[0002] In order to send a signal from an electronic device to a communication network (e.g., a base station), data generated from a processor or a communication processor in the electronic device can be processed by a radio frequency integrated circuit (RFIC) and a radio frequency front end (hereinafter referred to as "RFFE") circuit, for ease of description, and then sent to the outside of the electronic device through an antenna.

[0003] According to an embodiment, an electronic device supporting multiple communication networks may provide multiple transmission (Tx) paths for signal transmission for each communication network.

In addition, each RFFE circuit may be connected to one or more antennas, and accordingly, the multiple transmission paths may be divided into multiple antenna transmission paths (antenna Tx paths) corresponding to the multiple antennas.

In addition, different antenna losses may occur because the antennas corresponding to the antenna transmission paths are placed at different positions on the electronic device.

[0044] The sensor module 176 may detect an operating state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a user's state) outside the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. Depending on an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an accelerometer, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.

[0045] The interface 177 may support one or more designated protocols for direct (e.g., wired) or wireless coupling of the electronic device 101 to an external electronic device (e.g., the electronic device 102). According to an embodiment, the interface 177 may include, for example, a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.

The communication module 190 may include one or more communication processors that can operate 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). A corresponding one of these communication modules can communicate via a first network 198 (e.g., a short-range communication network such as Bluetooth TM , Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a remote 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 local area network (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 may be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 may use subscriber information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the subscriber identification module 196 to identify or authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199).

[0052] The wireless communication module 192 can support 5G networks after 4G networks and next-generation communication technologies (e.g., new radio (NR) access technology).

According to another embodiment, the fourth RFIC 228 may be omitted or included as part of the third RFIC 226.

[0058] The first communication processor 212 may establish a communication channel of a frequency band to be used for wireless communication with the first cellular network 292, or may support traditional network communication via the established communication channel. According to an embodiment, the first cellular network may be a traditional network including a second generation (2G), a third generation (3G), a fourth generation (4G), or a long term evolution (LTE) network. The second CP 214 may establish a communication channel corresponding to a specified frequency band (e.g., from about 6 GHz to about 60 GHz) in a frequency band to be used for wireless communication with the second cellular network 294, or may support fifth generation (5G) network communication via the established communication channel. According to an embodiment, the second cellular network 294 may be a 5G network defined by the third generation partnership project (3GPP). In addition, according to an embodiment, the first CP 212 or the second CP 214 may establish a communication channel corresponding to another specified frequency band (e.g., about 6 GHz or lower) in a frequency band to be used for wireless communication with the second cellular network 294, or may support fifth generation (5G) network communication via the established communication channel.

[0059] The first communication processor 212 can perform data transmission / reception with the second communication processor 214. For example, data classified as transmitted via the second cellular network 294 can be changed to be transmitted via the first cellular network 292. In this case, the first communication processor 212 can receive transmission data from the second communication processor 214. For example, the first communication processor 212 can send / receive data to / from the second communication processor 214 via the inter-processor interface 213. The inter-processor interface 213 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 bus fast (PCIe) interface, but is not limited to a specific type. The first communication processor 212 and the second communication processor 214 can use, for example, a shared memory to exchange packet data information and control information. The first communication processor 212 can send / receive various pieces of information such as sensing information, output strength information, or resource block (RB) allocation information to / from the second communication processor 214.

[0060] According to an embodiment, the first communication processor 212 may not be directly connected to the second communication processor 214. In this case, the first communication processor 212 may send / receive data to / from the second communication processor 214 via the processor 120 (e.g., an application processor). For example, the first communication processor 212 and the second communication processor 214 may send / receive data to / from the processor 120 (e.g., an application processor) via an HS-UART interface or a PCIe interface, but the type of interface is not limited thereto. The first communication processor 212 and the second communication processor 214 may exchange control information and packet data information with the processor 120 (e.g., an application processor) using a shared memory.

[0061] According to an embodiment, the first communication processor 212 and the second communication processor 214 may be implemented in a single chip or a single package. According to an embodiment, the first CP 212 or the second CP 214 together with the processor 120, the auxiliary processor 123 or the communication module 190 may be formed in a single chip or a single package. Figure 2b As shown, the integrated communication processor 260 can support all functions for communicating with the first cellular network 292 and the second cellular network 294.

[0062] As described above, at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the integrated communication processor 260 may be implemented as a single chip or a single package. In this case, the single chip or the single package may include a memory (or storage means) storing instructions and a processing circuit (or operating circuit, but the term is not limited thereto) for executing the instructions, the instructions causing at least some operations to be performed according to the embodiment.

[0063] When transmitting, the first RFIC 222 can convert the baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal with a frequency range of about 700 MHz to about 3 GHz used by the first cellular network 292 (e.g., a legacy network). When receiving, the RF signal can be obtained from the first network 292 (e.g., a legacy network) through an antenna (e.g., the first antenna module 242) and pre-processed via an RFFE (e.g., the first RFFE 232). The first RFIC 222 can convert the pre-processed RF signal into a baseband signal that can be processed by the first communication processor 212.

[0064] When transmitting, the second RFIC 224 may convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 into a 6G or lower frequency band (e.g., about 6 GHz or lower) RF signal (hereinafter, "5G 6 or lower RF signal") used by the second cellular network 294 (e.g., 5G network). When receiving, the 5G 6 or lower RF signal may be obtained from the second cellular network 294 (e.g., 5G network) through an antenna (e.g., the second antenna module 244), and the 5G 6 or lower RF signal may be pre-processed via an RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the pre-processed 5G 6 or lower RF signal into a baseband signal, which may be processed by the respective processors of the first communication processor 212 and the second communication processor 214.

[0065] The third RFIC 226 may convert a baseband signal generated by the second communication processor 214 into a 5G 6 or higher frequency band (e.g., about 6 GHz to about 60 GHz) RF signal (hereinafter, “5G 6 or higher RF signal”) to be used by the second cellular network 294 (e.g., 5G network). Upon reception, the 5G 6 or higher RF signal may be obtained from the second cellular network 294 (e.g., 5G network) through an antenna (e.g., antenna 248) and the 5G 6 or higher RF signal may be pre-processed via the third RFFE 236. The third RFIC 226 may convert the pre-processed 5G 6 or higher RF signal into a baseband signal that may be processed by the second communication processor 214. According to an embodiment, the third RFFE 236 may be formed as part of the third RFIC 226.

[0066] According to an embodiment, the electronic device 101 may include a fourth RFIC 228 that is separate from the third RFIC 226 or is at least a part of the third RFIC 226. In this case, the fourth RFIC 228 may convert the baseband signal generated by the second communication processor 214 into an intermediate frequency band (e.g., from about 9 GHz to about 11 GHz) RF signal (hereinafter, "IF signal") and transmit the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G 6 or higher RF signal. When receiving, the 5G 6 or higher RF signal may be received from the second cellular network 294 (e.g., 5G network) through an antenna (e.g., antenna 248) and converted into an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal into a baseband signal that can be processed by the second communication processor 214.

[0067] According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least a portion of a single chip or a single package. Figure 2a or Figure 2b When the first RFIC 222 and the second RFIC 224 in the embodiment are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC is connected to the first RFFE 232 and the second RFFE 234 to convert the baseband signal into a signal of 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 a portion 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 another antenna module to process a multi-band RF signal.

[0068] According to an embodiment, the third RFIC 226 and the antenna 248 may be placed on the same substrate to form a third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be placed on a first substrate (e.g., a main printed circuit board (PCB)). In this case, the third RFIC 226 and the antenna 248 may be placed on one region (e.g., bottom) and another region (e.g., top) of a second substrate (e.g., a sub-PCB) provided separately from the first substrate, respectively, thereby forming the third antenna module 246. Placing the third RFIC 226 and the antenna 248 on the same substrate may shorten the length of the transmission line therebetween. This may reduce the loss (e.g., attenuation) of high frequency band (e.g., from about 6 GHz to about 60 GHz) signals for 5G network communication due to the transmission line. Therefore, the electronic device 101 may enhance the communication quality with the second network 294 (e.g., 5G network).

[0069] According to an embodiment, the antenna 248 may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC 226 may include a plurality of phase shifters 238 corresponding to the plurality of antenna elements as part of the third RFFE 236. During transmission, the plurality of phase shifters 238 may change the phase of the 5G 6 or higher RF signal to be sent to the outside of the electronic device 101 (e.g., a 5G network base station) via their respective corresponding antenna elements. During reception, the plurality of phase shifters 238 may change the phase of the 5G6 or higher RF signal received from the outside via their respective corresponding antenna elements to the same or substantially the same phase. This enables transmission or reception between the electronic device 101 and the outside via beamforming.

[0070] The second cellular network 294 (e.g., 5G network) can operate independently of the first cellular network 292 (e.g., legacy network) (e.g., as a standalone (SA)), or in conjunction with the first cellular network 292 (e.g., legacy network) (e.g., as a non-standalone (NSA)). For example, the 5G network may include access networks (e.g., 5G access networks (RANs)) but lack any core network (e.g., next generation core (NGC)). In this case, the electronic device 101 can access the core network of the legacy network (e.g., evolution core (NGC)) after accessing the 5G network access network. Grouping The memory 230 may be used to access an external network (e.g., the Internet) under the control of the core (EPC). Protocol information for communicating with a traditional network (e.g., LTE protocol information) or protocol information for communicating with a 5G network (e.g., new radio (NR) protocol information) may be stored in the memory 230 and accessed by other components (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

[0071] Figure 3a is a view showing a change of a transmission antenna according to an embodiment.

[0072] According to an embodiment, the RF circuit 300 of the electronic device 101 may include an RFIC 301 (e.g., a first RFIC 222, a second RFIC 224, a third RFIC 226, and / or a fourth RFIC 228) and / or a plurality of PAs 303 and 313. It will be appreciated by those skilled in the art that the plurality of PAs 303 and 313 may be included in at least one RFFE (e.g., a first RFFE 232, a second RFFE 234, and / or a third RFFE 236). The first antenna 305 may be connected to the first PA 303, and the second antenna 315 may be connected to the second PA 313. For example, an RF signal may be provided to the first antenna 305 through the first PA 303. The RF path from the first PA 303 to the first antenna 305 may be referred to as a first RF path. For example, an RF signal may be provided to the second antenna 315 through the second PA 313. The RF path from the second antenna 315 through the second PA 313 may be referred to as a second RF path. An RF path may mean, for example, a path to which an RF signal is applied, and may mean at least some of a plurality of hardware associated with the path.

[0073] According to an embodiment, the electronic device 101 (eg, Figure 2a a first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2bThe integrated communication processor 260 of the electronic device 101 may support the function of changing the transmission antenna. For example, the electronic device 101 may determine that the RF signal is provided through the first RF path. In this case, the electronic device 101 may provide the RF signal to the first PA 303. Therefore, the RF signal amplified by the PA 303 may be provided to the first antenna 305. For example, the electronic device 101 may identify that the conditions for changing the RF path are met. For example, when the first indicator indicating at least one performance corresponding to the first RF path is worse than the second indicator indicating at least one performance corresponding to the second RF path (or when the first indicator and the second indicator meet the preset conditions), the electronic device 101 may change the RF path from the first RF path to the second RF path. There is no limitation on the preset conditions associated with the first indicator and the second indicator. The electronic device 101 (e.g., the communication processor (e.g., the first communication processor 212, the second communication processor 214, or the integrated communication processor 260)) may change the RF path from the first RF path to the second RF path by controlling at least a portion of the RF circuit 300. Accordingly, the RF signal may be provided to the second PA 313. The RF signal amplified by the second PA 313 may be provided to the second antenna 315. As described above, the transmission antenna for the RF signal may be changed from the first antenna 305 to the second antenna 315. This may be referred to as transmission antenna hopping. For example, when supporting dual connectivity (e.g., EN-DC but not limited thereto), the electronic device 101 may include a PA (e.g., PA 303 and 313) supporting the same frequency band. In this case, the electronic device 101 may use multiple PAs 303 and 313 to perform transmission antenna hopping. For example, PAs 303 and 313 may support mid-band (MB) / high-band (HB). In this case, the electronic device 101 may perform transmission antenna hopping on the RF signal of MB / HB.

[0074] Figure 3b is a view showing a change of a transmission antenna according to an embodiment.

[0075] According to an embodiment, the RF circuit 310 of the electronic device 101 may include an RFIC 301 (e.g., a first RFIC 222, a second RFIC 224, a third RFIC 226, and / or a fourth RFIC 228), a PA 321, and / or a switch 323. The switch 323 may selectively connect the first antenna 325 or the second antenna 327 to the PA 321. For example, the switch 323 may operate based on the control of the communication processor 212, 214, and / or 260 and / or the RFIC 301, but is not limited thereto. It will be understood by those skilled in the art that the switch 323 may be implemented as an SPnT, but the type is not limited. For example, in Figure 3b In an embodiment of the present invention, the switch 323 can be controlled so that the RF signal is provided to the first antenna 325 through the PA 321. This can be referred to as a first RF path. For example, the switch 323 can be controlled so that the RF signal is provided to the second antenna 327 through the PA 321. This can be referred to as a second RF path.

[0076] According to an embodiment, the electronic device 101 (e.g., the communication processor 212, 214 and / or 260) may support a function of changing a transmission antenna. For example, the electronic device 101 may determine that an RF signal is provided through a first RF path. In this case, the electronic device 101 may control the switch 323 to provide an RF signal to the first PA 321. Therefore, the RF signal amplified by the first PA 321 may be provided to the first antenna 325. For example, the electronic device 101 may identify that a condition for changing the RF path is met. For example, when a first indicator indicating at least one performance corresponding to the first RF path is worse than a second indicator indicating at least one performance corresponding to the second RF path (or when the first indicator and the second indicator meet a preset condition), the electronic device 101 may change the RF path from the first RF path to the second RF path.

[0077] In one example, the condition associated with the first indicator and the second indicator may be a condition associated with a first reception strength (which may be RSRP, but not limited thereto) corresponding to the first antenna 325 and a second reception strength corresponding to the second antenna 327. The electronic device 101 may be configured to measure the reception strengths corresponding to the antennas 325 and 327 within a specified period (e.g., 640 ms, but not limited thereto). The electronic device 101 may identify a reception strength difference (e.g., RSRP diffcurrent), which is the difference between the first reception strength and the second reception strength at the current time. In addition, the electronic device 101 may identify MTPL diff, which is the difference between the first maximum transmission power level (MTPL) corresponding to the first RF path and the second MTPL corresponding to the second RF path. In the example condition, when the sum of the reception strength difference (RSRP diffcurrent) and the MTPL diff at the current time is a first threshold (referred to as a high threshold for ease of description) or greater, the electronic device 101 may identify that the antenna change condition is met. In an example condition, when the degree of change in reception strength is greater than a threshold degree of change (eg, when a sudden reception strength change is detected), the electronic device 101 may recognize that the antenna change condition is satisfied.

[0078] In the example, the electronic device 101 can identify the average reception strength difference (which is called the RSRP average value). The average value can be calculated, for example, twice or more times, and the number of times is unlimited. In the example condition, when the sum of the average reception strength difference (RSRP average value) and the MTPL is a second threshold (for ease of description, referred to as a low threshold) or greater, the electronic device 101 can identify that the antenna change condition is met. The second threshold may be less than the first threshold, but is not limited to this. In the example condition, when continuous reception strength differences occur, the electronic device 101 can also identify that the antenna change condition is met. It will be understood by those of ordinary skill in the art that the above-mentioned antenna change conditions are merely exemplary, and whether the antenna change conditions are met can be determined based on the respective reception strengths of the antennas, the average value of the differences, the MTPL and / or the MTPL difference, and whether the antenna change conditions are met can also be determined based on replacing the above-mentioned parameters or at least one parameter added.

[0079] For example, upon recognizing that the antenna change condition is satisfied, the electronic device 101 (e.g., the communication processor (e.g., the first communication processor 212, the second communication processor 214, or the integrated communication processor 260)) can change the RF path from the first RF path to the second RF path by controlling the switch 323. Therefore, the RF signal amplified by the PA 321, which was previously provided to the first antenna 325, can be provided to the second antenna 327. As described above, the transmission antenna for the RF signal can be changed from the first antenna 325 to the second antenna 327. This can be referred to as transmission antenna switching.

[0080] According to various embodiments, the electronic device 101 can be combined with Figure 3a Transmit antenna hopping or combining described Figure 3b In the present disclosure, the operation of changing the transmission antenna may be performed, for example, by transmission antenna hopping or by transmission antenna switching.

[0081] Figure 4a is a flowchart illustrating an operating method of an electronic device according to an embodiment. Figure 4b describe Figure 4a Embodiment of the invention. Figure 4b is a view showing a housing of an electronic device according to an embodiment.

[0082] refer to Figure 4a In operation 401, the electronic device 101 (eg, Figure 2a a first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2b The integrated communication processor 260 of the electronic device 101 can identify that the folded state of the electronic device 101 is the open state. For example, the communication processor 212, 214 and / or 260 can receive information associated with the folded state of the processor 120 (e.g., the application processor). For example, referring to Figure 4b , the electronic device 101 may include a first housing 431 and a second housing 432. The first housing 431 and the second housing 432 may be connected by a hinge structure (eg, Figure 4cThe hinge structure 458 of the first shell 431 is rotated. For example, when one surface of the first shell 431 and one surface of the second shell 432 face substantially the same direction, the folded state of the electronic device 101 can be referred to as an open state. For example, when one surface of the first shell 431 and one surface of the second shell 432 substantially face each other, the folded state of the electronic device 101 can be referred to as a closed state. The electronic device 101 can identify whether the folded state of the electronic device 101 is an open state, a closed state, or a semi-closed state. For example, the processor 120 can identify the folded state based on sensing data from at least one sensor (e.g., a Hall sensor) for determining whether it is folded. The processor 120 can transmit the identified folded state information to the communication processors 212, 214, and / or 260, and the communication processors 212, 214, and / or 260 can identify the folded state of the electronic device 101 based on the received information.

[0083] Return to reference Figure 4a In operation 403, the electronic device 101 may control the RF circuit (eg, Figure 3a The RF circuit 300 or Figure 3b The RF circuit 310 of the embodiment of the present invention is used to provide a first RF signal corresponding to the first frequency band to a first antenna among the plurality of antennas. For example, an antenna that can be used for each folding state can be set in the available antennas corresponding to the first frequency band. For example, the antenna corresponding to the folding state being the open state among the available antennas corresponding to the first frequency band can be the first antenna. For example, the antenna corresponding to the folding state being the closed state among the available antennas corresponding to the first frequency band can be the second antenna. The antenna corresponding to the open state and the antenna corresponding to the closed state are described below.

[0084] According to an embodiment, in operation 405, the electronic device 101 may recognize that the folding state of the electronic device 101 is changed from an open state to a closed state. The electronic device 101 may recognize that the folding state of the electronic device 101 is a closed state. For example, as described above, the processor 120 may recognize that the folding state is changed from an open state to a closed state based on information from at least one sensor. The processor 120 may provide information indicating that the folding state is a closed state to the communication processors 212, 214, and / or 260. The communication processors 212, 214, and / or 260 may recognize that the folding state of the electronic device 101 is changed from an open state to a closed state based on information from the processor 120.

[0085] According to an embodiment, in operation 407, the electronic device 101 may recognize that the electronic device 101 is held by a user. Figure 4b, the electronic device 101 may include at least one holding sensor 441 and 442. For example, the processor 120 may identify whether the electronic device 101 is held based on information sensed by at least one holding sensor 441 and 442. In the example, when it is identified that all holding sensors 441 and 442 identify holding, it can be determined that the electronic device 101 is held, but this is exemplary and not restrictive. The processor 120 may provide information for identifying whether it is held to the communication processor 212, 214, and / or 260. The communication processor 212, 214, and / or 260 may identify whether the electronic device 101 is held based on information from the processor 120. At the same time, this is exemplary, and the communication processor 212, 214, and / or 260 may identify whether it is held based on an indicator associated with the intensity of the reflected wave, such as a voltage standing wave ratio (VSWR), without information from the application processor. For example, those skilled in the art will appreciate that whether it is a free space environment, whether an object is detected, and / or the type of the object may be identified based on VSWR, and the identification method is not limited.

[0086] Return to reference Figure 4a According to an embodiment, in operation 409, the electronic device 101 may control the RF circuit to provide a second RF signal corresponding to the first frequency band to a second antenna different from the first antenna among the multiple antennas based on the electronic device 101 being held. The second RF signal may mean an RF signal after the first RF signal in a time sequence, and the first RF signal and the second RF signal may be based on the first frequency band. Here, the control of the RF circuit may be, for example, a control corresponding to a transmission antenna jump or a control corresponding to a transmission antenna switch. As described above, for example, the second antenna may be an antenna corresponding to a closed state among the available antennas corresponding to the first frequency band. As described above, the electronic device 101 may change the transmission antenna from the first antenna corresponding to the open state to the antenna corresponding to the closed state based on the transmission antenna jump or the transmission antenna switch. Meanwhile, changing the transmission antenna from the first antenna to the second antenna based on the electronic device 101 being held is merely exemplary, and the change of the transmission antenna may also be performed without determining whether it is held. For example, the electronic device 101 may change the transmission antenna from the first antenna corresponding to the open state to the second antenna corresponding to the closed state based on the change of the folding state from the open state to the closed state. As described above, in the open state, the first antenna with relatively high performance can be used, and in the closed state, the second antenna with relatively high performance can be used as a transmission antenna. Hereinafter, a transmission antenna in a foldable electronic device is described.

[0087] Figure 4c is a view showing an antenna of an electronic device in an opened state according to an embodiment. Figure 4d is a view showing an antenna of an electronic device in a closed state according to an embodiment. Figure 4e 2 is a view illustrating human body contact in a closed state according to an embodiment.

[0088] refer to Figure 4c , antennas 451, 452, 453, 454, 455, 456 and 457 may be placed on the first housing 431 of the electronic device 101. Antennas 461, 462, 463, 464, 465, 466 and 467 may be placed on the second housing 432 of the electronic device 101. Here, antennas 451, 452, 453, 454, 455, 456 and 457 and / or antennas 461, 462, 463, 464, 465, 466 and 467 may be segmented antennas, but their types are not limited. The first housing 431 and the second housing 432 may be connected to a hinge structure 458. The hinge structure 458 may include, for example, a rotatable structure. Therefore, at least one housing may rotate around the hinge structure 458 as an axis, so that the electronic device 101 may be as Figure 4d Fold as shown. Figure 4d The folded state of the electronic device 101 can be referred to as a closed state.

[0089] Return to reference Figure 4c For example, the electronic device 101 may determine to send an RF signal of a first frequency band. The electronic device 101 may determine the antenna 455 corresponding to the first frequency band among the antennas as the transmission antenna. Antenna 455 may be, for example, a basic (or default) transmission antenna corresponding to the first frequency band. For example, when the folded state is an open state, antenna 455 may have better performance than other antennas in the first frequency band. Therefore, antenna 455 may be a basic transmission antenna. At the same time, it will be understood by those of ordinary skill in the art that even in the open state, the electronic device 101 may identify whether the antenna change condition is met, and may change the transmission antenna based on meeting the antenna change condition.

[0090] According to an embodiment, the folding state of the electronic device 101 may be changed from an open state to a closed state. Figure 4d, in the closed state, antennas 451, 452, and 453 placed on the upper side of the first housing 431 can be close to antennas 461, 462, and 463 placed on the upper side of the second housing 432. In the closed state, antennas 455, 456, and 457 arranged on the lower side of the first housing 431 can be close to antennas 465, 466, and 467 placed on the lower side of the second housing 432. The close arrangement of antennas may affect antenna performance. In particular, the distance between antennas 455 and 465 may be smaller than the distance between other antennas. Therefore, performance degradation may occur. Therefore, if the antenna 455 used in the open state is used continuously, the communication performance may deteriorate. Therefore, it may be desirable to change the transmission antenna. For example, the electronic device 101 can use an antenna corresponding to the closed state (e.g., 451 or 461) as a transmission antenna. In the closed state, the distance between antennas 451 and 461 may be greater than the distance between other antennas. Therefore, the antenna 451 having a relatively large distance between the antennas 451 and 461 can be determined as a transmission antenna, but this is exemplary, and the transmission antenna corresponding to the closed state is not limited. Since there is a possibility that the human body may contact the lower antennas 455, 456 and 457 by holding, the antenna 451 placed on the upper side can be determined as a transmission antenna, but it is not limited to this. For example, the distance between the antennas may be required to be equal to or greater than a predetermined distance (e.g., 0.4mm) to ensure good antenna performance. Therefore, any antenna that is a predetermined distance (e.g., 0.4mm) or greater from an adjacent antenna in a closed state can be used as a transmission antenna in a closed state, and the manner of setting and / or selecting a transmission antenna is not limited. For example, antenna 453 and antenna 451 can be used in MB / HB. Therefore, in a closed state, antenna 453 can be used as a transmission antenna corresponding to MB / HB. In an open state, antenna 451 can be used as a transmission antenna corresponding to MB / HB. Although not shown, the folded state of the electronic device 101 can be a semi-closed state. The semi-closed state may mean, for example, a state in which the angle between the first housing 431 and the second housing 432 has a specific value between the open state and the closed state, but is not limited thereto. In the semi-closed state, the electronic device 101 may determine the transmission antenna based on the distance between the antennas. For example, in the semi-closed state, the electronic device 101 may identify the transmission antenna corresponding to the corresponding angle. For example, a transmission antenna corresponding to the angle between the housings 431 and 432 may be placed, and the electronic device 101 may identify the transmission antenna corresponding to the specific angle. Alternatively, the electronic device 101 may also calculate the distance between the antennas at a specific angle in the semi-closed state, and determine the transmission antenna based on the calculation result. For example, the electronic device 101 may determine the antenna having the largest distance from the most adjacent antenna among the available antennas in a specific frequency band as the transmission antenna.Meanwhile, it will be understood by those of ordinary skill in the art that when the distance from the transmission antenna in use to the most adjacent antenna in the semi-closed state is a predetermined distance (eg, 0.4 mm) or more, the transmission antenna may be maintained.

[0091] At the same time, if Figure 4e As shown, a human body 459 (e.g., face) can be placed close to the antenna. For example, when the folded state of the electronic device 101 is a closed state, the user can place her body 459 close to the electronic device 101 to make a call. Figure 4a As shown, when the electronic device 101 is recognized to be held, the electronic device 101 can change the transmission antenna. For example, in the example, the electronic device 101 can change the transmission antenna based on the change from the folded state to the closed state and the recognition of holding. However, this is exemplary, and the electronic device 101 can also be configured to change the transmission antenna when the folded state is changed to the closed state without recognizing whether it is held. At the same time, as Figure 4d The folded electronic device shown makes the distance between antennas 451 and 461 greater than the distance between antennas 453 and 463 is merely exemplary. The electronic device 101 can also be implemented to be folded to have substantially the same distance between the antennas. It will be understood by those of ordinary skill in the art that even in this case, the electronic device 101 can change the transmission antenna based on the change of the folded state. For example, when the folded state is a closed state, the transmission antenna can be changed to an antenna with relatively good performance.

[0092] Figure 4f is a flowchart illustrating an operating method of an electronic device according to an embodiment.

[0093] Compared to the electronic device 101 Figure 4c and Figure 4d The directions shown in the drawings are opposite in the left / right direction, according to Figure 4f The electronic device 101 of the embodiment may be implemented to be folded in the up / down direction. The electronic device 101 may include a first housing 471 and a second housing 472. Antennas 481, 482, 483, 484, and 485 may be placed on the first housing 471. Antennas 491, 492, 493, and 494 may be placed on the second housing 472. The first housing 471 and the second housing 472 may be connected to a hinge structure 473. The hinge structure 473 may include a rotatable structure. Therefore, the housing may rotate around the hinge structure 473 as an axis. Therefore, as Figure 4f As shown, the first housing 471 and the second housing 472 may be rotated to face each other (eg, in an up / down direction).

[0094] According to an embodiment, when the folding state is an open state, the electronic device 101 may use, for example, an antenna 482 placed on the first housing 471 as a transmission antenna. According to an embodiment, when the folding state is a closed state, antennas 481 and 491 may be substantially in contact with each other, antennas 482 and 492 may be substantially in contact with each other, and antennas 483 and 493 may be substantially in contact with each other. For example, the distance between antennas 482 and 492 may be less than a predetermined distance (e.g., 0.4 mm), and the performance of antenna 482 may be reduced. At the same time, when the folding state is an open state, the distance between antennas 485 and 494 may be a predetermined distance (e.g., 0.4 mm). When the folding state is a closed state, antenna 485 may be used as a transmission antenna. For example, antennas 483 and 493 may be antennas configured for B41 band and / or N41 band, but are not limited thereto. As described above, the electronic device 101 may change the transmission antenna according to the change from the open state to the closed state. Alternatively, the electronic device 101 may change the transmission antenna based on the change to the closed state and the recognition of the grip. At the same time, if Figure 4f As shown, folding the electronic device so that the distance between antennas 485 and 494 is relatively large is only exemplary. The electronic device 101 can also be implemented to be folded to have substantially the same distance between the antennas. It will be understood by those skilled in the art that even in this case, the electronic device 101 can change the transmission antenna based on the change of the folding state. For example, when the folding state is a closed state, the transmission antenna can be changed to an antenna with relatively good performance.

[0095] Figure 5a is a flowchart illustrating an operating method of an electronic device according to an embodiment.

[0096] According to an embodiment, in operation 501, the electronic device 101 (eg, Figure 2a a first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2b The integrated communication processor 260 of the electronic device 101 can recognize that the folded state of the electronic device 101 is the open state. For example, the communication processor 212, 214 and / or 260 can receive information about the folded state of the electronic device 101 (e.g., information indicating the open state) from the application processor (e.g., processor 120), but this is exemplary, and the manner in which the communication processor 212, 214 and / or 260 recognizes the folded state is not limited. In another example, the communication processor 212, 214 and / or 260 can directly receive sensing data from the sensor. In operation 503, the electronic device 101 can control the RF circuit (e.g., Figure 3a The RF circuit 300 or Figure 3bThe RF circuit 310 of the electronic device 101 provides a first RF signal corresponding to the first frequency band to a first antenna among the multiple antennas. Here, the first antenna can be, for example, a transmission antenna corresponding to an open state, but is not limited thereto. In operation 505, the electronic device 101 can recognize that the folded state of the electronic device 101 changes from an open state to a closed state. The electronic device 101 can recognize that the folded state of the electronic device 101 is a closed state. For example, the communication processor 212, 214 and / or 260 can receive information about the folded state of the electronic device 101 (e.g., information indicating a closed state) from an application processor (e.g., processor 120), but this is exemplary, and the manner in which the communication processor 212, 214 and / or 260 recognizes the folded state is not limited.

[0097] According to an embodiment, in operation 507, the electronic device 101 may identify whether the electronic device 101 is held by a user. In operation 509, the electronic device 101 may control the RF circuit to provide a second RF signal corresponding to the first frequency band to a second antenna different from the first antenna among multiple antennas based on the electronic device 101 being identified as being held ("Yes" in 507). For example, operation 509 may be a forced transmission antenna change. The second antenna may be, for example, a transmission antenna corresponding to a closed state, but is not limited thereto. When it is identified that the electronic device 101 is held, the electronic device 101 may perform a transmission antenna change (e.g., transmission antenna hopping or transmission antenna switching) without determining whether the measured parameters meet the antenna change condition, and this may be referred to as a forced antenna change. Based on being identified as other ("No" in 507), the electronic device 101 may identify in operation 511 whether the measured parameters meet the antenna change condition. For example, operation 511 may be a transmission antenna change algorithm on state. When the measured parameter satisfies the antenna change condition ("Yes" in 511), in operation 509, the electronic device 101 may control the RF circuit to provide a second RF signal corresponding to the first frequency band to a second antenna different from the first antenna among the multiple antennas. If the measured parameter does not satisfy the antenna change condition ("No" in 511), the electronic device 101 may maintain the transmission antenna. When identified in other ways, it may be determined whether to change the transmission antenna based on whether the measured parameter satisfies the antenna change condition, and this may be referred to as a transmission antenna change algorithm on state. Meanwhile, the state of maintaining the transmission antenna regardless of the measured parameter may be referred to as a transmission antenna change algorithm off state.

[0098] Figure 5b is a flowchart illustrating an operating method of an electronic device according to an embodiment of the present invention.

[0099] According to an embodiment, in operation 521, the electronic device 101 (eg, Figure 2aa first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2b The integrated communication processor 260 of the electronic device 101 may recognize that the folded state of the electronic device 101 is the opened state. In operation 523, the electronic device 101 may control the RF circuit (eg, Figure 3a The RF circuit 300 or Figure 3b The RF circuit 310 of the electronic device 101 provides a first RF signal corresponding to the first frequency band to a first antenna among the multiple antennas. Here, the first antenna can be, for example, a transmission antenna corresponding to the open state, but is not limited thereto. In operation 525, the electronic device 101 can recognize that the folded state of the electronic device 101 changes from the open state to the closed state. The electronic device 101 can recognize that the folded state of the electronic device 101 is a closed state. For example, the communication processor 212, 214 and / or 260 can receive information about the folded state of the electronic device 101 (e.g., information indicating a closed state) from the application processor (e.g., the processor 120), but this is exemplary, and the manner in which the communication processor 212, 214 and / or 260 recognizes the folded state is not limited.

[0100] According to an embodiment, in operation 527, the electronic device 101 may identify whether the electronic device 101 is held by a user. In operation 529, the electronic device 101 may control the RF circuit to provide a second RF signal corresponding to the first frequency band to a second antenna different from the first antenna among the multiple antennas based on the electronic device 101 being identified as being held ("Yes" in 527). Based on being identified as not being held ("No" in 527), the electronic device 101 may hold the antenna in operation 531. For example, operation 531 may be a transmission antenna change algorithm off state. Although in Figure 5a In the method, whether to change the transmission antenna is determined according to whether the parameters measured when the device is not held meet the antenna change condition, but in Figure 5b It is possible to hold the antenna when not being held regardless of the parameter being measured.

[0101] Figure 6 is a flowchart illustrating an operating method of an electronic device according to an embodiment.

[0102] According to an embodiment, in operation 601, the electronic device 101 (eg, Figure 2a a first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2b The integrated communication processor 260 of the embodiment can control the RF circuit (e.g., Figure 3a The RF circuit 300 or Figure 3bThe RF circuit 310) provides a first RF signal corresponding to the first frequency band to a first antenna among the multiple antennas. Here, the first antenna can be, for example, a transmission antenna corresponding to an open state, but is not limited thereto. In operation 603, the electronic device 101 can identify whether the folded state of the electronic device 101 is a closed state. When it is identified that the folded state is a closed state ("yes" in 603), the electronic device 101 can determine whether to change the antenna in operation 605 based on whether the measured parameters meet the antenna change conditions. For example, operation 605 can be the state where the transmission antenna change algorithm is turned on. Figure 6 In an embodiment of the present invention, when the measured parameter (e.g., the reception strength of each antenna, but not limited thereto) satisfies the antenna change condition, the electronic device 101 may perform the antenna change instead of performing the antenna change immediately when the folded state of the electronic device 101 is identified as a closed state. When the measured parameter (e.g., the reception strength of each antenna, but not limited thereto) does not satisfy the antenna change condition although the folded state is a closed state, the electronic device 101 may maintain the antenna. When it is identified that the folded state is not a closed state ("No" in 603), the electronic device 101 may maintain the antenna in operation 607. At the same time, according to an embodiment, when the folded state is identified as a closed state and the holding of the electronic device 101 is identified, the electronic device 101 may be configured to determine whether to change the antenna in operation 605 based on whether the measured parameter satisfies the antenna change condition. For example, operation 607 may be a transmission antenna change algorithm off state.

[0103] Figure 7a is a flowchart illustrating an operating method of an electronic device according to an embodiment. Figure 7b describe Figure 7a Embodiment of the invention. Figure 7b is a view showing the arrangement of an antenna and a camera according to an embodiment.

[0104] refer to Figure 7a According to an embodiment, in operation 701, the electronic device 101 (eg, Figure 2a a first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2b The integrated communication processor 260 of the embodiment can control the RF circuit (e.g., Figure 3a The RF circuit 300 or Figure 3b The RF circuit 310 of the camera 310 provides a first RF signal corresponding to a first frequency band to a first antenna among the plurality of antennas. In operation 701, the first antenna may be, for example, a transmission antenna configured to correspond to the first frequency band when the camera is turned off. For example, referring to Figure 7b, the first camera 723 and the second camera 721 may be placed on the PCB 722 of the electronic device 101. For example, the second camera 721 may be a front camera, and the first camera 723 may be a rear camera, but is not limited thereto. The electronic device 101 may include a first antenna 713, a second antenna 711, and a third antenna 712. For example, the first antenna 713 may be a basic (or default) transmission antenna corresponding to a first frequency band, for example. Therefore, when the first camera 723 is turned off, the electronic device 101 may control the RF circuit to provide an RF signal of the first frequency band to the first antenna 713.

[0105] Return to reference Figure 7a According to an embodiment, in operation 703, the electronic device 101 may identify whether the camera is turned on. When the camera is turned on ("Yes" in 703), in operation 705, the electronic device 101 may control the RF circuit to provide a second RF signal corresponding to the first frequency band to a second antenna different from the first antenna among the multiple antennas. When the camera is not turned on ("No" in 703), the electronic device 101 may keep the antenna turned on in operation 707. For example, referring to Figure 7b , the electronic device 101 may control the RF circuit to provide the second RF signal to the second antenna 711 which is different from the first antenna 713. Figure 7b , the distance between the first antenna 713 and the first camera 723 may be relatively small. Since the RF signal is provided from the first antenna 713, the electromagnetic waves generated from the first antenna 713 may affect the first camera 723. If the use of the first antenna 713 is maintained while the first camera 723 is turned on, the quality of the image obtained by the first camera 723 may deteriorate. In order to maintain the image quality, the transmission power of the RF signal should be reduced (for example, by 7dB), but this may deteriorate the communication quality. Therefore, in a state where the first camera 723 is turned on, the electronic device 101 may change the transmission antenna from the first antenna 713 as the basic transmission antenna to the second antenna 711. The electronic device 101 may control the RF circuit so that the second RF signal of the first frequency band is provided to the second antenna 711. Since the distance between the second antenna 711 and the first camera 723 is relatively large, the electromagnetic waves generated from the second antenna 711 may have a relatively small effect on the first camera 723. Therefore, the electronic device 101 may not reduce or may reduce the transmission power of the RF signal provided to the second antenna 711 to a relatively small extent, thereby preventing (or reducing) deterioration in communication quality and / or deterioration in quality of the image obtained by the first camera 723.

[0106] According to another embodiment, the electronic device 101 may change the transmission antenna from the first antenna 713 to the third antenna 712 based on the opening of the first camera 723. At the same time, the second camera 721 may be turned on while performing communication based on the third antenna 712. The distance between the third antenna 712 and the second camera 721 may be relatively small, and the electromagnetic waves generated from the third antenna 712 may affect the second camera 721. The electronic device 101 may change the transmission antenna based on the opening of the second camera 721. For example, when the first camera 723 is turned off and the second camera 721 is turned on, the electronic device 101 may change the transmission antenna to the first antenna 713 as the basic transmission antenna. For example, when both cameras 721 and 723 are turned on, the electronic device 101 may determine that the second antenna 711 having the least influence (or having the largest spacing) on ​​both cameras 721 and 723 is the transmission antenna.

[0107] Figure 7c is a flowchart illustrating an operating method of an electronic device according to an embodiment.

[0108] According to an embodiment, in operation 731, the electronic device 101 (eg, Figure 2a a first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2b The integrated communication processor 260 of the embodiment can control the RF circuit (e.g., Figure 3a The RF circuit 300 or Figure 3b The RF circuit 310 of the electronic device 101 provides a first RF signal corresponding to the first frequency band to a first antenna among the multiple antennas. In operation 731, the first antenna may be, for example, a transmission antenna configured corresponding to the first frequency band when the camera is turned off. In operation 733, the electronic device 101 may identify whether the camera is turned on. When the camera is not turned on ("No" in 733), the electronic device 101 may maintain the antenna in operation 739. When the camera is turned on ("Yes" in 733), the electronic device 101 may identify in operation 735 whether the MTPL of the second RF signal exceeds a threshold. When the MTPL exceeds the threshold ("Yes" in 735), in operation 737, the electronic device 101 may control the RF circuit to provide a second RF signal corresponding to the first frequency band to a second antenna among the multiple antennas that is different from the first antenna. When the MTPL is the threshold or less ("No" in 735), the electronic device 101 may maintain the antenna in operation 739. For example, due to Figure 7bThe distance between the first antenna 713 and the first camera 723 is relatively small, so the electromagnetic waves generated from the first antenna 713 may affect the first camera 723. At the same time, when the transmission power of the RF signal applied to the first antenna 713 is relatively small, the influence of the electromagnetic waves generated from the first antenna 713 on the first camera 723 can also be reduced. Therefore, when electromagnetic waves with relatively small amplitudes are generated, it may be preferable to keep using the basic transmission antenna rather than performing antenna changes. Therefore, as Figure 7c As shown, the electronic device 101 can be configured to perform a transmission antenna change when the MTPL exceeds a threshold, and to maintain the transmission antenna when the MTPL is a threshold or less. The threshold value (e.g., 16dBm) can be determined as a value at which the camera can measure an image of relatively good quality, but is not limited to this. For example, when 5G SA is used, a 3dB transmission power attenuation relative to the average transmission power can be performed, and when EN-DC is used, a 10dB transmission power attenuation relative to the average transmission power can be performed. Therefore, a context in which the MTPL is a threshold (e.g., 16dBm) or less can occur, and in this case, the transmission antenna can be maintained.

[0109] Figure 7d is a flowchart illustrating an operating method of an electronic device according to an embodiment.

[0110] According to an embodiment, in operation 741, the electronic device 101 (eg, Figure 2a a first communication processor 212, Figure 2a The second communication processor 214 and / or Figure 2b The integrated communication processor 260 of the embodiment can control the RF circuit (e.g., Figure 3a The RF circuit 300 or Figure 3b The RF circuit 310 of the electronic device 101 provides a first RF signal corresponding to the first frequency band to a first antenna among multiple antennas. In operation 741, the first antenna may be, for example, a transmission antenna configured corresponding to the first frequency band when the camera is turned off. In operation 743, the electronic device 101 may identify whether the camera is turned on. When the camera is not turned on ("No" in 743), the electronic device 101 may maintain the antenna in operation 749. When the camera is turned on ("Yes" in 743), the electronic device 101 may identify whether the transmission power of the second RF signal exceeds a threshold in operation 745. When the transmission power exceeds the threshold ("Yes" in 745), in operation 747, the electronic device 101 may control the RF circuit to provide a second RF signal corresponding to the first frequency band to a second antenna among the multiple antennas that is different from the first antenna. When the transmission power is the threshold or less ("No" in 745), the electronic device 101 may maintain the antenna in operation 749. As combined Figure 7cAs described, when generating electromagnetic waves with relatively small amplitudes, it may be preferable to maintain the use of the basic transmission antenna rather than perform an antenna change. Figure 7d As shown, the electronic device 101 can be configured to perform a transmission antenna change when the transmission power exceeds a threshold, and maintain the transmission antenna when the transmission power is a threshold or less. The threshold can be determined as a value at which the camera can measure a relatively good quality image, but is not limited thereto.

[0111] Figure 8 is a flowchart illustrating an operating method of an electronic device according to an embodiment.

[0112] According to an embodiment, in operation 801, the electronic device 101 (eg, the communication processor 212, 214, and / or 260) may control the RF circuit (eg, Figure 3a The RF circuit 300 or Figure 3b RF circuit 310 of the embodiment of the present invention provides a first RF signal corresponding to the first frequency band to a first antenna among multiple antennas. In operation 803, the electronic device 101 may identify one of the sub-frequencies in the frequency band. In operation 805, the electronic device 101 may identify whether the measured parameter satisfies the antenna change condition corresponding to the identified sub-frequency. At the same time, the electronic device 101 may be configured to identify the antenna change condition corresponding to the identified sub-frequency, but is not limited thereto. For example, the antenna change condition may be set to be different for each sub-frequency. For example, a high threshold and / or a low threshold may be set to be different for each sub-frequency. For example, the imbalance between antennas (e.g., PPx antennas and DRx antennas) may be set to be different for each sub-frequency. For example, Table 1 is an example of a threshold (e.g., a high threshold) for each sub-frequency in the N78 frequency band.

[0113] [Table 1]

[0114]

[0115] As described above, when the sum of the received strength difference (RSRP diff current) and MTPL diff at the current time is a high threshold or greater, the electronic device 101 can perform a transmission antenna change. Here, the high threshold can be set to be different for each of the low band (3750MHz), the middle band (3840MHz) and the high band (3903MHz) of the N78 band. The electronic device 101 can identify whether the antenna change condition set for each sub-band is met in the N78 band. When the antenna change condition is met ("yes" in 805), in operation 807, the electronic device 101 can control the RF circuit to provide the second RF signal corresponding to the first band to the second antenna different from the first antenna in the multiple antennas. When the antenna change condition is not met ("no" in 805), the electronic device 101 can keep the antenna in operation 809. For example, it is assumed that the electronic device 101 uses the middle band in the N78 band. The sum of the received strength difference (RSRP diff current) and MTPLdiff measured by the electronic device 101 may be greater than or equal to threshold 1, but may be less than threshold 2. Although the antenna change condition corresponding to the low frequency band is satisfied, the antenna change condition corresponding to the mid frequency band is not satisfied, so that the electronic device 101 can maintain the transmission antenna. For example, Table 2 is an example of a threshold value (e.g., a high threshold value) for each sub-frequency in the N78 frequency band.

[0116] [Table 2]

[0117]

[0118] Different thresholds are set for the three sub-frequencies of the N78 band in Table 1, and different thresholds can be set for the five sub-frequencies of the N78 band in Table 2, but the number of divisions is not limited. Since the N78 band is relatively wide, the sub-thresholds as in Table 2 can be set. As described above, since the RSRP diff of the RSRP with poor performance at a specific sub-frequency is relatively large, the transmission antenna may not be changed, or the situation where the transmission antenna change is not performed despite the need at a specific sub-frequency can be prevented and / or reduced. For example, when the total radiated power (TRP) deteriorates, it may mean that the Rx performance in the TDD band also deteriorates. Therefore, in the case where a specific antenna is used for the N78 band, when the RSRP is PRx-91dBm and Drx-90dBm, RSRP Diff may be increased to PRx-93.4dBm, DRx-90dBm even in the context of the same electric field. If the high threshold is 5dB and the imbalance is set to 1dB with reference to 3750MHz, RSRP Diff+MTPL Diff is 6dB as a result. Therefore, the transmission antenna change can be performed to 5dB (which is the high threshold) or more. If the imbalance is 1dB, PRx becomes -91dBm when the DRx electric field is -90dBm, and if the PRx electric field deteriorates by 5dB when the MTPL is the same, the transmission antenna change can be performed. However, in the case where the imbalance is also set to 1dB for 3930MHz, when the DRx electric field is -90dBm, PRx is -93.4dBm, so that even when the PRx electric field deteriorates by only 2.6dB, the transmission antenna change can be performed. As described above, in order to prevent and / or reduce the transmission antenna change performed according to the relatively small degradation level of 2.6dB, the high threshold and / or imbalance can be set to be different for 3930Mhz. For example, in the case where the imbalance is set to 3.4 dB, the transmission antenna change may not be performed until it deteriorates to 6 dB. Meanwhile, if the imbalance is set to 3.4 dB for the entire N78 band, the transmission antenna change may be performed only when it degrades to 7.4 dB at 3750 MHz. Therefore, even in one frequency band, the threshold and / or imbalance of the antenna change condition may be set to be different for each sub-frequency. According to an embodiment, the electronic device 101 may include at least one communication processor ( Figure 2a 212 or 214 or Figure 2b 260), connected to at least one communication processor ( Figure 2a 212 or 214 or Figure 2b 260)RF circuit ( Figure 3a 300 or Figure 3b 310), and connected to the RF circuit ( Figure 3a 300 or Figure 3b The plurality of antennas (310) Figure 3a 305 and 315 or Figure 3b 325 and 327). At least one communication processor ( Figure 2a 212 or 214 or Figure 2b 260) may be configured to control the RF circuit ( Figure 3a 300 or Figure 3b 310) provides a first RF signal corresponding to a first frequency band to a plurality of antennas ( Figure 3a 305 and 315 or Figure 3b At least one communication processor ( Figure 2a 212 or 214 or Figure 2b 260) may be configured to: based on identifying that the folded state of the electronic device 101 is the closed state, identify whether the electronic device 101 is held. At least one communication processor ( Figure 2a 212 or 214 or Figure 2b 260) may be configured to control the RF circuit ( Figure 3a 300 or Figure 3b 310) provides a second RF signal corresponding to the first frequency band to a plurality of antennas ( Figure 3a 305 and 315 or Figure 3b A second antenna different from the first antenna in 325 and 327).
