Description

Technical Field

[0001] Embodiments of this disclosure relate to an electronic device and a method for using the electronic device to change the path of a transmitting antenna. Background Technology

[0002] To meet the ever-growing demand for wireless data services since the commercialization of 4G communication systems, efforts are underway to develop 5G communication systems. To achieve high data transmission rates and provide faster data transfer speeds, 5G communication systems are also being considered for implementation not only in the high-frequency bands used in 3G and LTE communication systems, but also in ultra-high frequency bands.

[0003] Schemes for implementing 5G communication systems can include standalone (SA) and non-standalone (NSA) schemes. Specifically, an NSA scheme can be a scheme that uses both LTE and New Radio (NR) communication. In an NSA scheme, the electronic device can verify whether the received signal quality associated with at least two antennas performing LTE communication and at least two antennas performing NR communication meet reference values, and change the antenna used for transmitting data to an antenna that meets the reference values.

[0004] The above information may be provided as relevant technology to aid in understanding the purposes of this disclosure. There is no claim or determination as to whether any of the foregoing content applies to prior art relating to this disclosure. Summary of the Invention

[0005] Technical issues Electronic device 101 is designed to overcome the limitation that antenna switching is difficult to perform when the maximum average power value (i.e., the average power limit) is below a specified level due to the reduction in the relative difference of the reference signal received power (RSRP) values ​​on each antenna path. The maximum average power value can refer to the maximum power value that satisfies the specific absorption rate (SAR) on the antenna among the average power values ​​over a certain period of time.

[0006] The electronic device may include a first antenna, a second antenna disposed at a location different from where the first antenna is disposed, and a processor. The processor may select an antenna for outputting a signal from the first antenna and the second antenna based on the amplitude of the maximum average power of the signal output via the first antenna satisfying the time-averaged specific absorptivity (SAR) configured in the electronic device, and a maximum transmit power limit of the signal output by at least one of the first antenna and the second antenna configured via a cellular network. Alternatively, the processor may select an antenna for outputting a signal from the first antenna and the second antenna based on the difference between the amplitude of the maximum average power of the signal output via the first antenna satisfying the SAR configured in the electronic device and the amplitude of the maximum average power of the signal output via the second antenna satisfying the SAR configured in the electronic device.

[0007] A method for operating an electronic device may include the following operations: selecting an antenna for outputting a signal from a first antenna and a second antenna based on the amplitude of the maximum power of a signal output via a first antenna satisfying a specific absorptivity (SAR) configured in the electronic device and the maximum transmit power level of a signal output via at least one of a first antenna and a second antenna configured via a cellular network; and selecting the antenna for outputting a signal from the first antenna and the second antenna based on the difference between the amplitude of the maximum power of the signal output via the first antenna satisfying a specific absorptivity (SAR) configured in the electronic device and the amplitude of the maximum power of the signal output via the second antenna satisfying a specific absorptivity (SAR) configured in the electronic device.

[0008] The electronic devices described in this document can prevent backoff operations that may occur when SAR margin is reduced to minimize call drops and silences. Attached Figure Description

[0052] The third RFIC 226 can convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter referred to as a 5G Above6 RF signal) in the 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second network 294 (e.g., a 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and preprocessed via the third RFFE 236. The third RFIC 226 can convert the preprocessed 5G Above6 RF signal back into a baseband signal, allowing the preprocessed 5G Above6 RF signal to 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.

[0053] According to an embodiment, electronic device 101 may include a fourth RFIC 228, 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 intermediate frequency band (e.g., about 9 GHz to about 11 GHz) RF signal (hereinafter referred to as an IF signal), 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. Upon reception, the 5G Above6 RF signal may be received from a second network 294 (e.g., a 5G network) via 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 back into a baseband signal, such that the IF signal can be processed by the second communication processor 214.

[0054] According to an embodiment, the first RFIC 222 and the second RFIC 224 can be implemented as at least a portion of a single chip or a single package. According to an embodiment, the first RFFE 232 and the second RFFE 234 can be implemented as at least a portion of a single chip or a single package. According to an embodiment, at least one antenna module in the first antenna module 242 or the second antenna module 244 can be omitted or coupled to another antenna module to process RF signals in multiple corresponding frequency bands.

[0055] According to an embodiment, the third RFIC 226 and the antenna 248 can be disposed on the same substrate to form a third antenna module 246. For example, the wireless communication module 192 or the processor 120 can be disposed on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 can be disposed on a portion of a second substrate (e.g., a sub-PCB) separate from the first substrate (e.g., the lower surface), and the antenna 248 can be disposed on another portion of the substrate (e.g., the upper surface), thereby forming the third antenna module 246. By disposing the third RFIC 226 and the antenna 248 on the same substrate, the length of the transmission line between the third RFIC 226 and the antenna 248 can be reduced. This can reduce signal loss (e.g., attenuation) in the high-frequency band (approximately 6 GHz to 60 GHz) used in 5G network communication, for example, due to the transmission line. Therefore, the electronic device 101 can improve the quality or speed of communication with the second network 294 (e.g., a 5G network).

[0056] According to an embodiment, antenna 248 may be configured as an antenna array including a plurality of antenna elements that can be used for beamforming. In this case, third RFIC 226 may include, for example, a plurality of phase shifters 238 corresponding to the plurality of antenna elements as part of third RFFE 236. During transmission, each of the plurality of phase shifters 238 may shift the phase of a 5G Above6 RF signal to be transmitted via the corresponding antenna element to an external location (e.g., a base station of a 5G network) of electronic device 101. During reception, each of the plurality of phase shifters 238 may shift the phase of a 5G Above6 RF signal received from the external location via the corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between electronic device 101 and the external location.

[0057] The second network 294 (e.g., a 5G network) can operate independently of the first network 292 (e.g., a legacy network) (e.g., standalone mode (SA)) or when connected to the first network 292 (e.g., a legacy network) (e.g., non-standalone mode (NSA)). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or a next-generation RAN (NGRAN)) and may not include a core network (e.g., a next-generation core (NGC)). In this case, the electronic device 101 can access the access network of the 5G network and then access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., an evolved cascade 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) can be stored in memory 130 and accessed by other components (e.g., processor 120, the first communication processor 212, or the second communication processor 214).

[0058] Figure 3 The network environment of an electronic device 101 that transmits data using multiple communication schemes according to an embodiment of the present disclosure is shown.

[0059] Reference Figure 3 Electronic device 101 can transmit data via multiple networks using multiple transmission paths. Electronic device 101 includes a switch 310 and can transmit data using multiple transmission paths or using a single transmission path.

[0060] Electronic device 101 can use first antenna 320 (e.g., Figure 2 The second antenna module 244 or the third antenna module 246) transmits data using the first communication scheme, and uses the second antenna 325 (e.g., Figure 2 The first antenna module 242 transmits data using a second communication scheme. For example, when the first communication scheme is 5G communication, the electronic device 101 can use the first antenna 320 (330) to connect to the gNB 340. When the second communication scheme is LTE communication, the electronic device 101 can use the second antenna 325 (335) to connect to the eNB 345. Both the gNB 340 and the eNB 345 can connect to a core network 350.

[0061] Figure 4 This is a cross-sectional view of an electronic device according to an embodiment.

[0062] According to an embodiment, electronic devices (e.g., Figure 2The electronic device 200 may include a wireless communication circuit 410, a Wi-Fi communication circuit 450, and multiple antennas 411, 412, 413, 414, 420, 430, 433, 441, 442, 444, 451, and 452. The electronic device 200 may include a system unit 460 and an upper portion 470.

[0063] According to an embodiment, the wireless communication circuit 410 can be electrically connected to the second antenna 420 and the third antenna 430. The wireless communication circuit 410 can be electrically connected via a first switch 401 to the first-1 antenna 411, the first-2 antenna 412, the first-3 antenna 413, and the first-4 antenna 414. The wireless communication circuit 410 can be electrically connected via a second switch 402 to the fourth-1 antenna 441, the fourth-2 antenna 442, the fourth-3 antenna 433, and the fourth-4 antenna 444.

[0064] According to an embodiment, the Wi-Fi communication circuit 450 can be electrically connected to Wi-Fi#1 451 and Wi-Fi#2 452.

[0065] Electronic device 200 may include a structure that determines the antenna resonant frequency and bandwidth by means of the length of a metal frame. Figure 2 The electronic device 101 can be used by setting components (e.g., transceivers, LPAMIDs, FEMs, duplexers, and filters) on a PCB board. The electronic device 101 can use a duplexer to electrically transmit a band-specific signal generated by the transceiver to a specific antenna.

[0066] Furthermore, the electronic device 200 can use a metal frame as an antenna. When the distance between the human body and the electronic device 200 decreases, the resonant performance of the antenna implemented corresponding to the target frequency can decrease. The resonant frequency of the antenna can change when the human body approaches. In a structure using a metal frame as an antenna, there may be no device between the antenna of the electronic device 200 and the human body. The human body can directly contact the antenna on the electronic device 200. The energy radiated from the antenna of the electronic device 200 can be absorbed by the human body. In the case of direct contact between the antenna and the human body, the electronic device 200 can reduce the energy radiated from the antenna to meet usage standards (e.g., SAR radio standards, electromagnetic wave absorptivity, power density standards, etc.). These standards limit electromagnetic waves to certain levels due to the potential negative impact of electromagnetic waves on the human body. When the energy radiated from the antenna decreases, the data transmission performance of the antenna may deteriorate.

[0067] According to embodiments, electronic device 200 can solve the problems of covering various frequency bands with a limited number of antennas, the difficulty in meeting SAR requirements due to direct contact between the antenna and the human body, and the degradation of data transmission performance while reducing the antenna's transmission power to meet SAR requirements. The operation of electronic device 200 in this document is described based on SAR, but the same functionality can also be applied to power density (PD). Additionally, electronic device 200 can adjust the maximum power value so that the average power over a certain time period meets the specific absorption rate (SAR) requirement on the antenna. Electronic device 200 can use a first switch 401 and a second switch 402 to connect multiple antennas to a single port. According to embodiments, electronic device 200 can use the first switch 401 and the second switch 402 to separate antennas for each frequency band. For example, when a human body approaches a specific antenna, electronic device 200 can use the first switch 401 and the second switch 402 to use another antenna located away from the human body.

[0068] Figure 5 The location of the antenna on the electronic device according to an embodiment is shown.

[0069] according to Figure 5 Electronic devices (e.g.) Figure 1 The electronic device 101 may include a first antenna 501 supporting a first communication and a second antenna 503 supporting a second communication. Figure 5 The number of antennas shown is merely an example, and the electronic device 101 may include, but is not limited to, the number of antennas. Furthermore, Figure 5 The antenna positions shown are merely examples, and the antenna positions are not limited to these. Figure 5 The location shown.

[0070] Reference Figure 5 The electronic device 101 may include a first antenna 501 and a second antenna 503 physically disposed at separate locations.

[0071] For example, when electronic device 101 uses first antenna 501 to perform communication, the processor (e.g., Figure 1 The processor 120 can determine whether to switch to the second antenna 503 based on specific conditions. According to an embodiment, the specific conditions for determining whether to switch antennas may include satisfying the maximum average power value of the specific absorption rate (SAR) on the first antenna 501 (i.e., the average power limit) and the maximum power value of the first antenna 501 (i.e., Pmax: the maximum antenna power).

[0072] According to an embodiment, the processor 120 can determine that the antenna for transmitting wireless signals is the second antenna 503 based on the difference between the maximum power value that the electronic device 101 can have on the first antenna 501 and the average maximum power value that satisfies the time-averaged specific absorptivity (SAR) on the first antenna 501 exceeding a specified level. According to an embodiment, the difference between the maximum power value that the electronic device 101 can have on the first antenna 501 and the average maximum power value that satisfies the time-averaged specific absorptivity (SAR) on the first antenna 501 can refer to a value obtained by subtracting an average power limit from the Pmax (i.e., the maximum antenna power) of the first antenna 501. Pmax can include the maximum power value that the electronic device 101 can have on the first antenna 501. The average power limit can include the maximum power value that satisfies the specific absorptivity (SAR) of the power value averaged on the first antenna 501 over a specific time period.

[0073] Processor 120 may determine that the antenna used to transmit wireless signals is the second antenna 503 based on the value obtained by subtracting the average power limit from Pmax exceeding a specified value (e.g., 10 dB). Conversely, in the case of transmitting signals via the second antenna 503, processor 120 may determine that the antenna used to transmit wireless signals is the first antenna 501 based on the value obtained by subtracting the average power limit from Pmax of the second antenna exceeding a specified value (e.g., 10 dB).

[0074] According to an embodiment, when the power value used to satisfy SAR is relatively low compared to the maximum power on the path of the signal transmitted via the first antenna 501, the value obtained by subtracting Plimit from Pmax of the Pmax antenna can exceed a specified value (e.g., 10 dB). For example, when the power value used to satisfy SAR decreases, the electronic device 101 may experience a margin deficiency phenomenon due to a backoff caused by insufficient margin in satisfying SAR. According to an embodiment, a method for adjusting the antenna output to satisfy SAR includes a method for setting a fixed value standard (e.g., a power limit) and confirming whether the corresponding standard is exceeded, and a time-averaged SAR (TAS) control scheme for confirming that the average power does not exceed the SAR standard based on an average value standard (e.g., an average power limit). For example, a time-averaged SAR scheme is a scheme that continuously confirms the transmitted power (TX power) at a specific time interval. The TAS scheme can control the power so that the average value does not exceed the power limit (Plimit) by ensuring that the Plimit value is not exceeded on average.

[0075] A fallback operation can refer to the operation of electronic device 101 without using maximum power for stable operation, but limiting the power to only a point below a certain level (e.g., -3 dB). Due to the fallback operation, the transmit power may be insufficient, and therefore communication may not be smooth. Processor 120 can replace the antenna used for transmission to maintain smooth communication. According to an embodiment, the fallback operation may include the operation of reducing the transmit power of the antenna of electronic device 101 to a specific level. When a user makes a call in electronic device 101, the user's head may be close to electronic device 101, so the power can be reduced to reduce the amount of electromagnetic waves transmitted to meet SAR standards. When electronic device 101 reduces power, communication performance may degrade. According to an embodiment, electronic device 101 can be replaced with another antenna so that communication performance does not degrade.

[0076] However, when Plimit is less than a specified level (e.g., 13 dB), the electronic device according to the comparative embodiment may experience a decrease in the reference signal received power (RSRP) value on each antenna path, thus failing to meet the antenna switching conditions, which may make it difficult to replace the antenna used for transmission. Plimit may refer to the magnitude of the maximum power of the signal output via the first antenna that satisfies the specific absorption rate (SAR) configured in the electronic device. Alternatively, Plimit may refer to the magnitude of the maximum power of the signal output via the second antenna that satisfies the specific absorption rate (SAR) configured in the electronic device. The second antenna may be located at a different position on the electronic device than the first antenna. When Plimit is less than the specified level, the maximum power value satisfying the specific absorption rate (SAR) can itself decrease, and therefore, the difference between the RSRP values ​​on each antenna path can also decrease. Since the electronic device according to the comparative embodiment performs antenna switching based on the relative difference between the RSRP values ​​on each antenna path, when Plimit is less than the specified level, antenna switching may be difficult to perform because the relative difference between the RSRP values ​​on each antenna path can decrease.

[0077] According to the document, when Plimit is less than a specified level, in order to overcome the difficulty of performing antenna switching due to the decrease in the relative difference of RSRP values ​​on each antenna path, the electronic device 101 can determine different conditions for performing antenna switching.

[0078] According to an embodiment, processor 120 can confirm RSRP at a specific period (e.g., 640 ms). Processor 120 can determine the difference between the RSRP values ​​at the beginning and end of a period. Processor 120 can determine whether to perform antenna switching based on the difference in RSRP during a period and the difference in the maximum transmit power limit (MTPL) during a period. The specific period can vary depending on the configuration.

[0079] According to an embodiment, processor 120 can calculate the average of the RSRP difference determined in a first cycle and the RSRP difference determined in a second cycle. Processor 120 can determine whether to switch antennas based on the difference between the average RSRP difference over a cycle and the maximum transmit power limit (MTPL). For example, electronic device 101 can switch antennas when the sum of the RSRP gain and the TX power gain of the antenna to be moved is greater than a specific threshold. Electronic device 101 can determine whether the sum of the difference between RSRP1 and RSRP0 (RSRP1-RSRP0) and the TX power gain at a specific time point (TX1 MTPL-TX0 MTPL) is greater than a threshold. Electronic device 101 can determine to switch antennas based on the sum of the difference between RSRP1 and RSRP0 (RSRP1-RSRP0) and the TX power gain (TX1 MTPL-TX0 MTPL) being greater than a threshold.

[0080] According to an embodiment, the processor 120 can determine which antenna, the first antenna 501 or the second antenna 503, to use to transmit a signal based on the maximum power value of the specific absorption rate (SAR) on the first antenna 501 and the maximum power value of the electronic device on the first antenna 501.

[0081] According to an embodiment, the processor 120 can determine which antenna, the first antenna 501 or the second antenna 503, to use based on the difference between the maximum power value satisfying the specific absorptivity (SAR) on the first antenna 501 and the maximum power value satisfying the specific absorptivity (SAR) on the second antenna 503.

[0082] According to an embodiment, the processor 120 can determine which antenna, the first antenna 501 or the second antenna 503, to use based on the difference between the maximum power value of the second antenna that satisfies the TAS and the maximum power value that satisfies the TAS, using a time-averaged SAR (TAS) control scheme. The time-averaged SAR (TAS) control scheme confirms that the average power does not exceed the SAR standard based on an average value standard (e.g., an average power limit) on the first antenna 501.

[0083] According to an embodiment, the processor 120 can determine that the second antenna 503 is an antenna for transmitting wireless signals based on the fact that the amplitude of the transmission power via the first antenna 501 is equal to the amplitude of the maximum power of the electronic device.

[0084] According to an embodiment, the processor 120 can determine that the second antenna is an antenna for transmitting wireless signals based on the difference between the maximum power value that the electronic device can have on the first antenna 501 and the average maximum power value that satisfies the specific absorption rate (SAR) on the first antenna 501 exceeding a specified level.

[0085] According to an embodiment, when transmitting power via the first antenna 501, the processor 120 may change the antenna used to transmit wireless signals to the second antenna 503 based on the fact that the maximum power value of the specific absorption rate (SAR) of the first antenna 501 is less than a preset first level.

[0086] According to an embodiment, the processor 120 may determine to transmit a wireless signal using the antenna with the relatively larger maximum power value satisfying the specific absorption rate (SAR) of the first antenna 501 and the second antenna 503, based on the fact that the difference between the maximum power value satisfying the specific absorption rate (SAR) of the first antenna 501 and the maximum power value satisfying the specific absorption rate (SAR) of the second antenna 503 exceeds a specified level.

[0087] According to an embodiment, the processor 120 can determine that the second antenna 503 is an antenna for transmitting wireless signals based on the specific absorption rate (SAR) of the transmit power via the first antenna 501 exceeding a specified value.

[0088] According to an embodiment, the processor 120 can determine that the first antenna 501 is an antenna for transmitting wireless signals based on the fact that the amplitude of the transmission power via the second antenna 503 is equal to the amplitude of the maximum power of the electronic device 101.

[0089] According to an embodiment, when transmitting power via the second antenna 503, the processor 120 may change the antenna used to transmit wireless signals to the first antenna based on the fact that the maximum power value of the specific absorption rate (SAR) of the second antenna 503 is less than a preset first level.

[0090] According to an embodiment, the processor 120 can change the antenna used to transmit wireless signals based on the difference between the maximum power value of the specific absorption rate (SAR) on the first antenna 501 and the maximum power value of the specific absorption rate (SAR) on the second antenna 503 exceeding a specified level.

[0091] Figure 6a The communication via Wi-Fi according to a comparative embodiment is shown. Figure 6bAn embodiment is shown that uses methods other than antenna switching to prevent fallback in the case of communication via Wi-Fi.

[0092] exist Figure 6a and Figure 6b In the graph, the X-axis represents time, and the Y-axis represents the intensity of the received power. According to an embodiment, due to the short transmission frequency in environments using VoLTE calls and Wi-Fi, electronic devices (e.g., Figure 1 The electronic device 101 may consume more power. When the power consumption on the antenna of the electronic device 101 exceeds a specified level, backoff can occur to satisfy SAR. Backoff operation can refer to operation where the electronic device 101 is not used at maximum power for stable operation, but rather the power is limited to a point below a certain level (e.g., -3dB). When backoff operation occurs, the transmit power may be insufficient, and therefore communication may not be smooth. The processor (e.g., Figure 1 The processor 120 can replace the antenna used for transmission to maintain smooth communication. Figure 5 The document describes the process of replacing the antenna used for transmission to maintain smooth communication.

[0093] according to Figure 6b The processor 120 can reduce the Wi-Fi transmission frequency or limit the amount of data transmitted via Wi-Fi based on the fact that the amplitude of the transmit power through the antenna in use is equal to the amplitude of the maximum power of the electronic device 101. The processor 120 can reduce the Wi-Fi transmission frequency to reduce power consumption on the antenna and prevent fallback. Alternatively, the processor 120 can limit the amount of data transmitted via Wi-Fi to reduce power consumption on the antenna and prevent fallback.

[0094] When the SAR margin becomes insufficient due to the continuous Tx of the WLAN, the electronic device 200 using WWAN+WLAN time-averaged SAR may experience SAR backoff in the WWAN. The frequency of SAR backoff may increase when the WWAN and WLAN use the same antenna on the electronic device 200.

[0095] When the WWAN is in a call state such as VoLTE or VoNR, WWAN fallback may occur due to WLAN SAR consumption. Fallback can lead to radio link failure (RLF) or mute. The processor 120 can adjust the Wi-Fi transmission frequency to prevent fallback.

[0096] According to an embodiment, processor 120 can pre-determine priorities based on the data type transmitted via Wi-Fi (e.g., AC_VO (video), AC_VI (voice), AC_BE (internet), AC_BK (background data)). Processor 120 can limit the transmission of data with relatively low priority based on whether the amplitude of the transmit power transmitted via the antenna in use exceeds a specified level. The specified level of transmit power amplitude can vary according to configuration. The priority of the data type transmitted via Wi-Fi can also vary according to configuration.

[0097] Processor 120 may be based on electronic device 200 in the first antenna (e.g., Figure 5 The difference between the maximum power value that the first antenna 501 can have and the maximum power value that satisfies the specific absorption rate (SAR) on the first antenna 501 exceeds a specified level to reduce the transmission frequency of Wi-Fi, thereby reducing the power consumption on the antenna.

[0098] Figure 7 A method for changing the transmitting antenna path of an electronic device according to an embodiment is shown sequentially.

[0099] Reference Figure 7 The described operations can be based on data that can be stored on a computer recording medium or memory (e.g., Figure 1 The method 700 shown can be implemented using instructions in memory 130. (Referring to the above...) Figures 1 to 6b The described electronic device (e.g., Figure 1 The electronic device 101) performs the operation, and the above-mentioned technical features will be omitted below. It can be modified. Figure 7 The order of each operation can be adjusted, some operations can be omitted, and some operations can be performed simultaneously.

[0100] In operation 710, the processor (e.g., Figure 1 The processor 120 can be based on satisfying the first antenna (e.g., Figure 5 The maximum power value of the specific absorption rate (SAR) on the first antenna 501 and the electronic device determine the antenna to be used based on the maximum power value of the first antenna 501.

[0101] For example, processor 120 can determine the second antenna (e.g., based on the difference between the maximum power value that the electronic device can have on the first antenna 501 and the maximum power value that satisfies the specific absorption rate (SAR) on the first antenna 501 exceeding a specified level, or based on the occurrence of an event that causes the difference in the maximum power value. Figure 5The second antenna 503 is an antenna used to transmit wireless signals. The event may include, for example, a receiver (RCV) using a microphone in a voice call scenario. The difference between the maximum power value that the electronic device can have on the first antenna 501 and the maximum power value that satisfies the specific absorption rate (SAR) on the first antenna 501 can be a value obtained by subtracting Plimit from Pmax.

[0102] Pmax may include the maximum power value that the electronic device 101 can have on the first antenna 501. The average power limit may include the maximum power value that satisfies the specific absorption rate (SAR) on the first antenna 501. The processor 120 may determine that the second antenna 503 is an antenna for transmitting radio signals based on the value obtained by subtracting the average power limit from Pmax exceeding a specified value (e.g., 10 dB). Conversely, in the case of transmitting signals via the second antenna 503, the processor 120 may determine that the first antenna 501 is an antenna for transmitting radio signals based on the value obtained by subtracting the average power limit from Pmax of the second antenna 502 exceeding a specified value (e.g., 10 dB).

[0103] In operation 720, processor 120 may determine the antenna to be used based on the difference between the maximum power value that satisfies the specific absorptivity (SAR) on the first antenna 501 and the maximum power value that satisfies the specific absorptivity (SAR) on the second antenna 503.

[0104] Processor 120 can change the antenna used to transmit wireless signals based on the difference between the maximum power value satisfying the specific absorption rate (SAR) on the first antenna 501 and the maximum power value satisfying the specific absorption rate (SAR) on the second antenna 503 exceeding a specified level. Figure 7 In the text, operations 710 and 720 are described in sequence, but the order of each operation can be changed, and only one of operations 710 and 720 can be executed.

[0105] Figure 8a and Figure 8b This is a flowchart illustrating the conditions for changing the transmitting antenna path of an electronic device according to an embodiment.

[0106] refer to Figure 8a and Figure 8b The described operations can be based on data that can be stored on a computer recording medium or memory (e.g., Figure 1 The method is implemented using instructions in memory 130. The method shown can be derived from the above reference. Figures 1 to 6b The described electronic device (e.g., Figure 1 The electronic device 101) performs the operation, and the above-mentioned technical features will be omitted below. It can be modified. Figure 8a and Figure 8bThe order of each operation can be adjusted, some operations can be omitted, and some operations can be performed simultaneously.

[0107] In operation 810, the processor (e.g., Figure 1 The processor 120 can determine whether Plimit is less than a specified level (e.g., 13 dB) or whether the value obtained by subtracting Plimit from Pmax exceeds a specified level (e.g., 8 to 10 dB). The specified level is just an example and can vary depending on the configuration.

[0108] Pmax may include the maximum power value that the electronic device 101 can have on the first antenna 501. Plimit may include the maximum power value that satisfies the specific absorption rate (SAR) on the first antenna 501.

[0109] Processor 120 can determine that second antenna 503 is an antenna for transmitting wireless signals based on the value obtained by subtracting Plimit from Pmax exceeding a specified value (e.g., 10 dB). Conversely, in the case of transmitting signals via second antenna 503, processor 120 can determine that first antenna 501 is an antenna for transmitting wireless signals based on the value obtained by subtracting Plimit from Pmax exceeding a specified value (e.g., 10 dB).

[0110] In operation 812, processor 120 may change the antenna connected to electronic device 101 based on Plimit being less than a specified level (e.g., 13 dB) or by subtracting Plimit from Pmax and obtaining a value that exceeds a specified level (e.g., 8 to 10 dB) (operation 810 - Yes).

[0111] In operation 810, processor 120 may perform operation 820 (operation 810-No) based on Plimit exceeding a specified level (e.g., 13 dB) or by subtracting Plimit from Pmax and obtaining a value less than a specified level (e.g., 8 dB to 10 dB).

[0112] In operation 820, according to an embodiment, processor 120 can confirm the conditions for changing the antenna. For example, it can be determined whether the sum of the difference between the RSRP values ​​of the first antenna 501 and the second antenna 503 and the difference between the maximum transmit power values ​​of the first antenna 501 and the second antenna 503 exceeds a specified level.

According to an embodiment, in the case of time-averaged SAR (TSA), Plimit may include a maximum power value configured based on the value of the average power measured over a specific time period.

[0116] In operation 832, processor 120 can determine that the second antenna 503 is an antenna to be connected based on whether the value obtained by subtracting the Plimit value of the first antenna 501 from the Plimit value of the second antenna 503 exceeds a specified level (operation 830 - Yes). When processor 120 is connected to the second antenna 503, processor 120 can determine that the first antenna 501 is an antenna to be connected to electronic device 101 based on whether the value obtained by subtracting the Plimit value of the second antenna 503 from the Plimit value of the first antenna 501 exceeds a specified level.

[0122] Figure 9a and Figure 9b This is a flowchart illustrating the conditions for changing the transmitting antenna path of an electronic device according to an embodiment.

[0123] refer to Figure 9a and Figure 9b The described operations can be based on data that can be stored on a computer recording medium or memory (e.g., Figure 1 The method is implemented using instructions in memory 130. The method shown can be referenced above. Figures 1 to 6b The described electronic device (e.g., Figure 1 The electronic device 101) performs the operation, and the above-mentioned technical features will be omitted below. It can be modified. Figure 9a and Figure 9b The order of each operation can be adjusted, some operations can be omitted, and some operations can be performed simultaneously.

[0124] In operation 910, the processor (e.g., Figure 1 The processor 120 can determine whether Plimit is less than a specified level (e.g., 13 dB) or whether the value obtained by subtracting Plimit from Pmax exceeds a specified level (e.g., 8 to 10 dB). The specified level is just an example and can vary depending on the configuration.

[0125] Pmax may include the maximum power value that the electronic device 101 can have on the first antenna 501. Plimit may include the maximum power value that satisfies the specific absorption rate (SAR) on the first antenna 501.

[0126] Processor 120 can determine that second antenna 503 is an antenna for transmitting wireless signals based on the value obtained by subtracting Plimit from Pmax exceeding a specified value (e.g., 10 dB). Conversely, in the case of transmitting signals via second antenna 503, processor 120 can determine that first antenna 501 is an antenna for transmitting wireless signals based on the value obtained by subtracting Plimit from Pmax exceeding a specified value (e.g., 10 dB).

[0127] In operation 912, processor 120 may change the antenna connected to electronic device 101 based on Plimit being less than a specified level (e.g., 13 dB) or by subtracting Plimit from Pmax and obtaining a value that exceeds a specified level (e.g., 8 to 10 dB) (operation 910 - Yes).

[0128] In operation 910, processor 120 may perform operation 920 (operation 910-No) based on Plimit exceeding a specified level (e.g., 13dB) or by subtracting Plimit from Pmax and obtaining a value less than a specified level (e.g., 8dB to 10dB).

[0129] In operation 920, processor 120 can determine whether the sum of the difference between the RSRP values ​​of the first antenna 501 and the second antenna 503 and the difference between the maximum transmit power values ​​of the first antenna 501 and the second antenna 503 exceeds a specified level.

[0130] In operation 922, processor 120 may determine whether to change the connected antenna based on the sum of the difference between the RSRP value between the first antenna 501 and the second antenna 503 and the difference between the maximum transmit power value, which exceeds a certain value (operation 920 - Yes).

[0131] Processor 120 may perform operation 930 (operation 920-No) based on the fact that the sum of the difference between the RSRP values ​​between the first antenna 501 and the second antenna 503 and the difference between the maximum transmit power values ​​does not exceed a specific value.

[0132] In operation 930, processor 120 can determine whether the amplitude of the SAR exceeds a certain level for a specified time. Specific absorptivity (SAR) can refer to the electromagnetic wave absorptivity. Specific absorptivity (SAR) can also refer to the rate at which energy is absorbed per unit mass of biological tissue (W / kg). When the amplitude of the SAR exceeds a certain level, the electronic device 101 can perform a backoff because the electromagnetic waves may have a significant and potentially harmful effect on the human body. When the electronic device 101 performs a backoff, the transmission power can be reduced, which may result in muteness or uneven data transmission. To prevent the electronic device 101 from performing a backoff, the transmitting antenna can be replaced with another antenna.

[0133] Electronic device 101 may include a time-averaged SAR (TAS) that controls the amplitude of the SAR based on an average value, ensuring that the SAR amplitude does not exceed a specific level within a given time period. For example, electronic device 101 may measure power within a certain time period and change the average maximum power value, which alters the maximum power value of the SAR. In the case of electronic device 101 operating based on TAS, electronic device 101 can control the TAS from triggering a backoff operation by changing the maximum average power value of the TAS (i.e., an average power limit).

[0134] In operation 932, processor 120 may determine whether to change the connected antenna based on the SAR amplitude exceeding a certain level (operation 930 - Yes). Processor 120 may terminate the antenna switching operation based on the SAR amplitude not exceeding a certain level (operation 930 - No).

[0135] Reference Figure 9b In operation 940, processor 120 may determine whether the maximum average power value (i.e., the average power limit) is less than a specified level (e.g., 13 dB), or whether the value obtained by subtracting the maximum average power value (i.e., the average power limit) from Pmax exceeds a specified level (e.g., 8 to 10 dB). The specified level is merely an example and may vary depending on the configuration.

[0136] Processor 120 can determine that second antenna 503 is an antenna for transmitting wireless signals based on a value obtained by subtracting the maximum average power value (i.e., the average power limit) from Pmax exceeding a specified value (e.g., 10 dB). Conversely, in the case of transmitting signals via second antenna 503, processor 120 can determine that first antenna 501 is an antenna for transmitting wireless signals based on a value obtained by subtracting the maximum average power value (i.e., the average power limit) from Pmax exceeding a specified value (e.g., 10 dB).

[0137] In operation 942, processor 120 may change the antenna connected to electronic device 101 based on the maximum average power value (i.e., average power limit) being less than a specified level (e.g., 13 dB) or the value obtained by subtracting the maximum average power value (i.e., average power limit) from Pmax being greater than a specified level (e.g., 8 to 10 dB) (operation 940 - yes).

[0138] In operation 940, processor 120 may perform operation 950 (operation 940-No) based on the maximum average power value (i.e., the average power limit (Plimit)) exceeding a specified level (e.g., 13 dB) or by subtracting the maximum average power value (i.e., the average power limit) from Pmax and obtaining a value less than a specified level (e.g., 8 to 10 dB).

[0139] In operation 950, processor 120 can determine whether the sum of the difference between the RSRP values ​​of the first antenna 501 and the second antenna 503 and the difference between the maximum transmit power values ​​of the first antenna 501 and the second antenna 503 exceeds a specified level.

[0140] In operation 952, processor 120 may determine whether to change the connected antenna based on the sum of the difference between the RSRP value between the first antenna 501 and the second antenna 503 and the difference between the maximum transmit power value, which exceeds a certain value (operation 950 - Yes).

[0141] Processor 120 may perform operation 960 (operation 950-No) based on the fact that the sum of the difference between the RSRP values ​​between the first antenna 501 and the second antenna 503 and the difference between the maximum transmit power values ​​does not exceed a specific value.

[0142] In operation 960, processor 120 can determine whether the transmit power of the antenna is equal in amplitude to the maximum power that electronic device 101 can apply to the antenna. When the transmit power of the antenna is equal in amplitude to the maximum power that electronic device 101 can apply to the antenna, electronic device 101 can perform a fallback due to high power consumption. When electronic device 101 performs a fallback, the transmit power can be reduced, which may result in mute or uneven data transmission. To prevent electronic device 101 from performing a fallback, the transmit antenna can be replaced with another antenna.

[0143] In operation 962, processor 120 may determine whether to change the connected antenna based on the fact that the transmit power of the antenna is equal in magnitude to the maximum power that the electronic device 101 can apply to the antenna (operation 960 - Yes). Processor 120 may terminate the antenna switching operation based on the fact that the transmit power of the antenna is not equal in magnitude to the maximum power that the electronic device 101 can apply to the antenna (operation 960 - No).

[0147] According to an embodiment, the processor can determine the SAR margin by subtracting the current power value from the maximum average power value that satisfies the SAR requirement. The processor can then determine the time until the current power reaches the maximum average power and a backoff operation occurs based on the SAR margin. The processor can determine that a larger SAR margin results in a longer remaining time until a backoff operation occurs.

[0148] According to an embodiment, when transmitting a signal via the first antenna, the processor determines the second antenna as the antenna for transmitting the signal based on the fact that the amplitude of the maximum power of the signal output via the first antenna, which satisfies the specific absorption rate (SAR) configured in the electronic device, is less than a preset first level.

[0149] According to an embodiment, the processor can determine to use the antenna with a relatively larger amplitude of the maximum power of the output signal satisfying the specific absorption rate (SAR) of the first antenna and the second antenna to transmit a wireless signal based on the difference between the amplitude of the maximum power of the signal satisfying the specific absorption rate (SAR) configured in the electronic device and the amplitude of the maximum power of the signal satisfying the specific absorption rate (SAR) configured in the electronic device exceeding a specified level.

[0150] According to an embodiment, the processor can determine to use the second antenna output signal based on the amplitude of the signal output via the first antenna exceeding a first level. The first level can be determined as a value representing a specific ratio of the amplitude of the maximum power of the signal output via the first antenna that satisfies the specific absorptivity (SAR) configured in the electronic device.

[0151] According to an embodiment, the processor can determine whether to use the first antenna to output a signal based on the amplitude of the signal output via the second antenna being equal to the amplitude of the maximum transmit power level of the signal output via the second antenna.

[0152] According to an embodiment, in the case of transmitting power via the second antenna, the processor can determine to use the first antenna to output a signal based on the fact that the amplitude of the maximum power of the signal output via the second antenna that satisfies the specific absorption rate (SAR) configured in the electronic device is less than a preset level.

[0153] According to an embodiment, the processor can reduce the Wi-Fi transmission frequency or limit the amount of data transmitted via Wi-Fi based on the fact that the amplitude of the signal output via at least one of the first antenna and the second antenna is equal to the maximum transmit power level.
