequency band of the signal transmitted through the first RFFE  431  may be an N41 band (2.6 GHz), which is a high-band frequency of a 5G network, and the frequency band of the signal transmitted through the second RFFE  432  may be a B41 band (2.6 GHz), which is a high-band frequency of an LTE network. In this case, the first RFFE  431  and the second RFFE  432  process the same or similar frequency band signals, but the first RFFE  431  may be designed to enable signal processing suitable for the characteristics of the 5G network, and the second RFFE  432  may be designed to enable signal processing suitable for the characteristics of the LTE network. 
     According to an embodiment, the frequency band of the signal transmitted through the first RFFE  431  may be an N41 band (2.6 GHz), which is a high-band frequency of a 5G network, and the frequency band of the signal transmitted through the second RFFE  432  may be a B2 band (1.9 GHz), which is a mid-band frequency of an LTE network. 
     According to various embodiments, as the second RFFE  432  is designed to be suitable for processing mid/high-band LTE signals (e.g., B2 or B41 band signals), the first RFFE  431  and the electronic device  101  may operate in various types of EN-DC. For example, the first RFFE  431  and the second RFFE  432  may be combined to operate as EN-DC of B2-N41 and they may also operate as EN-DC of B41-N41. 
     According to various embodiments, the maximum transmittable power (UE Tx MAX power) for each transmission path set in the electronic device  101  may be set further considering a predefined maximum power reduction (MPR) or additional maximum power reduction (A-MPR) as shown in Table 2 and Table 3 below.

     Referring to Table 2 and Table 3, the maximum transmit power of each antenna transmission path may be set to differ according to a difference in path loss. Table 2 and Table 3 show the MPRs defined according to the 3GPP standard. Table 2 shows the MPR for power class (PC)  3 , and Table 3 shows the MPR for power class  2 . According to various embodiments, the MPR backoff may vary according to the modulation type or bandwidth (BW) even in the same channel environment. According to various embodiments, when the electronic device  101  receives the power class, as power class  3  of Table 2, from the base station, the maximum power of the first transmission path (e.g., the upper N41 transmission path of the electronic device  101 ) and the second transmission path (e.g., the lower N41 transmission path of the electronic device  101 ) may be determined to differ as shown in Table 4 below.

     Referring to Table 4 above, e.g., even in a state in which the maximum transmit power (P-MAX power) received by the electronic device  101  from the base station is the same as 24 dBm corresponding to PC 3 , if the path loss described in connection with Table 1 and the MPR backoff described in connection with Tables 2 and 3 are applied, the maximum transmittable power for each transmission path may be set to differ according to each modulation type or bandwidth. 
     For example, the maximum transmittable power for the upper N41 transmission path (first transmission path) in Table 4 may be identified as 24 dBm, which is the minimum value as illustrated in  FIG. 8 , if the maximum transmit power set in the electronic device considering the path loss of Table 1 is 24.5 dBm, and the maximum transmit power corresponding to PC 3 , which is received from the base station, is 24 dBm. In this case, if the minimum values of P-MAX Power and UE Tx MAX Power are calculated by applying the MPR backoff of Table 2 and Table 3 to UE Tx MAX Power, 22.5 dBm, 21.5 dBm, 21 dBm, and 18 dBm may be identified in CP OFDM Inner 16 QAM, CP OFDM Outer 16 QAM, CP OFDM 64 QAM, and CP OFDM 256 QAM, respectively, as shown in Table 4. 
     Further, the maximum transmittable power for the lower N41 transmission path (second transmission path) in Table 4 may be identified as 24 dBm, which is the minimum value as illustrated in  FIG. 8 , if the maximum transmit power set in the electronic device considering the path loss of Table 1 is 27 dBm, and the maximum transmit power corresponding to PC 3 , which is received from the base station, is 24 dBm. In this case, if the minimum values of P-MAX Power and UE Tx MAX Power are calculated by applying the MPR backoff of Table 2 and Table 3 to UE Tx MAX Power, 24 dBm, 24 dBm, 23.5 dBm, and 20.5 dBm may be identified in CP OFDM Inner 16 QAM, CP OFDM Outer 16 QAM, CP OFDM 64QAM, and CP OFDM 256 QAM, respectively, as shown in Table 4. 
     Referring to Table 4, as the application of the MPR is varied depending on the modulation scheme or bandwidth so that the UE Tx MAX Power is varied, the difference in the maximum transmittable power for each transmission path finally calculated according to  FIG. 8  may be shown as different. For example, the maximum transmittable power for each transmission path may differ by 1.5 dB in CP OFDM Inner 16 QAM, by 2.5 dB in CP OFDM Outer 16 QAM, by 1.5 dB in CP OFDM 64 QAM, and by 1.5 dB in CP OFDM 256 QAM. 
     According to various embodiments, upon determining the maximum transmittable power, the SAR event maximum transmittable power set considering the SAR backoff may be further considered. For example, referring to Table 5 below, if SAR backoff is applied according to the SAR event for each type, the maximum transmittable power for each path may vary. For example, if a SAR event, such as a grip event or a proximity event, is detected by the sensor, the electronic device  101  may apply the SAR backoff corresponding to each SAR event to the maximum transmittable power.

     Referring to Table 5, if a proximity event occurs, the SAR backoff for the proximity event is applied to the upper N41 transmission path (first transmission path) so that the maximum transmittable power may be determined as 19 dBm and, if a grip event occurs, the SAR backoff for the grip event is applied to the lower N41 transmission path (second transmission path) so that the maximum transmittable power may be determined as  2  ldBm. For example, the grip event may be detected by a touch sensor when the user grips the electronic device  101  in her hand, and the proximity event may be detected by the proximity sensor when the user approaches the electronic device  101  for a phone call. The event detection result by each sensor may be transferred to the communication processor  260  through the processor  120 . 
     Hereinafter, an electronic device according to various embodiments is described with reference to  FIGS. 4B, 4C, and 4D . In the embodiments described below, since the methods for determining the transmission path described above with reference to  FIG. 4A  may be applied in the same or similar manner, the overlapping description will be omitted.  FIG. 4B  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. 
     Referring to  FIG. 4B , according to various embodiments, an electronic device (e.g., the electronic device  101  of  FIG. 1 ) may include a processor (e.g., including processing circuitry)  120 , a communication processor (e.g., including processing circuitry)  260 , an RFIC  410 , a first RFFE,  431 , a second RFFE  432 , a first antenna  441 , a second antenna  442 , a third antenna  443 , a switch  450 , a first antenna tuning circuit  441   a , a second antenna tuning circuit  442   a , and/or a third antenna tuning circuit  443 a. For example, the first RFFE  431  may be disposed at an upper end in the housing of the electronic device  101 , and the second RFFE  432  may be disposed at a lower end in the housing of the electronic device  101 . However, various embodiments of the disclosure are not limited to the placement positions. 
     According to various embodiments, upon transmission, the RFIC  410  may convert a baseband signal generated by the communication processor  260  into a radio frequency (RF) signal used in the communication network. For example, the RFIC  410  may transmit an RF signal used in the first communication network to the first antenna  441  or the second antenna  442  through the first RFFE  431  and the switch  450 . 
     According to various embodiments, the transmission path of transmission from the RFIC  410  to the first antenna  441  through the first RFFE  431  and the switch  450  may be referred to as a ‘first antenna transmission path (Ant Tx  1 )’. The transmission path of transmission from the 
     RFIC  410  to the second antenna  442  through the first RFFE  431  and the switch  450  may be referred to as a ‘second antenna transmission path (Ant Tx  2 )’. According to various embodiments, different path loss may occur in the two antenna transmission paths because the lengths of the transmission paths and components disposed on the transmission paths are different from each other. Further, as the antennas (e.g., the first antenna  441  and the second antenna  442 ) corresponding to each separate antenna transmission path are disposed in different positions on the electronic device  101 , different antenna losses may occur. Further, the first antenna tuning circuit  441 a may be connected with the front end of the first antenna  441 , and the second antenna tuning circuit  442   a  may be connected to the front end of the second antenna  442 . The communication processor  260  may adjust the setting value of the first antenna tuning circuit  441 a and the setting value of the second antenna tuning circuit  442   a  to tune the signal (e.g., transmission signal Tx) transmitted through each connected antenna and the signal (e.g., reception signal Rx) received through each connected antenna. A detailed description thereof is given in greater detail below with reference to  FIGS. 5A, 5B, 5C, and 5D . 
     According to various embodiments, the communication processor  260  may control the switch  450  to set the first RFFE  431  to be connected with the first antenna tuning circuit  441   a  and the first antenna  441 . In this case, the transmission signal Tx generated by the communication processor  260  may be transmitted through the RFIC  410 , the first RFFE  431 , the switch  450 , the first antenna tuning circuit  441   a , and the first antenna  441 . 
     According to various embodiments, the first antenna  441  may be set as a primary reception (Rx) (PRx) antenna, and the third antenna  443  may be set as a diversity Rx (Drx) antenna. The electronic device  101  may receive and decode the signal transmitted from the base station through the first antenna  441  and the third antenna  443 .

Further, the signal received through the third antenna  443 , as a DRx signal, may be transmitted to the communication processor  260  through the third antenna tuning circuit  443   a , the second RFFE  432 , and the RFIC  410 .

The electronic device  101  may receive and decode the signal transmitted from the base station through the second antenna  442  and the third antenna  443 . For example, the signal received through the second antenna  442 , as a PRx signal, may be transmitted to the communication processor  260  through the second antenna tuning circuit  442   a , the switch  450 , the first RFFE  431 , and the RFIC  410 . Further, the signal received through the third antenna  443 , as a DRx signal, may be transmitted to the communication processor  260  through the third antenna tuning circuit  443 a, the second RFFE  432 , and the RFIC  410 .

According to various embodiments, different path loss may occur in the four antenna transmission paths because the lengths of the transmission paths and components disposed on the transmission paths are different from each other. 
       FIG. 4D  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. 
     Referring to  FIG. 4D , according to various embodiments, an electronic device (e.g., the electronic device  101  of  FIG. 1 ) may include a processor (e.g., including processing circuitry)  120 , a communication processor (e.g., including processing circuitry)  260 , an RFIC  410 , a first RFFE  431 , a second RFEE  432 , a third RFEE  433 , a first antenna  441 , a second antenna  442 , a third antenna  443 , a fourth antenna  444 , and a fifth antenna  445 . 
     According to various embodiments, upon transmission, the RFIC  410  may convert a baseband signal generated by the communication processor  260  into a radio frequency (RF) signal used in the first communication network or the second communication network. For example, the RFIC  410  may transmit an RF signal used in the first communication network to the first antenna  441  or the second antenna  442  through the first RFFE  431  and the first switch  451 .

     According to various embodiments, upon transmission, the RFIC  410  may convert a baseband signal generated by the communication processor  260  into a radio frequency (RF) signal used in the second communication network. For example, the RFIC  410  may transmit an RF signal used in the second communication network to the third antenna  443  or the fourth antenna  444  through the second RFFE  432  and the second switch  452 . Further, the RFIC  410  may transmit an RF signal used in the second communication network to the first antenna  441  or the second antenna  442  through the second RFFE  432 , the second switch  452 , and the first switch  451 . 
     According to various embodiments, upon transmission, the RFIC  410  may convert a baseband signal generated by the communication processor  260  into a radio frequency (RF) signal used in the third communication network. For example, the RFIC  410  may transmit an RF signal used in the third communication network to the fifth antenna  445  through the third RFEE  433 . 
     According to various embodiments, upon reception, an RF signal may be obtained from the first communication network through the first antenna  441  or the second antenna  442  and may go through the first switch  451  and be preprocessed through the first RFFE  431 . The RFIC  410  may convert the RF signal preprocessed through the first RFFE  431  into a baseband signal to be processed by the communication processor  260 .

According to various embodiments, the second communication network and the third communication network may support communication of different frequency bands even though they are the same LTE networks. For example, the second communication network may be a communication network that transmits and receives high-band LTE (e.g., B41 band) signals, and the fourth communication network may be a communication network that transmits and receives low-band LTE (e.g., B5 band, B12 band, or B71 band) signals. According to various embodiments, the low-band frequency may be 0.6 GHz to 1.0 GHz, the mid-band frequency may be 1.7 GHz to 2.2 GHz, and the high-band frequency may be 2.3 GHz to 3.7 GHz.

     According to various embodiments, when the first communication network performs transmission/reception of the N41 band signal of the 5G network, the first RFFE  431  may be designed to be appropriate for processing the signal corresponding to the 5G network, the second RFFE,  432  may be designed to be appropriate for processing the high-band LTE signal (e.g., B41 band signal), and the third RFFE  433  may be designed to be appropriate for the low-band LTE signal (e.g., B5 band signal). At least one of the second RFFE  432  and the third RFFE  433  may be configured in the form of a power amplitude module including duplexer (PAMiD). 
     According to various embodiments, a frequency band of a signal transmitted through the first RFFE  431  and a frequency band of a signal transmitted through the second RFFE  432  may be the same, similar, or different. For example, the frequency band of the signal transmitted through the first RFFE  431  may be an N41 band (2.6 GHz), which is a frequency band of a 5G network, and the frequency band of the signal transmitted through the second RFFE  432  may be a B41 band (2.6 GHz), which is a frequency band of an LTE network. In this case, the first RFFE  431  and the second RFFE  432  process the same or similar frequency band signals, but the first RFFE  431  may be designed to enable signal processing suitable for the characteristics of the 5G network, and the second RFFE  432  may be designed to enable signal processing suitable for the characteristics of the LTE network. 
     According to various embodiments, the first RFFE  431  may be designed to process a signal of a wider frequency bandwidth than the second RFFE  432 . For example, the first RFFE  431  may be designed to process up to a frequency bandwidth of  100  MHz, and the second RFFE  432  may be designed to process up to a frequency bandwidth of  60  MHz. 
     According to various embodiments, the first RFFE  431  may include additional components (e.g., an SPDT switch for transmitting SRSs, a filter to prevent and/or reduce interference between the 5G signal and the WIFI signal of similar bands, a component to separate the WIFI signal from the reception signal, and a duplexer to separate different 5G band signals) different from the second RFFE  432  for multi-band support or for signal processing appropriate for the characteristics of 5G network. Since the first RFFE  431  further include an additional component as compared to the second RFFE  432 , greater attenuation (e.g., path loss) may occur due to the processing of the transmission signal. For example, although each of the power amplifier of the first RFFE  431  and the power amplifier of the second RFFE  432  is controlled to transmit the same power of signal by the RFIC  410 , since the path loss of the first 
     RFFE,  431  is larger than the path loss of the second RFFE  432 , the magnitude of the signal transmitted through the first antenna module  441  may be smaller than the magnitude of the signal transmitted through the second antenna module  442 .

       FIG. 6  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. Referring to  FIG. 6 , a plurality of RFFEs  611 ,  612 ,  613 ,  621 ,  622 ,  623 ,  631 ,  632 ,  633 , and  640  may be connected to at least one RFIC  410 . The plurality of RF 1 -ths  611 ,  612 ,  613 ,  621 ,  622 ,  623 ,  631 ,  632 ,  633 , and  640  may be connected to a plurality of antennas  651 ,  652 ,  661 ,  662 ,  671 ,  672 ,  673 ,  681 ,  691 , and  692 , respectively. 
     According to various embodiments, a 1-1th RFFE  611  and a 2-1th RFFE  621  may be connected with a first main antenna  651  and a second main antenna  661 , respectively.

       FIG. 7  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. Referring to  FIG. 7 , a plurality of power amplitude modules (PAMs)  711 ,  751 ,  761 , and  771  and/or a plurality of front end modules (FEMs)  721 ,  731 , and  741  may be connected to at least one RFIC  410 . The plurality of PAMs  711 ,  751 ,  761 , and  771  and/or the plurality of FEMs  721 ,  731 , and  741  each may be connected to at least one antenna  712 ,  713 ,  722 ,  732 ,  733 ,  742 ,  743 ,  752 ,  762 ,  772 , and  773 . 
     Each of the plurality of PAMs  711 ,  751 ,  761 , and  771  may include a power amplifier PA and may amplify the transmission signal by the power amplifier and transmit it through the antenna  712 ,  713 ,  752 ,  761 ,  772 , or  773 . Each of the plurality of PAMs  711 ,  751 ,  761 , and  771  may include a low noise amplifier (LNA) and may amplify the reception signal by the power amplifier and transmit it to the RFIC  410 . PAM # 3   761  may include at least one diplexer or at least one duplexer and may be configured in the form of a power amplitude module including duplexer (PAMiD). PAM # 3   761  may transmit the data received through the antenna  762  to the LNA  763  through the diplexer or duplexer. The data received by the LNA  763  may be low-noise amplified and then transmitted to the RFIC  410 . Each of the plurality of FEMs  721 ,  731 , and  741  may include a low noise amplifier (LNA) and may amplify the reception signal by the power amplifier and transmit it to the RFIC  410 . 
     According to various embodiments, PAM # 1   711  may transmit/receive a mid-band or high-band 5G frequency (e.g., N1 band or N3 band) signal. PAM # 2   751  may transmit and receive an ultra high-band 5G frequency (e.g., N78 band) signal. For example, when the electronic device  101  operates as SA, it may transmit/receive a 5G frequency signal through PAM # 1   711  or PAM #N  771 . When the electronic device  101  operates as EN-DC, it may transmit/receive a 5G frequency signal and an LTE frequency signal through PAM # 1   711  and PAM #N  771 , respectively. 
     According to various embodiments, when the electronic device  101  operates as CA or EN-DC, a frequency band to be supported may increase. The use of the FEM component and the antenna path may be restricted due to size limitations on the electronic device  101 . The electronic device  101  may be configured to process multiple frequency components in one component and antenna so as to process various complicated frequency bands of components. According to various embodiments, a refarming band using a part of the LTE frequency band as a 5G frequency band may be used. In a frequency band where only LTE or NR exists, when the electronic device  101  processes signals in the RFIC (e.g., the RFIC  410 ), a mixer in the RFIC may separate and process signals using a modulation/demodulation technique suitable for the RAT. According to various embodiments, in an environment where an LTE service and an NR service coexist, and proximate frequency components are mixed for NSA, the electronic device  101  may have difficulty in separating the LTE and NR signals only with the FEM component. For example, if the mixed signal of the LTE signal and the NR signal is input to the RFIC  410 , the RFIC  410  of the electronic device  101  converts the signal with respect to one RAT in the modulation/demodulation process, and thus the signal of another RAT may be lost or remain as a noise component. 
     According to various embodiments, in order to process the reframing band of signals without loss when operating as NSA, the electronic device  101  should simultaneously receive two signals of the same frequency band and process them through different RF paths in the RFIC so as to reconstruct the original signal without interference between the LTE signal and the NR signal. 
       FIG. 8  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. When the NR band signal uses the refarming band of the LTE band, the LTE band and the NR band may be adjacent to each other. Referring to  FIG. 8 , according to various embodiments, the NR band signal transmitted from an NR base station  806  (e.g., gNB) may be received by a first FEM  801  through a first antenna  803 . The LTE band signal transmitted from the LTE base station  805  (e.g., eNB) may be received by the first FEM  801  through the first antenna  803 . The first FEM  801  may include a band pass filter (BPF)  801   a , a power amplifier  801 b, and a low noise amplifier  801 c. The NR band signal and the LTE band signal received by the first FEM  801  may be filtered through the band pass filter  801 a and may be amplified through the low noise amplifier  801 c. The NR band signal and the LTE band signal amplified by the low noise amplifier  801 c may be input to the mixer  410   a  through the first LNA of the RFIC  410 . The mixer  410   a  may output LTE data by mixing the NR band signal and the LTE band signal with a carrier frequency of the LTE band. 
     According to various embodiments, the NR band signal transmitted from the NR base station  806  (e.g., gNB) may be received by a second FEM  802  through a second antenna  804 . 
     The LTE band signal transmitted from the LTE base station  805  (e.g., eNB) may be received by the second FEM  802  through the second antenna  804 . The second FEM  802  may include a band pass filter (BPF)  802   a , a power amplifier  802 b, and a low noise amplifier  802   c . The NR band signal and the LTE band signal received by the FEM  802  may be filtered through the band pass filter  802   a  and may be amplified through the low noise amplifier  802   c . The NR band signal and the LTE band signal amplified by the low noise amplifier  802   c  may be input to the mixer  410   a  through the second LNA of the RFIC  410 . The mixer  410   a  may output NR data by mixing the NR band signal and the LTE band signal with a carrier frequency of the NR band. 
     For example, when the electronic device  101  operates as EN-DC, the first FEM  801  may process a signal of a B1 band or B3 band, and the second FEM  802  may process a signal of an N1 band or N3 band, which is the refarming band of the B1 band or the B3 band.

A first sub antenna  921  among the sub antennas may be formed of metal at an outer portion of the housing. The first sub antenna  921  may be used to receive 2G, 3G, LTE or 
     NR signals. Among the sub antennas, a third sub antenna  923  or a fourth sub antenna  924  may be configured in the form of a metal slit in at least a portion of the housing.

The fifth sub antenna  925  may be used to receive Wi-Fi signals. The sixth sub antenna  926  may be used for reception of NR signals (e.g., N77 or N78). Among the sub antennas, a seventh sub antenna  927  may be configured in the form of LDS or a metal slit in at least a portion of the housing. The seventh sub antenna  927  may be used for reception of GPS, 2G, 3G, or LTE signals or transmission and reception of NR signals. According to various embodiments, it will be readily understood by one of ordinary skill in the art that the arrangement and use of the antennas of the electronic device  101  are not limited to those shown and described above. 
     Hereinafter, a method for controlling the power of a transmission signal in an electronic device according to various embodiments is described with reference to  FIGS. 10 to 17 . According to various embodiments, when operating as CA or EN-DC, the electronic device  101  may use some of the antennas available in the corresponding FEM to simultaneously transmit/receive signals corresponding to multiple frequencies. The electronic device  101  (e.g., a communication processor (e.g., the auxiliary processor  123 , the wireless communication module  192 , the first communication processor  212 , the second communication processor  214 , or the integrated communication processor  260 )) may change or adjust the setting of the antenna tuning circuit (e.g., the first antenna tuning circuit  441   a , the second antenna tuning circuit  442   a , or the third antenna tuning circuit  443 a) connected to the antenna so as to increase the transmission/reception performance of the frequency component for the selected antenna. The antenna gain of the corresponding antenna may be changed according to a change in the setting of the antenna tuning circuit. 
     The total radiation power (TRP) of the signal output from the electronic device  101  through the antenna is the sum of the antenna gain and the transmit power and may be expressed as Equation 1 below.

FIG. 10  is a diagram illustrating example change in antenna gain in carrier aggregation according to various embodiments. Referring to  FIG. 10 , according to various embodiments, when the electronic device  101  operates as SA or transmits a signal of a single frequency band without CA, the antenna gain  1010  may adjust the setting of the antenna tuning circuit to be optimized for the frequency of the primary cell (PCell)  1001 . 
     According to various embodiments, at least one secondary cell (SCell)  1002  and  1003  may exist in a multi-RAT (e.g., EN-DC) or multi-band (e.g., CA) environment, and as illustrated in  FIG. 10 , it is possible to change the antenna gain by changing the setting of the antenna tuning circuit considering the performance of a plurality of frequency components so that multiple frequency bands (PCell  1001 +SCell #m  1002 +SCell #n  1003 + . . . ) may be used simultaneously. When the antenna tuning circuit is set considering the performance of the plurality of frequency components, the antenna gain  1020  of the PCell may be relatively reduced, so that the total radiation power may be reduced. 
     According to various embodiments, as illustrated in  FIG. 10 , when the antenna gain is changed considering multiple frequency components, if the antenna control module for controlling the antenna tuning circuit and the transmit power control module for controlling the transmit power operate separately, it may be difficult for the transmit power control module to identify a change in total radiation power. When the transmit power control module fails to identify the change in total radiation power, the electronic device  101  may have difficulty in additional compensation for the transmit power due to a reduction in antenna gain. 
     According to various embodiments, when the transmit power is changed in the transmit power control module, if it is not temporarily synchronized with the operation of the antenna control module, an unexpected change in the transmit power may occur. For example, the electronic device  101  may correct the transmit power through transmit power control (TPC) by the base station, but since the antenna gain may continue to change until the TPC control is completed, it may be difficult to constantly control the transmit power of the electronic device  101 . 
     In various embodiments, when the antenna gain of at least one antenna is changed in an environment in which two or more Tx signals are transmitted, such as EN-DC or ULCA, it is possible to prevent and/or reduce a situation where the total radiation power departs from the set reference and allow the electronic device  101  to transmit constant transmit power by integratedly managing the state of the antenna control module (e.g., the antenna control module  1116  of FIG.  11 )) and the power control module (e.g., the transmit power control module  1115  of  FIG. 11 ). 
     In various embodiments, the electronic device  101  may determine an antenna path change or a path loss change that occurs due to a hardware limitation and may perform control so that the total radiation power becomes an optimal value according to each situation by adjusting the transmit power based on the setting value of the transmit power defined to fit for each state. 
       FIG. 11  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. Referring to  FIG. 11 , according to various embodiments, an electronic device  101  may include at least one sensor  1100 , a processor (e.g., including processing circuitry)  120  (e.g., an application processor, hereinafter referred to as an application processor with reference to  FIG. 11 ), a communication processor (e.g., including processing circuitry)  260 , a transmission circuit  1121 , a reception circuit  1122 , an RFFE  1130 , an antenna switching module  1140 , a plurality of antenna tuning circuits  1150 - 1  to  1150 -N, and a plurality of antennas  1160 - 1  to  1160 -N. The communication processor  260  may include a memory  1110 , a transmit power control module (e.g., including transmit power control circuitry)  1115 , and an antenna control module (e.g., including antenna control circuitry)  1116 . The memory  1110  may store CP event information  1111 , frequency band information  1112 , AP event information  1113 , and a mapping table  1114 . According to an embodiment, although not shown, a memory (e.g., the memory  130  of  FIG. 1 ) included in the electronic device  101  may be used separately from the communication processor  260 , in addition to, or alternatively to the memory  1110 . For example, at least a portion of the separate memory  130  may include a common portion accessible by both the application processor  120  and the communication processor  260 . The application  120  and/or the communication processor  260  may store at least some of the CP event information  1111 , frequency band information  1112 , AP event information  1113 , or mapping table  1114  in the separate memory  130 . 
     According to various embodiments, the transmit power control module  1115  may control the power of the transmission signal. For example, as illustrated in  FIG. 18 , according to various embodiments, the maximum transmittable power for each transmission path may be set considering at least one of the maximum transmittable power (P-MAX power (PeMax) received from each communication network (e.g., a base station), the maximum transmittable power (UE Tx MAX power (PcMax) for each transmission path set by the electronic device  101 , or an SAR event maximum transmittable power (SAR EVENT MAX power) set corresponding to each SAR event considering the specific absorption rate (SAR) backoff. For example, the maximum transmittable power may be determined as a minimum value among the plurality of the above exemplified maximum transmittable powers (e.g., P-MAX power, UE Tx MAX power, and SAR EVENT MAX power). The transmit power control module  1115  of the electronic device  101  may set the transmit power based on the TPC controlled by the base station within the set maximum transmittable power. For example, the electronic device  101  may set the transmit power of the PUSCH for the subframe i when the radio access technology (RAT) is E-UTRA based on Equation 2 below.

     PCMAX is the maximum output power according to the power class of the electronic device  101 . For example, PcmAx may be UE maximum output power defined in 3 rd  generation partnership project (3GPP) technical specification (TS) 36.101, but is not limited thereto. M PUSCH (i) is the number of resource blocks allocated to the electronic device  101 . P O     _     PUSCH (j) is the sum of P O     _     NOMINAL     _     PUSCH (j) (a parameter specified by the cell) and P O     _     UE     PUSCH   (j) (a parameter specified by the electronic device  101 ). PL is the downlink path-loss measured by the electronic device  101 . The scaling factor α(j) may be determined in a higher layer considering the pathloss mismatch between the uplink channel and the downlink channel Δ TF (i) is the modulation and coding scheme (MCS) compensation parameter or the transport format (TF) compensation parameter. f(i) is the value adjusted by downlink control information (DCI) from the base station after initial setting. The electronic device  101  may set the smaller of PCMAX and the sum of M PUSCH (i), P O     _     PUSCH (j), the product of the scaling factor a(j) and PL, Δ TF (i), and f(i), as the transmit power of the PUSCH. At least some of the parameters for Equation 1 may follow, e.g., 3GPP TS 36.213. Alternatively, the electronic device  101  may set the transmit power of the PUSCH according to 3GPP TS 38.213, e.g., when the RAT is NR. The above-described example has been described for the transmit power for the PUSCH. The transmit power may be set not only for the PUSCH but also for various cases (e.g., SRS, PUCCH, PUSCH, and PRACH), and the setting method may follow, e.g., 3GPP TS 36.213 or 3GPP TS 38.213, but there is no limitation. 
     According to various embodiments, the electronic device  101  may identify the above-described maximum transmittable power. The maximum transmittable power of the electronic device  101  may be PeMax, and it may be set according to the power class of the electronic device  101  based on, e.g., 3GPP TS 36.101 or 3GPP TS 38.101, but the setting scheme is not limited to a specific one. If the power class of the electronic device  101  is PC  3 , the maximum transmittable power may be, e.g., 23 dBm. The maximum transmittable power may be, e.g., a smaller value among values set in response to output power limiting events, such as PcMax and SAR events. The electronic device  101  may manage (or identify) the output power corresponding to the SAR event that allows for compliance with the SAR restriction regulation. For example, in response to a grip event, which is one of the SAR events, 16 dBm may be managed (or identified) as a limited output power. In this case, the electronic device  101  may identify, as the maximum transmittable power, 16 dBm, which is the smaller value of PeMax (e.g., 23 dBm) and output power (e.g., 16 dBm) corresponding to the SAR event. The event in which the output power is limited is not limited to the SAR event. For example, when dynamic power sharing (DPS) is being performed, the electronic device  101  may identify that the smaller of the UE maximum transmittable power and the limited maximum transmittable power by the DPS is the maximum transmittable power for specific RAT. 
     According to various embodiments, the antenna control module  1116  may control the antenna switching module  1140  according to the communication situation (e.g., EN-DC or CA) of the electronic device  101  to select a transmission path and antenna  1160 - 1  to  1160 -N of each transmission signal from among the plurality of transmission paths and the plurality of antennas. The antenna control module  1116  may change the antenna gain by adjusting the setting of the antenna tuning circuit  1150 - 1  to  1150 -N corresponding to the selected antenna  1160 - 1  to  1160 -N. 
     For example, the antenna control module  1116  may change the antenna gain for a specific transmission signal by changing the antennas  1160 - 1  to  1160 -N or changing the setting of the antenna tuning circuit  1150 - 1  to  1150 -N. 
     According to various embodiments, the setting of the antenna tuning circuit  1150 - 1  to  1150 -N may be set to a specific constant value. A state or setting that may affect the antenna gain in the electronic device  101  may be defined as an event. The events that may affect the antenna gain may be classified into a CP event related to the communication processor  260  and an AP event related to the application processor  120 . 
     For example, the CP event may refer, for example, to an event generated during communication between the base station  1170  and the electronic device  101 , and may include at least one of, e.g., uplink carrier aggregation (CA), downlink CA, antenna diversity (e.g., 2 Rx or 4 Rx), multiple-input and multiple-output (MIMO), antenna switching, a call event, dual-connectivity (DC), or a difference between reference signal received powers (RSRPs). The CP event may be stored as CP event information  1111  in the memory  1110 . 
     The AP event may refer, for example, to an event received by the application processor  120 , other than the CP event and may include at least one of, e.g., a grip event sensed by a grip sensor, a proximity event sensed by a proximity sensor, an event related to an image sensor, or an event related to connection of an external connecting terminal. The AP event may be stored as AP event information  1113  in the memory  1110 . For example, the application processor  120  may generate an AP event based on a signal or information sensed from at least one sensor  1100  (e.g., a grip sensor, a proximity sensor, or an image sensor) and may transmit the generated AP event to the communication processor  260 . The communication processor  260  may store the AP event received from the application processor  120  as AP event information  1113  in the memory  1110 . As another example, when the AP event is stored in the memory  130  that exists separately outside the communication processor  260 , the application processor  120  may store the AP event in a common portion of the memory  130 , and the communication processor  260  may access the common portion to read the AP event. 
     According to various embodiments, the electronic device  101  may declare the variable “[Multi RAT Radiation Status]” as shown in Table 6 below to synchronize event information between the transmit power control module  1115  and the antenna control module  1116  and may set a function capable of reading or writing frequency band information, AP event information, and CP event information from or to the memory  1110 .

     According to various embodiments, when transmitting a transmission signal, the transmit power control module  1115  of the electronic device  101  may identify the “[Multi RAT Radiation Status]” stored in the memory  1110  (e.g., by identifying the CP event information  1111  or the AP event information  1113 ) and, if it is determined that a new event has been updated, fetch the corresponding event information from the memory  1110  through the function defined in Table 6. The transmit power control module  1115  may identify the event information fetched from the memory  1110  to identify the current antenna configuration state and may determine the transmit power based on the mapping table  1114  set considering the antenna gain corresponding to each antenna configuration state. For example, the mapping table  1114  may be configured as shown in Table 7 below.

     Referring to Table 7, the AP event “0×01” may indicate a grip event sensed by the grip sensor. The CP event “0×20” may indicate EN-DC. For example, each CP event of Table 7 may include EN-DC operations, such as B1-N5, B1-N78, B5-N41, and B7-N3. According to various embodiments, the transmit power control module  1115  may identify the CP event information  1111 , the AP event information  1113 , and the frequency band information  1112  from the memory  1110  and may identify the maximum transmittable power of each transmission signal from the mapping table  1114  as exemplified in Table 7, based on the identified information. 
     According to various embodiments, if it is identified that the frequency band information  1112  is B1 or N5, the AP event information  1113  is “0×01” corresponding to the grip event, and the CP event information  1111  is “0×20” corresponding to EN-DC, the transmit power control module  1115  may identify that the current state is mapped to field no. 1 through the mapping table  1114  of Table 7. The transmit power control module  1115  may control the transmit power of the B1 signal by setting 170 mW, which is the first transmit power (Tx Power # 1 ) set corresponding to field no. 1, as the maximum transmittable power for the B1 signal and control the transmit power of the N5 signal by setting 170 mW, which is the second transmit power (Tx Power # 2 ), as the maximum transmittable power for the N5 signal. 
     According to various embodiments, if it is identified that the frequency band information  1112  is B1 or N78, the AP event information  1113  is “0×01” corresponding to the grip event, and the CP event information  1111  is “0×20” corresponding to EN-DC, the transmit power control module  1115  may identify that the current state is mapped to field no. 2 through the mapping table  1114  of Table 7. The transmit power control module  1115  may control the transmit power of the B1 signal by setting 180 mW, which is the first transmit power (Tx Power # 1 ) set corresponding to field no. 2, as the maximum transmittable power for the B1 signal and control the transmit power of the N78 signal by setting 180 mW, which is the second transmit power (Tx Power # 2 ), as the maximum transmittable power for the N78 signal. 
     According to various embodiments, if it is identified that the frequency band information  1112  is B5 or N41, the AP event information  1113  is “0×01” corresponding to the grip event, and the CP event information  1111  is “0×20” corresponding to EN-DC, the transmit power control module  1115  may identify that the current state is mapped to field no. 3 through the mapping table  1114  of Table 7. The transmit power control module  1115  may control the transmit power of the B5 signal by setting 190 mW, which is the first transmit power (Tx Power # 1 ) set corresponding to field no. 3, as the maximum transmittable power for the B5 signal and control the transmit power of the N41 signal by setting 190 mW, which is the second transmit power (Tx Power # 2 ), as the maximum transmittable power for the N41 signal. 
     According to various embodiments, if it is identified that the frequency band information  1112  is B7 or N3, the AP event information  1113  is “0×01” corresponding to the grip event, and the CP event information  1111  is “0×20” corresponding to EN-DC, the transmit power control module  1115  may identify that the current state is mapped to field no. 4 through the mapping table  1114  of Table 7. The transmit power control module  1115  may control the transmit power of the B7 signal by setting 200 mW, which is the first transmit power (Tx Power # 1 ) set corresponding to field no.  4 , as the maximum transmittable power for the B7 signal and control the transmit power of the N3 signal by setting 200 mW, which is the second transmit power (Tx Power # 2 ), as the maximum transmittable power for the N3 signal. According to various embodiments, referring to Table 7, when an antenna gain decrease due to an unintentional change in antenna characteristics occurs outside of the electronic device  101 , such as the user&#39;s grip, the user&#39;s grip may be determined through the grip sensor, and the AP event corresponding to the user&#39;s grip, as the AP event information  1113 , may be stored in the memory  1110 . The electronic device  101  may identify the AP event corresponding to the user&#39;s grip and, since the power of the transmission signal transmitted through the antenna corresponding to the position gripped by the user may be attenuated by the user&#39;s grip, the electronic device  101  may increase the power of the transmission signal by a set value (e.g., 3 dB) and transmit it. 
     According to various embodiments, when the base station  1170  transmits a control message so that the electronic device  101  operates with a CA of 2 CCs or more, the electronic device  10  may determine the CA state through a control message (e.g., an RRCconnection reconfiguration message) received from the base station  1170 . The electronic device  101  may identify the CA state and, if the band of the PCell is a low-band and is thus not affected by the SAR, the electronic device  101  may further increase the transmit power by 0.5 dB. For example, the electronic device  101  may identify PCell information through the frequency band information  1112  and may identify the CA state through the CP event information  1111 . The electronic device  101  may compensate for the transmit power by +0.5 dB more by referring to the mapping table  1114  based on the identified information. 
     According to various embodiments, when a condition requiring that each antenna-related setting be changed occurs (e.g., a changing of antenna or a change in the setting of the antenna tuning circuit), the antenna control module  1116  may control each antenna circuits  1150 - 1  to  1150 -N by identifying the AP event information  1113  and the CP event information  1111  stored in the memory  1110 . For example, the antenna control module  1116  may record the frequency band information and event information used to update “[Multi RAT Radiation Status]” in the memory  1110  using a function as shown in Table 8 below.

     According to various embodiments, when the “[Multi RAT Radiation Status]” is updated by the antenna control module  1116 , the transmit power control module  1115  may read each event information (e.g., the CP event information  1111  and the AP event information  1113 ) and the frequency band information  1112  stored in the memory  1110  and determine whether the transmit power is changed at the same timing as the time when a change in the antenna-related setting occurs. For example, the transmit power control module  1115  may compensate for the maximum transmittable power corresponding to the antenna gain attenuated due to a change in the antenna-related setting by determining whether mapping is performed through the mapping table  1114 . 
     Hereinafter, various embodiments of adjusting the maximum transmittable power using the mapping table described above are described with reference to  FIGS. 12 to 15 . 
       FIG. 12  is a diagram illustrating an example antenna arrangement of an electronic device according to various embodiments. Referring to  FIG. 12 , when the electronic device  101  operates as EN-DC or NE-DC, the electronic device  101  may simultaneously transmit the LTE signal and the NR signal through the first antenna  1210  and the second antenna  1220 . For example, a mid-band LTE signal (e.g., a B1 band signal) may be transmitted through the first antenna  1210  disposed at the lower end of the electronic device  101 , and a mid-band NR signal (e.g., an N3 band signal) may be transmitted through the second antenna  1220  disposed at the upper end of the electronic device  101 . 
     According to various embodiments, when transmitting only the LTE signal of the B1 band, the electronic device  101  may set the first antenna  1210  disposed at the lower end of the electronic device  101  as a default antenna and may control to transmit the B1 band signal through the first antenna  1210 . When transmitting only the NR signal of the N3 band, the electronic device  101  may control to transmit the N3 band signal through the first antenna  1210  set as the default antenna because the NR signal is identical or similar in frequency characteristics to the LTE signal of the B1 band. 
     According to various embodiments, when the electronic device  101  simultaneously transmits the B1 band signal and the N3 band signal as the NSA condition is met while transmitting the B1 band signal through the first antenna, the electronic device  101  may operate as EN-DC. For example, when the B1 band of LTE and the N3 band of NR use the same antenna or component, the N3 band signal and the B1 band signal may overlap so that signal loss may occur. When the electronic device  101  operates as EN-DC while transmitting the B1 band signal and thus simultaneously transmits the N3 band signal and the B1 band signal, the electronic device  101  may control to transmit the NR signal of the N3 band through the second antenna  1220  disposed at the upper end. The antenna control module  1116  of the electronic device  101  may store antenna related information (e.g., selected antenna information or configuration information for the antenna tuning circuit) set according to the EN-DC operation, as CP event information  1111 . 
       FIG. 13  is a signal flow diagram illustrating example EN-DC operations of an electronic device according to various embodiments. Referring to  FIG. 13 , according to various embodiments, an electronic device (the electronic device  101  of  FIG. 1 ) (e.g., the communication processor  260  of the electronic device) may operate as EN-DC by simultaneously connecting to a first communication network (e.g., NR) and a second communication network (LTE). According to various embodiments, in a state in which the electronic device  101  is connected with the second communication network (e.g., eNB)  1302 , the second communication network  1302  may transmit a gNB addition Request to the first communication network  1303  (e.g., gNB) in operation  1310 . The first communication network  1303  may transmit a gNB addition Request Acknowledge to the second communication network  1302  in operation  1320 . 
     According to various embodiments, the second communication network  1302  may transmit an RRC Connection Reconfiguration to the electronic device  101  in operation  1330 . The electronic device  101  may transmit an RRC Connection Reconfiguration Complete to the second communication network  1302  in operation  1340 . The second communication network  1302  may transmit a gNB Reconfiguration Complete to the first communication network  1303  in operation  1350 . 
     The electronic device  101  may perform UE-gNB cell detection with the first communication network  1303  in operation  1360  and may perform a RACH procedure in operation  1370 , thereby operating as EN-DC through the first communication network  1303  and the second communication network  1302 . 
     According to various embodiments, the RRC Connection Reconfiguration in operation  1330  may include band/bandwidth (BW) information for the first communication network  1303  to be connected as shown in Table 9 below.

     The electronic device  101  may receive an RRC Connection Reconfiguration message including Table 9 above and may store the frequency band included in the message, as frequency band information  1112 , in the memory  1110 . 
     When the transmit power control module  1115  of the electronic device  101  cannot distinguish between the antenna to transmit the signal for the NR band in SA and the antenna to transmit the signal for the NR band in NSA, it is possible to relatively reduce the maximum transmittable power by setting the transmit power based on the one with poorer antenna gain of the two antennas. As described above, in various embodiments, the transmit power control module  1115  of the electronic device  101  may set the maximum transmittable power to be relatively higher based on the antenna gain set for the antenna selected according to the EN-DC operation. 
     According to various embodiments, when the electronic device  101  transmits a transmission signal using the first antenna  1210  disposed at the lower end, it may be affected by an AP event related to the first antenna  1210 . For example, when a grip event occurs due to the user&#39;s grip on the electronic device  101  or when an access-related event is caused by OTG/USB or earjack connection, the power of the transmission signal may be affected. According to various embodiments, when the electronic device  101  transmits a transmission signal using the second antenna  1220  disposed at the upper end, it may be affected by an AP event related to the second antenna  1220 . For example, when a proximity event occurs due to call reception in the electronic device  101  or when an image sensor-related event occurs according to a camera operation, the power of the transmission signal may be affected. 
     According to various embodiments, the electronic device  101  may apply a different power limitation due to the influence by the SAR according to the frequency as shown in Table 10 below.

     For example, since the mapping table  1114  stored in the memory  1110  of the electronic device  101  is relatively less affected by the SAR when the frequency band information  1112  is the low-band, the maximum transmittable power may be set so that the transmit power is not limited by the SAR. 
     According to various embodiments, referring back to  FIG. 12 , when the electronic device  101  is connected with the NR communication network of the N3 band while in connection with the LTE communication network of the B1 band and operates as EN-DC, the electronic device  101  may control to transmit the B1 band signal through the first antenna  1210  and the N3 band signal through the second antenna  1220  based on the EN-DC operation as described above. 
     When the electronic device  101  operates as EN-DC, since LTE is an anchor, the electronic device  101  may set the total transmit power for the B1 band signal to be higher than the total transmit power for the N3 band signal. 
     For example, when the user&#39;s grip is detected in the EN-DC operation, if the transmit power control module  1115  cannot distinguish between the first antenna  1210  and the second antenna  1220 , the transmit power of both the first antenna  1210  and the second antenna  1220  may be limited to 19.5 dBm according to Table 10 above. According to various embodiments, when the transmit power control module  1115  of the electronic device  101  distinguishes between the first antenna  1210  and the second antenna  1220 , since the user&#39;s grip does not influence the second antenna  1220  disposed at the upper end, it is possible to increase the performance of transmit power by refraining from applying the transmit power limitation due to the grip sensor to the N3 band signal transmitted through the second antenna  1220 . 
     According to various embodiments, when the user performs a voice call using the electronic device  101 , if the transmit power control module  1115  cannot distinguish between the first antenna  1210  and the second antenna  1220 , the transmit power of both the first antenna  1210  and the second antenna  1220  may be limited by 2 dB in consideration of the effect on the head. According to various embodiments, when the transmit power control module  1115  of the electronic device  101  distinguishes between the first antenna  1210  and the second antenna  1220 , it may be applied to each antenna whether to limit the transmit power separately for VoLTE or VoNR which is a condition for the voice call. For example, when a voice call is performed with VoLTE, since the voice packets are transferred through the first antenna  1210  at the lower end, the transmit power control module  1115  of the electronic device  101  may further compensate for the power that may be reduced due to the user&#39;s grip, for the signal transmitted through the first antenna  1210  and, since the second antenna  1220  disposed at the upper end reduces in spacing from the head during phone talk and may thus influence the SAR, it may reduce the transmit power by 2 dB only under the EN-DC condition. 
       FIG. 14  is a diagram illustrating an example antenna arrangement of an electronic device according to various embodiments. Referring to  FIG. 14 , a specific NR band signal (e.g., an N78 band signal) may be transmitted through a first antenna  1410  disposed on a side surface of the electronic device  101  or a second antenna  1420  disposed at an upper end of the electronic device  101 . 
     According to various embodiments, when the electronic device  101  cannot transmit all transmission signals through the antenna disposed at the lower end, the electronic device  101  may transmit an NR band signal through the second antenna  1420  disposed at an upper end of the electronic device  101 . For example, the N78 band signal may be transmitted through the first antenna  1410  disposed on the side surface of the electronic device  101 . Since high frequency signals, such as the N78 band signal are less diffracted, refracted, and transmitted and travel straight, the position of the first antenna  1410 , rather than the second antenna  1420 , may ensure better performance by the high frequency characteristics. In contrast, as the position of the antenna approaches the lower end of the electronic device  101 , more influenced may be had by the user&#39;s grip, and high frequency signals may be more influenced by the range where the antenna is blocked by the human body. 
     According to various embodiments, considering both the loss and benefit according to the position of the antenna, the NR band signal may selectively use the first antenna  1410  or the second antenna  1420 , and the second antenna  1420  may be used as a transmission path of the sounding reference signal (SRS). 
       FIG. 15  is a block diagram illustrating an example configuration of an electronic device according to various embodiments. Referring to  FIG. 15 , according to various embodiments, an electronic device  101  may include a communication processor (e.g., including processing circuitry)  260  (e.g., at least one of the first communication processor  212 , the second communication processor  214 , or the integrated communication processor  260 ) and an RFIC  410  (e.g., at least one of the first RFIC  222 , the second RFIC  224 , the third RFIC  226 , or the fourth RFIC  228 ). The electronic device  101  may include at least one of at least one amplifier  1530 ,  1550 , and  1570 , at least one switch  1535 ,  1555 , and  1575 , or at least one antenna  1541 ,  1542 ,  1543 ,  1544 ,  1561 ,  1562 ,  1563 ,  1564 ,  1581 ,  1582 ,  1583 , and  1584 . For convenience of description, although  FIG. 15  illustrates that elements for RF signal transmission are included in the electronic device  101 , it will be easily appreciated by one of ordinary skill in the art that elements for receiving and/or processing RF signals may further be included in the electronic device  101 . Although  FIG. 15  illustrates that at least one antenna  1541 ,  1542 ,  1543 ,  1544 ,  1561 ,  1562 ,  1563 ,  1564 ,  1581 ,  1582 ,  1583 , and  1584  is disposed outside the electronic device  101 , according to various embodiments, the at least one antenna  1541 ,  1542 ,  1543 ,  1544 ,  1561 ,  1562 ,  1563 ,  1564 ,  1581 ,  1582 ,  1583 , and  1584  may be included in the housing forming the exterior of the electronic device  101  and/or in at least a portion of the housing. 
     According to various embodiments, the communication processor  260  may support a plurality of RATs (e.g., LTE communication and NR communication). In the communication processor  260 , protocol stacks (e.g., a 3GPP protocol stack for LTE communication and a 3GPP protocol stack for NR communication) for the plurality of RATs may be defined (or stored). The protocol stack may receive a data packet (or Internet protocol (IP) packet) from the application processor (e.g., the processor  120 ) (or the transmission control protocol (TCP)/IP stack) and process and output it. If the RF signal received from the outside is converted into a baseband signal and received, the protocol stack may process the baseband signal and provide it to the application processor (e.g., the processor  120  (or TCP/IP stack)). The protocol stack may perform an operation for signaling (e.g., control). 
     According to various embodiments, the RF circuit  410  may process the signal (e.g., a baseband signal) from the communication processor  260  and output an RF signal. The at least one amplifier  1530 ,  1550 , and  1570  may amplify and provide the received RF signal. As the at least one amplifier  1530 ,  1550 , and  1570  is controlled, the output power of the RF signal may be adjusted. The SRS of NR communication may be transmitted through each of the first antenna  1541 , the second antenna  1542 , the third antenna  1543 , and the fourth antenna  1544 . For example, the electronic device  101  may support 1T4R. The first antenna  1541  may be an antenna capable of performing both transmission and reception, and the second antenna  1542 , the third antenna  1543 , and the fourth antenna  1544  may be antennas for reception. The communication processor  260  may identify SRS transmit power and may control the amplifier  1530  so that the identified SRS transmit power is applied to the port for each antenna. The switch  1535  may selectively connect the RFIF  410  and the antenna so that the RF signal is applied to a designated antenna. For example, the connection state of the switch  1535  may be controlled so that the SRS is sequentially applied through each of the antennas  1541 ,  1542 ,  1543 , and  1544 . For example, in the example of  FIG. 15 , the SRS is shown as transmitted in the n78 frequency band, but the frequency band is not limited thereto. It will be easily appreciated by one of ordinary skill in the art that the number of antennas  1541 ,  1542 ,  1543 , and  1544  for NR communication is merely an example and is not limited thereto. 1T4R is merely an example. The electronic device  101  may support 1T2R, 2T4R, or other capabilities, and it will be easily appreciated by one of ordinary skill in the art that the number of antennas, the number of amplifiers, and/or the connection relationship between the antennas is not limited to a specific one. 
     According to various embodiments, the electronic device  101  may support carrier aggregation (CA) for LTE. For example, in the embodiment of  FIG. 15 , the frequency band of B7 associated with the PCell may be selected, and at least one frequency band (not shown) associated with the SCell may be selected. The number of component carriers (CCs) for CA is not limited to a specific one. However, depending on hardware (HW) restrictions and the frequency band operated by the operator, 2 or more and 32 or less CCs may be typically operated. The signal associated with the PCell may be transmitted/received via at least one of the antennas  1561 ,  1562 ,  1563 , and  1564  via the amplifier  1550  and/or the switch  1555 . The signal associated with the SCell may be transmitted/received via at least one of the antennas  1581 ,  1582 ,  1583 , and  1584 , via the amplifier  1570  and/or the switch  1575 . The numbers of antennas  1561 ,  1562 ,  1563 , and  1564  and antennas  1581 ,  1582 ,  1583 , and  1584  are also merely examples. According to various embodiments, a plurality of frequency bands may correspond to one antenna. For example, the antennas  1561 ,  1562 ,  1563 , and  1564  may correspond to ultra high-bands (e.g., N78 and N79) as well as high-bands (e.g., N7, N38, N39, N40, and N41). Accordingly, it will be easily appreciated by one of ordinary skill in the art that the number of antennas may be smaller than that of  FIG. 15 . 
     According to various embodiments, the electronic device  101  may transmit an SRS based on the first RAT (e.g., NR communication). For example, the electronic device  101  may report the UE capability of 1T4R to the network and may receive an SRS configuration from the network. The electronic device  101  may identify transmission time points of four SRSs for transmitting the SRS based on the SRS configuration. The SRS transmission time may be referred to as an SRS slot. The electronic device  101  may control the amplifier  1530  and/or the switch  1535  to transmit the first SRS through the first antenna  1541  during the first SRS slot, the second SRS through the second antenna  1542  during the second SRS slot, the third SRS through the third antenna  1543  during the third SRS slot, and the fourth SRS through the fourth antenna  1544  during the fourth SRS slot. In the embodiment of  FIG. 15 , the case in which the electronic device  101  performs CA for any one RAT (e.g., LTE) has been described. However, it is merely an example, and various embodiments of the disclosure may also be applied even when any one RAT does not perform CA. 
     According to various embodiments, for the N78 band signal, a 1T4R SRS path may exist as illustrated in  FIG. 15 , and four SRS paths may be implemented using a 2way switch. For example, when the second antenna  1420  is used to transmit the N78 band signal, since the 1T4R path of the SRS is used, a signal attenuation of 3 dB may be caused by a path loss due to the use of the DPDT switch. 
     Referring back to  FIG. 14 , the N78 band signal may be transmitted using the first antenna  1410  as a default path. According to various embodiments, an antenna switching condition may occur. For example, when the grip is sensed by the grip sensor installed near the first antenna  1410 , or when the difference between the RSRP of the first antenna  1410  and the RSRP of the second antenna  1420  is a set value or more, the transmission antenna of the N78 band signal may be switched from the first antenna  1410  to the second antenna  1420 . According to the antenna switching, additional path loss may occur in transmit power, and even when the power of the transmission signal is changed, the magnitude of the actual power radiated from the antenna may be lower due to the path loss. According to various embodiments, the electronic device  101  may be configured to switch the antenna when the user&#39;s grip is detected by the grip sensor installed near the first antenna  1410  and the difference in RSRP between the first antenna  1410  and the second antenna  1420  is a set value or more (e.g., 6 dB). For example, the difference in RSRP between the first antenna  1410  and the second antenna  1420 , as a CP event, may be stored in the memory  1110 . According to various embodiments, when the N78 band is connected, the electronic device  101  may be configured to compensate for the path loss, e.g., 4 dB, which may occur, considering the CP event and the AP event (e.g., a grip event). 
     According to various embodiments, if the rank indicator (RI) increases so that the number of actual physical antennas increases, the electronic device  101  may perform processing of the reception signal as well as processing of the transmission signal through the second antenna  1420 . According to various embodiments, as the number of frequency components to be considered in one antenna increases, the influence of the antenna gain may increase. For example, when the second antenna  1420  transmits the N78 band signal, the decrease in the antenna gain for the transmission signal may be defined as in Equation  3  below.

     Referring to Table 11, according to various embodiments, conditions for changing the antenna gain of the transmission signal may be distinguished by setting the conditions under which the Rx and Tx frequency components influence the antenna, as CP events, so that it is possible to determine the compensation value for the transmit power considering the antenna gain change due to a change in the setting of the antenna tuning circuit and the antenna change. According to various embodiments, when the transmit antenna is changed in the inter 
     ULCA condition, the above-described embodiments may be applied. For example, in the case of inter ULCA, the combination of frequency bands may be set as “LOW+MID” or “LOW+HIGH”. Since the reference of the maximum transmittable power and the reference of the maximum transmittable power according to the human body influence by SAR are different, PCell and SCell information may be processed separately. For example, when there are two types of ULCA support combinations as described above, the following combinations may be possible for the PCell and SCell. 
     1. Low (PCell)+Mid (SCell) 
     2. Mid (PCell)+Low (SCell) 
     3. Low (PCell)+High (SCell) 
     4. High (PCell)+Low (SCell) 
     According to various embodiments, the limit of the maximum transmittable power in the 2Tx condition cannot be set so that the sum of two maximum transmittable powers is higher than one maximum transmittable power. For example, when the magnitude of the sum of the maximum transmit powers of the two transmission signals is set to 23 dB, Tx 0  and Tx  1  each may be set to 20 dB. According to various embodiments, since the signal of the SCell may be determined according to the signal quality of the PCell, the importance of the signal of the PCell may be processed to be relatively higher. Accordingly, the transmit power of the SCell may be lowered so that the magnitude of the maximum transmittable power is appropriate for a set reference while the PUSCH power of the PCell is met. According to various embodiments, when considering the effect of SAR, it is not necessary to limit the transmit power for the low-band signal, and when the set maximum transmittable power is met and no influence is had on the adjacent signal, the maximum transmittable power may be additionally compensated. 
     According to various embodiments, to increase the transmit power of the low-band, the transmit power control module  115  may additionally compensate for the transmit power by addressing the limit to the transmit power of the SCell due to a high transmit power of the PCell based on the information for the PCell and the information for the SCell during transmit power control. For example, when the low-band is the PCell, if the transmit power control module  1115  does not distinguish between the PCell and the SCell, the power of the PCell may be lowered so that the signal of the SCell may be output within the maximum transmittable power. For example, if the maximum transmittable power of the two signals is set to 23 dB, since the SCell may nearly output if it is output in 23 dB although the PCell is the low-band, the maximum transmit power may be limited to be lower by 1 to 2 dB even when the PCell may output the maximum power. According to various embodiments, when the transmit power control module  1115  distinguishes between the PCell and the SCell, it may be aware of the frequency band information for the PCell. When the PCell is the low-band, only 0.3 mW/g of influence may be had when the low-band is output in 23 dB with respect to the actual SAR of lg, although the transmit power of the SCell is output up to 19.5 dBm, no issue may occur with the reference of the maximum transmittable power. For example, in the case of inter ULCA, there are two base stations, and the maximum transmit power might not be requested in the channel quality of the two base stations. 
     Thus, according to various embodiments, it is possible to enhance the performance of uplink throughput (TP) and increase the channel quality of the SCell by raising the transmit power of the SCell with the performance of the transmit power of the PCell ensured, by compensating the SCell for the maximum transmittable power according to the SAR reference. According to various embodiments, the measurement reference of the SAR may refer, for example, to the amount of electromagnetic wave energy absorbed by the unit mass ( 1 kg or  1 g) of the human body per unit time and, since the measurement reference includes a temporal element, e.g., unit time, it may also be considered how long the corresponding frequency component has been output. For example, the frequency band where the TDD is applied in the LTE and NR communication system alternately uses Tx and Rx in the same frequency band, the influence of the SAR may be smaller as compared with the FDD. For example, in a case where the transmission signal operates in TDD mode according to a CP event, although the frequency band is a mid-band or high-band which is a frequency having a high human body absorption rate, the maximum transmittable power may be set to be identical or similar to the band with a low influence of the SAR. 
     According to various embodiments, the RFIC  410  of the electronic device  101  may transmit a signal to each antenna using a microstrip on a printed circuit board (PCB). When an RF transmission path is formed through the microstrip, conductor loss, dielectric loss, radiation loss, and leakage loss may occur in the vicinity of the RF transmission path. For example, in relation to conductor loss, a skin effect may occur in the case of a high-frequency signal (e.g., an N77 band signal or an N78 band signal) due to physical characteristics and, when the high-frequency signal is output, the noise component of the signal may be generated in the main board. When the high-frequency signal is transmitted through an antenna (e.g., the fourth sub antenna  924  of  FIG. 9 ) adjacent to the camera, the noise caused by the conductor loss may affect the camera through the main board, causing malfunction of the camera. According to various embodiments, in a case where whether to operate the camera is received as an AP event, and a high-frequency signal (e.g., an N78 band signal) is transmitted through an antenna (e.g., the fourth sub antenna  926  of  FIG. 9 ) adjacent to the camera, the mapping table  1114  may be set so that the maximum transmittable power is further limited.
