Description

Technical Field

[0001] The present disclosure relates to an electronic device and a method for configuring a path of a transmission signal in the electronic device. Background Art

[0002] Following recent developments in mobile communication technology, there has been a widespread use of portable terminals that provide various functions, and efforts have been made to develop a 5G communication system to meet the growing demand for wireless data services. To achieve a high data transmission rate and provide a faster data transmission speed, in addition to the frequency bands used in 3G communication systems and Long Term Evolution (LTE) communication systems, it has been considered to implement a 5G communication system in a higher frequency band (e.g., 25 - 60 GHz band).

[0003] For example, to mitigate radio wave path loss in the millimeter wave (mmWave) band and increase the radio wave propagation distance, technologies regarding beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antennas have been discussed in 5G communication systems.

[0004] To transmit a signal from an electronic device to a communication network (e.g., a base station), data generated by a processor or a communication processor inside the electronic device can undergo signal processing through a radio frequency integrated circuit (RFIC) and a radio frequency front end (RFFE), and then can be transmitted to the outside of the electronic device through at least one antenna. Summary of the Invention

[0005] Technical Problem

[0006] An electronic device may provide multiple transmission paths (Tx paths) to transmit a signal to a communication network (e.g., a base station). The multiple Tx paths provided by the electronic device may include RFIC and / or RFFE circuits for each path. In addition, each RFFE circuit may be connected to one antenna or multiple antennas, and the multiple Tx paths may thus be divided into multiple antenna Tx paths corresponding to one or more antennas.

[0007] Since the respective Tx paths have different lengths and different components are provided on the corresponding Tx paths, different path losses may occur in the multiple antenna Tx paths. In addition, since the respective antennas corresponding to the respective antenna Tx paths are placed at different positions on the electronic device, different antenna losses may occur. Therefore, if the Tx antenna or Tx path is configured by only considering the difference in the received signal strength of each path (e.g., reference signal received power (PSRP)), a Tx path or antenna that transmits a relatively small amplitude of Tx power may be configured because the power actually radiated through the antenna (e.g., radiated power) is not considered.

[0008] For example, when considering only the difference in reference signal received power (PSRP) between the signals received through each path when configuring the Tx path, a Tx path or antenna with a relatively low level of radiated power can be configured to transmit the Tx signal. In addition, when not considering the Tx / Rx imbalance after the configuration of the antenna tuning circuit corresponding to each antenna when configuring the Tx path, a situation may occur where, although the radiated power of the current Tx path is good, a switch to another Tx path occurs, or a situation where, although the radiated power of the current Tx path is poor, no Tx path switch occurs.

[0009] Embodiments of the present disclosure may provide an electronic device and a method for configuring a Tx signal path in the electronic device, wherein, when transmitting a Tx signal in an electronic device including multiple antenna Tx paths, an optimal Tx path can be configured by considering the received signal strength and the Tx maximum power for each Tx path to determine the Tx path or whether to switch the antenna.

[0010] Embodiments of the present disclosure may provide an electronic device and a method for configuring a Tx signal path in the electronic device, wherein, when transmitting a Tx signal in an electronic device including multiple antenna Tx paths, an optimal Tx path can be configured by considering the received signal strength for each Tx path and the Tx / Rx imbalance of each antenna to determine the Tx path or whether to switch the antenna.

[0011] Technical solution

[0012] According to various example embodiments, an electronic device may include: a communication processor, at least one radio frequency integrated circuit (RFIC) connected to the communication processor, and a plurality of antennas, each of the plurality of antennas being connected to at least one RFIC through at least one radio frequency front-end (RFFE) circuit and being configured to transmit a signal corresponding to at least one communication network, wherein the communication processor is configured to identify information related to the strength of the received signal received through each of the plurality of antennas, identify the maximum transmit power setting corresponding to the transmit path of each of the plurality of antennas, and control the electronic device to transmit a transmit signal through at least one of the plurality of antennas, wherein the at least one antenna is selected based at least on the identified information related to the strength of the received signal and the maximum transmit power.

[0013] According to various example embodiments, an electronic device may include: a communication processor, at least one radio frequency integrated circuit (RFIC) connected to the communication processor, and a plurality of antennas, each of the plurality of antennas being connected to at least one RFIC through at least one radio frequency front-end (RFFE) circuit and configured to transmit signals corresponding to at least one communication network, wherein the communication processor is configured to identify information related to the strength of received signals received through each of the plurality of antennas, identify configuration values of antenna tuning circuits corresponding to the antennas that transmit transmission signals among the plurality of antennas, and control the electronic device to transmit a transmission signal through at least one of the plurality of antennas, wherein the at least one antenna is selected based at least on the identified information related to the strength of the received signals and the identified configuration values of the antenna tuning circuits.

[0014] According to various example embodiments, a method for configuring a transmission path by an electronic device includes: identifying information related to the strength of received signals received through each of a plurality of antennas, the electronic device including a communication processor, at least one radio frequency integrated circuit (RFIC) connected to the communication processor, and a plurality of antennas, each of the plurality of antennas being connected to at least one RFIC through at least one radio frequency front-end (RFFE) circuit and configured to transmit signals corresponding to at least one communication network, identifying a maximum transmit power setting corresponding to the transmission path of each of the plurality of antennas, and transmitting a transmission signal through at least one of the plurality of antennas, wherein the at least one antenna is selected based at least on the identified information related to the strength of the received signals and the maximum transmit power.

[0015] Advantageous Effects

[0016] According to various example embodiments, in an electronic device providing a plurality of antenna Tx paths, in addition to the received signal strength of each Tx path, an optimal Tx path that maximizes the power actually radiated by the antenna may be configured by considering the Tx maximum power and / or Tx / Rx imbalance of the antenna tuning circuit.

[0017] Therefore, even in a situation with a poor field state, compared with a conventional Tx path configuration method that only considers the received signal strength, the probability of maintaining the connection between the base station and the terminal can be increased, and signals can be transmitted with a relatively high level of radiated power and a high-performance modulation type, thereby having a high uplink throughput (T-Put).

[0018] In addition, according to various example embodiments, when a high level of Tx path loss occurs as a result of the antenna configuration, the Tx path may be switched so that the antenna loss of the Tx signal is reduced, thereby reducing the current consumption. Description of the Drawings

The communication module 190 may include one or more communication processors capable of operating independently of the processor 120 (e.g., an application processor (AP)), and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). Each of these communication modules may communicate with the external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules may be implemented as a single component (e.g., a single chip), or these various types of communication modules may be implemented as multiple separate components (e.g., multiple chips). The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an international mobile subscriber identity (IMSI)) stored in the user identification module 196.

According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme to be used in a communication network (such as the first network 198 or the second network 199) may be selected from the plurality of antennas by, for example, the communication module 190. Subsequently, a signal or power may be transmitted or received between the communication module 190 and an external electronic device via the at least one selected antenna. According to an embodiment, additional components (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

[0059] According to various embodiments, the antenna module 197 may form a millimeter-wave antenna module. According to an embodiment, the millimeter-wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and a plurality of antennas (e.g., an array antenna), wherein the RFIC is disposed on a first surface (e.g., a bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a specified high-frequency band (e.g., a millimeter-wave band), and the plurality of antennas are disposed on a second surface (e.g., a top surface or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the specified high-frequency band.

The electronic device 101 may provide the result as at least part of a reply to the request with or without further processing of the result. To this end, for example, cloud computing technology, distributed computing technology, mobile edge computing (MEC) technology, or client-server computing technology may be used.

[0062] Figure 2A is a block diagram 200 showing an example configuration of an electronic device 101 for supporting legacy network communication and 5G network communication according to various embodiments. Refer to Figure 2A, the electronic device 101 may include a first communication processor (e.g., including processing circuitry) 212, a second communication processor (e.g., including processing circuitry) 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front end (RFFE) 232, a second RFFE 234, a first antenna module (e.g., including at least one antenna) 242, a second antenna module (e.g., including at least one antenna) 244, a third antenna module (e.g., including at least one antenna) 246, and an antenna 248. The electronic device 101 may also include a processor (e.g., including processing circuitry) 120 and a memory 130. The second network 199 may include a first cellular network 292 and a second cellular network 294. According to an embodiment, the electronic device 101 may further include Figure 1 at least one of the components shown, and the second network 199 may further include at least one different network. According to an embodiment, the first communication processor 212, the second communication processor 214, the first RFIC 222, the second RFIC 224, the fourth RFIC 228, the first RFFE 232, and the second RFFE 234 may form at least a part of the wireless communication module 192. According to an embodiment, the fourth RFIC 228 may be omitted or included as part of the third RFIC 226.

[0063] The first communication processor 212 may establish a communication channel for a frequency band for wireless communication with the first cellular network 292 and support traditional network communication through the established communication channel. According to various embodiments, the first cellular network may be a traditional network, including a second generation (2G), 3G, 4G, or Long Term Evolution (LTE) network. The second communication processor 214 may establish a communication channel corresponding to a designated frequency band (e.g., from about 6 GHz to about 60 GHz) among the frequency bands to be used for wireless communication with the second cellular network 294 and support 5G network through the established communication channel. According to various embodiments, the second cellular network 294 may be a 5G network defined by 3GPP. Additionally, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another designated frequency band (e.g., about 6 GHz or lower) among the frequency bands to be used for wireless communication with the second cellular network 294 and support 5G network communication.

[0064] The first communication processor 212 can send data to and receive data from the second communication processor 214. For example, data classified to be sent through the second cellular network 294 can be sent through the first cellular network 292. In this case, the first communication processor 212 can receive the data to be sent from the second communication processor 214. For example, the first communication processor 212 can send and receive data through an interface 213 between the first communication processor 212 and the second communication processor 214. The interface 213 between the processors can be implemented as, for example, a Universal Asynchronous Receiver / Transmitter (UART) (e.g., a High-Speed UART (HS-UART) or a Peripheral Component Interconnect Express (PCIe) interface), but the type is not limited thereto. Alternatively, the first communication processor 212 and the second communication processor 214 can exchange control information and packet data information by using, for example, a shared memory. The first communication processor 212 can send and receive various types of information to and from the second communication processor 214, such as sensing information, information about output strength, and resource block (RB) allocation information.

[0065] Depending on the implementation, the first communication processor 212 may not be directly connected to the second communication processor 214. In this case, the first communication processor 212 can send data to and receive data from the second communication processor 214 through the processor 120 (e.g., an application processor). For example, the first communication processor 212 and the second communication processor 214 can send and receive data through the processor 120 (e.g., an application processor) and an HS-UART interface or a PCIe interface, but the type of the interface is not limited thereto. Alternatively, the first communication processor 212 and the second communication processor 214 can exchange control information and packet data information by using the processor 120 (e.g., an application processor) and a shared memory.

[0066] According to an embodiment, the first communication processor 212 and the second communication processor 214 can be implemented in a single chip or a single package. According to various embodiments, the first communication processor 212 or the second communication processor 214 can be formed in a single chip or a single package with the processor 120, the co-processor 123, or the communication module 190. For example, as Figure 2B shown, the unified communication processor 260 can support the function of communicating with both the first cellular network 292 and the second cellular network 294.

[0067] During transmission, the first RFIC 222 can convert the baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal in the range of approximately 700 MHz to approximately 3 GHz for use in the first cellular network 292 (e.g., a legacy network). During reception, the RF signal can be obtained from the first network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242), and the RF signal can be pre-processed via the RFFE (e.g., the first RFFE 232). The first RFIC 222 can convert the pre-processed RF signal into a baseband signal such that the signal can be processed by the first communication processor 212.

[0068] During transmission, the second RFIC 224 can convert the baseband signal generated by the first communication processor 212 or the second communication processor 214 into an RF signal in a Sub6 band (e.g., approximately 6 GHz or lower), referred to hereinafter as a 5G Sub6 RF signal, for use in the second cellular network 294 (e.g., a 5G network). During reception, the 5G Sub6 RF signal can be obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244), and the 5G Sub6 RF signal can be pre-processed via the RFFE (e.g., the second RFFE 234). The second RFIC 224 can convert the pre-processed 5G Sub6 RF signal into a baseband signal such that the signal can be processed by the corresponding communication processor among the first communication processor 212 and the second communication processor 214.

[0069] The third RFIC 226 can convert the baseband signal generated by the second communication processor 214 into an RF signal in a 5G Above6 band (e.g., approximately 6 GHz to approximately 60 GHz), referred to hereinafter as a 5G Above6 RF signal, for use in the second cellular network 294 (e.g., a 5G network). During reception, the 5G Above6 RF signal can be obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248), and the 5G Above6 RF signal can be pre-processed via the third RFFE 236. The third RFIC 226 can convert the pre-processed 5G Above6 RF signal into a baseband signal such that the signal can be processed by the second communication processor 214. According to an embodiment, the third RFFE 236 can be formed as part of the third RFIC 226.

[0070] According to an embodiment, the electronic device 101 may include a fourth RFIC 228 that is separate from or at least part of the third RFIC 226. In this case, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter referred to as an IF signal) in an intermediate frequency band (e.g., from about 9 GHz to about 11 GHz), and then transmit the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G Above6 RF signal. During reception, a 5G Above6 RF signal may be received from a second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248), and the third RFIC 226 may convert the 5G Above6 RF signal into an IF signal. The fourth RFIC 228 may convert the IF signal into a baseband signal so that the signal can be processed by the second communication processor 214.

[0071] According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least part of a single chip or a single package. According to various embodiments, when Figure 2A either the first RFIC 222 and the second RFIC 224 in 2B are implemented as a single chip or a single package, the first RFIC 222 and the second RFIC 224 may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE 232 and the second RFFE 234 to convert a baseband signal into a signal in a frequency band supported by the first RFFE 232 and / or the second RFFE 234, and the converted signal may be transmitted 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 a single package. According to an embodiment, at least one of the first antenna module 242 or the second antenna module 244 may be omitted or combined with the other antenna module to process RF signals in multiple corresponding frequency bands.

[0072] According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed on the same substrate to form a 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 PCB). In this case, the third RFIC 226 may be placed on a partial area (e.g., a lower surface) of a second substrate (e.g., a sub-PCB) separated from the first substrate, and the antenna 248 may be placed on another partial area (e.g., an upper surface) of the second substrate to form the third antenna module 246. The third RFIC 226 and the antenna 248 may be disposed on the same substrate, thereby reducing the length of the transmission line therebetween. That is, for example, the loss (e.g., attenuation) of signals in a high frequency band (e.g., from about 6 GHz to about 60 GHz) used in 5G network communication due to the transmission line can be reduced. As a result, the electronic device 101 may improve the quality or speed of communication with the second network 294 (e.g., a 5G network).

[0073] According to an embodiment, the antenna 248 may be formed as an antenna array including a plurality of antenna elements that can be used for beamforming. In this case, the third RFIC 226 may include, for example, a plurality of phase shifters 238 corresponding to the plurality of antenna elements as part of the third RFFE 236. During transmission, each of the plurality of phase shifters 238 may convert the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device 101 (e.g., a base station of a 5G network) through a corresponding antenna element. During reception, each of the plurality of phase shifters 238 may convert the phase of a 5G Above6 RF signal received from the outside through a corresponding antenna element to the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device 101 and the outside.

[0074] The second cellular network 294 (e.g., a 5G network) may operate independently (e.g., stand-alone (SA)) or be connected (e.g., non-stand-alone (NSA)) to the first cellular network 292 (e.g., a legacy network). For example, the 5G network may include only an access network (e.g., a 5G radio access network (RAN) or a next-generation RAN (NG RAN)) without including a core network (e.g., a next-generation core (NGC)). In this case, after accessing the access network of the 5G network, the electronic device 101 may access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., an evolved packet core (EPC)). Protocol information for communicating with the legacy network (e.g., LTE protocol information) or protocol information for communicating with the 5G network (e.g., new radio (NR) protocol information) may be stored in the memory 230 to be accessed by other components (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

[0075] Figure 3A , Figure 3B and Figure 3C A wireless communication system configured to provide a network for traditional communications and / or 5G communications according to various embodiments is shown. Figure 3A , Figure 3B and Figure 3C , the network environments 300a to 300c may include at least one of a conventional network and a 5G network. The conventional network may include, for example, a 3GPP standard 4G or LTE base station 340 (e.g., eNodeB (eNB)) supporting wireless access to the electronic device 101, and an evolved packet core (EPC) 342 managing 4G communications. The 5G network may include, for example, a new radio (NR) base station 350 (e.g., gNodeB (gNB)) supporting wireless access to the electronic device 101 and a fifth generation core (5GC) 352 managing 5G communications of the electronic device 101.

[0076] According to various embodiments, the electronic device 101 may send and receive control messages and user data through traditional communication and / or 5G communication. The control message may include, for example, a message related to at least one of security control, bearer establishment, authentication, registration, or mobility management of the electronic device 101. The user data may refer to, for example, user data not included in the control message sent and received between the electronic device 101 and the core network 330 (e.g., EPC 342).

[0077] refer to Figure 3A According to an embodiment, the electronic device 101 can use at least a portion of a traditional network (e.g., an LTE base station 340 and an EPC 342) to send at least one of a control message or user data to at least a portion of a 5G network (e.g., an NR base station 350, a 5GC 352), and receive at least one of a control message or user data from at least a portion of the 5G network.

[0078] According to various embodiments, the network environment 300a may provide wireless communication dual connectivity (DC) to the LTE base station 340 and the NR base station 350, and may include a network environment for sending control messages to and receiving control messages from the electronic device 101 through a core network 330 of one of the EPC 342 or the 5GC 352.

[0079] According to various embodiments, in a 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 may operate as a secondary node (SN) 320. The MN 310 may be connected to the core network 330 to send and receive control messages. The MN 310 and the SN 320 may be connected to each other through a network interface and may send / receive messages related to radio resource (e.g., communication channel) management to / from each other.

[0080] According to various embodiments, 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 sent and received through the LTE base station 340 and the EPC 342, and user data may be sent and received through at least one of the LTE base station 340 or the NR base station 350.

[0081] According to various embodiments, the MN 310 may include the NR base station 350, 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 sent and received through the NR base station 350 and the 5GC 352, and user data may be sent and received through at least one of the LTE base station 340 and the NR base station 350.

[0082] Referring to Figure 3B , according to various embodiments, the 5G network may include the NR base station 350 and the 5GC 352, and may send and receive control messages and user data independently of the electronic device 101.

[0083] Referring to Figure 3C , according to various embodiments, the traditional network and the 5G network may independently provide data transmission and reception. For example, the electronic device 101 and the EPC 342 may send and receive control messages and user data through the LTE base station 340. As another example, the electronic device 101 and the 5GC 352 may send and receive control messages and user data through the NR base station 350.

[0084] According to various embodiments, the electronic device 101 may register with at least one of the EPC 342 and the 5GC 352 to send and receive control messages.

[0085] According to various embodiments, the EPC 342 or the 5GC 352 may interact with each other to manage the communication of the electronic device 101. For example, the mobility information of the electronic device 101 may be sent and received through the interface between the EPC 342 and the 5GC 352.

[0086] As described above, the dual connection through the LTE base station 340 and the NR base station 350 may be referred to as an E-UTRA New Radio Dual Connection (EN-DC).

[0087] Hereinafter, with reference to FIGS. 4a, 4b, 4c, 4d, 4e, 5a, 5b, 5c, 5d, Figure 6 and Figure 7 the structure and operation of the electronic device 101 according to various embodiments will be described in detail. Although one communication processor 260, 610 and one RFIC 410, 620 are shown connected to a plurality of RFFEs 431, 432, 433, 631, 632, 711 to 740 in each of the drawings of the embodiments described later, the various embodiments described later are not limited thereto. For example, according to various embodiments described below, a plurality of communication processors 212, 214 and / or a plurality of RFICs 222, 224, 226, 228 may be connected to a plurality of RFFEs 431, 432, 433, 631, 632, 711 to 740, as Figure 2A or Figure 2B shown.

[0088] FIGS. 4a, 4b, 4c, 4d and 4e are block diagrams of an electronic device according to various embodiments.

[0089] According to various embodiments, Figure 4A is an example of a case where the electronic device 101 includes two antennas 441, 442 and switches a transmission path, Figure 4B is an example of a case where the electronic device 101 includes three antennas 441, 442, 443 and switches a transmission path.

[0090] Referring Figure 4A , an electronic device according to various embodiments (e.g., Figure 1 the electronic device 101 in

[0091] According to various embodiments, during transmission, the RFIC 410 may convert a baseband signal generated by the communication processor 260 into a radio frequency (RF) signal to be used in a communication network. For example, the RFIC 410 may transmit the RF signal to be used in the communication network to the first antenna 441 or the second antenna 442 through the first RFFE 431 and the switch 450.

[0092] According to various embodiments, a transmission path for transmission from the RFIC 410 to the first antenna 441 through the first RFFE 431 and the switch 450 may be referred to as "Antenna Transmission Path 1 (Ant Tx 1)". A transmission path for transmission from the RFIC 410 to the second antenna 442 through the first RFFE 431 and the switch 450 may be referred to as "Antenna Transmission Path 2 (Ant Tx 2)". According to various embodiments, due to differences in the length of each transmission path and / or components placed on the corresponding transmission path, the transmission paths of the two antennas may have different path losses. In addition, since the antennas corresponding to the respective antenna transmission paths (e.g., the first antenna 441, the second antenna 442) are placed at different positions on the electronic device 101, different antenna losses may occur.

[0093] According to various embodiments, the first antenna tuning circuit 441a may be connected to the front end of the first antenna 441, and the second antenna tuning circuit 442a may be connected to the front end of the second antenna 442. The communication processor 260 may adjust the configured values of the first antenna tuning circuit 441a and the configured values of the second antenna tuning circuit 442a, thereby adjusting (e.g., tuning) the characteristics of signals (e.g., transmission signals (Tx)) transmitted and received through each connected antenna and signals (e.g., received signals (Rx)). Detailed embodiments thereof will be described later with reference to Figure 5A 、 Figure 5B 、 Figure 5C and Figure 5D describe its detailed embodiments.

[0094] According to various embodiments, the communication processor 260 may control the switch 450 to perform a configuration such that the first RFFE 431 is connected to the first antenna tuning circuit 441a and the first antenna 441. At this time, 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 441a, and the antenna 441.

[0095] According to various embodiments, the first antenna 441 may be configured as a primary Rx (PRx) antenna, and the second antenna 442 may be configured as a diversity Rx (Drx) antenna. The electronic device 101 may receive and decode signals transmitted from a base station through the first antenna 441 and / or the second antenna 442. For example, the signal received through the first antenna 441 is a PRx signal and may be transmitted to the communication processor 260 through the first antenna tuning circuit 441a, the switch 450, the first RFFE 431, and the RFIC 410. In addition, the signal received through the second antenna 442 is a DRx signal and may be transmitted to the communication processor 260 through the second antenna tuning circuit 442a, the switch 450, the second RFFE 432, and the RFIC 410.

[0096] According to various embodiments, the first RFFE 431 may include at least one duplexer or at least one diplexer to process a transmit signal (Tx) and a receive signal (PRx) together. The second RFFE 432 may include at least one duplexer or at least one diplexer to process a transmit signal (Tx) and a receive signal (DRx) together.

[0097] According to various embodiments, the communication processor 260 may control the switch 450 to perform a configuration such that the first RFFE 431 is connected to the second antenna tuning circuit 442a and the second antenna 442. At this time, the transmit 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 442a, and the second antenna 442.

[0098] According to various embodiments, when the first RFFE 431 is configured to be connected to the second antenna tuning circuit 442a and the second antenna 442 as described above, the second antenna 442 may be configured as a primary Rx antenna (PRx), and the first antenna 441 may be configured as a diversity Rx antenna (Drx). The electronic device 101 may receive and decode signals transmitted from a base station through the first antenna 441 and the second antenna 442. For example, the signal received through the second antenna 442 is a PRx signal and may be transmitted to the communication processor 260 through the second antenna tuning circuit 442a, the switch 450, the first RFFE 431, and the RFIC 410. In addition, the signal received through the first antenna 441 is a DRx signal and may be transmitted to the communication processor 260 through the first antenna tuning circuit 441a, the switch 450, the second RFFE432, and the RFIC 410.

[0099] According to various embodiments, the communication processor 260 may configure or change (e.g., switch) an antenna to transmit a transmission signal (Tx) by controlling a switch 450 according to various configuration conditions. According to various embodiments, the communication processor 260 may configure a transmission path corresponding to an antenna capable of radiating the transmission signal (Tx) with maximum power. For example, as Figure 4A shown, when transmitting a transmission signal in an electronic device 101 including a plurality of antenna transmission paths, the best antenna transmission path may be configured in consideration of the maximum transmit power and the channel environment (e.g., the intensity of the received signal) corresponding to each antenna (e.g., the first antenna 441 and the second antenna 442). The communication processor 260 may determine the best antenna transmission path and control the switch 450 so that the transmission signal is transmitted through the determined best antenna transmission path.

[0100] According to various embodiments, for each configured time period (e.g., 640 ms) or when a specific event occurs (e.g., when a SAR event occurs or the electric field situation changes rapidly, or a signaling from a base station), the electronic device 101 (e.g., the communication processor 260) may identify whether the transmission path of the transmission signal has changed (or whether the antenna has been switched).

[0101] For example, the electronic device 101 (e.g., the communication processor 260) may identify information related to the received signal strength of each reception path (e.g., reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), received signal code power (RSCP), signal-to-noise ratio (SNR), or signal-to-interference-and-noise ratio (SINR)). Refer to Figure 4A, the electronic device 101 may identify information related to the intensity of a received signal (e.g., PRx) received through the first antenna 441 (e.g., the first RSRP) and information related to the intensity of a received signal (e.g., DRx) received through the second antenna 442 (e.g., the second RSRP). The communication processor 260 may determine an optimal transmission path based on the intensity difference between the received signals with respect to multiple reception paths (e.g., the second RSRP (dBm) - the first RSRP (dBm)), and may determine whether to change the transmission path according to the determined optimal transmission path. For example, the communication processor 260 may calculate an average value of the difference between the received signal intensities calculated in a previous measurement period and the difference between the currently measured received signal intensities (e.g., the average RSRP). For example, when the difference between the intensities of the currently measured received signals is equal to or greater than a first threshold (e.g., "high threshold") (e.g., when the RSRP changes rapidly), or the calculated average value is equal to or greater than a second threshold (e.g., "low threshold") (e.g., when consecutive RSRP differences occur), the transmission path of the transmitted signal may be changed by controlling the switch 450 (e.g., the transmission antenna may be switched).

[0102] According to various embodiments, when determining whether to change the transmission path, the electronic device 101 (e.g., the communication processor 260) may also consider the maximum transmit power (Tx maximum power) of each transmission path from the difference between the received signal intensities. The maximum transmit power may indicate the maximum transmit power of each antenna transmission path of the electronic device 101 (e.g., the transmission path transmitted through the first antenna 441 and the transmission path transmitted through the second antenna 442 in Figure 4A . An example of determining the maximum transmit power will be described in detail below with reference to Figure 8 .

[0103] Figure 8 is a block diagram illustrating a method for determining the maximum transmit power according to various embodiments. Refer to Figure 8, According to various embodiments, the maximum transmit power of a SAR event configured in response to each SAR event (SAR event maximum (SAR EVENT MAX) power), the maximum transmit power received from each communication network (e.g., a base station) (P-max (P-MAX) power (PeMax)), the maximum transmit power of each transmit path configured in the electronic device 101 (UE Tx MAX ((UE Tx MAX) power (PcMax)), and the specific absorption rate (SAR) backoff may be considered to configure the maximum transmit power of each transmit path. For example, the maximum transmit power may be determined as the minimum value among the above-mentioned multiple maximum transmit powers (e.g., P-MAX power, UE Tx MAX power, SAR EVENT MAX power), but is not limited thereto. According to various embodiments, the maximum transmit power of a SAR event may be differently configured according to each SAR event (e.g., a grip event or a proximity event). Hereinafter, examples of determining the maximum transmit power of each transmit path based on the above-mentioned multiple maximum transmit powers will be described in detail.

[0104] According to various embodiments, the maximum transmit power (P-MAX power (PeMax)) received from a communication network (e.g., a base station) may be differently configured according to each communication network or the power class (PC) that the electronic device can support. For example, when the power class is PC2, the maximum transmit power may be determined as a value within a range configured based on 26 dBm (e.g., 25 to 27 dBm), and when the power class is PC3, the maximum transmit power may be determined as a value within a range configured based on 23 dBm (e.g., 22 to 24 dBm).

[0105] According to various embodiments, the maximum transmit power of each transmit path (UE Tx MAX power (PcMax)) configured in the electronic device 101 may be different because the RFFE of each transmit path is different, and may also be different because the length of each transmit path is different. Hereinafter, reference will be made to Figure 4E Describe an example in which the maximum transmit power (UE Tx MAX power (PcMax)) of each transmit path configured in the electronic device 101 is different for each transmit path.

[0106] Figure 4E is a block diagram of an electronic device according to various embodiments. Refer to Figure 4E, According to various embodiments, the electronic device 101 may support communication with multiple communication networks. For example, the electronic device 101 may support a first communication network and a second communication network, and the first communication network and the second communication network may be the same communication network or 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.

[0107] According to various embodiments, the frequency bands of the signals transmitted through the first RFFE 431 and the signals transmitted through the second RFFE 432 may be the same, similar, or different. For example, the frequency band of the signals transmitted through the first RFFE 431 may be the N41 frequency band (2.6 GHz) which is a frequency band of the 5G network, and the frequency band of the signals transmitted through the second RFFE 431 may be the B41 frequency band (2.6 GHz) which is a frequency band of the LTE network. In this case, the first RFFE 431 and the second RFFE 432 may process signals of the same or similar frequency bands, 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.

[0108] According to various embodiments, the first RFFE 431 may be designed to process signals with a wider frequency bandwidth than the second RFFE 432. For example, the first RFFE 431 may be designed to process a frequency bandwidth up to 100 MHz, while the second RFFE 432 may be designed to process a frequency bandwidth up to 60 MHz.

[0109] According to various embodiments, the first RFFE 431 may further include additional components different from those of the second RFFE 432 (e.g., a single-pole double-throw (SPDT) switch for transmitting sounding reference signals (SRS), a filter for preventing and / or reducing interference between WIFI signals in a frequency band similar to that of 5G signals, a component for separating WIFI signals from received signals, a duplexer for separating different 5G band signals) to process signals suitable for the characteristics of the 5G network or support multi-band. Refer to Figure 4E, the first RFFE 431 may include a front-end module (FEM) 460 and a first single-pole double-throw (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 FEM 460 may be connected to a PA envelope tracking IC (ET IC) 464 to amplify the power according to the amplitude of the signal, thereby reducing current consumption and heat generation and improving the performance of the PA 461.

[0110] According to various embodiments, the first SPDT switch 470 may selectively output a sounding reference signal (SRS) (e.g., an N41 band SRS signal) and a first communication network signal (e.g., an N41 band signal) sent from the RFIC 410 through the FEM 460 to send them through the first antenna 441. For example, due to the components configured inside the first SPDT switch 470 and the first RFFE 431 for SRS transmission and the components added for 5G signal processing or multi-band signal processing, the attenuation (e.g., path loss) generated according to the processing of the transmitted signal may be greater than that of the second RFFE 432. For example, even if the communication processor 260 controls the power amplifiers of the first RFFE 431 and the second RFFE 432 such that signals of the same power are transmitted, the amplitude of the signal transmitted through the first antenna module 441 may be smaller than the amplitude of the signal transmitted through the second antenna module 442 because the path loss of the first RFFE 431 is greater than the path loss of the second RFFE 432.

[0111] Referring to Table 1 below, according to different transmission paths within the same N41 band (or B41 band), the maximum power of each transmission path may be different.

[0114] As shown in Table 1, the path loss of the upper N41 path transmitted through the first RFFE 431 is 2 dB or more greater than the path loss of the lower N41 path transmitted through the second RFFE 432.

[0115] Return to reference Figure 4A, according to various embodiments, even if the first RFFE 431 transmits signals of the same amplitude, the power actually radiated from the first antenna 441 via the switch 450 and the power actually radiated from the second antenna 442 via the switch 450 may be different. In addition, regarding the maximum transmit power that the electronic device 410 can transmit, the maximum transmit power when the signal is transmitted to the first antenna 441 through the first RFFE 431, the maximum transmit power when the signal is transmitted to the second antenna 442 through the first RFFE 431, the maximum transmit power when the signal is transmitted to the first antenna 441 through the second RFFE 432, and the maximum transmit power when the signal is transmitted to the second antenna 442 through the second RFFE 432 may be different from each other.

[0116] According to various embodiments, when the first communication network transmits and receives signals in the N41 frequency band of the 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 mid / high frequency band LTE signals (e.g., B2 or B41 frequency band signals). At least one of the first RFFE 431 and the second RFFE 432 may be configured in the form of a power amplitude module (PAMiD) including a duplexer.

[0117] According to various embodiments, the frequency band of the signal transmitted through the first RFFE 431 and the frequency band of the 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 the N41 frequency band (2.6 GHz) which is a high frequency band frequency of the 5G network, and the frequency band of the signal transmitted through the second RFFE 432 may be the B41 frequency band (2.6 GHz) which is a high frequency band frequency of the LTE network. In this case, the first RFFE 431 and the second RFFE 432 may process signals of the same or similar frequency bands, 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.

[0118] According to another embodiment, the frequency band of the signal transmitted through the first RFFE 431 may be the N41 frequency band (2.6 GHz) which is a high frequency band frequency of the 5G network, and the frequency band of the signal transmitted through the second RFFE 432 may be the B2 frequency band (1.9 GHz) which is a mid frequency band frequency of the LTE network.

[0119] According to various embodiments, the second RFFE 432 may be designed to be suitable for processing mid / high-band LTE signals (e.g., B2 or B41 band signals), such that the first RFFE 431 and the electronic device 101 may operate as various types of EN-DC. For example, the first RFFE 431 and the second RFFE 432 may be combined to operate as an EN-DC of B2-N41 or an EN-DC of B41-N41.

[0120] According to various embodiments, as shown in and below, a predefined maximum power reduction (MPR) or an additional maximum power reduction (A-MPR) may be further considered to configure the maximum transmit power (UE Tx MAX power) of each transmit path configured in the electronic device 101.

[0121] [Table 2]

[0122]

[0123]

[0124] [Table 3]

[0125]

[0126] Referring to and , the maximum transmit power of each antenna transmit path may be configured differently according to different path losses. and show the MPR defined according to the 3GPP standard. shows the MPR of power class (PC) 3, while shows the MPR of power class 2. According to various embodiments, even in the same channel environment, the MPR backoff may vary according to the modulation type or bandwidth (BW). According to various embodiments, when the electronic device 101 receives power class 3 in Table 2 from the base station as the power class, the maximum powers of the first transmit path (e.g., the N41 transmit path at the upper end of the electronic device 101) and the second transmit path (e.g., the N41 transmit path at the lower end of the electronic device 101) may be determined differently, as shown in Table 4 below.

[0127] [Table 4]

[0128]

[0129]

[0130] Referring to , for example, even in the same state where the maximum transmit power (P-MAX power) received by the electronic device 101 from the base station is 24 dBm corresponding to PC3, when applying the path loss described in and the MPR backoff described in <Tables 2> and , the maximum transmit power of each transmit path can be configured differently according to each modulation scheme or bandwidth.

[0131] For example, regarding the maximum transmit power of the upper N41 transmit path (the first transmit path) in , when considering that the maximum transmit power configured in the electronic device due to the path loss in is 24.5 dBm and the maximum transmit power corresponding to PC3 received from the base station is 24 dBm, the maximum transmit power of the corresponding path identified can be the minimum value of 24 dBm, as Figure 8 shown. At this time, as noted from , when calculating the minimum value of the P-MAX power and the UE Tx MAX power by applying the MPR backoff of <Tables 2> and to the UE Tx MAX power, the minimum value is 22.5 dBm in CP OFDM internal 16QAM, 21.5 dBm in CP OFDM external 16QAM, 21 dBm in CP OFDM 64QAM, and 18 dBm in CP OFDM 256QAM.

[0132] Furthermore, for example, regarding the maximum transmit power of the lower N41 transmit path (the second transmit path) in , when considering that the maximum transmit power configured in the electronic device due to the path loss in is 27 dBm and the maximum transmit power corresponding to PC3 received from the base station is 24 dBm, the maximum transmit power of the corresponding path identified can be the minimum value of 24 dBm, as Figure 8 shown. At this time, as noted from , when calculating the minimum value of the P-MAX power and the UE Tx MAX power by applying the MPR backoff of <Tables 2> and to the UE Tx MAX power, the minimum value is 24 dBm in CP OFDM internal 16QAM, 24 dBm in CP OFDM external 16QAM, 23.5 dBm in CP OFDM 64QAM, and 20.5 dBm in CP OFDM 256QAM.

[0133] Referring to Table 4, the application of MPR varies according to the modulation scheme or bandwidth. Therefore, the UE Tx MAX power changes, and ultimately, according to Figure 8The differences in the maximum transmit power calculable for each transmit path may vary. For example, the difference in the maximum transmit power for each transmit path may be 1.5 dB in 16QAM within CP OFDM, 2.5 dB in 16QAM outside CP OFDM, 1.5 dB in CP OFDM 64QAM, and 1.5 dB in CP OFDM 256QAM.

[0134] According to various embodiments, when determining the maximum transmit power, the maximum transmit power for a SAR event configured in consideration of SAR backoff may be further considered. For example, referring to below, when SAR backoff is applied according to each type of SAR event, the maximum transmit power for each path may vary. For example, when a sensor detects a SAR event such as a grip event or a proximity event, the electronic device 101 may apply the SAR backoff corresponding to each SAR event to the maximum transmit power.

[0135] [Table 5]

[0136]

[0137] Referring to , when a proximity event occurs, the SAR backoff for the proximity event is applied to the upper N41 transmit path (first transmit path) so that the maximum transmit power can be determined to be 19 dBm, and when a grip event occurs, the SAR backoff for the grip event is applied to the lower N41 transmit path (second transmit path) so that the maximum transmit power can be determined to be 21 dBm. For example, when a user grips the electronic device 101 with a hand, the touch sensor may detect the grip event, and when the user approaches the electronic device 101 for a phone call, the proximity sensor may detect the proximity event. The event detection results of each sensor may be passed to the communication processor 260 by the processor 120.

[0138] Hereinafter, according to various embodiments, reference will be made to Figure 4A a specific example will be described in which the electronic device 101 (e.g., the communication processor 260) determines whether to change the transmit path in consideration of the difference between the received signal strength and the maximum transmit power (Tx maximum power) for each transmit path determined as described above. For ease of description, it is assumed that Figure 4A the first RFFE 431 in is connected to the first antenna tuning circuit 441a and the first antenna 441. In addition, it is assumed that the switching threshold for changing the transmit path is 1 dB. For example, when an unconfigured different transmit path has a performance 1 dB or better than the currently configured transmit path (e.g., when the received signal strength is greater), the currently configured transmit path may be switched.

[0139] According to various embodiments, an electronic device 101 (e.g., a communication processor 260) may identify whether a transmission path of a transmitted signal has changed (or whether an antenna has been switched) during each configured time period (e.g., 640 ms).

[0140] Referring Figure 4A , the RSRP (first RSRP) of the PRx signal received through the first antenna 441, the first antenna tuning circuit 441a, the switch 450, and the first RFFE 431 may be assumed to be -90 dBm, and the RSRP (second RSRP) of the DRx signal received through the second antenna 442, the second antenna tuning circuit 442a, the switch 450, and the second RFFE 432 may be assumed to be -88 dBm, but is not limited thereto.

[0141] When switching the transmission path by only considering the intensity difference between received signals (e.g., second RSRP - first RSRP), in the above example, a switch of the transmission path may occur because the intensity difference between received signals (RSRP difference (Diff)) is 2 dB (2 dBm - 1 dBm) and the switching threshold is 1 dB. For example, the communication processor 260 may control the switch 450 such that the transmitted signal is transmitted to the RFIC 410, the first RFFE 431, the switch 450, the second antenna tuning circuit 442a, and the second antenna 442, or is transmitted to the RFIC 410, the second RFFE 432, the switch 450, the second antenna tuning circuit 442a, and the second antenna 442.

[0142] According to various embodiments, when calculating the maximum transmission power of each transmission path by considering the path loss of each transmission path as described above, the maximum transmissible power of the transmission path through the first RFFE 431, the switch 450, the first antenna tuning circuit 441a, and the first antenna 441 (referred to as the first transmission path for convenience of description) may be determined to be 27 dBm, and the maximum transmissible power of the transmission path through the second RFFE 432, the switch 450, the second antenna tuning circuit 442a, and the second antenna 442 (referred to as the second transmission path for convenience of explanation) may be determined to be 24.5 dBm. In this case, whether to change the transmission path or switch the transmission antenna may be determined according to the following formula.

[0143] 1. First RSRP = -90 dBm, maximum transmission power of the first transmission path = 27 dBm

[0144] 2. Second RSRP = -88 dBm, maximum transmission power of the second transmission path = 24.5 dBm

[0145] 3. Switching threshold = 1 dB

[0146] 4. The intensity difference between the received signals = Second RSRP - First RSRP = -88 - (-90) = 2 dB

[0147] 5. The maximum transmit power difference = The maximum transmit power of the second transmit path - The maximum transmit power of the first transmit path = 24.5 - 27 = -2.5 dB

[0148] 6. The intensity difference between the received signals + The maximum transmit power difference = 2 dB - 2.5 dB = -0.5 dB

[0149] As a result of the above calculations, the value obtained by considering the intensity difference between the received signals and the maximum transmit power difference is -0.5 dB of the handover threshold that does not exceed 1 dB, enabling the current transmit path to be maintained without changing the transmit path. For example, when only comparing the differences between the received signals, the second RSRP received through a different transmit path is 2 dB or more greater than the first RSRP received through the transmit path that is transmitting the current transmit signal. However, when transmitting the transmit signal through the path that receives the second RSRP, the power output is 2.5 dB lower. Therefore, it may be more advantageous not to change the transmit path in this state.

[0150] According to various embodiments, in the case of operating in CP OFDM and 64QAM, when calculating the maximum transmit power of each transmit path by further considering the MPR as described above, the maximum transmit power of the transmit path through the first RFFE 431, switch 450, first antenna tuning circuit 441a, and first antenna 441 (referred to as the first transmit path for convenience of description) can be determined to be 23.5 dBm, and the maximum transmit power of the transmit path through the second RFFE 432, switch 450, second antenna tuning circuit 442a, and second antenna 442 (referred to as the second transmit path for convenience of description) can be determined to be 21 dBm. In this case, the following formula can be used to determine whether to change the transmit path or switch the transmit antenna.

[0151] 1. First RSRP = -90 dBm, the maximum transmit power of the first transmit path = 23.5 dBm

[0152] 2. Second RSRP = -88 dBm, the maximum transmit power of the second transmit path = 21 dBm

[0153] 3. Handover threshold = 1 dB

[0154] 4. The intensity difference between the received signals = Second RSRP - First RSRP = -88 - (-90) = 2 dB

[0155] 5. Maximum transmission power difference = Maximum transmission power of the second transmission path - Maximum transmission power of the first transmission path = 21 - 23.5 = -2.5 dB

[0156] 6. Intensity difference between received signals + Maximum transmission power difference = 2 dB - 2.5 dB = -0.5 dB

[0157] As a result of the above calculations, the value obtained by considering the intensity difference between received signals and the maximum transmission power difference is -0.5 dB of the handover threshold that does not exceed 1 dB, enabling the current transmission path to be maintained without changing the transmission path. For example, when only comparing the differences between received signals, the second RSRP received through a different transmission path is 2 dB or more greater than the first RSRP received through the transmission path that transmits the current transmission signal. However, due to path loss and the application of MPR, when transmitting the transmission signal through the path that receives the second RSRP, the power output is 2.5 dB lower. Therefore, it may be more advantageous not to change the transmission path in this state.

[0158] According to various embodiments, when calculating the maximum transmission power of each transmission path by further considering SAR backoff according to the SAR event as described above, the maximum transmitable power of the transmission path through the first RFFE 431, switch 450, first antenna tuning circuit 441a, and first antenna 441 (referred to as the first transmission path for ease of explanation) can be determined to be 21 dBm because of the SAR backoff caused by the gripping event, and the maximum transmitable power of the transmission path through the second RFFE 432, switch 450, second antenna tuning circuit 442a, and second antenna 442 (referred to as the second transmission path for ease of explanation) can be determined to be 24 dBm because no SAR backoff is applied. In this case, the formula below can be used to determine whether to change the transmission path or switch the transmission antenna. In the following example, the first RSRP and the second RSRP are -88 dBm, so it can be assumed that they are the same.

[0159] 1. First RSRP = -88 dBm, Maximum transmission power of the first transmission path = 21 dBm

[0160] 2. Second RSRP = -88 dBm, Maximum transmission power of the second transmission path = 24 dBm

[0161] 3. Handover threshold = 1 dB

[0162] 4. Intensity difference between received signals = Second RSRP - First RSRP = -88 - (-88) = 0 dB

[0163] 5. Maximum transmission power difference = Maximum transmission power of the second transmission path - Maximum transmission power of the first transmission path = 24 - 21 = 3 dB

[0164] 6. Intensity difference between received signals + Maximum transmission power difference = 0 dB + 3 dB = 3 dB

[0165] As a result of the above calculations, the value obtained by considering the difference in the intensity of the received signals and the difference in the maximum transmission power is 3 dB, which exceeds the switching threshold of 1 dB. Therefore, the transmission path can be changed from the first transmission path to the second transmission path. For example, when only comparing the differences in the intensity of the received signals, since the intensity of the received signals is the same (e.g., in the case of the same electric field), there is no need to change the transmission path. However, due to the SAR event caused by the grip in the current transmitted signal, according to the application of SAR back-off, the power output is 3 dB lower. Therefore, the transmission path can be changed to another transmission path where no SAR event occurs.

[0166] As another example, the SAR event can be detected by a proximity sensor on the second transmission path. According to various embodiments, when calculating the maximum transmission power of each transmission path by further considering SAR back-off according to the SAR event as described above, the maximum transmitable power of the first transmission path through the first RFFE 431, switch 450, first antenna tuning circuit 441a, and first antenna 441 can be determined to be 24 dBm because no SAR back-off is applied, and the maximum transmitable power of the second transmission path through the second RFFE 432, switch 450, second antenna tuning circuit 442a, and second antenna 442 can be determined to be 19 dBm because SAR back-off is applied according to the proximity event detected by the proximity sensor. In this case, the formula below can be used to determine whether to change the transmission path or switch the transmit antenna. In the following example, the first RSRP can be assumed to be -91 dBm and the second RSRP can be assumed to be -88 dBm.

[0167] 1. First RSRP = -91 dBm, Maximum transmission power of the first transmission path = 24 dBm

[0168] 2. Second RSRP = -88 dBm, Maximum transmission power of the second transmission path = 19 dBm

[0169] 3. Switching threshold = 1 dB

[0170] 4. Intensity difference between received signals = Second RSRP - First RSRP = -91 - (-88) = 3 dB

[0171] 5. Maximum transmission power difference = Maximum transmission power of the second transmission path - Maximum transmission power of the first transmission path = 19 - 24 = -5 dB

[0172] 6. Intensity difference between received signals + Maximum transmission power difference = 3 dB - 5 dB = -2 dB

[0173] As a result of the above calculations, the value obtained by considering the intensity difference between received signals and the maximum transmission power difference is -2 dB of the handover threshold that does not exceed 1 dB, such that the current transmission path can be maintained without changing the transmission path. For example, when only comparing the differences between received signals, the second RSRP received through a different transmission path is 3 dB or more greater than the first RSRP received through the transmission path that transmits the current transmission signal. However, when transmitting the transmission signal through the path that receives the second RSRP, due to applying SAR fallback through a grip event, the power output is 5 dB lower. Therefore, it may be more advantageous not to change the transmission path in this state.

[0174] In the above, examples of determining whether to change the transmission path by considering the intensity difference between received signals and the difference in maximum transmission power have been described according to various embodiments. Hereinafter, examples of determining whether to change the transmission path by further considering transmit / receive imbalance in addition to the intensity difference between received signals will be described according to various embodiments.

[0175] According to various embodiments, when determining whether to change the transmission path, in addition to the received signal strength, the electronic device 101 (e.g., the communication processor 260) may also consider a configuration related to an imbalance state (or an imbalance value indicating the degree of imbalance) between the transmission signal and the received signal configured for each of the plurality of antennas.

[0176] Reference Figure 4A , each of the first antenna tuning circuit 441a and the second antenna tuning circuit 442a may include at least one impedance tuning circuit or at least one aperture tuning circuit. The electronic device 101 (e.g., the communication processor 260) may adjust the configured value of the first antenna tuning circuit 441a or the second antenna tuning circuit 442a to change the frequency characteristics of the signals transmitted and received through the respective antennas 441, 442. Detailed examples of each of the antenna tuning circuits will be described later Figure 5A , Figure 5B , Figure 5C or Figure 5D in the description.

[0177] According to various embodiments, the electronic device 101 (e.g., the communication processor 260) may control the antenna tuning circuit (e.g., Figure 4AThe configuration of each of the first antenna tuning circuit 441a or the second antenna tuning circuit 442a). The transmission performance and reception performance of signals transmitted and received through the respective antennas 441 and 442 can vary depending on the configuration. For example, depending on the configuration of the antenna tuning circuit, the transmission performance can be configured to be superior to the reception performance, or the reception performance can be configured to be superior to the transmission performance. According to various embodiments, a value (imbalance value) indicating the degree of imbalance representing the performance difference between the transmitted signal and the received signal can be measured differently according to the configuration related to the unbalanced state (e.g., each configuration mode related to the unbalanced state), as shown in below.

[0178] [Table 6]

[0179]

[0180] Referring to , according to various embodiments, when the antenna tuner configuration mode is configured as the default, a value (hereinafter referred to as the "imbalance value" for convenience) indicating the degree of imbalance between the transmitted signal and the received signal can be configured as a fixed value, such as "1". According to various embodiments, when the configuration related to the unbalanced state (e.g., the antenna tuner configuration mode) is configured as a transmit-only configuration (e.g., a transmit-only mode (Tx-only mode)), a receive-only configuration (e.g., a receive-only mode (Rx-only mode)), and a transmit / receive balance configuration (e.g., a transmit / receive balance mode (Tx / Rx balance mode)), the imbalance value can vary depending on the corresponding mode configuration, as shown in above. According to various embodiments, when the electronic device 101 (e.g., the communication processor 260) configures the antenna tuner according to the Tx-only mode, the imbalance value is 5, which can indicate that the transmission performance of the corresponding antenna is 5 dB better than the reception performance. When the electronic device 101 (e.g., the communication processor 260) configures the antenna tuner according to the Rx-only mode, the imbalance value is -2, indicating that the reception performance of the corresponding antenna is 2 dB better than the transmission performance. When the electronic device 101 (e.g., the communication processor 260) configures the antenna tuner according to the Tx / Rx balance mode, the imbalance value is 2, indicating that the transmission performance of the corresponding antenna is 2 dB better than the reception performance.

[0181] For example, when the electronic device 101 (e.g., the communication processor 260) configures the antenna tuning circuit configuration mode (antenna tuner configuration mode) as a specific mode (e.g., a transmit-only mode, a receive-only mode, a transmit / receive balance mode), the imbalance value indicating the difference between the transmission performance and the reception performance can change in real time according to the current channel state.

[0182] In various embodiments described below, a method for determining whether to change a transmission path by an electronic device 101 (e.g., a communication processor 260) will be described in detail by further considering an imbalance value that changes in real time according to each antenna tuner configuration mode, in addition to the difference in the intensity of received signals.

[0183] According to various embodiments, each specific mode may operate according to a predetermined (e.g., specified) condition. For example, the transmit-only mode may be configured to further improve the transmission performance of a corresponding antenna when the power of a transmission signal transmitted through the corresponding antenna is greater than or equal to a first threshold (e.g., 10 dBm to 15 dBm) and the electric field of a received signal (e.g., SNR) is greater than or equal to a second threshold (e.g., 5 dB). According to the configuration, the reception performance of the corresponding antenna may be relatively reduced. For example, when the configuration mode is configured as the transmit-only mode, the electronic device 101 (e.g., the communication processor 260) may compare the transmission performances of a plurality of tuner configuration values (e.g., 141 configuration values) that can be configured in the corresponding antenna tuning circuit to perform a configuration such that an operation is performed using the tuner configuration value that provides the optimal transmission performance.

[0184] According to various embodiments, the receive-only mode may be configured to further improve the transmission performance of a corresponding antenna when the power of a transmission signal transmitted through the corresponding antenna is less than or equal to a first threshold (e.g., 10 dBm to 15 dBm) and the electric field of a received signal (e.g., SNR) is less than or equal to a second threshold (e.g., 5 dB). According to the configuration, the reception performance of the corresponding antenna may be relatively reduced. For example, when the configuration mode is configured as the receive-only mode, the electronic device 101 (e.g., the communication processor 260) may compare the reception performances of a plurality of tuner configuration values (e.g., 141 configuration values) that can be configured in the corresponding antenna tuning circuit to perform a configuration such that an operation is performed using the tuner configuration value that provides the optimal reception performance.

[0185] According to various embodiments, the transmit / receive balance mode may be configured to improve both the transmit and receive performance of a corresponding antenna when the power of a transmit signal transmitted through the corresponding antenna is equal to or greater than a first threshold (e.g., 10 dBm to 15 dBm) and the electric field of a received signal (e.g., SNR) is less than or equal to a second threshold (e.g., 5 dB). For example, when the configuration mode is configured as the transmit / receive balance mode, the electronic device 101 (e.g., the communication processor 260) may compare the transmit performance and the receive performance of a plurality of tuner configuration values (e.g., 141 configuration values) that may be configured in the corresponding antenna tuning circuit, and may configure the tuner configuration value providing the optimal receive performance to perform the configuration such that an operation is performed using the tuner configuration value providing the optimal receive performance among the tuner configuration values within the range where the transmit performance is configured. For example, compared with the tuner configuration value having the optimal transmit performance with respect to a plurality of configurable tuner configuration values (e.g., 141 configuration values), the tuner configuration value providing the optimal receive performance may be selected from among the tuner configuration values in a range where the transmit performance is as low as 1 dB.

[0186] As in the above example, the antenna tuner configuration mode may be changed according to the power of the transmit signal or the electric field of the received signal. In addition, even in each antenna tuner configuration mode, the tuner configuration value may be changed in real time according to the channel environment. Accordingly, the transmit / receive imbalance value in each antenna tuner configuration mode may be changed.

[0187] Hereinafter, according to various embodiments, reference will be made to Figure 4A a specific example in which the electronic device 101 (e.g., the communication processor 260) determines whether to change a transmit path by considering the intensity difference between received signals and / or the transmit / receive imbalance value of an antenna determined as described above. For convenience of description, it is assumed that Figure 4A the first RFFE 431 in is connected to the first antenna tuning circuit 441a and the first antenna 441. In addition, it is assumed that the switching threshold for changing the transmit path is 1 dB. For example, when a different transmit path that is not configured has a performance that is 1 dB or more better than the currently configured transmit path (e.g., when the received signal strength is greater), the currently configured transmit path may be switched to the different transmit path.

[0188] According to various embodiments, the electronic device 101 (e.g., the communication processor 260) may identify whether the transmit path of a transmit signal is changed (or whether the antenna is switched) in each configured time period (e.g., 640 ms).

[0189] According to various embodiments, an electronic device 101 (e.g., a communication processor 260) may be configured in a transmit-only mode in , and the identified imbalance value may be 5 dB. For example, the antenna tuner configuration mode may be configured in a transmit-only mode. When the tuner configuration is adjusted according to the transmit-only mode configuration, the transmit performance may be superior to the receive performance by 5 dB, and even in the same antenna tuner configuration mode, the identified imbalance value may vary according to the frequency band or channel environment at each measurement.

[0190] In an embodiment described later, the threshold for switching the transmit path is assumed to be 1 dB. Refer to Figure 4A , the RSRP (first RSRP) of the PRx signal received through the first antenna 441, the first antenna tuning circuit 441a, the switch 450, and the first RFFE 431 may be assumed to be -91 dBm, and the RSRP (second RSRP) of the DRx signal received through the second antenna 442, the second antenna tuning circuit 442a, the switch 450, and the second RFFE 432 may be assumed to be -88 dBm, but it is not limited thereto.

[0191] When switching the transmit path is considered only based on the intensity difference between received signals (e.g., second RSRP - first RSRP), the transmit path may be switched because in the above example, the intensity difference of the received signals (RSRP difference (Diff)) is 3 dB, and the switching threshold is 1. In addition, when the default value of 1 dB is applied as the imbalance value to the intensity difference of the received signals, RSRP difference (3 dB) - imbalance value (1 dB) = 2 dB, which exceeds the threshold of 1 dB for switching the transmit path, so switching may occur.

[0192] According to various embodiments, in a case where the identified imbalance value is 5 dB because the current antenna tuner configuration mode is configured in a transmit-only mode, when the 5 dB imbalance value is applied to the intensity difference between received signals, RSRP difference (3 dB) - imbalance value (5 dB) = -2 dB, which does not exceed the threshold of 1 dB for switching the transmit path, so the transmit path may not be switched. For example, in the case of the above example, the electric field corresponding to the first antenna 441 has not deteriorated, but since the first antenna 441 operates in a transmit-only mode while the actual electric field is in the same state, the performance of the received signal has deteriorated. Therefore, switching to the second antenna 442 may not occur.

[0193] As another example, the RSRP (first RSRP) of the PRx signal received through the first antenna 441, the first antenna tuning circuit 441a, the switch 450, and the first RFFE 431 may be assumed to be -9 dBm, and the RSRP (second RSRP) of the DRx signal received through the second antenna 442, the second antenna tuning circuit 442a, the switch 450, and the second RFFE 432 may be assumed to be equal to -90 dBm. When switching the transmission path by only considering the intensity difference between the received signals (e.g., second RSRP - first RSRP), in the above example, the intensity difference (RSRP difference) between the received signals is 0 dB, and since the switching threshold is 1, the transmission path switching may not occur. In addition, when a default value of 1 dB is applied as the imbalance value to the intensity difference between the received signals, the RSRP difference (0 dB) - the imbalance value (1 dB) = -1 dB, which does not exceed 1 dB as the threshold for switching the transmission path, and thus, the transmission path switching may not occur.

[0194] According to various embodiments, in a case where the imbalance value is -2 dB because the current antenna tuner configuration mode is configured as a receive-only mode, when the imbalance value of -2 dB is applied to the intensity difference between the received signals, the RSRP difference (0 dB) - the imbalance value (-2 dB) = 2 dB, which exceeds 1 dB as the threshold for switching the transmission path, and thus, the transmission path switching may occur. For example, due to nearby base stations having the same frequency, a phenomenon where the RSRP is good but the SNR deteriorates may occur. In this case, the electronic device 101 may operate in the receive-only mode to improve the performance of the received signal. As in the above example, when the performance of the transmitted signal is configured to be worse than the performance of the received signal through the configuration of the receive-only mode, the loss occurring in the antenna may be reduced by switching the transmission path, which may be advantageous for improving the performance of the transmitted signal and reducing current consumption.

[0195] Hereinafter, reference will be made to Figure 4B 、 Figure 4C and Figure 4D to describe an electronic device according to various embodiments. Since the method for determining the transmission path described above with reference to Figure 4A may be applied to the embodiments to be described later in the same or similar manner, the repeated description will be omitted.

[0196] Figure 4B is a block diagram of an electronic device according to various embodiments.

[0197] Referring to Figure 4B an electronic device according to various embodiments (e.g., Figure 1The electronic device 101) 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 441a, a second antenna tuning circuit 442a, or a third antenna tuning circuit 443a. For example, the first RFFE 431 may be placed at the upper end of the housing of the electronic device 101, and the second RFFE 432 may be placed at the lower end of the housing of the electronic device 101. However, various embodiments of the present disclosure are not limited to the arrangement positions.

[0198] According to various embodiments, during transmission, the RFIC 410 may convert the baseband signal generated by the communication processor 260 into a radio frequency (RF) signal to be used in a communication network. For example, the RFIC 410 may transmit the RF signal to be used in the communication network to the first antenna 441 or the second antenna 442 through the first RFFE 431 and the switch 450.

[0199] According to various embodiments, the transmission path for transmission from the RFIC 410 to the first antenna 441 through the first RFFE 431 and the switch 450 may be referred to as the "first antenna transmission path (Ant Tx 1)". The transmission path for transmission from the RFIC 410 to the second antenna 442 through the first RFFE 431 and the switch 450 may be referred to as the "second antenna transmission path (Ant Tx 2)". According to various embodiments, due to differences in the length of each transmission path and / or the components placed on the corresponding transmission path, the transmission paths of the two antennas may have different path losses. In addition, since the antennas corresponding to the respective antenna transmission paths (e.g., the first antenna 441, the second antenna 442) are placed at different positions on the electronic device 101, different antenna losses may occur. In addition, the first antenna tuning circuit 441a may be connected to the front end of the first antenna 441, and the second antenna tuning circuit 442a may be connected to the front end of the second antenna 442. The communication processor 260 may adjust the configuration of the first antenna tuning circuit 441a and the configuration of the second antenna tuning circuit 442a, thereby tuning the signals (e.g., transmission signal (Tx)) transmitted and received through each connected antenna and the signals (e.g., received signal (Rx)). Details thereof will be described later with reference to Figure 5A 、 Figure 5B 、 Figure 5C and Figure 5D for a detailed description.

[0200] According to various embodiments, the communication processor 260 may control the switch 450 to perform configuration such that the first RFFE 431 is connected to the first antenna tuning circuit 441a and the first antenna 441. At this time, 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 441a, and the antenna 441.

[0201] According to various embodiments, the first antenna 441 may be configured as a primary Rx (PRx) antenna, and the third antenna 443 may be configured 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. For example, the signal received through the first antenna 441 is a PRx signal and may be transmitted to the communication processor 260 through the first antenna tuning circuit 441a, the switch 450, the first RFFE 431, and the RFIC 410. In addition, the signal received through the third antenna 443 is a DRx signal and may be transmitted to the communication processor 260 through the third antenna tuning circuit 443a, the second RFFE 432, and the RFIC 410.

[0202] According to various embodiments, the communication processor 260 may control the switch 450 to perform configuration such that the first RFFE 431 is connected to the second antenna tuning circuit 442a and the second antenna 442. At this time, 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 442a, and the second antenna 442.

[0203] According to various embodiments, the second antenna 442 may be configured as a primary Rx (PRx) antenna, and the third antenna 443 may be configured as a diversity Rx (Drx) antenna. 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 is a PRx signal and may be transmitted to the communication processor 260 through the second antenna tuning circuit 442a, the switch 450, the first RFFE 431, and the RFIC 410. In addition, the signal received through the third antenna 443 is a DRx signal and may be transmitted to the communication processor 260 through the third antenna tuning circuit 443a, the second RFFE 432, and the RFIC 410.

[0204] According to various embodiments, the communication processor 260 may configure a transmission path corresponding to an antenna capable of radiating a transmission signal (Tx) with maximum power. For example, as Figure 4BAs shown, when transmitting a transmission signal from the electronic device 101 including multiple antenna transmission paths, the optimal antenna transmission path can be configured by considering path loss and the channel environment (e.g., received signal strength) corresponding to each antenna (e.g., the first antenna 441, the second antenna 442, the third antenna 443). The communication processor 260 can determine the optimal antenna transmission path and control the switch 450 so that the transmission signal is transmitted through the determined optimal antenna transmission path.

[0205] According to various embodiments, the electronic device 101 (e.g., the communication processor 260) can consider the difference between the received signal strength and the maximum transmit power (Tx max power) of each transmission path described above with reference to Figure 4A to determine whether to change the transmission path, and since specific examples can be the same or similar to the examples in Figure 4A , the detailed description thereof will be omitted.

[0206] According to various embodiments, when determining whether to change the transmission path, in addition to the received signal strength, the electronic device 101 (e.g., the communication processor 260) can further consider the transmit / receive imbalance value determined according to the configuration value configured for the antenna tuning circuit to determine whether to change the transmission path, as described above with reference to Figure 4A and since specific examples can be the same or similar to the examples in Figure 4A , the detailed description thereof will be omitted.

[0207] With reference to Figure 4A and Figure 4B The method described for configuring the transmission path can be equivalently or similarly applied to the electronic device 101 including 4 antennas or 5 antennas, as shown in Figure 4C and 4D described later. In the following description, the description overlapping with the method described in Figure 4A and Figure 4B will be omitted.

[0208] Figure 4C and 4D are block diagrams of an electronic device according to various embodiments. According to various embodiments, Figure 4C is an embodiment in which the electronic device 101 has two transmission paths based on RFFE and operates as a stand-alone (SA) or non-stand-alone (NSA). Figure 4D illustrates an embodiment in which the electronic device 101 has three transmission paths based on RFFE and operates as an NSA.

[0209] Referring to Figure 4C , the electronic device according to various embodiments (e.g., Figure 1The electronic device 101) 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 fourth antenna 444, a first switch 451, or a second switch 452. For example, the first RFFE 431 may be placed at the upper end of the housing of the electronic device 101, and the second RFFE 432 may be placed at the lower end of the housing of the electronic device 101. However, various embodiments are not limited to the above arrangement positions.

[0210] According to various embodiments, during transmission, the RFIC 410 may convert a baseband signal generated by the communication processor 260 into a radio frequency (RF) signal to be used in a first communication network. For example, the RFIC 410 may transmit the RF signal to be 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. In addition, the RFIC 410 may transmit the RF signal to be used in the first communication network to the third antenna 443 or the fourth antenna 444 through the first RFFE 431, the first switch 451, and the second switch 452.

[0211] According to various embodiments, during transmission, the RFIC 410 may convert a baseband signal generated by the communication processor 260 into a radio frequency (RF) signal to be used in a second communication network. For example, the RFIC 410 may transmit the RF signal to be 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. In addition, the RFIC 410 may transmit the RF signal to be 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.

[0212] According to various embodiments, a transmission path for transmission from the RFIC 410 to the first antenna 441 through the first RFFE 431 and the first switch 451 may be referred to as a “first antenna transmission path (Ant Tx1)”. A transmission path for transmission from the RFIC 410 to the second antenna 442 through the first RFFE 431 and the first switch 451 may be referred to as a “second antenna transmission path (Ant Tx 2)”. A transmission path for transmission from the RFIC 410 to the third antenna 443 through the first RFFE 431, the first switch 451, and the second switch 452 may be referred to as a “third antenna transmission path (Ant Tx 3)”. A transmission path for transmission from the RFIC 410 to the fourth antenna 444 through the first RFFE 431, the first switch 451, and the second switch 452 may be referred to as a “fourth antenna transmission path (Ant Tx 4)”. According to various embodiments, due to differences in the length of each transmission path and components placed on the corresponding transmission path, the transmission paths of the four antennas may have different path losses.

[0213] According to various embodiments, when a transmission signal is transmitted from the electronic device 101 including multiple antenna transmission paths, the electronic device 101 (eg, the communication processor 260) may consider the received signal strength and the above-mentioned reference signal strength. Figure 4A The difference between the maximum transmittable power (Tx maximum power) of each transmission path determined is used to determine whether to change the transmission path. Figure 4A The examples are the same or similar, so their detailed description will be omitted.

[0214] According to various embodiments, when determining whether to change the transmission path, in addition to the received signal strength, the electronic device 101 (eg, the communication processor 260) may further consider the above reference Figure 4A The configuration value of the antenna tuning circuit configuration described above determines the transmit / receive imbalance value to determine whether to change the transmit path. Figure 4A The examples are the same or similar, so their detailed description will be omitted.

[0215] Figure 4D is a block diagram of an electronic device according to various embodiments.

[0216] refer to Figure 4D , according to various embodiments of the electronic device (eg, Figure 1 The electronic device 101) may include a processor 120, a communication processor 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.

[0217] According to various embodiments, during transmission, the RFIC 410 may convert the baseband signal generated by the communication processor 260 into a radio frequency (RF) signal to be used in the first communication network or the second communication network. For example, the RFIC 410 may send the RF signal to be 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. In addition, the RFIC 410 may send the RF signal to be used in the first communication network to the third antenna 443 or the fourth antenna 444 through the first RFFE 431, the first switch 451, and the second switch 452.

[0218] According to various embodiments, during transmission, the RFIC 410 may convert the baseband signal generated by the communication processor 260 into a radio frequency (RF) signal to be used in the second communication network. For example, the RFIC 410 may send the RF signal to be 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. In addition, the RFIC 410 may send the RF signal to be 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.

[0219] According to various embodiments, during transmission, the RFIC 410 may convert the baseband signal generated by the communication processor 260 into a radio frequency (RF) signal to be used in the third communication network. For example, the RFIC 410 may send the RF signal to be used in the third communication network to the fifth antenna 445 through the third RFEE 433.

[0220] According to various embodiments, during reception, an RF signal can be obtained from a first communication network via a first antenna 441 or a second antenna 442, and the RF signal can be preprocessed via a first RFFE 431 through a first switch 451. The RFIC 410 can convert the RF signal preprocessed via the first RFFE 431 into a baseband signal such that the signal can be processed by the communication processor 260. In addition, the RF signal can be obtained from a second communication network via a third antenna 443 or a fourth antenna 444 and preprocessed via a second RFFE 432 through a second switch 452. The RFIC 410 can convert the RF signal preprocessed via the second RFFE 432 into a baseband signal such that the signal can be processed by the communication processor 260. In addition, the RF signal can be obtained from a third communication network via a fifth antenna 445, and the RF signal can be preprocessed via a third RFFE 433. The RFIC 410 can convert the RF signal preprocessed via the third RFFE 433 into a baseband signal such that the signal can be processed by the communication processor 260.

[0221] According to various embodiments, the first communication network, the second communication network, and the third communication network can be the same or different communication networks. For example, the first communication network can be a 5G network, and the second communication network and the third communication network can be legacy networks (e.g., LTE networks). According to various embodiments, even if the second communication network and the third communication network are the same LTE network, the second communication network and the third communication network can support communication in different frequency bands. For example, the second communication network can be a communication network that transmits and receives high-band LTE (e.g., B41 band) signals, and the fourth communication network can 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 can be from 0.6 GHz to 1.0 GHz, the mid-band frequency can be from 1.7 GHz to 2.2 GHz, and the high-band frequency can be from 2.3 GHz to 3.7 GHz. However, for better understanding, this is classified as an example, and various embodiments are not limited to a specific frequency range.

[0222] According to various embodiments, when the first communication network transmits and receives signals in the N41 band of the 5G network, the first RFFE 431 can be designed to be suitable for processing signals corresponding to the 5G network, the second RFFE 432 can be designed to be suitable for processing high-band LTE signals (e.g., B41 band signals), and the third RFFE 433 can be designed to be suitable for processing low-band LTE signals (e.g., B5 band signals). At least one of the second RFFE 432 and the third RFFE 433 can be configured in the form of a power amplitude module including a duplexer (PAMiD).

[0223] According to various embodiments, the frequency bands of the signals transmitted through the first RFFE 431 and the signals 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 the N41 frequency 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 431 may be the B41 frequency 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 may process signals of the same or similar frequency bands, but the first RFFE 431 may be designed to enable signal processing suitable for the characteristics of a 5G network, and the second RFFE 432 may be designed to enable signal processing suitable for the characteristics of an LTE network.

[0224] According to various embodiments, the first RFFE 431 may be designed to process signals of a wider frequency bandwidth than the second RFFE 432. For example, the first RFFE 431 may be designed to process a frequency bandwidth up to 100 MHz, while the second RFFE 432 may be designed to process a frequency bandwidth up to 60 MHz.

[0225] According to various embodiments, the first RFFE 431 may further include additional components different from the second RFFE 432 (e.g., a single-pole double-throw (SPDT) switch for transmitting a sounding reference signal (SRS) signal, a filter for preventing and / or reducing interference between WIFI signals in a frequency band similar to a 5G signal, a component for separating a WIFI signal from a received signal, a duplexer for separating different 5G band signals) for signal processing suitable for the characteristics of a 5G network or multi-band support. Since the first RFFE 431 further includes additional components compared to the second RFFE 432, the attenuation (e.g., path loss) generated according to the processing of the transmitted signal may be greater. For example, even if the RFIC 410 controls the power amplifiers of the first RFFE 431 and the second RFFE 432 to transmit signals of the same power, the path loss of the first RFFE 431 is greater than the path loss of the second RFFE 432, and the amplitude of the signal transmitted through the first antenna module 441 may be smaller than the amplitude of the signal transmitted through the second antenna module 442.

[0226] According to various embodiments, when transmitting a transmission signal from the electronic device 101 including a plurality of antenna transmission paths, the electronic device 101 (e.g., the communication processor 260) may further consider the received signal strength and as referred to above Figure 4AThe difference between the maximum transmit power (Tx maximum power) of each determined transmit path is used to determine whether to change the transmit path. Since specific examples may be the same as or similar to the examples in Figure 4A they will be omitted from detailed description.

[0227] According to various embodiments, when determining whether to change the transmit path, in addition to the received signal strength, the electronic device 101 (e.g., the communication processor 260) may further consider the transmit / receive imbalance value determined according to the configuration value for the antenna tuning circuit configuration described above with reference to Figure 4A to determine whether to change the transmit path. Since specific examples may be the same as or similar to the examples in Figure 4A they will be omitted from detailed description.

[0228] Figures 5A to 5D FIG. shows an antenna tuning circuit according to various embodiments.

[0229] Referring to Figure 5A , the antenna tuning circuit 440a according to various embodiments (e.g., Figure 4A the first antenna tuning circuit 441a, the second antenna tuning circuit 442a, and the third antenna tuning circuit 443a) may include at least one impedance tuning circuit 510 and at least one aperture tuning circuit 520. The second antenna tuning circuit 442a may be implemented the same as the first antenna tuning circuit 441a, but may also be implemented differently. The impedance tuning circuit 510 according to various embodiments may be configured to perform impedance matching with the network under the control of at least one processor (e.g., the processor 120, the communication processors 212, 214, and / or the integrated communication processor 260). The aperture tuning circuit 520 according to various embodiments may change the structure of the antenna by turning on / off switches under the control of at least one processor. Figure 5B FIG. shows an exemplary circuit diagram for illustrating the impedance tuning circuit 510. Figure 5C An exemplary circuit diagram for explaining the aperture tuning circuit 520 is shown in

[0230] Referring to Figure 5B, according to various embodiments, the impedance tuning circuit 510 may include at least one variable capacitor 541, a first switch 542, a second switch 543, a third switch 544, and a fourth switch 545. According to various embodiments, the number of the variable capacitor 541, the first switch 542, the second switch 543, the third switch 544, and the fourth switch 545 may be changed. According to various embodiments, at least one variable capacitor 541, the first switch 542, the second switch 543, the third switch 544, and the fourth switch 545 may be implemented on a single chip. The variable capacitor 541 according to various embodiments may have, for example, 16 values (e.g., capacitance values). According to various embodiments, the number of capacitance values of the variable capacitor 541 may be changed. In this case, the impedance tuning circuit 510 according to various embodiments may have a total of 256 (16 (possible values that the variable capacitor may have) × 16 (number of possible cases of combinations having four switches)) configurable values. (e.g., impedance values). The variable capacitor 541 according to each embodiment may be electrically connected to the first switch 542. According to various embodiments, one end of each of the second switch 543, the third switch 544, and the fourth switch 545 may be grounded.

[0231] Reference Figure 5C , according to various embodiments, the aperture tuning circuit 520 may include a fifth switch 522, a sixth switch 524, a seventh switch 526, and an eighth switch 528. According to various embodiments, the fifth switch 522 may be connected to a first end (RF1, 522a). According to various embodiments, the sixth switch 524 may be connected to a second end (RF2, 524a). According to various embodiments, the seventh switch 526 may be connected to a third end (RF3, 526a). According to various embodiments, the eighth switch 528 may be connected to a fourth end (RF4, 528a). According to various embodiments, the number of switches included in the aperture tuning circuit 520 may be changed. According to various embodiments, the fifth switch 522, the sixth switch 524, the seventh switch 526, and the eighth switch 528 may be implemented on a single chip. According to various embodiments, the aperture tuning circuit 520 may have a total of 16 cases of on / off combinations of switches (e.g., the fifth switch 522, the sixth switch 524, the seventh switch 526, and the eighth switch 528). Therefore, the tuning circuit 250 according to various embodiments may have a total of 4096 (i.e., 256 × 16) antenna configurations.

[0232] As Figure 5B and Figure 5CAs shown, the resonant characteristics of the connected antenna (e.g., the resonant frequency of the antenna) can be changed according to the change in the on / off state of the switches included in the antenna tuning circuit 440a (e.g., the impedance tuning circuit 510 and / or the aperture tuning circuit 520). The combination of the on / off states of the switches can be referred to as the antenna configuration, and the antenna resonant characteristics can be changed, or the antenna efficiency can be changed according to the antenna configuration.

[0233] According to various embodiments, as Figure 5D shown, the impedance tuning circuit 510 can be connected to the conduction point 571. The conduction point 571 can be connected to, for example, an RFFE (e.g., Figure 4A and Figure 4B the first RFFE 431 and the second RFFE 432 in), and can be connected to the duplexer of the RFFE. The conduction point 571 can indicate the power rail (or power channel) to which the RFFE and the antenna tuning circuit are connected. The impedance tuning circuit 510 can be connected to the antenna 530, and the aperture tuning circuits 520a and 520b can be connected to the power rail connecting the impedance tuning circuit 510 and the antenna 530.

[0234] According to various embodiments, the electronic device 101 (e.g., the communication processor 260) can change the configuration value of the antenna tuning circuit 440a according to the antenna tuner configuration mode as described above. As described above, the electronic device 101 can perform control such that the on / off state of the switches (e.g., the impedance tuning circuit 510 and / or the aperture tuning circuit 520) included in the antenna tuning circuit 440a is changed according to the change in the configuration value of the antenna tuning circuit 440a. According to various embodiments, when determining whether to change the transmission path, the electronic device 101 can further consider the transmit / receive imbalance value determined according to the change in the configuration value of the antenna tuning circuit 440a.

[0244] Figure 9 is a flowchart showing a method for operating an electronic device according to various embodiments. The electronic device (e.g., Figure 1 the electronic device 101 in

[0245] Referring to Figure 9, According to various embodiments, for each configured time period (e.g., 640 ms) or when a specific event occurs (e.g., a SAR event occurs or the electric field situation changes rapidly, or signaling from a base station), the electronic device 101 (e.g., the communication processor 260) may identify whether the transmission path of the transmitted signal has changed (or whether the antenna has switched). For example, in operation 910, when the time point for identifying whether the transmission path has changed (e.g., at the time point for identifying antenna switching) has arrived (910 - Yes), the electronic device 101 may, in operation 920, identify the received signal strength of each reception path. For example, the electronic device 101 (e.g., the communication processor 260) may identify information related to the received signal strength of each reception path (e.g., reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), received signal code power (RSCP), signal-to-noise ratio (SNR), or signal-to-interference-plus-noise ratio (SINR)). According to various embodiments, the electronic device 101 may determine whether to change the transmission path based at least on the strength difference between received signals.

[0246] According to various embodiments, in operation 930, the electronic device 101 may identify the maximum transmit power of each transmission path. As described above in Figure 8 , at least one of the maximum transmit power for a SAR event configured in response to each SAR event (SAR EVENT MAX power), the maximum transmit power received from each communication network (e.g., a base station) (P-MAX power (PeMax)), the maximum transmit power of each transmission path configured in the electronic device 101 (UE Tx MAX power (PcMax)), and / or a specific absorption rate (SAR) fallback may be considered to configure the maximum transmit power of each transmission path. For example, the maximum transmit power may be determined as the minimum value among the above-mentioned multiple maximum transmit powers (e.g., P-MAX power, UE TxMAX power, SAR EVENT MAX power), but is not limited thereto.

[0247] According to various embodiments, in operation 940, the electronic device 101 may identify the optimal transmission path based on the received signal strength of each reception path and the maximum transmit power of each transmission path. For example, the electronic device 101 may determine the optimal transmission path by calculating the difference in strength between received signals of multiple reception paths and the difference in maximum transmit power of each transmission path. Since specific embodiments of determining the optimal transmission path based on the received signal strength of each reception path and the maximum transmit power of each transmission path have been described in detail in the description of Figure 4A , the detailed description thereof will be omitted.

[0248] According to various embodiments, when the best transmission path identified in operation 950 is the current transmission path (950 - Yes), in operation 960, the electronic device 101 may maintain the currently configured transmission path. When the best transmission path identified in operation 950 is not the current transmission path (950 - No), in operation 970, the electronic device 101 may perform a configuration such that the currently configured transmission path is changed to the identified best transmission path. For example, the electronic device 101 may configure the transmission path of the transmission signal to the best transmission path by controlling the RFIC (e.g., the RFIC 410 in Figure 4A or a switch (e.g., the switch 450 in Figure 4A ).

[0249] When the identification of the best transmission path and the change of the transmission path are completed, in operation 910, the electronic device may again identify whether the antenna switching identification time has arrived. According to the above operations, the electronic device 101 may identify whether the transmission path of the transmission signal has changed in each configured time period (e.g., 640 ms).

[0250] Figure 10 FIG. is a flowchart illustrating a method for operating an electronic device according to various embodiments. The electronic device (e.g., the electronic device 101 in Figure 1 ) may include a communication processor 260, at least one radio frequency integrated circuit (RFIC) 410 connected to the communication processor, and a plurality of antennas 441, 442, 443, 444, 445, 661, 662, 663, 664, each antenna being connected to at least one RFIC through at least one radio frequency front - end (RFFE) circuit 431, 432, 433, 634 to transmit a corresponding signal to at least one communication network.

[0251] Referring to Figure 10, According to various embodiments, for each configured time period (e.g., 640 ms) or when a specific event occurs (e.g., when a SAR event occurs or when the electric field situation changes rapidly, or signaling from a base station), the electronic device 101 (e.g., the communication processor 260 of the electronic device) may identify whether the transmission path of the transmitted signal has changed (or whether the antenna has switched). For example, in operation 1010, when the time point for identifying whether the transmission path has changed (e.g., at the time point for identifying antenna switching) has arrived (1010 - Yes), the electronic device 101 may, in operation 1020, identify the received signal strength of each reception path. For example, the electronic device 101 (e.g., the communication processor 260) may identify information related to the received signal strength of each reception path (e.g., reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), received signal code power (RSCP), signal-to-noise ratio (SNR), or signal-to-interference-plus-noise ratio (SINR)). According to various embodiments, the electronic device 101 may determine whether to change the transmission path based at least on the strength difference between the received signals.

[0252] According to various embodiments, in operation 1030, the electronic device 101 may identify the tuner configuration value of each antenna. For example, the electronic device 101 may identify the tuner configuration value configured for the antenna corresponding to the current transmission path. According to various embodiments, the tuner configuration value for the antenna configuration may be determined according to a configuration related to the imbalance state between the transmitted signal and the received signal or a specific antenna tuner configuration mode (e.g., transmit-only mode, receive-only mode, transmit / receive balance mode). The electronic device 101 may identify the transmit / receive imbalance value according to the tuner configuration value.

[0253] According to various embodiments, in operation 1040, the electronic device 101 may determine the optimal transmission path based on the transmit / receive imbalance value determined according to the received signal strength of each reception path and the tuner configuration value of each antenna. For example, the electronic device 101 may determine the optimal transmission path by calculating the strength difference between the received signals of multiple reception paths and the transmit / receive imbalance value. Since specific embodiments of determining the optimal transmission path based on the received signal strength of each reception path and the transmit / receive imbalance value have been described in detail in the Figure 4A description, the detailed description thereof will be omitted.

[0254] According to various embodiments, when the best transmission path identified in operation 1050 is the current transmission path (1050 - Yes), in operation 1060, the electronic device 101 may maintain the currently configured transmission path. When the best transmission path identified in operation 1050 is not the current transmission path (1050 - No), in operation 1070, the electronic device 101 may perform a configuration such that the currently configured transmission path is changed to the identified best transmission path. For example, the electronic device 101 may configure the transmission path of the transmission signal to the best transmission path by controlling an RFIC (e.g., the RFIC 410 in Figure 4A ), or a switch (e.g., the switch 450 in Figure 4A ).

[0255] When the identification of the best transmission path and the change of the transmission path are completed, in operation 1010, the electronic device may identify again whether the antenna switching identification time has arrived. According to the above operations, the electronic device 101 may identify whether the transmission path of the transmission signal has changed in each configured time period (e.g., 640 ms).

[0256] Figure 11 is a flowchart illustrating a method for operating an electronic device according to various embodiments. The electronic device (e.g., the electronic device 101 in Figure 1 ) may include a communication processor 260, at least one radio frequency integrated circuit (RFIC) 410 connected to the communication processor, and a plurality of antennas 441, 442, 443, 444, 445, 661, 662, 663, 664, each antenna being connected to at least one RFIC through at least one radio frequency front-end (RFFE) circuit 431, 432, 433, 631, 632 to transmit a corresponding signal to at least one communication network.

[0257] Referring to Figure 11, According to various embodiments, for each configured time period (e.g., 640 ms) or when a specific event occurs (e.g., when a SAR event occurs or when the electric field situation changes rapidly, or signaling from a base station), the electronic device 101 (e.g., the communication processor 260 of the electronic device) may identify whether the transmission path of the transmitted signal has changed (or whether the antenna has switched). For example, in operation 1110, when the time point for identifying whether the transmission path has changed (e.g., at the time point for identifying antenna switching) has arrived (1010 - Yes), the electronic device 101 may identify the received signal strength of each receiving path in operation 1120. For example, the electronic device 101 (e.g., the communication processor 260) may identify information related to the received signal strength of each receiving path (e.g., reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), received signal code power (RSCP), signal-to-noise ratio (SNR), or signal-to-interference-plus-noise ratio (SINR)). According to various embodiments, the electronic device 101 may determine whether to change the transmission path based at least on the intensity difference between received signals.

[0258] According to various embodiments, the electronic device 101 may identify in operation 1130 whether a SAR event has occurred. For example, the electronic device 101 may identify a SAR event, such as a gripping event or a proximity event, by using a touch sensor or a proximity sensor.

[0259] According to various embodiments, when the electronic device 101 determines in operation 1130 that a SAR event has occurred (1130 - Yes), the electronic device 101 may identify the optimal transmission path in operation 1140 based on the received signal strength of each receiving path and the SAR back-off power of the SAR event. For example, the electronic device 101 may determine the optimal transmission path by calculating the maximum transmit power that reflects the intensity difference between received signals of multiple receiving paths and the SAR back-off of each transmission path. According to various embodiments, when the electronic device 101 determines in operation 1130 that no SAR event has occurred (1130 - No), in operation 1150, the electronic device 101 may identify the optimal transmission path based on the received signal strength of each receiving path. The operation of identifying that a SAR event has occurred has been described as being performed after identifying the signal strength, but a SAR event that occurs before identifying the signal strength is not excluded.

[0260] According to various embodiments, when the best transmission path identified in operation 1160 is the current transmission path (1160 - Yes), in operation 1170, the electronic device 101 may maintain the currently configured transmission path. When the best transmission path identified in operation 1160 is not the current transmission path (1160 - No), in operation 1180, the electronic device 101 may perform a configuration such that the currently configured transmission path is changed to the identified best transmission path. For example, the electronic device 101 may configure the transmission path of the transmission signal to the best transmission path by controlling the RFIC (e.g., Figure 4A the RFIC 410 therein) or a switch (e.g., Figure 4A the switch 450 therein).

[0261] When the identification of the best transmission path and the change of the transmission path are completed, in operation 1110, the electronic device may identify again whether the antenna switching identification time has arrived. According to the above operations, the electronic device 101 may identify whether the transmission path of the transmission signal has changed in each configuration period (e.g., 640 ms).
