Description

A method for performing non-terrestrial network communication, an electronic device supporting the same, and a storage medium

[0001] Embodiments of the present disclosure relate to a method for performing non-terrestrial network communication, an electronic device supporting the same, and a storage medium.

[0002] Electronic devices supporting non-terrestrial network communication (e.g., satellite communication) are being actively introduced. As an example, electronic devices can communicate with a satellite of an existing satellite communication provider by utilizing that provider's frequencies and communication methods. As another example, electronic devices can communicate with a satellite using cellular frequencies based on the LTE (long-term evolution) standard (or 5G standard). As yet another example, electronic devices can communicate with a satellite based on the 5G NTN (non-terrestrial networks) standard.

[0003] For example, if an electronic device communicates with a non-terrestrial network based on LTE standards, some of the frequencies defined in LTE standards may be allocated for non-terrestrial communication. The electronic device may perform satellite communication using the protocol stack used for terrestrial communication, and an additional protocol stack for non-terrestrial communication may not be required.

[0004] In order to transmit a signal from an electronic device to a communication network (e.g., a base station), data generated from a processor or communication processor within the electronic device may be processed through RFIC (radio frequency integrated circuit) and RFFE (radio frequency front end) circuits and then transmitted to the outside of the electronic device through at least one antenna. The electronic device may include at least one antenna to transmit signals of various frequency bands.

[0005] User equipment (UE) can transmit electromagnetic waves for data transmission and reception with base stations. Electromagnetic waves radiated by user devices can have harmful effects on the human body, and various domestic and international organizations are attempting to limit electromagnetic waves that cause such harmful effects. For example, Specific Absorption Rate (SAR) is a numerical value indicating how much electromagnetic wave radiated from a mobile communication terminal is absorbed by the human body. SAR uses the unit KW / g (or mW / g), which can represent the amount of power (KW, W, or mW) absorbed per gram of the human body. As the issue of electromagnetic waves being harmful to the human body has emerged, SAR limiting standards for mobile communication terminals have been established.

[0006] The information described above may be provided as related art for the purpose of aiding understanding of this document. None of the foregoing is to be claimed as prior art related to this document, nor is it to be used to determine prior art.

[0007] According to one embodiment of the present disclosure, an electronic device may include a plurality of antennas, a power amplifier, a switch configured to selectively connect the power amplifier to an NTN antenna of a first antenna group or an NTN antenna of a second antenna group among the plurality of antennas, at least one processor including a processing circuit, and a memory for storing instructions. When the instructions are executed individually or collectively by the at least one processor, the electronic device may cause the electronic device to identify an event for transmitting a signal associated with NTN communication. When the instructions are executed individually or collectively by the at least one processor, the electronic device may cause the electronic device to identify whether time-average SAR (TAS) information associated with cellular network communication corresponding to the first antenna group satisfies a condition set for the TAS function based on identifying the event for transmitting a signal associated with NTN communication. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may cause the device to transmit a signal associated with the NTN communication through the NTN antenna of the first antenna group by controlling the switch based on confirming that the TAS information associated with the cellular network communication corresponding to the first antenna group satisfies the conditions set for the TAS function. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may cause the device to transmit a signal associated with the NTN communication through the NTN antenna of the second antenna group by controlling the switch based on confirming that the TAS information associated with the cellular network communication corresponding to the first antenna group does not satisfy the conditions set for the TAS function.The distance between the NTN antenna of the second antenna group and at least one cellular antenna of the first antenna group may be greater than the critical distance based on the specific absorption rate (SAR).

[0008] According to one embodiment of the present disclosure, the method may include an operation of checking an event for transmitting a signal associated with NTN communication. The method may include a method of checking whether TAS information associated with cellular network communication corresponding to a first antenna group satisfies a condition set for a TAS function, based on checking an event for transmitting a signal associated with NTN communication. The method may include an operation of transmitting a signal associated with NTN communication through the NTN antenna of the first antenna group by controlling a switch set to selectively connect a power amplifier of an electronic device to the NTN antenna of the first antenna group or the NTN antenna of the second antenna group among a plurality of antennas of the electronic device, based on checking that the TAS information associated with cellular network communication corresponding to the first antenna group satisfies the condition set for the TAS function. The method may include an operation of transmitting a signal associated with NTN communication through the NTN antenna of the second antenna group by controlling the switch based on checking that the TAS information associated with cellular network communication corresponding to the first antenna group does not satisfy the condition set for the TAS function. The distance between the NTN antenna of the second antenna group and at least one cellular antenna of the first antenna group may be greater than the threshold distance based on SAR.

[0009] According to one embodiment of the present disclosure, a storage medium for storing computer-readable instructions may be provided. When the instructions are executed individually or collectively by at least one processor of an electronic device, the electronic device may cause the electronic device to check for an event to transmit a signal associated with NTN communication. When the instructions are executed individually or collectively by the at least one processor, the electronic device may cause the electronic device to check whether TAS information associated with cellular network communication corresponding to a first antenna group satisfies a condition set for a TAS function based on checking for an event to transmit a signal associated with NTN communication. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may be caused to transmit a signal associated with the NTN communication through the NTN antenna of the first antenna group by controlling a switch configured to selectively connect the power amplifier of the electronic device to the NTN antenna of the first antenna group or the NTN antenna of the second antenna group among the plurality of antennas of the electronic device, based on confirming that the TAS information associated with the cellular network communication corresponding to the first antenna group satisfies the conditions set for the TAS function. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may be caused to transmit a signal associated with the NTN communication through the NTN antenna of the second antenna group by controlling the switch based on confirming that the TAS information associated with the cellular network communication corresponding to the first antenna group does not satisfy the conditions set for the TAS function.The distance between the NTN antenna of the second antenna group and at least one cellular antenna of the first antenna group may be greater than the threshold distance based on SAR.

[0051] FIG. 2a is a block diagram (200) of an electronic device (101) for supporting legacy network communication and 5G network communication according to one embodiment. Referring to FIG. 2a, the electronic device (101) may include a first communication processor (212), a second communication processor (214), a first radio frequency integrated circuit (RFIC) (222), a second RFIC (224), a third RFIC (226), a fourth RFIC (228), a first radio frequency front end (RFFE) (232), a second RFFE (234), a first antenna module (242), a second antenna module (244), a third antenna module (246), and antennas (248). The electronic device (101) may further include a processor (120) and a memory (130). The second network (199) may include a first cellular network (292) and a second cellular network (294). According to another embodiment, the electronic device (101) may further include at least one of the components described in FIG. 1, and the second network (199) may further include at least one other network. According to one embodiment, the first communication processor (212), the second communication processor (214), the first RFIC (222), the second RFIC (224), the fourth RFIC (228), the first RFFE (232), and the second RFFE (234) may form at least a part of the wireless communication module (192). According to another embodiment, the fourth RFIC (228) may be omitted or included as part of the third RFIC (226).

[0052] The first communication processor (212) can establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and support legacy network communication through the established communication channel. According to one embodiment, the first cellular network may be a legacy network including a 2nd generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor (214) can 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 support 5G network communication through the established communication channel. According to one embodiment, the second cellular network (294) may be a 5G network defined by the 3GPP (3rd generation partnership project). Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support the establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or lower) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0053] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted through the second cellular network (294) can be changed to be transmitted through the first cellular network (292). In this case, the first communication processor (212) can receive transmitted 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) through the inter-processor interface (213). The above inter-processor interface (213) may be implemented, for example, as a UART (universal asynchronous receiver / transmitter) interface (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express), but there is no limitation on the type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information, for example, using shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output strength, and RB (resource block) allocation information, to and from the second communication processor (214).

[0054] 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 to and from the second communication processor (214) through a processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data to and from the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no restriction on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) (e.g., application processor) using shared memory.

[0055] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented within a single chip or a single package. According to one embodiment, the first communication processor (212) or the second communication processor (214) may be formed within a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190). For example, as shown in FIG. 2b, the integrated communication processor (260) may support functions for communication with both the first cellular network (292) and the second cellular network (294).

[0056] 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) for storing instructions that cause the execution of at least some of the operations performed according to various embodiments, and a processing circuit (or, not limited to its name, such as an operation circuit) for executing the instructions. The instructions stored in the memory may cause the electronic device (101) to perform at least one operation when executed individually or collectively by at least one processor.

[0057] The first RFIC (222) can convert a baseband signal generated by the first communication processor (212) during transmission into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network (292) (e.g., legacy network). During reception, the RF signal is acquired from the first network (292) (e.g., legacy network) through an antenna (e.g., first antenna module (242)) and can be preprocessed through an RFFE (e.g., first RFFE (232)). The first RFIC (222) can convert the preprocessed RF signal into a baseband signal so that it can be processed by the first communication processor (212).

[0058] The second RFIC (224) can convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal of the Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., 5G network) (hereinafter, 5G Sub6 RF signal). When receiving, the 5G Sub6 RF signal is acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., the second antenna module (244)) and can be preprocessed through an RFFE (e.g., the second RFFE (234)). The second RFIC (224) can convert the preprocessed 5G Sub6 RF signal into a baseband signal so that it can be processed by the corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0059] The third RFIC (226) can convert a baseband signal generated by the second communication processor (214) into an RF signal of the 5G Above6 band (e.g., approximately 6 GHz to approximately 60 GHz) to be used in the second cellular network (294) (e.g., 5G network) (hereinafter, 5G Above6 RF signal). Upon reception, the 5G Above6 RF signal may 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) may be formed as part of the third RFIC (226).

[0060] According to one embodiment, the electronic device (101) may include a fourth RFIC (228) separately from or at least as part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter referred to as an IF signal) in an intermediate frequency band (e.g., 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) through 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.

[0061] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as at least part of a single chip or a single package. According to one embodiment, if 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 either the first RFFE (232) or the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least part of a single chip or a single package. According to one embodiment, at least one of the first antenna module (242) or the second antenna module (244) may be omitted or combined with another antenna module to process RF signals of a plurality of corresponding bands.

[0062] According to one embodiment, the third RFIC (226) and the antenna (248) may be placed on the same substrate to form a third antenna module (246). For example, a wireless communication module (192) or a processor (120) may be placed on the first substrate (e.g., main PCB). In this case, the third RFIC (226) may be placed on a portion of a second substrate (e.g., sub PCB) separate from the first substrate (e.g., bottom surface), and the antenna (248) may be placed on another portion of a second substrate (e.g., top surface) to form the third antenna module (246). By placing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line between them. This can, for example, reduce the loss (e.g., attenuation) of signals in the high-frequency band (e.g., about 6 GHz to about 60 GHz) used for 5G network communication by the transmission line. As a result, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0063] According to one embodiment, the antenna (248) may be formed as an antenna array comprising a plurality of antenna elements that can 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). During transmission, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device (101) (e.g., a base station of a 5G network) through the corresponding antenna element. During reception, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal received from the outside through the corresponding antenna element to the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device (101) and the outside.

[0064] The second cellular network (294) (e.g., 5G network) may be operated independently of the first cellular network (292) (e.g., legacy network) (e.g., Stand-Alone (SA)) or connected (e.g., Non-Stand Alone (NSA)). For example, the 5G network may only have an access network (e.g., 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) 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., evolved packed core (EPC)). 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) is stored in memory (230) and can be accessed by other parts (e.g., processor (120), first communication processor (212), or second communication processor (214)).

[0065] FIG. 3a illustrates a flowchart for explaining the operation method of an electronic device according to various embodiments. The embodiment of FIG. 3a is to be explained with reference to FIG. 3b and FIG. 4a through 4e. FIG. 3b is a diagram for explaining transmission power and SAR over time according to various embodiments. FIG. 4a through 4c illustrate graphs of transmission power over time according to various embodiments. FIG. 4d through 4e illustrate tables of transmission power over time according to various embodiments.

[0066] According to one embodiment, an electronic device (101) (e.g., the electronic device (101) of FIG. 1, FIG. 2a, or FIG. 2b) may back off the transmission power, the maximum transmission power level (MTPL), when it is expected that the SAR expected by the transmission power will exceed a threshold value, for example. For example, when the occurrence of a specific event (e.g., grip, hot-spot, or proxy) is confirmed, the electronic device (101) may transmit an RF signal with a backoff power corresponding to the event, or transmit an RF signal with a transmission power set based on the backoff maximum transmission power level. The backoff operation may include lowering the transmission power to a certain level to reduce the amount of electromagnetic waves emitted that may affect the human body.

[0067] According to one embodiment, a technique for back-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 SARs generated over a certain period of time) may be used. SARs that instantaneously affect the human body and / or SARs that affect the human body on average must also be considered, and accordingly, back-off of the transmission power (or maximum transmission power level) may be performed when the total amount of accumulated SAR values ​​(or the average value of SARs generated over a certain period of time) satisfies a specified condition.

[0068] According to one embodiment, the electronic device (101) may perform a power control operation to back off the transmission power based on the total amount of accumulated SAR values. According to one embodiment, the "SAR back-off operation" may include an operation to lower the transmission power of the antenna of the electronic device (101) (e.g., antenna module (197) of FIG. 1) to a certain level. When controlling SAR based on accumulated SAR values, the electronic device (101) can control the transmission power based on the average value over a certain period of time so that the accumulated SAR value during a time interval corresponding to a time window does not exceed the SAR threshold without performing frequent back-offs. When the electronic device (101) controls the transmission power based on the average value of SAR generated over a certain period of time, compared to a power control method that performs back-off by comparing the instantaneously generated SAR value (or instantaneous value) with the SAR threshold, the risk of transmission performance degradation due to frequent back-offs can be relatively reduced.

[0069] In one embodiment, the total amount of accumulated SAR for each of the plurality of antennas can be managed, and accordingly, the maximum transmission power level for each of the plurality of antennas can be set.

[0070] According to one embodiment, an electronic device (101) (e.g., at least one of a processor (120), a first communication processor (212), a second communication processor (214), or an integrated communication processor (260)) may call (or read) a plurality of tables for transmission power corresponding to a plurality of times in operation 301. Before describing the embodiment associated with FIG. 3a, terms such as those in Table 1 are defined.

[0071] a. Normal MAX Power: The maximum transmit power when there is remaining SAR margin. b. Normal Max SAR: The SAR value generated when operating at Normal MAX Power. c. Backoff MAX Power: The maximum transmit power when performing backoff due to insufficient SAR margin. d. Backoff Max SAR: The SAR value generated when operating at Backoff Max Power. e. Measurement Time (T): The period for calculating cumulative SAR or the average of SAR. f. Measurement Period (P): The cycle (or time interval) for calculating SAR. g. Number of tables for SAR calculation: T / P - 1h. i. Average SAR LIMIT: The maximum average SAR value that must not be exceeded during T. j. Average Time (A_Time): The time taken to measure cumulative SAR. j. Cumulative SAR: The sum of SAR accumulated during Average Time. k. Max Cumulative SAR: Average SAR LIMIT X Measurement Time. l. Average SAR: The average SAR value used during Average Time. m. Tx Room : Max Cumulative SAR - Cumulative SAR, remaining SARn. Remaining Time(R_Time) : Total measurement time - Time to measure SAR so far(A_Time)

[0072] First, refer to FIGS. 4a through 4c for an explanation of the table. Referring first to FIG. 4a, a graph including transmission power for multiple time points (401 to 449) is shown. The cumulative SAR (cumulative SAR in Table 1) during the measurement time (Measurement time in Table 1), for example, including 50 time points, may be maintained at a value less than or equal to the maximum cumulative SAR (Max cumulative SAR in Table 1). The electronic device (101) may determine the transmission power of the RF signal to be transmitted at the current time point (449) such that, for example, the cumulative SAR at the current time point (449) and any past time points (409 to 448) (e.g., Average Time in Table 1), in addition to the cumulative SAR at nine future time points (not shown) (e.g., Remain Time in Table 1), remains less than or equal to the maximum cumulative SAR. Additionally, the electronic device (101) can identify transmission powers (452) that are shifted by 1 time point from the transmission powers (451) at the current time point (449) of FIG. 4a and at any past time points (409 to 448), as in FIG. 4b. The meaning of being shifted by 1 time point may be that the data of the earliest time point (e.g., time point 409 in FIG. 4a) is not reflected. The number of transmission powers (452) at the current time point (449) and at any past time points (410 to 448) is 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 time point (449) such that the sum of the SAR by the transmission powers (452) and the predicted SAR at an additional 10 future time points remains below the maximum accumulated SAR. As shown in FIG. 4c, the electronic device (101) can identify the transmission powers (453) at the current time point (449), which is shifted by 25 times from the transmission powers (451), and at any past time points (434 to 448).The number of transmission powers (453) is 16, which is 25 fewer than the number of transmission powers (451) in FIG. 4a, which is 41. The electronic device (101) can determine the transmission power at the current time point (449) such that the sum of the SAR by the transmission powers (453) and the predicted SAR at an additional 34 future time points remains below the maximum cumulative SAR. Although not illustrated, the electronic device (101) can manage multiple graphs shifted by one time point. The period for calculating the SAR is the measurement period (P) of Table 1, which may be, for example, the interval between the transmission powers in FIG. 4a through 4c. The electronic device (101) can calculate and / or manage T / P - 1 tables for a specific time point. Below, with reference to FIG. 4d and 4e, a configuration for verifying the SAR prediction value will be described.

[0073] Referring to FIG. 4d, the electronic device (101) can check the k-th SAR table (460). The k-th SAR table (460) may include D1, which is the cumulative SAR value (461) at least one past time point, the maximum SAR value (462) (D2) at the current time point, and the expected SAR value (463) (D3) at least one future time point. Referring to the graph, the cumulative SAR value corresponding to at least one past time point (461) may be D1. D1, which is the cumulative SAR value (461) at at least one past time point, may be determined based on the antenna settings. 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. N, which is the total number of time points (e.g., 100), 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 smaller than the total number of time points. The electronic device (101) can check D1, which is the cumulative SAR value of Nk past time points (471). The electronic device (101) can use the maximum SAR value (S1) for the current time point (472). The maximum SAR value (S1) (e.g., normal max SAR in Table 1) may 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, for the current time point (472), the SAR value immediately preceding the current time point (472) may be used. In one embodiment, for the current time point (472), the average SAR value of the past time points (471) of the current time point (472) may be used. The electronic device (101) can be calculated as the sum of SAR values ​​(S2) (e.g., backoff max SAR of Table 1) for backoff transmission power (e.g., backoff max power of Table 1) for at least one future point in time (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 D1+D2+D3, the sum of the SARs for N time points consisting of Nk past time points, 1 current time point, and k-1 future time points, exceeds the maximum cumulative SAR. If it is confirmed that it exceeds, the electronic device (101) can back off the transmission power of the current time point. Referring to FIG. 4e, the electronic device (101) can also check the k+1-th table (480) as in FIG. 4e. The electronic device (101) can check in the k+1th table (480) that the cumulative SAR value (481) of at least one past time point is D4, the maximum SAR value (482) of the current time point is D2, and the expected SAR value (483) of at least one future time point is D5. The electronic device (101) can check whether the cumulative SAR value of D4 + D2 + D5 exceeds the maximum cumulative SAR. In the k+1th 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 kth table. In the k+1th 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 kth table.

[0074] According to one embodiment, in operation 303, the electronic device (101) can check the past SAR cumulative value, the current time point, and the SAR predicted value at a future time point for a plurality of tables corresponding to at least one future time point. The electronic device (101) can check the SAR cumulative value for a first table and a total of N-1 tables shifted from the first table by time point i (i is greater than or equal to 1 and less than N-2). In operation 305, the electronic device (101) can check whether there exists a table where the sum of the SAR cumulative value and the SAR predicted value exceeds a threshold. If there exists a table where the threshold exceeds (305-Yes), in operation 307, the electronic device (101) can back off any one of the transmission powers of at least some of the RF signals (or at least some of the MTPL (maximum transmission power limit)). Those skilled in the art will understand that back-off of transmission power in this document may be replaced by 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 with a set transmission power in operation 309. In one embodiment of the present disclosure, backoff of the maximum transmission power may mean backoff of the maximum transmission power.

[0075] As described above, the electronic device (101) can determine the maximum value of the transmission power such 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 such that the cumulative SAR during the measurement time does not exceed the Max cumulative SAR. The electronic device (101) can determine the maximum value of the maximum power for the next time interval every P time. For example, the conditions for operating at normal max power during the next P time may be as follows.

[0076] Condition: Tx Room > SAR generated during operation at normal max power during the next P (normal max SAR in Table 1) + SAR generated during operation at backoff max power during (Remaining Time - P) (backoff max SAR in Table 1) = PX normal max SAR + (Remaining Time - P) X backoff max SAR

[0077] The Tx Room in the condition may be the 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 a future point in time as described, for example, in FIG. 4a to 4e. P may represent the current point in time. Average time may represent a past point in time. The condition being satisfied may mean that even if the electronic device (101) sets the maximum transmission power of normal max power during time P, there is no table where the accumulated SAR exceeds the Max accumulated SAR. The condition not being satisfied may mean that if the electronic device (101) sets the maximum transmission power of normal max power during time P, there is a possibility that there is a table where the accumulated SAR exceeds the Max accumulated SAR, and in this case, the electronic device (101) may set the backoff max power as the maximum transmission power during time P.

[0078] Table 2 is an example of variables and conditions.

[0079] [Example of Variable Settings] i. Normal MAX Power: 23 dBm i. Backoff MAX Power: 20 dBm iii. Measurement Time (T): 100 sec iv. Measurement Period (P): 0.5 sec v. Number of SAR Calculator Tables: 199 vi. Average SAR LIMIT: 1.5 mW / g vi. Max Cumulative SAR: 150 mW / g viii. SAR when Normal Max SAR => 23 dBm: 2 mW / gx. When Backoff Max SAR is 20dBm, SAR: 1mW / g [the point at which maximum power transitions from normal max power to backoff max power] Average time X normal max power + (100 - average time) X backoff max power <= Point at which cumulative max SAR is satisfied = Average time X 2 mW / g + (100 - average time) X 1mW / g <= 150 mW / g <=> Average time <= 50

[0080] In the example in Table 2, it is explained that continuous use of normal max power is possible with maximum transmission power for 50 seconds, and that backoff to backoff max power is required after 50 seconds. For example, let us assume that an RF signal is transmitted at normal max power of 23 dBm for 50 seconds, an RF signal is transmitted at normal max power of 23 dBm for the next P (0.5 seconds), and an RF signal is transmitted at backoff max power of 20 dBm for 49.5 seconds (Remain time - P). In this case, the Tx Room can be 50 mW / g, calculated as 150 mW / g - 50 x 2 mW / g. The SAR generation during time P can be 1 mW / g, calculated as 2 mW / g x 0.5 seconds. The SAR generation during (Remain time - P) can be 49.5 mW / g, calculated as 49.5 seconds x 1 mW / g. At this time, the cumulative SAR during P and (Remain time - P) exceeds the Tx room at 50.5 mW / g, which confirms that backoff of the maximum transmission power at time P is required. The above example will be explained with reference to FIG. 3b, which describes the transmission power associated with a radio access technology (RAT). For example, referring to FIG. 3b, it can be seen that the maximum transmission power can be set to normal max power (351) up to A seconds (e.g., 50 seconds), but is backoff to backoff max power (352) after A seconds. Depending on the backoff of the maximum transmission power, the slope of the second part (362) of the cumulative SAR can be formed to be smaller than the slope of the first part (361) of the cumulative SAR.It can be confirmed that the average SAR (331) before A second exceeds the average SAR limit (340), but at the point when it becomes 100 seconds due to backoff, the average SAR (332) is equal to the value of the average SAR limit (340). FIG. 5 is a diagram for explaining the connection of an electronic device according to one embodiment.

[0081] According to one embodiment, the electronic device (101) may be located within the coverage (522) of the satellite (521). Meanwhile, those skilled in the art will understand that the satellite (521) in this disclosure may be replaced with another type of electronic device that supports non-ground communication. The electronic device (101) may connect (523) to the satellite (521) within the coverage (522) of the satellite (521). For example, the electronic device (101) may perform a cell scan within the coverage (522) of the satellite (521). As a result of performing the cell scan, the electronic device (101) may identify the satellite (521) (or may be named a cell corresponding to the satellite (521)). If the satellite (521) satisfies the cell selection conditions, the electronic device (101) may camp on the satellite (521). In one embodiment, the camp-on operation may include an operation to check system information ("SI") and / or paging for a cell (or satellite) selected by the electronic device (101). The electronic device (101) may camp on the satellite (521) and perform at least one operation to establish a connection (e.g., a radio resource control (RRC) connection) with the satellite (521). Based on the established connection, the electronic device (101) may perform at least one operation to attach (or register) to a core network corresponding to the satellite (521) (e.g., a mobility management entity (MME) or an access and mobility management function (AMF)). The connection (523) to the satellite (521) may include, for example, camp-on, establishing a connection, and / or attaching, but is not limited to. The coverage (522) of the satellite communication may be relatively larger than the coverage (502, 512) provided by ground base stations (501, 511) (e.g., may be about 50 times larger).The electronic device (101) can connect to the ground base station (501) (or ground communication network) when the location of the electronic device (101) moves (532) into the coverage (502) provided by the ground base station (501). The electronic device (101) may also move (531) outside the coverage (502) provided by the ground base station (501). The satellite communication-based coverage (522) can cover, for example, an area (524) that is not covered by the ground communication coverage (502, 512), and accordingly, the user can perform communication using the electronic device (101) even in an area where ground communication is not supported.

[0082] For example, satellite communication based on a satellite (521) may support limited frequency resources and / or limited services. Satellite communication may not support other general data transmission and reception services (e.g., video streaming, but without limitation) while providing limited services such as emergency services (e.g., emergency calls) and / or SMS (short message service). In one embodiment, satellite communication may support a limited bandwidth (e.g., about 1.4 MHz) compared to terrestrial communication. For example, even when satellite communication supports voice calls and / or data services, the total cell capacity may be relatively low, about 2 to 4 Mbps. On the other hand, terrestrial communication supports a bandwidth of up to 100 MHz, for example when carrier aggregation (CA) is enabled, and the cell capacity may also exceed 1 Gbps.

[0083] FIG. 6 is a block diagram illustrating an exemplary electronic device according to one embodiment. The embodiment of FIG. 6 is to be described with reference to FIG. 7a, FIG. 7b, FIG. 7c, and FIG. 8. FIG. 7a, FIG. 7b, and FIG. 7c are illustrative diagrams illustrating a plurality of antennas of an electronic device according to one embodiment. FIG. 8 is an illustrative diagram illustrating the transmission of a signal associated with NTN communication and the transmission of a signal associated with cellular network communication of an electronic device according to one embodiment.

[0084] Referring to FIG. 6, in one embodiment, the electronic device (101) may include a communication processor (610), an RFIC (620), a first RFFE (630), a second RFFE (640), a first NTN transmitting antenna (651), a second NTN transmitting antenna (653), and a third NTN transmitting antenna (661). In the present disclosure, the NTN antennas (651, 653, 661) are referred to as "NTN transmitting antennas" to describe the transmitting operation by the NTN antennas, but are not limited thereto. For example, the first NTN transmitting antenna (651) may operate as a primary receiving antenna ("PRX") that receives an RF signal of a first band (e.g., B255). The second NTN transmitting antenna (653) may operate as a primary receiving antenna that receives an RF signal of a second band (e.g., B256). The third NTN transmitting antenna (661) may operate as a diversity receiving antenna (diversity Rx antenna) that receives RF signals of the first band or the second band. In FIG. 6, for convenience of explanation, only the NTN antennas (651, 653, 661) and RFFEs (630, 640) connected to the NTN antennas are shown, and the electronic device (101) may further include cellular antennas (e.g., antenna module (197), first antenna module (242), second antenna module (244), third antenna module (246), and / or antennas (248)) that transmit and / or receive signals for cellular network communication and RFFEs (e.g., first RFFE (232), second RFFE (234), and / or third RFFE (236)) connected to the cellular antennas. In FIG. 6, for convenience of explanation, only the NTN antennas (651, 653, 661) are described as transmitting and / or receiving only signals for NTN communication, and the NTN antennas (651, 653, 661) may also support signals associated with RATs different from NTN.A communication processor (610) (e.g., at least one of a first communication processor (212), a second communication processor (214), or an integrated communication processor (260)) can perform switching of NTN antennas (651, 653, 661) by controlling switches (671, 681). The first switch (671) can branch a line of signals so that, for example, a transmit (Tx) signal for NTN communication is provided to the first NTN transmit antenna (651) or the third NTN transmit antenna (661). A diplexer (672) can be placed between the first switch (671) and the third NTN transmit antenna (661) and can separate a receive (Rx) signal associated with NTN communication and a transmit signal associated with NTN communication. The diplexer (672) may be implemented as a duplexer including bandpass filters. The second switch (681) may branch the line of signal so that, for example, a transmission signal for NTN communication is provided to the second NTN transmission antenna (653) or the third NTN transmission antenna (661). If a user of the electronic device (101) is in a distress phase (e.g., a distress phase), or if a cellular network (e.g., 2G, 3G, LTE, and / or 5G network) cannot be identified (e.g., no service), or if a local area network (LAN) cannot be used, the electronic device (101) may transmit an emergency message based on NTN communication provided from a satellite. The NTN communication may be, for example, NB-IoT (narrow band internet of things) NTN communication according to 3GPP standards (e.g., rel. 17), but is not limited thereto. In one embodiment, the electronic device (101) may support both NB-IoT NTN communication and NR (new radio) NTN communication.

[0085] According to one embodiment, the communication processor (610) may transmit a baseband signal to an RFIC (620) (e.g., at least one of a first RFIC (222), a second RFIC (224), a third RFIC (226), or a fourth RFIC (228)) and / or receive a baseband signal. The communication processor (610) may check a time window (or a timer corresponding to the time window) for managing SAR (or time average SAR) for TAS feature operation. The communication processor (610) may determine (or check) a transmitting antenna for a transmission signal associated with a cellular network communication or NTN based on information associated with the time window (e.g., information indicating whether the timer has expired). The RFIC (620) may process at least one RF signal associated with at least one RF path. Here, the RF path may include at least one piece of hardware for transmitting an RF signal (e.g., at least one of an RFIC, an RFFE, or an antenna). For example, the RFIC (620) may receive a baseband signal from the communication processor (610) and generate an RF signal based on the baseband signal (or perform up-conversion on the baseband signal). The RFIC (620) may also control the first RFFE (630) and / or the second RFFE (640) based on a control signal provided by the communication processor (610). Although the RFIC (620) is depicted as being one module (or a chip containing processing circuits) in the example of FIG. 6, those skilled in the art will understand that this is exemplary and there is no limit to the number of modules in which the RFIC (620) is implemented. According to one embodiment, the RFIC (620) can provide the generated RF signal to the first RFFE (630) and / or the second RFFE (640).The first RFFE (630) and / or the second RFFE (640) may process (e.g., amplify) the provided RF signal. The first RFFE (630) and / or the second RFFE (640) may be implemented as an LPAMiD (low-noise amplifier and power amplifier module including duplexers) comprising at least one power amplifier, a plurality of LNAs, a duplexer (or bandpass filter), and an antenna switching module (e.g., a path connection corresponding to the band), but is not limited thereto. In one embodiment, one RFFE may perform processing of a plurality of RF signals (e.g., RF signals of a plurality of RATs or a plurality of bands). The first RFFE (630) may amplify the RF signal of the first band (e.g., B255) provided by the RFIC (620) or amplify the RF signal of the first band or the second band received through the third NTN transmitting antenna (661). The second RFFE (640) may amplify the RF signal of the second band (e.g., B256) provided by the RFIC (620), amplify the RF signal of the first band received through the first NTN transmitting antenna (651), or amplify the RF signal of the second band received through the second NTN transmitting antenna (653). In FIG. 6, the first RFFE (630) or the second RFFE (640) is illustrated as amplifying the transmission signal of a designated band, but is not limited thereto. For example, when the electronic device (101) performs transmit (Tx) MIMO, the first RFFE (630) and the second RFFE (640) may amplify the RF signal of the first band at least simultaneously. When the electronic device (101) performs transmit MIMO, the first RFFE (630) and the second RFFE (640) may amplify the RF signal of the second band at least simultaneously.

[0086] According to one embodiment, the communication processor (610) may be referred to as a processor. The communication processor (610) may include at least one processing circuitry. In this document, the description that the communication processor (610) (or processor) can perform any operation (or function, task, or operation) may be interpreted substantially as meaning that an instruction (or command, computer program) causing the electronic device (101) (or communication processor (610)) to perform said operation is stored in memory (e.g., non-volatile memory, storage). Additionally, the description that the communication processor (610) can perform any operation may be interpreted substantially as meaning that at least one processor, without a fixed number, can perform said operation individually or collectively.

[0087] According to one embodiment, the first RFFE (630) may be connected to the first switch (671), and the output terminal of the first switch (671) may be connected to the first NTN transmitting antenna (651) or the third NTN transmitting antenna (661). The first switch (671) may be configured to selectively connect the first RFFE (630) to the first NTN transmitting antenna (651) or the third NTN transmitting antenna (661). When the first RFFE (630) and the first NTN transmitting antenna (651) are connected through the first switch (671), the RF signal output from the first RFFE (630) may be provided to the first NTN transmitting antenna (651) through the diplexer (673). When the first RFFE (630) and the third NTN transmitting antenna (661) are connected through the first switch (671), the RF signal output from the first RFFE (630) can be provided to the third NTN transmitting antenna (661) through the diplexer (672). In FIG. 6, the first switch (671) is illustrated as an exemplary SPDT (single pole double throw) switch, and the first switch (671) can be implemented as an SPNT switch corresponding to the number of transmission paths of the RF signal output from the first RFFE (630).

[0088] In one embodiment, the first RFFE (630) may include a first power amplifier (631), antenna switching modules (634, 636), low-noise amplifiers (LNAs) (632, 633), and a band-pass filter (635). The RF signal of the first band (or transmission (Tx) signal) provided by the RFIC (620) may be amplified by the first power amplifier (631). The signal amplified by the first power amplifier (631) may be provided to the first NTN transmission antenna (651) through the antenna switching module (634), the first switch (671), and the diplexer (673) when the first RFFE (630) and the first NTN transmission antenna (651) are connected by the first switch (671). The signal amplified by the first power amplifier (631) can be provided to the third NTN transmitting antenna (661) through the antenna switching module (634), the first switch (671), the diplexer (672), and the antenna switching module (636) when the first RFFE (630) and the third NTN transmitting antenna (661) are connected by the first switch (671). In FIG. 6, the diplexer (672) is illustrated as being placed outside the first RFFE (630) as an example, but is not limited thereto. For example, the diplexer (672) may be implemented as being placed inside the first RFFE (630). The RF signal of the first band received through the third NTN transmitting antenna (661) can be provided to the LNA (633) through the antenna switching module (636) and the diplexer (672). The signal amplified by the LNA (633) can be provided to the RFIC (620). The RF signal of the second band received through the third NTN transmitting antenna (661) can be provided to the LNA (632) through the antenna switching module (636) and the band-pass filter (635) ("BPF"). The RF signal amplified by the LNA (632) can be provided to the RFIC (620).The RFIC (620) can generate a baseband signal (or perform down conversion on the RF signal) based on the RF signal provided by the first RFFE (630). The RFIC (620) can provide the generated baseband signal to the communication processor (610).

[0089] According to one embodiment, the second RFFE (640) may be connected to the second switch (681), and the output terminal of the second switch (681) may be connected to the second NTN transmitting antenna (653) or the third NTN transmitting antenna (661). The second switch (681) may be configured to selectively connect the second RFFE (640) to the second NTN transmitting antenna (653) or the third NTN transmitting antenna (661). When the second RFFE (640) and the second NTN transmitting antenna (653) are connected through the second switch (681), the RF signal output from the second RFFE (640) may be provided to the second NTN transmitting antenna (653). When the second RFFE (640) and the third NTN transmitting antenna (661) are connected through the second switch (681), the RF signal output from the second RFFE (640) can be provided to the third NTN transmitting antenna (661) through the antenna switching module (636). In FIG. 6, the second switch (681) is illustrated as being an exemplary SPDT switch, and the second switch (681) can be implemented as an SPNT switch corresponding to the number of transmission paths of the RF signal output from the second RFFE (640).

[0090] In one embodiment, the second RFFE (640) may include a second power amplifier (641), antenna switching modules (644, 646), LNAs (642, 643), and a band-pass filter (645). The RF signal (or Tx signal) of the second band provided by the RFIC (620) may be amplified by the second power amplifier (641). The signal amplified by the second power amplifier (641) may be provided to the second NTN transmitting antenna (653) through the antenna switching module (644), the band-pass filter (682), the second switch (681), and the antenna switching module (646) when the second RFFE (640) and the second NTN transmitting antenna (653) are connected by the second switch (681). The signal amplified by the second power amplifier (641) can be provided to the third NTN transmitting antenna (661) through the antenna switching module (644), band pass filter (682), second switch (681), and antenna switching module (636) when the second RFFE (640) and the third NTN transmitting antenna (661) are connected by the second switch (681). The RF signal of the first band received through the first NTN transmitting antenna (651) can be provided to the LNA (643) through the diplexer (673). The signal amplified by the LNA (643) can be provided to the RFIC (620). The RF signal of the second band received through the second NTN transmitting antenna (653) can be provided to the LNA (642) through the antenna switching module (646) and band pass filter (645). The RF signal amplified by the LNA (642) can be provided to the RFIC (620). The RFIC (620) can generate a baseband signal (or perform down-conversion on the RF signal) based on the RF signal provided by the second RFFE (640). The RFIC (620) can provide the generated baseband signal to the communication processor (610).

[0091] In one embodiment, the first NTN transmitting antenna (651), the second NTN transmitting antenna (653), and the third NTN transmitting antenna (661) may be positioned at different locations on (or inside) the housing of the electronic device (101). The positions where the first NTN transmitting antenna (651), the second NTN transmitting antenna (653), and the third NTN transmitting antenna (661) are positioned, and the definition of the antenna group, will be explained with reference to FIGS. 7a, 7b, and 7c.

[0092] Referring to FIG. 7a, in one embodiment, the electronic device (101) may include a plurality of antennas (651, 653, 661, 721, 722, 723, 741, 742, 743) included on (or inside) the housing of the electronic device (101). In the example of FIG. 7a, some of the antennas included in the electronic device (101) are shown for convenience of explanation regarding antenna groups, and those skilled in the art will understand that the electronic device (101) may include a greater number of antennas than those shown in FIG. 7a. Each of the antennas (651, 653, 661, 721, 722, 723, 741, 742, 743) may be placed inside the housing and / or placed in a part of the housing. At least some of the antennas (651, 653, 661, 721, 722, 723, 741, 742, 743) may be placed on the outer surface of the housing of the electronic device (101), but are not limited thereto. In one example, the antennas (741, 661) may be placed on one side (e.g., bottom) of the housing of the electronic device (101) and the antennas (651, 653) may be placed on the other side (e.g., top) of the housing of the electronic device (101), but this is exemplary.

[0093] In one embodiment, antennas (651, 653) for NTN communication may be positioned on the top (703) of the electronic device (101). The electronic device (101) may obtain a good quality NTN communication channel between the electronic device (101) and the satellite by radiating a transmission signal for NTN communication in a direction toward the satellite (or upward direction) through any one of the antennas (651, 653) positioned on the top (703). For example, if the electronic device (101) is located in an area where NTN communication of the first band is performed, the electronic device (101) may radiate a transmission signal for NTN communication of the first band through the first antenna (651). If the electronic device (101) is located in an area where NTN communication of the second band is performed, the electronic device (101) may radiate a transmission signal for NTN communication of the second band through the second antenna (653). In one embodiment, if the electronic device (101) is located in an area where both the first band and the second band are supported, the electronic device (101) may radiate a transmission signal for NTN communication of the first band or the second band based on selectively using the first antenna (651) or the second antenna (653). In one embodiment, antennas (721, 722, 723) for RAT (e.g., cellular network communication) different from NTN communication may be placed on the upper part (705) of the electronic device (101) (or in a location adjacent to the antennas (651, 653) for NTN communication). An antenna for cellular network communication may be additionally placed on the upper part (705) of the electronic device (101) due to the performance of transmit hopping (Tx hopping), support for uplink ("UL") MIMO, or extension of the frequency band (e.g., Sub6 UHB (ultra high band)).The electronic device (101) can perform transmit hopping, perform uplink MIMO operations, or radiate transmit signals for cellular network communication of various frequency bands through cellular antennas (741, 742, 743) placed in the lower part (709) and / or cellular antennas (721, 722, 723) placed in the upper part (705). In one embodiment, because the antennas (651, 653) for NTN communication in the upper part (703) and the antennas (721, 722, 723) for cellular network communication in the upper part (705) are placed in adjacent positions, there is a risk that the electronic device (101) may generate a SAR exceeding a threshold SAR based on SAR specifications. In one embodiment, the electronic device (101) may be required to restrict the transmission of a signal for NTN communication until a timer corresponding to a time window (e.g., 60 seconds, 100 seconds, or 360 seconds) for calculating a SAR value (e.g., a time-averaged SAR value) of cellular network communication expires in order to satisfy a threshold SAR condition based on a SAR specification. If the electronic device (101) restricts the transmission of a signal for NTN communication until the timer corresponding to a time window for checking a TAS value expires, a transmission delay of a time interval corresponding to the timer (e.g., about 60 seconds to about 360 seconds) may occur. In one embodiment, the electronic device (101) may be required to restrict the transmission of a signal for cellular network communication until a timer corresponding to a time window for checking a SAR value expires after transmitting a signal for NTN communication. The SAR value for NTN communication may be managed based on non-TAS function operation. When the electronic device (101) limits the transmission of a signal for cellular network communication until the expiration of a timer corresponding to a time window for checking the SAR value, a transmission delay of the time interval corresponding to the timer may occur.The electronic device (101) may be required to reduce the target SAR (or Plimit) for cellular network communication by a value corresponding to the SAR margin for NTN communication in order to prevent transmission delay. When transmission of a signal for NTN communication is required, the electronic device (101) may increase the target SAR value for cellular network communication (or set the target SAR to a value corresponding to the threshold SAR based on the SAR specification) by using antennas (651, 653) placed at the top (703) and antennas (661) included in a group of antennas separated temporally and / or spatially.

[0094] In one embodiment, the electronic device (101) can determine whether the transmission operation of an RF signal by the electronic device (101) violates a limiting rule (e.g., a SAR limiting rule) based on the sum of RF exposures (e.g., a radio frequency exposure) (e.g., a SAR and / or a PD (power density)) generated by an antenna group including a plurality of antennas. For example, whether to determine whether to violate a limiting rule (e.g., a SAR limiting rule) based on the sum of RF exposures generated by a plurality of antennas, or whether to determine whether each of the RF exposures generated by a plurality of antennas independently violates a limiting rule, can be determined by the following Equation 1.

[0095]

[0096] The above mathematical formula 1 is merely an example to aid understanding, and embodiments of the present disclosure are not limited thereto. For example, the above mathematical formula 1 may be modified, applied, or extended in various ways.

[0097] In Equation 1, SAR1 is the SAR generated by one antenna and SAR2 is the SAR generated by another antenna, and their units may be, for example, W / kg. The value corresponding to the left side of Equation 1 may be referred to as SPLSR (SAR to peak location separation ratio). R for the sum of various SARs may be, for example, as shown in Table 3. Meanwhile, the values ​​of 1.5 and 0.04 in Equation 1 are merely exemplary and are not limited.

[0098] Total SAR (SAR1 + SAR2) (W / Kg) Minimum Separation Distance (Minimum R Value) (mm) 3.2 14 32.8 11 72.4 9 32 71 1.6 51 1.4 41 1.2 33 1.0 25 0.8 18

[0099] For example, assume a case where the sum of the SARs generated by two antennas is 3.2 W / Kg. Meanwhile, as both antennas are positioned, for example, at the top of the electronic device (101), the distance between them may be less than 143 mm. In this case, in order to determine whether there is a momentary violation of the SAR regulation in the electronic device (101) or a cumulative violation of the SAR regulation, it may be necessary to determine whether the sum of the SARs generated by the two antennas violates the SAR regulation. To ensure compliance with the SAR regulation, for example, the electronic device (101) may perform back-off associated with the transmission power of the RF signal based on either of the two antennas. Meanwhile, when an RF signal of FR (frequency range) 2 is transmitted, power density (PD) may be used instead of SAR. For example, those skilled in the art will understand that when SAR and PD are considered simultaneously, the sum of RF exposures can be determined as the sum of SAR divided by the maximum SAR and PD divided by the maximum PD, and the minimum separation distance corresponding to the sum of RF exposures can be determined. Those skilled in the art will understand that RF exposures in this disclosure may mean, for example, SAR, PD, TRP (total radiated power), and / or EIRP (effective isotropic radiated power). Those skilled in the art will understand that RF exposures may be referred to, for example, as RF radiation or RF intensity, and that there are no limitations on such designations. For example, there are no limitations on the reference points of each antenna for defining the distance between the antennas. For example, the reference point may be set in various ways, such as the point where the maximum RF is generated among the antennas, the center of mass of the antenna, or a point at one end of the antenna, and there are no limitations on the method of setting.According to one embodiment, as each of the two antennas is positioned, for example, at the bottom and top of the electronic device (101), the distance between them may be 143 mm or more. 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 SARs generated from either of the two antennas violates the SAR regulation and / or whether the sum of SARs generated from the other of the two antennas violates the SAR regulation. As described above, antennas for which the sum of SARs is considered to determine whether the SAR regulation is violated as satisfying Equation 1 may be referred to as "antennas included in the same antenna group." They may be included in the same antenna group when the distance between the antennas is relatively small (e.g., smaller than the distance associated with Equation 1). Additionally, antennas for which independent SARs, rather than the sum of SARs, are considered to determine whether the SAR regulation is violated as not satisfying Equation 1 may be described as being included in a different antenna group. When the distance between antennas is relatively large (for example, when it is larger than the distance associated with Equation 1), they may be included in different antenna groups.

[0100] In one embodiment, antennas (651, 653) located at the top (703) of the electronic device (101) and antennas (661, 741, 742, 743) located near the bottom (707) may each be included in different antenna groups. Accordingly, the electronic device (101) can independently manage whether to back off (or limit the transmission of a transmission signal) based on RF exposure based on antennas (651, 653) and whether to back off (or limit the transmission of a transmission signal) based on RF exposure based on antennas (661, 741, 742, 743). For example, the electronic device (101) may set the transmitting antenna to antenna (651) at a first time point. The electronic device (101) may determine whether to restrict the transmission of a transmission signal through the antenna group to which the antenna (651) belongs, based on the amount of RF exposure associated with the antenna group to which the antenna (651) belongs (e.g., accumulated RF exposure at a past point in time). If the conditions for changing the transmission antenna at a second point in time are satisfied, the electronic device (101) may change the transmission antenna from the antenna (651) to the antenna (661). After the second point in time, the electronic device (101) may determine whether to restrict the transmission of a transmission signal through the antenna group to which the antenna (661) belongs, based on the amount of RF exposure associated with the antenna group to which the antenna (661) belongs (e.g., accumulated RF exposure at a past point in time). Meanwhile, the change of the transmission antenna may be referred to as transmission antenna switching. When the transmission signal is output by a plurality of power amplifiers, the change of the transmission antenna may be referred to as transmission antenna hopping. For example, the change of the transmitting antenna may be performed based on the control of a switch (e.g., the first switch (671) and / or the second switch (681)) and / or a change of an RF element (e.g., a power amplifier (PA)), and there are no limitations on the method.For example, if the communication processor (610) determines that it will change the transmitting antenna, the communication processor (610) may control at least some of the RF circuits (e.g., RFIC (620), RFFEs (630, 640), and / or switches (e.g., first switch (671) and / or second switch (681)).

[0101] According to one embodiment, antennas (651) and antennas (653) may be included in the same antenna group as the distance between each of the antennas (651, 653) does not satisfy Equation 1. As the distance between each of the antennas (651, 653) and each of the antennas (741, 742, 743, 661) satisfies Equation 1, antennas (651, 653) may be included in a different antenna group from antennas (741, 742, 743, 661). For example, antennas (651, 653) included at the top (703) of the electronic device (101) may be referred to as the first NTN antenna group (710). The antennas (661, 741, 742, 743) included in the lower part (709) based on the virtual center line (701) of the electronic device (101) can be referred to as the second antenna group (740).

[0102] In one embodiment, the antennas (741, 661, 742, 743) included in the second antenna group (740) can satisfy SPLSR with the NTN transmitting antennas (651, 653) of the upper (703) without lowering the target SAR value (or Plimit). The distance between the first NTN transmitting antenna (651) included in the first NTN antenna group (710) and the first main antenna (741) included in the second antenna group (740) may be, for example, about 157.84 millimeters (mm). The distance between the first NTN transmitting antenna (651) included in the first NTN antenna group (710) and the third NTN transmitting antenna (661) included in the second antenna group (740) may be about 149.04 millimeters (mm). The third NTN transmitting antenna (661) can support both NTN communication and cellular network communication, and when the third NTN transmitting antenna (661) is used as a transmitting antenna for a signal for cellular network communication, the third NTN transmitting antenna (661) may be referred to as the "second main antenna." Each of the first main antenna (741) and the second main antenna may satisfy an R (e.g., 143 mm) that satisfies the SPLSR corresponding to the SAR value of 3.2 W / kg in Table 3 with respect to the first NTN transmitting antenna (651). The first NTN transmitting antenna (651) may operate independently of the cellular antennas of the lower (709) (e.g., the first main antenna (741) and the second main antenna). In the same way, the first NTN transmitting antenna (651) may operate independently of the third main antenna (742) and the fourth main antenna (743).

[0103] In one embodiment, by reducing the target SAR for non-TAS function operation, the electronic device (101) can independently manage the SAR values ​​(e.g., time-averaged SAR values) of the cellular antennas (e.g., 721, 722, 723) included in the first cellular antenna group (720) and the SAR values ​​of the second NTN transmitting antenna (661). The first NTN transmitting antenna (651) and the second NTN transmitting antenna (653) can support both NTN communication and cellular network communication. When the first NTN transmitting antenna (651) is used as a transmitting antenna for cellular network communication, it may be referred to as the "first sub-antenna." When the second NTN transmitting antenna (653) is used as a transmitting antenna for cellular network communication, it may be referred to as the "second sub-antenna." The electronic device (101) can spatially separate antennas for TAS function operation and antennas for non-TAS function operation by setting the maximum time-averaged SAR value satisfying SPLSR for the transmitting antenna (741) for NTN communication in the lower part (709) and the target SAR value of the cellular antennas (721, 722, 723, 651, 653) located in the upper part (705). The electronic device (101) may refer to the first antenna group (730) by encompassing the first NTN antenna group (710) and the first cellular antenna group (720). The electronic device (101) can reduce the risk of signal transmission delay through temporal separation between the cellular antenna for TAS function operation and the NTN transmitting antenna for non-TAS function operation.

[0104] Referring to FIG. 8, in one embodiment, an example is illustrated in which an electronic device (101) transmits (800) a signal for cellular network communication or a signal for NTN communication. When transmission of a signal for NTN communication is required, the electronic device (101) can check whether the TAS timer of the first antenna group (730) has expired. The electronic device (101) can check that a signal for cellular network communication is transmitted (810_1) through the cellular antenna of the first antenna group (730) before the time interval corresponding to the TAS timer has elapsed. Based on confirming that the TAS timer of the first antenna group (730) has not expired, the electronic device (101) can perform antenna switching of the NTN transmitting antenna. Based on antenna switching, the electronic device (101) can transmit (820) a signal for NTN communication through the NTN transmitting antenna (661) of the second antenna group (740).

In one embodiment, the electronic device (101) can check whether the non-TAS timer of the first antenna group (730) has expired when transmission of a signal for cellular network communication is required.The electronic device (101) can determine whether a time interval corresponding to a non-TAS timer (e.g., 360 seconds) has elapsed from the time point (T1) when a signal associated with NTN communication is transmitted through the NTN transmitting antenna of the first antenna group (730). The electronic device (101) can perform antenna switching of the cellular antenna based on the determination that the non-TAS timer has not expired.

The condition set for the TAS function may include that a timer corresponding to the TAS time window has expired. The electronic device (101) can, for example, check an antenna (or antenna group) that transmitted a signal associated with cellular network communication during the previous TAS time window.
