Description

Electronic device for changing antenna settings and method of operation thereof

[0001] Various embodiments of the present disclosure relate to an electronic device for changing antenna settings and a method of operating the same.

[0002] User equipment (UE) can transmit electromagnetic waves to transmit and receive data with a base station. The electromagnetic waves emitted by UE can have harmful effects on the human body, and various domestic and international organizations are attempting to limit the electromagnetic waves that have harmful effects on the human body. For example, the specific absorption rate (SAR) is a numerical value that indicates how much electromagnetic waves emitted from a mobile communication terminal are absorbed by the human body. SAR uses the unit of kW / g (or mW / g), which can mean the amount of power (kW, watt, or milliwatt) absorbed per 1 gram of body mass. As concerns about the harmful effects of electromagnetic waves on the human body have emerged, SAR limits for mobile communication terminals have been established.

[0003] The user device may back off the transmit power, maximum transmit power level (MTPL), if, for example, the expected SAR based on the transmit power is expected to exceed a threshold. For example, when the user device detects the occurrence of a specific event (e.g., grip, hot-spot, or proxy), the user device may transmit an RF signal at the back off power corresponding to the event, or transmit an RF signal at a transmit power set based on the backed off maximum transmit power level.

[0004] In addition, a technology for backing off the transmission power (or maximum transmission power level) based on the total amount of SAR values ​​accumulated over a certain period of time (or the average value of SAR generated over a certain period of time) is also being utilized. SAR that affects the human body instantaneously and / or SAR that affects the human body on average must also be considered, and accordingly, backing off the transmission power (or maximum transmission power level) can be performed when the total amount of accumulated SAR values ​​(or the average value of SAR generated over a certain period of time) satisfies a specified condition.

[0005] The total amount of SAR accumulated for each of a plurality of antennas can be managed, and accordingly, a maximum transmission power level can be set for each of the plurality of antennas. The user device can determine whether to change the transmission antenna based on the reception strength and / or the maximum transmission power level corresponding to each of the plurality of antennas. For example, the user device can change the transmission antenna from the first antenna to the second antenna if the reception strength and / or the maximum transmission power level corresponding to the first antenna determined as the transmission antenna and the reception strength and / or the maximum transmission power level corresponding to the second antenna satisfy a transmission antenna changing condition.

The operations may include identifying, based on the first parameter information and the second parameter information, whether a first switching condition associated with changing a transmission antenna to the second antenna is satisfied. The operations may include changing the transmission antenna to the second antenna upon determining that the first switching condition is satisfied. The above operations may include an operation of determining whether a second switching condition associated with periodic switching of the transmission antenna is satisfied based on the first parameter information upon determining that the first switching condition is not satisfied. The above operations may include an operation of performing periodic switching of the transmission antenna based on a first scheduling ratio of the first antenna for a first switching period upon determining that the second switching condition is satisfied.

The operations may include an operation of checking whether a first switching condition associated with changing a transmission antenna to the second antenna is satisfied based on the first parameter information and the second parameter information. The above operations may include, upon confirming that the first switching condition is satisfied, changing the transmitting antenna to the second antenna. The above operations may include, upon confirming that the first switching condition is not satisfied, confirming whether a second switching condition associated with periodic switching of the transmitting antenna is satisfied based on the first parameter information. The above operations may include, upon confirming that the second switching condition is satisfied, performing periodic switching of the transmitting antenna based on a first scheduling ratio of the first antenna for a first switching period.

[0047] The first communication processor (212) may establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and may support legacy network communication through the established communication channel. According to various embodiments, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor (214) may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294), and may support 5G network communication through the established communication channel. According to various embodiments, the second cellular network (294) may be a 5G network defined by the 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0048] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) via the processor-to-processor interface (213). The above interprocessor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express) interface), but there is no limitation on its type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using, for example, a shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output intensity, and resource block (RB) allocation information, with the second communication processor (214).

[0049] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data with the second communication processor (214) through the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface.

[0051] 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 single package may include a memory (or storage means) that stores instructions that cause the performance of at least some of the operations performed according to various embodiments, and a processing circuit (or, the name thereof is not limited, such as an arithmetic circuit) for executing the instructions.

[0052] The first RFIC (222) may, upon transmission, convert a baseband signal generated by the first communication processor (212) into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in a first cellular network (292) (e.g., a legacy network). Upon reception, the RF signal may be acquired from the first network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a baseband signal so that it may be processed by the first communication processor (212).

[0053] The second RFIC (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the preprocessed 5G Sub6 RF signal may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0054] The third RFIC (226) can convert the baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network (294) (e.g., 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., antenna (248)) and preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) can be formed as a part of the third RFIC (226).

[0055] The electronic device (101) may, according to one embodiment, include a fourth RFIC (228) separately from or at least as a part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular 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) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0056] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to various embodiments, when the first RFIC (222) and the second RFIC (224) in FIG. 2A or FIG. 2B are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to one of the first RFFE (232) and the second RFFE (234). According to one 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 example, at least one antenna module among the first antenna module (242) or the second antenna module (244) can be omitted or combined with another antenna module to process RF signals of corresponding multiple bands.

[0057] According to one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the bottom surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the top surface) to form the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce, for example, the loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communications by the transmission line. Due to this, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0058] According to an exemplary 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, for example, as part of the third RFFE (236). Upon transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. Upon reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the external source.

[0059] The second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in connection with (e.g., Non-Stand Alone (NSA)) the first cellular network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network after accessing the access network of the 5G network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication 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)).

[0060] FIG. 3A illustrates a flowchart for explaining an operation method of an electronic device according to various embodiments. The embodiment of FIG. 3A will be described with reference to FIG. 3B and FIGS. 4A to 4E. FIG. 3B is a diagram for explaining transmission power and SAR over time according to various embodiments. FIGS. 4A to 4C illustrate graphs of transmission power over time according to various embodiments. FIGS. 4D to 4E illustrate tables of transmission power over time according to various embodiments.

[0061] According to various embodiments, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)) may call (or read) multiple tables for transmission power corresponding to multiple points in time in operation 301. Before describing the embodiment associated with FIG. 3A, terms such as those in Table 1 are defined.

[0062] a. Normal MAX Power: The maximum transmission power when the SAR margin remains. b. Normal Max SAR: The SAR value that occurs when operating at Normal MAX Power. c. Backoff MAX Power: The maximum transmission power when backoff is performed due to insufficient SAR margin. d. Backoff Max SAR: The SAR value that occurs when operating at Backoff Max Power. e. Measurement Time (T): The period for calculating the accumulated SAR, or calculating the average of the SAR. f. Measurement Period (P): The cycle (or time interval) for calculating the SAR. g. The number of tables for calculating SAR: T / P - 1h. Average SAR LIMIT: The maximum average SAR value that should not be exceeded during T. i. Average Time (A_Time): The time measured by accumulating SAR. j. Accumulated SAR: The sum of SAR accumulated during the Average Time. k. Max Accumulated SAR: Average SAR LIMIT X measurement Time. l. Average SAR: The value of the average SAR used during the Average Time. m. Tx Room: Max accumulated SAR - accumulated SAR, remaining SARn. Remain Time (R_Time): Total measurement time - SAR measurement time up to now (A_Time)

[0063] First, for an explanation of the table, reference will be made to FIGS. 4A to 4C. Referring first to FIG. 4A, a graph including transmission power for a plurality of time points (401 to 449) is illustrated. The cumulative SAR (cumulative SAR in Table 1) during a measurement time (Measurement time in Table 1), for example, a measurement time including 50 time points, may need to be maintained at a value less than or equal to a maximum cumulative SAR (Max cumulative SAR in Table 1). The electronic device (101) may determine the transmission power of an RF signal to be transmitted at the current time point (449) such that, in addition to the cumulative SAR at the current time point (449) and any past time points (409 to 448) (e.g., Average Time in Table 1), the cumulative SAR of additional nine future time points (not shown) (e.g., Remain Time in Table 1) remains less than or equal to the maximum cumulative SAR. In addition, the electronic device (101) can check the transmission powers (452) shifted by 1 from the transmission powers (451) at the current point in time (449) and any past points in time (409 to 448) of FIG. 4A, as in FIG. 4B. The fact that the point in time is shifted by 1 may mean that data at the most recent point in time (e.g., point 409 in FIG. 4A) is not reflected. The number of transmission powers (452) at the current point in time (449) and any past points in time (410 to 448) may be 40, which may be 1 less than the number of transmission powers (451) of FIG. 4A, which is 41. The electronic device (101) can determine the transmission power at the current point in time (449) so that the sum of the SAR by the transmission powers (452) and the predicted SAR at an additional 10 future points in time remains less than the maximum cumulative SAR. As in FIG. 4c, the electronic device (101) can check the transmission powers (453) at the current point in time (449) shifted by 25 from the transmission powers (451) and at any point in time (434 to 448) in the past.The number of transmission powers (453) may be 16, which may be 25 less than the number of transmission powers (451) of FIG. 4A, which is 41. The electronic device (101) may determine the transmission power at the current time point (449) so that the sum of the SAR by the transmission powers (453) and the predicted SAR at additional 34 future time points remains less than or equal to the maximum cumulative SAR. Although not shown, the electronic device (101) may manage a plurality of graphs shifted by one time point. The period for calculating the SAR may be, for example, the interval between the transmission powers in FIGS. 4A to 4C, which is the measurement period (P) of Table 1. The electronic device (101) can calculate and / or manage T / P - 1 tables for a specific point in time. Hereinafter, a configuration for checking a SAR prediction value will be described with reference to FIGS. 4D and 4E. Referring to FIG. 4D, the electronic device (101) can check a k-th SAR table (460). The k-th SAR table (460) can include D1, which is a SAR accumulation value (461) at at least one past point in time, a maximum SAR value (462) (D2) at the current point in time, and a SAR prediction value (463) (D3) at at least one future point in time. Referring to the graph, the accumulation value of SAR corresponding to at least one past point in time (461) can be D1. D1, which is a SAR accumulation value (461) at at least one past point in time, can be checked based on an antenna setting. The number of at least one past time point may be one less than the total number of time points (e.g., 100) corresponding to the measurement time (e.g., 50 seconds) in the first table. The total number of time points (e.g., 100), N, may be the result of dividing the measurement time by the sampling interval (or shift interval). Accordingly, in the k-th table, the number of at least one past time point may be k less than the total number of time points.The electronic device (101) can check the SAR cumulative value D1 of Nk past points in time (471). The electronic device (101) can use the maximum value S1 of the SAR for the current point in time (472). The maximum value S1 (e.g., normal max SAR in Table 1) of the SAR can be a SAR value corresponding to the maximum transmission power specified in the electronic device (101) (e.g., normal max power in Table 1). In one embodiment, the SAR value immediately before the current point in time (472) can be used for the current point in time (472). In one embodiment, the SAR average value of past points in time (471) of the current point in time (472) can be used for the current point in time (472). The electronic device (101) can calculate the sum of the SAR values ​​(S2) (e.g., backoff max SAR in Table 1) for the backed-off transmission power (e.g., backoff max power in Table 1) for at least one future time point (473). The electronic device (101) can check D3 as the cumulative SAR for at least one future time point (473). In the k-th table, the number of at least one future time point may be k-1. Accordingly, the electronic device (101) can check whether the sum of the SARs for N time points, which are composed of Nk past time points, 1 current time point, and k-1 future time points, (D1+D2+D3) exceeds the maximum cumulative SAR. If it is confirmed to exceed, the electronic device (101) can backoff the transmission power of the current time point. Referring to FIG. 4e, the electronic device (101) can also check the k+1th table (480) as in FIG. 4e. The electronic device (101) can check, in the k+1th table (480), that the SAR cumulative value (481) of at least one past point in time is D4, that the SAR maximum value (482) of the current point in time is D2, and that the SAR predicted value (483) of at least one future point in time is D5.The electronic device (101) can check whether the SAR accumulation value of D4 + D2 + D5 exceeds the maximum accumulated SAR. In the k+1-th table, the number of at least one past time point (491) may be 1 less than the number of at least one past time point (471) in the k-th table. In the k+1-th table, the number of at least one future time point (493) may be 1 (494) greater than the number of at least one future time point (473) in the k-th table.

[0064] According to various embodiments, in operation 303, the electronic device (101) may check the past SAR cumulative value, the current time point, and the SAR predicted value at the future time point for a plurality of tables corresponding to at least one future time point. The electronic device (101) may check the SAR cumulative value for the first table and a total of N-1 tables that are shifted by time point i (i is 1 or more and less than N-2) from the first table. In operation 305, the electronic device (101) may check whether there is a table in which the sum of the SAR cumulative value and the SAR predicted value exceeds a threshold. If there is a table exceeding the threshold (305-Yes), in operation 307, the electronic device (101) may back off any one of the transmission powers of at least a portion of the RF signal (or at least a portion of the maximum transmission power limit (MTPL)). Those skilled in the art will appreciate that the back-off of the transmission power in this document may be replaced with a back-off of the maximum transmission power level. If there is no table exceeding the threshold (305-No), the electronic device (101) may transmit an RF signal at the set transmission power in operation 309. In various embodiments of the present disclosure, the backoff of the maximum value of the transmission power may mean the backoff of the maximum value of the transmission power.

[0065] As described above, the electronic device (101) can determine the maximum value of the transmission power so that the average value of the SAR used during the measurement time does not exceed the Average SAR limit. Alternatively, the electronic device (101) can determine the maximum value of the transmission power so that the accumulated SAR during the measurement time does not exceed the Max accumulated SAR. The electronic device (101) can determine the maximum value of the maximum power for the next time interval every P hours. For example, the conditions for operating at the normal max power during the next P hours can be as follows.

[0066] Condition: Tx Room > Occurrence SAR when operating at normal max power for the next P (normal max SAR in Table 1) + Occurrence SAR when operating at backoff max power for (Remain Time - P) (backoff max SAR in Table 1) = PX normal max SAR + (Remain Time - P) X backoff max SAR

[0067] The Tx Room in the condition may be a value obtained by subtracting the accumulated SAR up to the present from the Max accumulated SAR. The (Remain Time - P) in the condition may be T - average time - P, and may be, for example, a future time as described in FIGS. 4a to 4e. P may mean a present time. Average time may mean a past time. Satisfaction of the condition may mean that even if the electronic device (101) sets the maximum transmission power of the normal max power for the P time, there is no table in which the accumulated SAR exceeds the Max accumulated SAR. Non-satisfaction of the condition may mean that if the electronic device (101) sets the maximum transmission power of the normal max power for the P time, there is a possibility that there is a table in which the accumulated SAR exceeds the Max accumulated SAR, in which case, the electronic device (101) may set the backoff max power to the maximum transmission power for the P time.

[0068] Table 2 shows examples of variables and conditions.

[0069] [Example of variable settings]i. Normal MAX Power: 23dBmii. Backoff MAX Power: 20dBmiii. Measurement Time(T): 100 secondsiv. Measurement Period(P): 0.5 secondsv. Number of SAR Calculator tables: 199vi. Average SAR LIMIT: 1.5mW / gvii. Max cumulative SAR: 150mW / gviii. When Normal Max SAR => 23dBm, SAR: 2mW / gix. Backoff Max SAR => SAR when 20dBm: 1mW / g [the point at which the maximum power switches from normal max power to backoff max power] Average time X normal max power + (100 - average time) X backoff max power <= the point at which the accumulated max SAR is satisfied = Average time X 2 mW / g + (100 - average time) X 1mW / g <= 150 mW / g<=> Average time <=50

[0070] In the example in Table 2, it is explained that continuous use of normal max power with maximum transmit power is possible for 50 seconds, and backoff to backoff max power is required after 50 seconds. For example, let's assume that an RF signal is transmitted at normal max power of 23 dBm for 50 seconds, then an RF signal is transmitted at normal max power of 23 dBm for the next P (0.5 seconds), and then an RF signal is transmitted at backoff max power of 20 dBm for (Remain time - P) 49.5 seconds. In this case, Tx Room can be 50 mW / g, which is 150 mW / g - 50 X 2 mW / g. The SAR occurrence during P time can be 1 mW / g, which is 2 mW / g X 0.5 seconds. The SAR occurrence of (Remain time - P) can be 49.5 mW / g, which is 49.5 seconds X 1 mW / g. At this time, it can be confirmed that the accumulated SAR during P and (Remain time - P) exceeds the Tx room by 50.5 mW / g, which ultimately requires a backoff of the maximum value of the transmission power at the time point P. The above-described example will be described with reference to FIG. 3b, which illustrates the transmission power associated with one RAT. For example, referring to FIG. 3b, it can be confirmed that the maximum transmission power can be set to the normal max power (351) until A seconds (e.g., 50 seconds), but is backed off to the backoff max power (352) after A seconds. Depending on the backoff of the maximum value of the maximum transmission power, the slope of the second part (362) of the accumulated SAR can be formed smaller than the slope of the first part (361) of the accumulated SAR. The average SAR (331) before A second exceeds the average SAR limit (340), but at 100 seconds according to the backoff, it can be confirmed that the average SAR (332) is equal to the value of the average SAR limit (340).FIG. 5A illustrates a block diagram for explaining an exemplary electronic device according to various embodiments. The embodiment of FIG. 5A will be described with reference to FIG. 5B. FIG. 5B is a diagram for explaining an exemplary electronic device according to various embodiments. According to various embodiments, a communication processor (501) (e.g., at least one of the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)) may transmit a baseband signal to an RFIC (503) (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)) and / or receive a baseband signal. The RFIC (503) may process at least one RF signal associated with at least one RF path. Here, the RF path may include, for example, at least one hardware for transmitting an RF signal (e.g., at least one of an RFIC, an RFFE, or an antenna). For example, RFIC (503) can receive at least one baseband signal from communication processor (501) and can generate at least one RF signal. Although RFIC (503) is illustrated as one module in the example of FIG. 5A, it will be understood by those skilled in the art that this is exemplary and that there is no limitation on the number of modules in which RFIC (503) is implemented.

[0071] According to various embodiments, the RFIC (503) may provide at least one RF signal to the first RFFE (505) and / or the second RFFE (507). The first RFFE (505) and / or the second RFFE (507) may process (e.g., amplify) the received RF signal and provide the processed RF signal. The communication processor (501) may determine the amplification degree of the RFFEs (505, 507) based on the maximum transmit power level and / or transmit power determined as described above. Although not shown, the amplification degree of the RFFEs (505, 507) may be controlled based on an average power tracking (APT) module and / or an envelope tracking (ET) module. According to various embodiments, one RFFE may process a plurality of RF signals.

[0072] According to various embodiments, the first RFFE (505) may be connected to a single pole double throw (SPDT) switch (509), and an output terminal of the SPDT switch (509) may be connected to a switch (511). The switch (511) may be configured to selectively connect the output terminal of the SPDT switch (509) to either the first antenna (521) or the second antenna (522). The second RFFE (507) may be connected to a switch (513). The switch (513) may be configured to selectively connect the output terminal of the second RFFE (507) to either the SPDT switch (509), the third antenna (523), or the fourth antenna (524). In one embodiment, each of the antennas (521, 522, 523, 524) may be disposed within the housing and / or may be disposed on a portion of the housing. For example, they may be disposed on an outer surface of the housing of the electronic device (101), but are not limited thereto. In one example, as shown in FIG. 5B, the antennas (521, 522) may be disposed on one side (e.g., the bottom) of the housing of the electronic device (101), and the antennas (523, 524) may be disposed on the other side (e.g., the top) of the housing of the electronic device (101), but this is exemplary.

[0073] For example, whether a violation of a restriction (e.g., a SAR restriction) should be determined based on the sum of the RF radiation (e.g., SAR and / or PD) generated by multiple antennas, or whether each RF radiation generated by multiple antennas should independently be determined to violate the restriction, can be determined by the following mathematical expression 1.

[0074] [Mathematical Formula 1]

[0075]

[0076] In Equation 1, SAR1 is the SAR generated by one antenna, and SAR2 is the SAR generated by another antenna, and the unit may be, for example, W / kg. R for the sum of various SARs may be, for example, as shown in Table 3. Meanwhile, the numbers 1.5 and 0.04 in Equation 1 are merely exemplary and are not limiting.

[0077] Sum of SAR (SAR1+SAR2) (W / Kg)Minimum separation distance (minimum value of R) (mm)3.21432.81172.4932711.6511.4411.2331.0250.818

[0078] For example, let's assume that the sum of SAR generated from two antennas is 3.2 W / Kg. Meanwhile, since both antennas are arranged on the top of the electronic device (101), the separation distance may be less than 143 mm. In this case, in order to determine whether the electronic device (101) violates the instantaneous SAR regulation or the cumulative SAR regulation, it may be necessary to determine whether the sum of SARs generated from the two antennas violates the SAR regulation. To comply with the SAR regulation, for example, the electronic device (101) may perform a backoff associated with the transmission power of an RF signal based on one of the two antennas. Those skilled in the art will understand that the RF radiation in the present disclosure may mean, for example, SAR, PD, TRP (total radiated power), and / or EIRP (effective isotropic radiated power). For example, there is no limitation on the reference point of each antenna for defining the distance between the antennas. The distance between the antennas may be, for example, the minimum physical distance between the antennas. For example, the reference point may be set in various ways, such as the point where the largest RF is generated among the antennas, the center of mass of the antenna, or a point at one end of the antenna, and there is no limitation on the setting method. For example, the separation distance may be 143 mm or more when each of the two antennas is arranged at the bottom and top of the electronic device (101), for example. In this case, in order to determine whether the electronic device (101) violates the cumulative SAR regulation, it may be determined whether the sum of the SARs generated from either of the two antennas violates the SAR regulation and / or whether the sum of the SARs generated from the other of the two antennas violates the SAR regulation.In one embodiment, the antenna (523) located at the top of the electronic device (101) and the antenna (522) located at the bottom may be included in different antenna groups, respectively. Accordingly, the electronic device (101) may independently manage whether to back off based on the RF radiation amount based on the antenna (523) and whether to back off based on the RF radiation amount based on the antenna (522). For example, the electronic device (101) may set the transmitting antenna to the antenna (522) at a first time point. The electronic device (101) may determine whether to back off based on the RF radiation amount of the antenna (522) (e.g., accumulated RF radiation amount at past time points). If the condition for changing the transmitting antenna is satisfied at a second time point, the electronic device (101) may change the transmitting antenna from the antenna (522) to the antenna (523). The electronic device (101) may determine whether to back off after the second time point based on the RF radiation amount of the antenna (523) (e.g., accumulated RF radiation amount at the past time point). Meanwhile, changing the transmission antenna may also be referred to as transmitting antenna switching or transmitting antenna hopping. For example, changing the transmission antenna may be performed based on controlling a switch (e.g., 509, 511, and / or 513) and / or changing an RF component (e.g., a power amplifier (PA)), and there is no limitation on the method. For example, when the communication processor (501) determines that the transmission antenna is to be changed, the communication processor (501) may control at least some of the RF circuits (e.g., RFIC (503), RFFEs (505, 507), and / or switches (e.g., 509, 511, and / or 513)).

[0079] FIG. 6 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0080] According to one embodiment, the electronic device (101) (e.g., the communication processor (501)) may, in operation 601, determine at least one first parameter and at least one second parameter. In one embodiment, the at least one first parameter may include a first reception intensity corresponding to a signal received from a first communication network through a first antenna configured as a transmission antenna of the electronic device (101). The at least one first parameter may include a second reception intensity corresponding to a signal received through a second antenna different from the first antenna. The reception intensity may refer to information associated with the intensity of a signal received through the first antenna. For example, the reception intensity may be expressed as a reference signal received power (RSRP), but this is exemplary and may also be expressed in units such as a signal to noise ratio (SNR), a reference signal received quality (RSRQ), or a received signal strength indicator (RSSI), without limitation. For example, the electronic device (101) is configured to support changing the transmitting antenna between the first antenna and the second antenna, and is configured to assume that the first antenna is set as the transmitting antenna while at least one of operations 601, 603, 607, or 609 is performed. For example, based on the first antenna being the default transmitting antenna, the electronic device (101) may set the first antenna as the transmitting antenna. For example, the electronic device (101) may use the second antenna as the transmitting antenna, and then set the first antenna as the transmitting antenna based on satisfaction of a switching condition associated with the change of the transmitting antenna, and there is no limitation on the manner or time at which the first antenna is set as the transmitting antenna.In one embodiment, at least one second parameter may include a maximum value of a first transmission power corresponding to the first antenna. The at least one second parameter may include a maximum value of a second transmission power corresponding to the second antenna. Here, the maximum value of the transmission power may be, for example, MTPL, but for example, the maximum value of the first transmission power may be set to a smaller value between MTPL and PcMax, and there is no limitation.

[0081] In one embodiment, the electronic device (101) may, in operation 603, determine whether the at least one first parameter and the at least one second parameter satisfy a first switching condition associated with a change of a transmission antenna. If the first switching condition set for changing the transmission antenna is not satisfied (603-No), the electronic device (101) may, in operation 607, determine whether the at least one first parameter satisfies a second switching condition associated with periodic switching of the transmission antenna. If the condition set for changing the transmission antenna to the second antenna is satisfied (603-Yes), the electronic device (101) may, in operation 605, change the transmission antenna to the second antenna. The electronic device (101) may change the setting of the transmission antenna by changing the transmission antenna from the first antenna to the second antenna. For example, the electronic device (101) may determine whether the first switching condition set for changing the transmission antenna as in Equation 2 is satisfied.

[0082] [Equation 2]

[0083] (Second reception strength - First reception strength) + (Maximum value of second transmission power - Maximum value of first transmission power) > First threshold

[0084] As in mathematical expression 2, the electronic device (101) can determine whether the sum of the first difference between the first reception strength and the second reception strength and the second difference between the maximum value of the first transmission power and the maximum value of the second transmission power exceeds (or may be equal to or greater than) a first threshold value, thereby satisfying a condition set for changing the transmission antenna. The difference between the reception strengths may be defined as, for example, a value obtained by subtracting the reception strength corresponding to the antenna set as the transmission antenna from the reception strength corresponding to the antenna not set as the transmission antenna, but there is no limitation thereto. The difference between the maximum values ​​may be defined as, for example, a value obtained by subtracting the maximum value of the transmission power corresponding to the antenna set as the transmission antenna from the maximum value of the transmission power corresponding to the antenna not set as the transmission antenna, but there is no limitation thereto. In one embodiment, a method of determining whether antenna switching is performed based on at least one first parameter and at least one second parameter may be referred to as a "first antenna switching method." The first antenna switching method may be a method that considers the maximum value of the transmission power (or MTPL) associated with the SAR consumption, and may be a method that confirms the performance of antenna switching when the first difference between the first reception intensity and the second reception intensity is relatively large, and / or the SAR consumption of either the first antenna or the second antenna is relatively large.

[0085] In one embodiment, the electronic device (101) may determine whether the at least one first parameter satisfies a second switching condition associated with periodic switching of the transmission antenna based on determining (operation 603 - No) that the at least one first parameter and the at least one second parameter do not satisfy a first switching condition associated with changing the transmission antenna. For example, the electronic device (101) may determine whether the second switching condition set for periodic switching as in Equation 3 is satisfied.

[0086] [Equation 3]

[0087] (2nd reception intensity) & (1st reception intensity) < 1st threshold reception intensity

[0088] As in mathematical expression 3, the electronic device (101) can determine whether the condition set for changing the transmitting antenna is satisfied by determining whether both the first reception intensity and the second reception intensity are less than (or may be less than) the first threshold reception intensity. The electronic device (101) can determine whether the second switching condition is satisfied based on determining that the reception signal intensities of the first antenna and the second antenna both have relatively low values. For example, the electronic device (101) can also determine whether the second switching condition set for periodic switching as in mathematical expression 4 is satisfied.

[0089] [Equation 4]

[0090] (2nd reception strength - 1st reception strength) < 2nd threshold reception strength

[0091] As in mathematical expression 4, the electronic device (101) can determine whether the second switching condition is satisfied by determining whether the first difference between the first reception intensity and the second reception intensity is less than the second threshold reception intensity. The electronic device (101) can also determine that the second switching condition is satisfied when the first reception intensity corresponding to the first antenna and the second reception intensity corresponding to the second antenna have a relatively small difference at substantially the same level even if the first switching condition is not satisfied.

[0092] In one embodiment, the electronic device (101) may maintain the configuration of the transmit antenna in operation 609 based on determining (operation 607 - No) that the at least one first parameter does not satisfy the second switching condition associated with the periodic switching of the transmit antenna. For example, the electronic device (101) may maintain the first antenna as the transmit antenna.

[0093] In one embodiment, the electronic device (101) may set a first scheduling ratio for a first switching period in operation 611 based on determining (operation 607 - Yes) that the at least one first parameter satisfies a second switching condition associated with periodic switching of the transmission antenna. In one embodiment, the first switching period may be at least a portion of a measurement time (for example, 100 seconds, but is not limited thereto). For example, if the measurement time is 100 seconds and the first switching period is set to one-tenth of the measurement time, the first switching period may be 10 seconds. The specific numerical value of the first switching period is not limited to the above-described example. In one embodiment, the electronic device (101) may change a SAR allocation corresponding to a band associated with a transmission signal. The SAR allocation may be set corresponding to a band. The SAR allocation may be set on the premise that one antenna does not perform switching and continuously radiates an RF signal during the measurement time. The electronic device (101) may change the set SAR allocation, considering that the SAR consumption may be relatively reduced by radiating RF signals only for at least a part of the measurement time when the first antenna or the second antenna performs periodic switching during the measurement time. The electronic device (101) may identify a band corresponding to a signal transmitted and received with a network (or, a base station, or a serving cell) with which a connection is established, and increase the set SAR allocation corresponding to the identified band. For example, the electronic device (101) may change the set SAR allocation for the first antenna corresponding to the first band associated with the transmission signal from a first value to a second value greater than the first value. The electronic device (101) may change the set SAR allocation for the second antenna corresponding to the first band associated with the transmission signal from a third value to a fourth value greater than the third value.The electronic device (101) can increase the time for operating at the maximum transmission power by increasing the SAR allocation. The electronic device (101) can determine the scheduling ratio that maximizes the time for operating at the maximum transmission power based on the changed SAR allocation. The electronic device (101) can set a first scheduling ratio based on the changed SAR allocation corresponding to the first antenna. The electronic device (101) can set a second scheduling ratio of the second antenna for the first switching cycle based on the changed SAR allocation corresponding to the second antenna.

[0094] In one embodiment, the electronic device (101) may transmit a signal associated with the first communication network based on the first switching period and the first scheduling ratio, in operation 613. For example, if the first switching period is 10 seconds and the first scheduling ratio is 70%, the electronic device (101) may transmit a signal associated with the first network communication through the first antenna for 7 seconds and transmit a signal associated with the first network communication through the second antenna for the remaining 3 seconds of the first switching period. The electronic device (101) may increase the SAR allocation (or Plimit) of the first antenna and the second antenna based on the reduction in SAR consumption due to the first antenna or the second antenna radiating the RF signal only for at least a portion of the measurement time. The electronic device (101) can relatively increase the time during which the antenna operates at its maximum transmission power by setting a scheduling ratio corresponding to the antenna based on the changed SAR allocation and periodically performing antenna switching according to the set scheduling ratio. In one embodiment, the periodic switching method based on the scheduling ratio may be referred to as a "second switching method."

[0095] FIG. 6b illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0096] According to one embodiment, the electronic device (101) (e.g., the communication processor (501)) may, in operation 621, check first parameter information and second parameter information. In one embodiment, the first parameter information may include a first RSRP (reference signal received power) corresponding to a signal received from a first communication network through a first antenna configured as a transmission antenna of the electronic device (101). The first parameter information may include a second RSRP corresponding to a signal received through a second antenna different from the first antenna. The first parameter information may include information related to the strength of the signal received through the first antenna. For example, the first parameter information may include RSRP, but this is exemplary and may also include SNR, RSRQ, or RSSI, without limitation. For example, the electronic device (101) may support changing the transmit antenna between the first antenna and the second antenna, and may assume that the first antenna is set as the transmit antenna while any one of operations 621, 623, 627, or 631 is performed. For example, based on the first antenna being the default transmit antenna, the electronic device (101) may set the first antenna as the transmit antenna. For example, the electronic device (101) may use the second antenna as the transmit antenna, and then set the first antenna as the transmit antenna based on satisfaction of a switching condition associated with the change of the transmit antenna, and there is no limitation on the manner or time at which the first antenna is set as the transmit antenna. In one embodiment, the second parameter information may include a first MTPL (maximum transmit power level) corresponding to the first antenna. The second parameter information may include a second MTPL corresponding to the second antenna.Here, the second parameter information may include, for example, MTPL, but the second parameter information may also include a smaller value among the MTPL and PcMax values, and there is no limitation.

[0097] In one embodiment, the electronic device (101) may, in operation 623, determine whether a first switching condition associated with a change of a transmission antenna is satisfied based on the first parameter information and the second parameter information. The electronic device (101) may also determine whether a first switching condition associated with a change of a transmission antenna is satisfied based on at least a portion of the first parameter information and the second parameter information. If the first switching condition set for changing the transmission antenna is not satisfied (623-No), the electronic device (101) may, in operation 627, determine whether a second switching condition associated with periodic switching of the transmission antenna is satisfied based on the first parameter information. If the condition set for changing the transmission antenna to the second antenna is satisfied (623-Yes), the electronic device (101) may, in operation 625, change the transmission antenna to the second antenna. The electronic device (101) may change the setting of the transmission antenna by changing the transmission antenna from the first antenna to the second antenna. For example, the electronic device (101) can determine whether the first switching condition set for changing the transmitting antenna as in mathematical expression 5 is satisfied.

[0098] [Equation 5]

[0099] (2nd RSRP - 1st RSRP) + (2nd MTPL - 1st MTPL) > 1st threshold

[0100] As in mathematical expression 5, the electronic device (101) can check whether the sum of the first difference between the first RSRP and the second RSRP and the second difference between the first MTPL and the second MTPL exceeds (or may be equal to or greater than) the first threshold value, thereby satisfying the condition set for changing the transmission antenna. The difference between RSRPs can be defined as, for example, a value obtained by subtracting the RSRP corresponding to the antenna set as the transmission antenna from the RSRP corresponding to the antenna not set as the transmission antenna, but there is no limitation thereto. The difference between MTPLs can be defined as, for example, a value obtained by subtracting the MTPL corresponding to the antenna set as the transmission antenna from the MTPL corresponding to the antenna not set as the transmission antenna, but there is no limitation thereto. In one embodiment, a method of checking whether antenna switching is performed based on at least one of the first parameter information and the second parameter information may be referred to as a "first antenna switching method." The first antenna switching method may be a method that considers the maximum value of the transmission power (or MTPL) associated with the SAR consumption, and may be a method that confirms the performance of antenna switching when the first difference between the first RSRP and the second RSRP is relatively large, and / or the SAR consumption of either the first antenna or the second antenna is relatively large.

[0101] In one embodiment, if the electronic device (101) determines that the first switching condition associated with the change of the transmission antenna is not satisfied based on at least some of the first parameter information and the second parameter information (operation 623 - No), then in operation 627, the electronic device (101) may determine whether the second switching condition associated with the periodic switching of the transmission antenna is satisfied based on at least some of the first parameter information. For example, the electronic device (101) may determine whether the second switching condition set for the periodic switching as in Equation 6 is satisfied.

[0102] [Equation 6]

[0103] (2nd RSRP) & (1st RSRP) < 1st critical RSRP

[0104] As in Equation 6, the electronic device (101) can determine whether the condition set for periodic switching of the transmitting antennas is satisfied by determining whether both the first RSRP and the second RSRP are less than (or may be less than) the first threshold RSRP. The electronic device (101) can determine whether the second switching condition is satisfied based on determining that both RSRPs corresponding to the first antenna and the second antenna have relatively low values. For example, the electronic device (101) can also determine whether the second switching condition set for periodic switching as in Equation 7 is satisfied.

[0105] [Equation 7]

[0106] (2nd RSRP - 1st RSRP) < 2nd critical RSRP

[0107] As in mathematical expression 7, the electronic device (101) can determine whether the second switching condition is satisfied by determining whether the first difference between the first RSRP and the second RSRP is less than the second threshold RSRP. Even if the first switching condition is not satisfied, the electronic device (101) can also determine that the second switching condition is satisfied when the first RSRP corresponding to the first antenna and the second RSRP corresponding to the second antenna have a relatively small difference at substantially the same level.

[0108] In one embodiment, the electronic device (101) may maintain the configuration of the transmit antenna in operation 631 based on determining that the first parameter information does not satisfy the second switching condition associated with the periodic switching of the transmit antenna (operation 627 - No). For example, the electronic device (101) may maintain the first antenna as the transmit antenna.

[0109] In one embodiment, the electronic device (101) may set a first scheduling ratio for a first switching period in operation 629 based on determining (operation 627 - Yes) that the first parameter information satisfies a second switching condition associated with periodic switching of the transmission antenna. In one embodiment, the first switching period may be at least a portion of a measurement time (for example, 100 seconds, but is not limited thereto). For example, if the measurement time is 100 seconds and the first switching period is set to one-tenth of the measurement time, the first switching period may be 10 seconds. The specific numerical value of the first switching period is not limited to the above-described example. In one embodiment, the electronic device (101) may change a SAR allocation corresponding to a band associated with a transmission signal. The SAR allocation may be set corresponding to a band. The SAR allocation may be set on the premise that one antenna does not perform switching during the measurement time and continuously radiates an RF signal. The electronic device (101) may change the set SAR allocation, considering that the SAR consumption may be relatively reduced by radiating RF signals only for at least a part of the measurement time when the first antenna or the second antenna performs periodic switching during the measurement time. The electronic device (101) may identify a band corresponding to a signal transmitted and received with a network (or, a base station, or a serving cell) with which a connection is established, and increase the set SAR allocation corresponding to the identified band. For example, the electronic device (101) may change the set SAR allocation for the first antenna corresponding to the first band associated with the transmission signal from a first value to a second value greater than the first value. The electronic device (101) may change the set SAR allocation for the second antenna corresponding to the first band associated with the transmission signal from a third value to a fourth value greater than the third value.The electronic device (101) can increase the time for operating at the maximum transmission power by increasing the SAR allocation. The electronic device (101) can determine the scheduling ratio that maximizes the time for operating at the maximum transmission power based on the changed SAR allocation. The electronic device (101) can set a first scheduling ratio based on the changed SAR allocation corresponding to the first antenna. The electronic device (101) can set a second scheduling ratio of the second antenna for the first switching cycle based on the changed SAR allocation corresponding to the second antenna.

[0110] In one embodiment, the electronic device (101) may perform periodic switching of the transmit antenna based on the scheduling ratio of the first antenna for the first switching period, in operation 629. The electronic device (101) may perform periodic switching of the transmit antenna, for example, between the first antenna and the second antenna. For example, if the first switching period is 10 seconds and the scheduling ratio of the first antenna is 70%, the electronic device (101) may transmit a signal associated with the first network communication through the first antenna for 7 seconds and transmit a signal associated with the first network communication through the second antenna for the remaining 3 seconds of the first switching period. The electronic device (101) may increase the SAR allocation (or Plimit) of the first antenna and the second antenna based on the reduction in SAR consumption due to the first antenna or the second antenna radiating RF signals only for at least a portion of the measurement time. The electronic device (101) can relatively increase the time during which the antenna operates at the maximum transmission power by setting a scheduling ratio corresponding to the antenna based on the changed SAR allocation and periodically performing antenna switching according to the set scheduling ratio. In one embodiment, the periodic switching method based on the scheduling ratio may be referred to as a "second switching method." The antenna used for the periodic switching is not limited to the above-described method. For example, those skilled in the art will readily understand that at least one antenna other than the first antenna or the second antenna among the plurality of antennas included in the electronic device (101) may be used for the periodic switching.

[0111] In one embodiment, the electronic device (101) may perform periodic switching of the transmission antenna when the band corresponding to the network communication is the B41 band. The MTPL (or Pmax) set corresponding to the B41 band may be, for example, 24 dBm. The average transmission power (or Plimit) for a predetermined period of time set based on the SAR allocation corresponding to the first antenna may be, for example, 21 dBm. The average transmission power (or Plimit) for a predetermined period of time set based on the SAR allocation corresponding to the second antenna may be, for example, 19 dBm. The average transmission power for a predetermined period of time set based on the SAR allocation may be a value set in consideration of the SAR margin based on a scheduling ratio of 100%. In one embodiment, the SAR consumption and the Plimit may have a relatively linear relationship. When a scheduling ratio of 100% is set, the first power corresponding to Plimit of 19 dBm can correspond to Equation 8.

[0112] [Equation 8]

[0113] ((19 / 10)^10)*10^-3 = 1st power

[0114] In one embodiment, the electronic device (101) may set the scheduling ratio of the first antenna and / or the second antenna when it determines that the second switching condition is satisfied. The electronic device (101) may set a Plimit value corresponding to the scheduling ratio, for example, according to Equation 9.

[0115] [Equation 9]

[0116] (Plimit corresponding to scheduling ratio) = (1st power * 100) / (scheduling ratio)

[0117] In one embodiment, the sum of the scheduling ratio corresponding to the first antenna and the scheduling ratio corresponding to the second antenna may be 100%. In one embodiment, when outputting a signal of maximum power, the average output power corresponding to the scheduling ratio may correspond to Equation 10.

[0118] [Equation 10]

[0119] (Average output power corresponding to scheduling ratio) = Pmax * (scheduling ratio)

[0120] In one embodiment, the electronic device (101) can relatively increase the time interval for outputting the maximum transmission power by setting a Plimit value higher than the Plimit value set assuming a scheduling ratio of 100%, based on setting a scheduling ratio that complies with the total SAR consumption according to the standard.

[0121] In one embodiment, the electronic device (101) may identify an event associated with a handover to the B3 band while performing a call service based on the B41 band. The electronic device (101) may identify an event associated with a handover to the B3 band while performing a call service based on the B41 band for, for example, 50 seconds. Considering that the SAR consumption may be different due to a different output power corresponding to a band associated with network communication, the electronic device (101) may change the scheduling ratio of the first antenna corresponding to the changed band. The electronic device (101) may identify the SAR value consumed corresponding to the B41 band for 50 seconds. The electronic device (101) may change the SAR allocation (or Plimit) of the first antenna based on the SAR margin (or SAR room) for the remaining 50 seconds of the 100-second reference time. The electronic device (101) can change the scheduling ratio of the first antenna for the first switching cycle based on the changed SAR allocation of the first antenna.

[0122] Fig. 7a is a drawing for explaining a change in a transmission antenna according to a comparative example. Fig. 7b is a drawing for explaining a change in a transmission antenna according to one embodiment.

[0123] For example, in the example of FIG. 7A, the electronic device (101) can perform an antenna switching operation between the first antenna and the second antenna based on the maximum value of the reception strength and the transmission power. In the example of FIG. 7A, it is assumed that the first band is the N77 band, Pmax is 22.5 dBm, Plimit corresponding to the first antenna is 18 dBm, and Plimit corresponding to the second antenna is 15 dBm. Referring to the example of FIG. 7A, when Plimit (or SAR allocation) is fixed, the electronic device (101) can output an RF signal corresponding to the maximum value (701) of the transmission power for the first antenna at the beginning of the measurement time, but performs a backoff (713) due to the accumulation of SAR consumption, and outputs an RF signal corresponding to the backed-off transmission power (711). The backoff of the transmission power can cause a swing (710) of the output power. Referring to the example of FIG. 7a, when Plimit (or SAR allocation) is fixed, the electronic device (101) can output an RF signal corresponding to the maximum value (701) of the transmission power for the second antenna at the beginning of the measurement time, but as SAR consumption accumulates, a backoff is performed (723) and an RF signal corresponding to the backed-off transmission power (721) is output. The backoff of the transmission power can cause a swing (720) of the transmission power.

[0124] In one embodiment, referring to FIG. 7B, the electronic device (101) may perform antenna switching periodically based on a switching period and a scheduling ratio. The electronic device (101) may change the SAR allocation (or Plimit) during the measurement time for the first antenna and the second antenna, at least as part of the operation of setting the scheduling ratio. For example, the electronic device (101) may set the first scheduling ratio to 59% or the second scheduling ratio to 41% when the first band is the N77 band. The electronic device (101) may change the Plimit of the first antenna from 18 dBm to 20.29 dBm, at least as part of the operation of setting the scheduling ratio. The electronic device (101) may change the Plimit of the first antenna from 15 dBm to 18.87 dBm, at least as part of the operation of setting the scheduling ratio. Referring to FIG. 7B, the electronic device (101) can continuously transmit an RF signal corresponding to a maximum value (701) of transmission power for a measurement time (e.g., 100 seconds) through the first antenna or the second antenna based on a periodic switching method. The average output power corresponding to the first antenna (e.g., 19.59 dBm, but without limitation) and the average output power corresponding to the second antenna (e.g., 18.66 dBm, but without limitation) can relatively increase compared to the case where Plimit is fixed.

[0125] FIG. 8 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0126] According to one embodiment, the electronic device (101) (e.g., the communication processor (501)) may, in operation 801, determine at least one first parameter. For example, the electronic device (101) may determine a first reception intensity corresponding to a first antenna and a second reception intensity corresponding to a second antenna.

[0127] In one embodiment, the electronic device (101) may, in operation 803, determine whether at least one first parameter satisfies the second switching condition. With respect to operation 803, descriptions overlapping with those of FIG. 6 may not be repeated. Based on determining that at least one first parameter does not satisfy the second switching condition (operation 803 - NO), the electronic device (101) may, in operation 811, set the first antenna as a transmitting antenna.

[0128] In one embodiment, the electronic device (101) may set a first scheduling ratio for the first switching cycle in operation 805 based on confirmation that at least one first parameter satisfies the second switching condition (operation 803 - Yes). With respect to operation 805, descriptions overlapping with those of FIG. 6 may not be repeated.

[0129] In one embodiment, the electronic device (101) may transmit a signal associated with the first communication network based on the first switching cycle and the first scheduling ratio. Regarding operation 807, any description overlapping with that of FIG. 6 may not be repeated.

[0130] In one embodiment, the electronic device (101) may, based on the first switching cycle and the first scheduling ratio, determine an event associated with a handover in operation 809 while transmitting a signal associated with the first communication network. For example, the electronic device (101) may determine a change in a band corresponding to a signal transmitted and received with the network (or a base station). The electronic device (101) may determine an event associated with a handover to a second band different from the first band. In one embodiment, the electronic device (101) may perform operations 801 and 803 based on determining an event associated with the handover. By performing operations 801 and 803 based on determining an event associated with the handover, the electronic device (101) may determine whether an electric field corresponding to the electronic device (101) is degraded to a degree that requires periodic switching. The electronic device (101) may maintain the periodic switching operation based on the determination that at least one first parameter still satisfies the second switching condition (Operation 803 - Yes). For example, the electronic device (101) may change the first scheduling ratio based on the determination of the second band. The electronic device (101) may transmit a signal associated with the first communication network through the first antenna or the second antenna based on the first switching period and the changed first scheduling ratio.

[0131] In one embodiment, the electronic device (101) may set the first antenna as a transmission antenna in operation 811 based on determining that the at least one first parameter does not satisfy the second switching condition (operation 803 - No). For example, the first antenna may be an antenna having a higher reception strength compared to the second antenna. The electronic device (101) may change the antenna switching method to the first switching method based on determining that the reception channel status of the first antenna or the second antenna is relatively good. For example, the electronic device (101) may determine whether the at least one first parameter and the at least one second parameter satisfy the condition set for changing the transmission antenna based on determining that the first reception strength or the second reception strength is greater than or equal to a first threshold reception strength.

[0132] In one embodiment, the electronic device (101) may, in operation 813, verify at least one second parameter. With respect to operation 813, descriptions overlapping with those of FIG. 6 may not be repeated.

[0133] In one embodiment, the electronic device (101) may, in operation 815, determine whether at least one first parameter and at least one second parameter satisfy a first switching condition. Based on determining that at least one first parameter and at least one second parameter satisfy the first switching condition (operation 815 - Yes), the electronic device (101) may change the transmitting antenna to the second antenna. Based on determining that at least one first parameter and at least one second parameter do not satisfy the first switching condition (operation 815 - No), the electronic device (101) may maintain the transmitting antenna as the first antenna.

[0134] In one embodiment, the electronic device (101) may set the second antenna as a transmitting antenna based on determining that the first reception strength is less than the third threshold reception strength. For example, the electronic device (101) may set the second antenna as a transmitting antenna based on determining that a signal cannot be successfully received by the first antenna even when performing periodic switching.

[0135] FIG. 9 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0136] According to one embodiment, the electronic device (101) (e.g., the communication processor (501)) may, in operation 901, transmit a signal associated with a first communication network based on a first antenna switching scheme.

[0137] In one embodiment, the electronic device (101) may, in operation 903, determine whether at least one first parameter satisfies the second switching condition. The electronic device (101) may maintain the first antenna switching mode based on determining that at least one first parameter does not satisfy the second switching condition (operation 903 - No).

[0138] In one embodiment, the electronic device (101) may, in operation 905, transmit a signal associated with the first communication network based on the second antenna switching scheme, based on determining (operation 903 - Yes) that at least one first parameter satisfies the second switching condition.
