Description

A method for determining an electronic device and an antenna group used for non-terrestrial network communication of the electronic device based on the total exposure ratio

[0001] The present disclosure relates to an electronic device and a method of operating the electronic device, and more specifically to a technique for determining an antenna group used for non-terrestrial network communication based on a total exposure ratio.

[0002] A wireless communication device may be required to limit wireless signal exposure that exceeds a wireless signal exposure limit value. The wireless signal exposure limit value may include power limit values ​​set by domestic or international regulatory bodies. Wireless signal exposure may be expressed as a specific absorption rate (SAR), which represents energy absorption by human tissue per unit mass. Wireless signal exposure may be expressed as a power density (PD), which represents energy absorption per unit area. In an electronic device using various wireless communication methods in multiple frequency bands, a total exposure ratio (TER) may be used, which combines the wireless signal exposures of multiple signals corresponding to each wireless communication method. The TER may be expressed in a combined form of the SAR distribution and the PD distribution.

[0003] The information described above may be provided as related art for the purpose of aiding understanding of this document. None of the above is to be claimed as prior art related to this document, nor can it be used to determine prior art.

[0004] The electronic device may include a plurality of antenna groups that support non-terrestrial network communication. The electronic device may determine whether to perform non-terrestrial network communication based on which of the plurality of antenna groups. In determining the antenna group to be used for non-terrestrial network communication, the electronic device may verify whether the antenna group satisfies regulations related to the total exposure ratio (TER). When the electronic device determines the antenna group to be used for non-terrestrial network communication, it may minimize the path loss of the antenna group used for non-terrestrial network communication.

[0005] The technical problems to be solved in this document are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this invention belongs from the description below.

[0006] According to one embodiment, the electronic device may include a display. The electronic device may include a communication circuit that supports non-terrestrial wireless communication. The electronic device may include a first antenna group. The electronic device may include a second antenna group. The electronic device may include a memory that stores at least one computer program including instructions. The electronic device may include at least one processor. When the at least one computer program is executed individually or collectively by the at least one processor, the electronic device may check the total exposure ratio (TER) or maximum power transmission time of each of the first antenna group and the second antenna group in response to the reception of a non-terrestrial network communication connection request. The at least one computer program may allow the electronic device to check whether each of the first antenna group and the second antenna group satisfies a TER condition for maintaining a TER below the maximum allowable TER, based on the TER or maximum power transmission time of each of the first antenna group and the second antenna group. At least one computer program may enable an electronic device to select an antenna group to be used for performing non-terrestrial network communication based on whether at least one of the first antenna group and the second antenna group satisfies the TER condition and the priority of the first antenna group and the second antenna group.

[0007] A method for determining an antenna group used for non-terrestrial network communication of an electronic device, according to one embodiment, may include an operation of checking the total exposure ratio (TER) or maximum power transmission time of each of the first antenna group and the second antenna group in response to the reception of a request for non-terrestrial network communication connection. The method may include an operation of checking whether each of the first antenna group and the second antenna group satisfies a TER condition for maintaining a TER less than the maximum allowable TER, based on the TER or maximum power transmission time of each of the first antenna group and the second antenna group. The method may include an operation of selecting an antenna group to be used for performing non-terrestrial wireless communication based on whether at least one of the first antenna group and the second antenna group satisfies the TER condition and the priority of the first antenna group and the second antenna group.

[0008] The electronic device can determine whether each of the first antenna group and the second antenna group satisfies the TER condition based on the TER or maximum power transmission time of each of the first antenna group and the second antenna group. The electronic device can establish a non-terrestrial network communication connection through the antenna group that satisfies the TER condition and has a higher priority among the first antenna group and the second antenna group. The electronic device can perform a non-terrestrial network communication connection while satisfying regulations related to TER. Additionally, when the electronic device determines the antenna group used for non-terrestrial network communication, it can minimize path loss of the antenna group used for non-terrestrial network communication by outputting information indicating that a change in the placement of the electronic device is required.

[0051] FIG. 5 is a drawing for explaining the TER of an electronic device according to one embodiment.

[0052] The electronic device (100) may be required to limit wireless signal exposure that exceeds a wireless signal exposure limit value. The wireless signal exposure limit value may include a power limit value set by domestic or international regulatory bodies. Wireless signal exposure according to one example may be expressed as a specific absorption rate (SAR), which represents energy absorption by human tissue per unit mass. SAR may have units of W / kg (watts per kilogram). SAR may be used to represent wireless signal exposure caused by a signal transmitted by the electronic device (100) to perform wireless communication technologies such as 3G (e.g., CDMA), 4G, or IEEE 802.11ac. Wireless signal exposure according to one example may be expressed as a power density (PD), which represents energy absorption per unit area. PD is W / m² 2 It can have units. PD can be used to indicate radio signal exposure for transmission frequencies, including wireless communication technologies such as IEEE 802.11ad or 5G. SAR exposure limit values ​​and PD exposure limit values ​​can be set as shown in [Table 1].

[0054] An electronic device (100) can transmit multiple signals based on at least one wireless communication technology. In a situation where the electronic device (100) transmits multiple signals, a user of the electronic device (100) may be exposed to the electromagnetic waves of each of the multiple signals. In a situation where the electronic device (100) transmits multiple signals based on at least one wireless communication technology, the electronic device (100) must comply with a wireless signal exposure limit value. For example, in a situation where the electronic device (100) transmits signals at transmission frequencies below 6 GHz and transmission frequencies above 6 GHz, it must evaluate wireless signal exposure caused by signals at transmission frequencies below 6 GHz and transmission frequencies above 6 GHz and comply with a wireless signal exposure limit value. The SAR must be limited such that the combined value of the SARs for each of the multiple frequency bands is less than the exposure limit value of the SAR. The SARs for each of the multiple frequency bands may be normalized by the exposure limit value of the SAR. PDs for each of the multiple frequency bands must be limited such that the combined value of the PDs for each of the multiple frequency bands is less than the exposure limit value of the PD. The PDs for each of the multiple frequency bands may be normalized by the exposure limit value of the PD. The electronic device (100) may use a total exposure ratio (TER) that combines the wireless signal exposures of each of the multiple signals to evaluate and comply with the wireless signal exposure of each of the multiple signals corresponding to each of at least one wireless communication technology. The TER may be expressed in a combined form of SARs for each of the multiple frequency bands and PDs for each of the multiple frequency bands, as in [Equation 1].

[0055]

[0056] In [Equation 1], i represents the frequency band, and SAR i represents the SAR for the i-th frequency band, and PDi represents the PD for the i-th frequency band. SAR limit and / or PD limit represents a wireless signal exposure limit value set by domestic or international regulatory bodies. TER (510) is the exposure limit value of SAR (SAR) corresponding to each frequency band. limit SAR normalized by ) ) and / or the exposure limit value of PD (PD limit PD normalized by ) It can refer to a value that combines ).

[0057] SAR of [Mathematical Formula 1] i is together with T as in [Equation 2] SAR It can be expressed as the average value of the transmitted power over the time interval T SAR can refer to the length of the time window, which is the time interval for measuring SAR.

[0058]

[0059] PD of [Mathematical Formula 1] i is as in mathematical equation 3, T PD It can be expressed as the average value of the transmitted power over the time interval T PD can refer to the length of the time window, which is the time interval for measuring PD.

[0060]

[0061] The electronic device (100) may maintain the TER to be less than (or less than) a specified size (e.g., 1) which is the maximum allowable TER (501) in order to comply with wireless signal exposure limit values ​​set by domestic or international regulatory bodies. For example, the electronic device (100) may limit the TER (510) to satisfy [Equation 4].

[0062]

[0063] According to one embodiment, the electronic device (100) is SAR i SAR limit Exceeding or PD i PD Ga limit Even if a situation occurs where it exceeds, the time-averaged SAR as in Equations 3 and 4 i and time-average PD i Because it calculates, the TER can be kept below a specified size (e.g., 1) which is the maximum allowable TER (501). The electronic device (100) can satisfy the wireless signal exposure limit value set by the regulatory authority by keeping the TER below the maximum allowable TER (501) (e.g., 1).

[0064] FIG. 5 describes a situation in which an electronic device (100) performs non-terrestrial network communication after performing terrestrial network communication, but it should be understood that the contents of the present disclosure are not applicable only to situations in which terrestrial network communication is switched while performing non-terrestrial network communication, but can be applied to all situations in which the electronic device (100) starts a communication connection. For example, it can be applied to situations in which additional communication is performed while the electronic device performs non-terrestrial network communication and terrestrial network communication simultaneously, or to situations in which terrestrial network communication is performed after performing non-terrestrial network communication.

[0065] The electronic device (100) can perform a non-terrestrial network communication connection in response to a request for a non-terrestrial network communication connection. For example, the electronic device (100) can perform a non-terrestrial network communication connection after performing terrestrial network communication. In the situation where the electronic device (100) performs a non-terrestrial network communication connection, the electronic device (100) can satisfy a wireless signal exposure limit value set by a regulatory authority by keeping the TER (510) below the maximum allowable TER (e.g., 1). The electronic device (100) can calculate the TER (510) based on the transmission power of the terrestrial network communication and the non-terrestrial network communication used during the time window. When the electronic device (100) performs a non-terrestrial network communication connection at a specific point in time (e.g., the point in time when terrestrial network communication is terminated (540)), it is necessary to use only the TER margin (512) (margin) that does not exceed the TER of the specific point in time (e.g., the point in time when terrestrial network communication is terminated (540)) excluding the TER (511) at the maximum allowable TER (501) (e.g., 1). The electronic device (100) can calculate the TER (511) at a specific point in time (e.g., the point in time when terrestrial network communication is terminated (540)) based on the transmission power (502) while the electronic device (100) performs terrestrial network communication. For example, the electronic device (100) can calculate the TER (511) at a specific point in time based on the time-average value of the transmission power included in the time interval of the time window up to a specific point in time (e.g., the point in time when terrestrial network communication is terminated (540)).

[0066] The TER margin (512) may represent the available TER for the electronic device (100). The electronic device (100) may calculate the TER margin based on the difference between the maximum allowable TER (501) (e.g., 1) and the previously used TER (e.g., the TER at a specific point in time (511)). The previously used TER (e.g., the TER at a specific point in time (511)) may refer to the TER calculated based on the transmission power used during the time interval of the time window until the previously used TER is identified.

[0067] According to one example, the electronic device (100) may be configured not to use a certain percentage of the maximum allowable TER (501). If the electronic device (100) is configured to use all of the maximum allowable TER (501), it may violate wireless signal exposure limit regulations set by regulatory authorities by using TER exceeding the maximum allowable TER (501). To prevent a situation where the electronic device (100) uses TER exceeding the maximum allowable TER (501), the electronic device (100) may be set aside as a reserved margin, which is TER configured to be used in a preset situation (e.g., a situation where TER is used exceeding the expected TER usage). The certain percentage of the maximum allowable TER (501) occupied by the reserved margin may be set by the manufacturer and may be a fixed value or a value that changes depending on the state of the electronic device (100). The TER margin (512) can be calculated differently depending on the proportion of the reserve margin in the maximum allowable TER (501). For example, if the reserve margin exists, the electronic device (100) can calculate the TER margin (512) based on the difference between the value obtained by subtracting the reserve margin from the maximum allowable TER (501) and the previously used TER. For example, if the proportion of the reserve margin in the maximum allowable TER (501) is 10%, the electronic device (100) can calculate the TER margin (512) based on 90% of the maximum allowable TER (501) and the difference between the previously used TER.

[0068] The electronic device (100) may be maintained in a minimum transmission power mode after performing terrestrial network communication and before connecting to a non-terrestrial network communication. The minimum transmission power mode may refer to a mode in which the transmission power for performing communication is maintained at the lowest level. As time progresses, the proportion of time in the minimum transmission power mode within the time window (503), which is the time interval for measuring TER (510), may increase. For example, the proportion of time in the minimum transmission power mode may increase from the point in time (540) when the minimum transmission power mode started until a certain time has elapsed (e.g., the point in time (550)) when there is a TER margin equal to the TER (520) required by a non-terrestrial network communication connection request). As time progresses, the TER (510) may decrease as the proportion of time in which the electronic device (100) performs terrestrial network communication within the time window (503) decreases.

[0069] According to one example, the electronic device (100) may perform a non-terrestrial network communication connection at a time (560) after a time window (503) has elapsed while maintaining the lowest transmission power mode (TER) (510). The electronic device (100) may calculate the TER (510) based on the transmission power of the lowest transmission power mode when it maintains the lowest transmission power mode for a time window (503). Since the above lowest transmission power mode is merely an example, it should be understood that the contents of the present disclosure may apply not only when the electronic device (100) of the present disclosure is in the lowest transmission power mode, but also in situations where the calculated TER is reduced.

[0070] The time window (503), which is the time interval for measuring TER (510), can be determined as a time interval set by domestic or international regulatory bodies. The time window (503) can be determined as shown in Table 2.

[0071] Area SAR Time Window (Unit: sec) PD Time Window (Unit: sec) Frequency 3GHz or less Frequency Over 3GHz 6GHz or less Frequency 10GHz or less Frequency Over 3GHz North America (FCC) 10060304 Canada (ISED) 360360-- Japan (TELEC) 360360360360 China (NAL) / (NCC) 360360360360 Europe (RED) 360360-- Korea (KC) 360360360 (minute)Global(FCC or RED)----

[0072] For example, when the electronic device (100) calculates the TER (510) according to the time window (e.g., 100 seconds) (503) according to North America (FCC), it can perform a non-terrestrial network communication connection after maintaining the lowest transmission power mode for a time window (e.g., 100 seconds) (503). The TER (510) used when performing terrestrial network communication may not be reflected in the TER (510) as time window (e.g., 100 seconds) (503) elapses. Even if the electronic device (100) performs a non-terrestrial network communication connection, it can satisfy the wireless signal exposure limit value because the TER based on the power transmitted in the terrestrial network communication is not reflected. The electronic device (100) can perform a non-terrestrial network communication connection when the TER condition is satisfied, even without waiting for a time window (e.g., 100 seconds) (503). Referring to FIG. 5, the electronic device (100) may perform a non-terrestrial network communication connection at a time (550) when there is a TER margin equal to the TER (520) required in response to a non-terrestrial network communication connection request, which is the time when the TER condition is satisfied. The TER condition of the present disclosure may include a condition for the electronic device (100) to satisfy regulations related to TER when performing a communication connection (e.g., a non-terrestrial network communication connection). Satisfying regulations related to TER may include satisfying wireless signal exposure limit values ​​(e.g., SAR exposure limit values ​​and PD exposure limit values ​​of [Table 1]) set by domestic or international regulatory bodies. For example, the TER condition may refer to a condition where the TER is less than the maximum allowable TER. The TER condition may include a condition where the TER margin exceeds the TER (520) required in response to a non-terrestrial network communication connection request.The TER condition may include one of the following: a condition in which the TER margin exceeds a set value indicating the TER required for a non-terrestrial network communication connection, or a condition in which the maximum power transmission time exceeds the minimum time required for a non-terrestrial network communication connection. The TER margin may be a value used to determine whether the electronic device (100) satisfies the TER condition. The TER margin may refer to the maximum available TER of the electronic device such that the TER calculated according to the transmission power of the electronic device (100) is less than the maximum allowable TER. For example, the TER margin may be a value related to the maximum power output to perform non-terrestrial wireless communication. The electronic device (100) may perform a communication connection using transmission power such that a TER that does not exceed the TER margin is consumed (or calculated). According to one example, the TER margin may be calculated as the difference between the maximum allowable TER and the TER used during the time window time interval. The TER condition will be described in detail in FIG. 8.

[0073] An electronic device (100) according to one embodiment can check the time average TER during the time window up to the point (540) when the ground network communication is terminated to perform a non-ground network communication connection. The electronic device (100) can check the TER (510) even while maintaining the lowest transmission power mode to perform a non-ground network communication connection. The electronic device (100) can perform a non-ground network communication connection from the point (550) when there is a TER margin equal to the TER (520) required according to the non-ground network communication connection request.

[0074] Since the electronic device (100) performs a non-terrestrial network communication connection from the point in time (550) when there is a TER margin equal to the TER (520) required in response to a request for a non-terrestrial network communication connection, it may not exceed the wireless signal exposure limit value set by the regulatory authority when making a non-terrestrial network communication connection.

[0075] FIG. 6 is a drawing for illustrating an antenna group of an electronic device according to one embodiment.

[0076] An electronic device (600) (e.g., the electronic device (100) of FIG. 1) may include a plurality of antenna groups, including a first antenna group (610) and / or a second antenna group (620). At least a portion of the conductive portions (611, 612, 613, 614, 615) forming the exterior of the upper portion of the housing of the electronic device (600) may be configured to operate as at least a portion of at least one antenna included in the first antenna group (610). At least a portion of the conductive portions (621, 622, 623, 624, 625) forming the exterior of the lower portion of the housing of the electronic device (600) may be configured to operate as at least a portion of at least one antenna included in the second antenna group (620).

[0077] The first antenna group (610) and / or the second antenna group (620) may be connected to a ground network through a ground wireless communication device included in the ground network (e.g., the ground wireless communication device (210) of FIG. 2). The electronic device (600) may control the first antenna group (610) and / or the second antenna group (620) to transmit or receive data to or from the ground wireless communication device (210). The first antenna group (610) and / or the second antenna group (620) may be connected to a non-ground network through a non-ground wireless communication device included in the non-ground network (e.g., the non-ground wireless communication device (220) of FIG. 2). The electronic device (600) may control the first antenna group (610) and / or the second antenna group (620) to transmit or receive data to or from the non-ground wireless communication device (220).

[0078] The first antenna group (610) and the second antenna group (620) may be arranged to satisfy the SAR to peak location separation ratio (SPLSR) condition. The SPLSR condition may refer to a condition where the SPLSR of [Equation 5] is less than a specified value. For example, the specified value may be 0.04.

[0079]

[0080] In [Equation 5], D is the minimum distance between antenna groups, SAR SA 1 may refer to the standalone SAR value measured when the first antenna group (610) transmits a signal independently. SAR SA 2 may refer to the SAR value measured when the second antenna group (620) transmits a signal independently. For example, SAR SA 1 and SAR SA 2 is the maximum allowable SAR value (e.g., SAR limit It can be a value like ).

[0081] The first antenna group (610) and the second antenna group (620) satisfying the SPLSR condition may not affect each other regarding whether the TER condition is satisfied. For example, the TER of the first antenna group (610) may be determined by the transmission power of the antennas included in the first antenna group (610), and the transmission power of the antennas included in the second antenna group (620) may not be reflected. The TER of the second antenna group (620) may be determined by the transmission power of the antennas included in the second antenna group (620), and the transmission power of the antennas included in the first antenna group (610) may not be reflected.

[0082] The electronic device (600) can perform non-terrestrial or terrestrial network communication connections through two antenna groups satisfying SPLSR conditions. The electronic device (600) can perform non-terrestrial or terrestrial network communication connections through another antenna group satisfying TER conditions even when one antenna group does not satisfy TER conditions. Additionally, if both antenna groups satisfy TER conditions, the electronic device (600) can perform non-terrestrial or terrestrial network communication connections through the antenna group with higher priority.

[0083] FIG. 7 is a block diagram of an electronic device according to one embodiment.

[0084] According to one embodiment, an electronic device (700) (e.g., electronic device (100) of FIG. 1, electronic device (600) of FIG. 6) may include a processor (710) (e.g., processor (110) of FIG. 1), a memory (720) (e.g., memory (120) of FIG. 1), a first antenna group (610), and / or a second antenna group (620). Various embodiments of this document may be implemented even if some of the illustrated configurations are omitted or substituted with other configurations. In addition to the illustrated configurations, the electronic device (100) may further include at least some of the configurations and / or functions of the electronic device (100) of FIG. 1. At least some of each of the illustrated (or unillustrated) components of the electronic device (100) may be operatively, functionally, and / or electrically connected.

[0085] The processor (710) may include an application processor (711) and / or a communication processor (e.g., CP (118) of FIG. 1) (712). The processor (710) may include at least one processing circuitry, and the processor (710) may include at least one processor. The operations described in FIG. 1 through 14 may be performed individually or collectively by at least one processor (e.g., application processor (711), communication processor (712)) included in the processor (710). According to one example, the application processor (711) and / or communication processor (712) may be integrated into a single processor (710).

[0086] An electronic device (e.g., the electronic device (100) of FIG. 1, the electronic device (600) of FIG. 6) can transmit and / or receive data to and from a non-terrestrial network (e.g., the non-terrestrial network system (400) of FIG. 4) through a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2).

[0087] The electronic device (700) may include a communication processor (e.g., the communication processor (612) of FIG. 6) that controls a first antenna group (610) and / or a second antenna group (620) that supports a terrestrial network and / or a non-terrestrial network, and an application processor (611) that controls the communication processor (612). The application processor (711) may perform (or execute) various functions provided by an application that supports a service using a non-terrestrial network. The application may be an application that supports a service using a non-terrestrial wireless communication according to various causes (e.g., user input to activate a service via non-terrestrial wireless communication, or non-terrestrial wireless communication automatically activated according to specific conditions). According to one example, the application may support a service that transmits and / or receives data via non-terrestrial wireless communication, and the data may be various data including text messages, video messages, and voice messages.

[0088] The memory (720) can store at least one computer program, and at least one computer program may include instructions that can be executed by the processor (710). The operations described in FIGS. 1 through 14 can be performed according to the execution of instructions contained in the memory (720).

[0089] FIG. 8 is a diagram illustrating the operation of an electronic device determining a set value according to one embodiment.

[0090] It should be understood that the operation of the electronic device (700) described in FIG. 8 is an operation that can be performed by the electronic device (100) of FIG. 1, the electronic device (600) of FIG. 6, the electronic device (700) of FIG. 7 and / or the electronic devices of FIG. 9, FIG. 10, FIG. 11a, FIG. 11b, FIG. 12, FIG. 13a, FIG. 13b, and FIG. 14.

[0091] The electronic device (700) can perform non-terrestrial network communication connections through an antenna group (e.g., a first antenna group (610) or a second antenna group (620)) included in the electronic device (700). For example, the electronic device (700) can perform non-terrestrial network communication connections when an antenna group (e.g., a first antenna group (610) or a second antenna group (620)) included in the electronic device (700) satisfies TER conditions. Performing non-terrestrial network communication connections when the first antenna group (610) and / or the second antenna group (620) satisfies TER conditions may be intended to limit wireless signal exposure that exceeds a wireless signal exposure limit value. The electronic device (700) can check whether each of the first antenna group (610) and / or the second antenna group (620) satisfies TER conditions. For example, the electronic device (700) can check whether the TER margin exceeds a set value. The TER margin may indicate the difference between the maximum allowable TER of at least one antenna group (e.g., first antenna group (610) and / or second antenna group (620)) (e.g., maximum allowable TER (501) in FIG. 5) and the TER of at least one antenna group (e.g., first antenna group (610) and / or second antenna group (620)) (e.g., TER (510) in FIG. 5). Alternatively, the electronic device (700) may determine whether the maximum power transmission time exceeds the minimum time required for a non-terrestrial network communication connection. The maximum power transmission time may indicate the maximum time during which non-terrestrial network communication can be performed at the maximum power supported by at least one antenna group (first antenna group (610) and / or second antenna group (620)) while the TER of at least one antenna group (first antenna group (610) and / or second antenna group (620)) remains below the maximum allowable TER.

[0092] The TER condition may include a condition in which the TER margin (e.g., the TER margin (512) in FIG. 5) exceeds a set value indicating the TER required for a non-terrestrial network communication connection (e.g., the TER (520) required according to the non-terrestrial network communication connection request in FIG. 5).

[0093] The setting value may be a value indicating the TER required for service through non-terrestrial network communication.

[0094] The setting value may be set based on the non-terrestrial network communication performance of the first antenna group (610) or the second antenna group (620). The non-terrestrial network communication performance may refer to the communication performance in a situation where the first antenna group (610) or the second antenna group (620) communicates with a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2). The non-terrestrial network communication performance may include one or more of the non-terrestrial network maximum transmission power (810), average power limit value (820), transmission time ratio, modulation type, or data transmission speed.

[0095] The setting value may be configured according to the size of the transmitted data included in the non-terrestrial network communication connection request. The non-terrestrial network communication connection request may include a request for data transmission and / or reception based on the non-terrestrial network. The non-terrestrial network-based data may include data necessary to perform services through non-terrestrial network communication. For example, an application may perform a service of transmitting and / or receiving data via non-terrestrial wireless communication. The data may be various types of data, including text messages, video messages, and voice messages.

[0096] The setting value may represent the TER required to transmit transmission data included in a non-terrestrial network communication connection request. The electronic device (700) may determine the setting value based on the TER required per second and the minimum time (840) required for the non-terrestrial network communication connection. For example, the electronic device (700) may determine the setting value based on the value obtained by multiplying the TER required per second and the minimum time (840) required for the non-terrestrial network communication connection. For example, the electronic device (700) may determine the setting value to be greater than the value obtained by multiplying the TER required per second and the minimum time (840) required for the non-terrestrial network communication connection.

[0097] The TER required per second may refer to the TER required per second when the first antenna group (610) or the second antenna group (620) performs non-terrestrial network communication. According to one example, the first antenna group (610) or the second antenna group (620) may transmit data at maximum transmission power (810) when performing non-terrestrial network communication. The TER required per second may refer to the TER required per second while the first antenna group (610) or the second antenna group (620) transmits data at maximum transmission power (810).

[0098] The TER required per second can be set to be proportional to the maximum transmission power (810). The maximum transmission power (810) may refer to the maximum power level that the first antenna group (610) or the second antenna group (620) can transmit when performing non-terrestrial network communication. Based on the maximum transmission power (810), the reach of the signal transmitted by the first antenna group (610) or the second antenna group (620) and / or the quality of the signal may be determined. The maximum transmission power (810) may have units of dBm (decibel-milliwatts).

[0099] The TER required per second can be set to be inversely proportional to the average power limit value (820). The average power limit value (820) may refer to a power limit value based on the time-averaged SAR (or PD), and a wireless signal exposure limit value (e.g., SAR) which is the maximum allowable power value set by a domestic or international regulatory body. limit and / or PD limit It can refer to ).

[0100] The TER required per second can be set to be proportional to the duty rate. The duty rate may refer to the ratio of the time (862) during which an antenna group (e.g., a first antenna group (610) or a second antenna group (620)) transmits a signal during the time (861) allocated for transmission. For example, if the duty rate is 10%, the antenna group (e.g., a first antenna group (610) or a second antenna group (620)) can transmit a signal for 10% of the time allocated for transmission.

[0101] The TER required per second can be set to be inversely proportional to the length of the time window (850). The length of the time window (850) can be determined by a value set by a domestic or international regulatory body.

[0102] The TER required per second according to the example can be set as [Equation 6].

[0103]

[0104] For example, the electronic device (700) can determine the required TER (e.g., 0.018) per second based on the length of the time window (850) (e.g., 100 seconds) and the maximum transmission power (810) (e.g., 36 dBm), average power limit value (820) (e.g., 20 dBm), and transmission time ratio (e.g., 10%) of the non-terrestrial network communication performance of the first antenna group (610) or the second antenna group (620).

[0105] The minimum time (840) required for a non-terrestrial network communication connection may refer to the minimum time required to transmit the transmission data included in the non-terrestrial network communication connection request at the data transmission speed of the antenna group (e.g., the first antenna group (610) or the second antenna group (620)).

[0106] The data transmission speed may refer to the speed at which data is transmitted through the first antenna group (610) or the second antenna group (620). The data transmission speed may have units of bits per second (bps). The data transmission speed may be determined based on at least one of the non-terrestrial network communication performance of the first antenna group (610) or the second antenna group (620). The data transmission speed may be determined according to the modulation and coding scheme (MCS) used by the electronic device (100) when performing non-terrestrial wireless communication. For example, if the modulation type is changed from binary phase shift keying (BPSK) to quadrature phase shift keying (QPSK), the data transmission speed may be doubled.

[0107] For example, the value obtained by dividing the size of the data (e.g., 12 kbytes) by the data transmission speed (e.g., 1.2 kbps) can be determined as the minimum time (840) (e.g., 12 seconds) required for a non-terrestrial network communication connection.

[0108] The electronic device (700) can set a setting value based on the value obtained by multiplying the TER required per second (e.g., 0.018) and the minimum time (840) required for a non-terrestrial network communication connection (e.g., 12 seconds). For example, the electronic device (700) can set a setting value (e.g., 0.220) greater than the value obtained by multiplying the TER required per second (e.g., 0.018) and the minimum time (840) required for a non-terrestrial network communication connection (e.g., 12 seconds) (e.g., 0.216).

[0109] The TER condition may include a condition in which the maximum power transmission time of an antenna group (e.g., a first antenna group (610) or a second antenna group (620)) exceeds (or exceeds) the minimum time (840) for which a non-terrestrial communication connection is required. The maximum power transmission time of an antenna group may refer to the maximum time during which the antenna group can transmit a signal at maximum transmission power while maintaining a TER less than the maximum allowable TER. The electronic device (700) may calculate the maximum power transmission time of an antenna group based on the TER margin of the antenna group and the required TER per second (e.g., the required TER per second of [Equation 6]). For example, the electronic device (700) may determine the maximum power transmission time of an antenna group by dividing the TER margin of the antenna group by the required TER per second (e.g., the required TER per second of [Equation 6]).

[0110] Whether the TER condition is satisfied may be verified based on the elapsed time of the minimum time (840) required for a non-terrestrial network communication connection. The electronic device (700) may calculate a TER margin based on the maximum allowable TER and the TER used during the time window time interval. For example, the electronic device (700) may calculate the difference between the maximum allowable TER and the TER used during the time window time interval as the TER margin. When the electronic device (700) performs a non-terrestrial network communication connection, the time range for calculating the TER used may change as time elapses. For example, if the time window is 100 seconds and the minimum time (840) required for a non-terrestrial network communication connection is 10 seconds, the TER used during the time window time interval at the time the non-terrestrial network communication connection started may represent the TER used during the past 100 seconds from the time the non-terrestrial network communication connection started. However, the TER used during the time window time interval at the point in time when the minimum time (840) required for non-terrestrial network communication connection has elapsed may represent the TER used during the past 100 seconds from the point in time when the minimum time (840) required for non-terrestrial network communication connection has elapsed. Accordingly, the TER used during the past 100 seconds to 90 seconds from the point in time when the non-terrestrial network communication connection started may be a value that is not reflected in the calculation of the TER margin at the point in time when the minimum time (840) required for non-terrestrial network communication connection has elapsed. Accordingly, the electronic device (700) can calculate the TER margin through the TER used during the time window time interval at the point in time when the minimum time (840) required for non-terrestrial network communication connection has elapsed, instead of the TER used during the time window time interval at the point in time when the non-terrestrial network communication connection started.For example, the electronic device (700) can determine the difference value of the previously used TER during the time interval (time window length (e.g., 100 seconds) - minimum time (840) (e.g., 10 seconds) required for non-terrestrial network communication connection) at the time when the maximum allowable TER and the non-terrestrial network communication connection are started as the TER margin.

[0111] Whether the TER condition is satisfied may vary depending on the TER margin. The TER margin may be calculated differently depending on the certain proportion of the reserve margin in the maximum allowable TER. The electronic device (700) may determine the TER margin to a smaller value as the certain proportion of the reserve margin in the maximum allowable TER increases. If the TER margin is determined to be a small value, the electronic device (700) may have to wait until the TER margin satisfies the TER condition. Alternatively, the electronic device (700) may satisfy the TER condition by adjusting the certain proportion of the reserve margin in the maximum allowable TER. The electronic device (700) may determine the TER margin to a larger value as the certain proportion of the reserve margin in the maximum allowable TER decreases. Additionally, as the TER margin increases, the maximum power transmission time may increase. The TER condition may be satisfied when the TER margin determined to be a large value exceeds the set value. Alternatively, the TER condition may be satisfied such that the maximum power transmission time, which increases as the TER margin increases, exceeds the minimum time (840) required for non-terrestrial network communication connection. The electronic device (700) may adjust a certain proportion of the reserve margin within the maximum allowable TER to allow the antenna group to satisfy the TER condition. For example, the maximum power transmission time may be 12.6 seconds when the time window is 100 seconds, the power limit value is 20 dBm, the maximum transmission power is 26 dBm, and the reserve margin is 50%. The maximum power transmission time may increase to 22.6 seconds as the reserve margin decreases to 10%. According to one embodiment, the electronic device (700) may set the certain proportion of the reserve margin within the maximum allowable TER to 0 so that the entire maximum allowable TER can be used.

[0112] FIG. 9 is a flowchart of an operation in which a communication processor according to one embodiment connects non-terrestrial network communication through one of a first antenna group and a second antenna group.

[0113] The electronic device (700) (or, communication processor (712)) may receive a non-terrestrial network communication connection request in operation 910. The non-terrestrial network communication connection request may refer to a request instructing to establish data communication through a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2).

[0114] For example, an application of an electronic device (700) may request an application processor (711) to connect to non-terrestrial network communication based on user input to enable a service via non-terrestrial network communication or the satisfaction of specific conditions under which non-terrestrial network communication is automatically enabled. The application may request the connection to non-terrestrial network communication by transmitting a command (e.g., a command to enable non-terrestrial wireless communication) implemented on a layer other than the application (e.g., a framework) to the application processor (711). The application processor (711) may transmit the request for non-terrestrial network communication connection to a communication processor (712).

[0115] According to one embodiment, the operation 910 of receiving a non-terrestrial network communication connection request may include an operation of confirming that a communication connection using a terrestrial network is not possible. The communication processor (712) may confirm that a terrestrial network communication connection is not possible if it cannot provide a service (e.g., message transmission, call connection) requested by a specific application based on a terrestrial network communication connection. The communication processor (712) may perform the operation described in FIG. 9 by confirming that a terrestrial network communication connection is not possible even without receiving a non-terrestrial network communication connection request from the application processor (711).

[0116] The electronic device (700) (or the communication processor (712)) can scan for connectable non-ground network base stations. For example, the electronic device (700) (or the communication processor (712)) can scan for connectable non-ground network base stations in response to receiving a communication connection request (e.g., a non-ground network communication connection request or a ground network communication connection request) required for a service (e.g., message transmission, call connection) requested by a specific application. For example, the electronic device (700) (or the communication processor (712)) can scan for connectable non-ground network base stations when it is confirmed that a communication connection using a ground network is not possible.

[0117] A non-ground network base station may refer to an entity that provides various forms of non-ground network communication services. For example, a non-ground network base station may be an entity that is not fixed to the ground (e.g., a non-ground wireless communication device (220)). A connectable non-ground network base station may refer to a base station that includes an electronic device (700) within the coverage area where the non-ground network base station can perform wireless communication. The electronic device (700) (or, communication processor (712)) may receive a signal (e.g., a master information block (MIB) and / or a system information block (SIB)) provided by the non-ground network base station and determine whether the electronic device (700) is within the coverage area of ​​the non-ground network base station. The electronic device (700) (or, communication processor (712)) may identify a connectable non-ground network base station having coverage that covers the electronic device (700).

[0118] If the non-ground network base station is in a movable form (e.g., satellite), the non-ground network base station can move continuously. The movement of the non-ground network base station may refer to the electronic device (100) moving out of the coverage of the non-ground network base station. Accordingly, even if the electronic device (or, communication processor (712)) confirms that the electronic device (700) is within the coverage of the non-ground network base station, it may periodically scan the signals provided by the non-ground network base station to reconfirm whether the electronic device (700) is within the coverage of the non-ground network base station. The electronic device (700) (or, communication processor (712)) may perform a cell scan within the non-ground network communication coverage (e.g., non-ground wireless communication coverage (325)) provided by a connectable non-ground network base station (e.g., non-ground wireless communication device (220)). The communication processor (712) can identify cells provided by a connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)) as a result of performing a cell scan. The communication processor (712) can identify multiple cells provided by a connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)). A cell scan may refer to an operation in which an electronic device (700) searches for cells that transmit (or broadcast) signals through a frequency band supported by a communication circuit (e.g., communication circuit (160) of FIG. 1). For example, the electronic device (700) (or the communication processor (712)) can search for cells (or non-terrestrial network base stations) based on various frequency bands and wireless communication technologies (e.g., LTE, 5G, non-terrestrial network). The electronic device (700) can determine information indicating the performance of the cell, including the signal strength of the signal received from the discovered cell (or non-terrestrial network base station) (received signal strength indicator, RSSI), the signal-to-noise ratio (SNR), and / or the cell ID.The electronic device (700) can determine the priority of the discovered cells (or non-ground network base stations) based on information indicating the performance of the cells (or non-ground network base stations). The electronic device (700) (or, communication processor (712)) can determine in operation 920 whether at least one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition.

[0119] The electronic device (700) (or, communication processor (712)) may determine the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) in response to receiving a request for a non-terrestrial network communication connection. The electronic device (700) may determine the TER of each of the first antenna group (610) and the second antenna group (620) based on the power value during the time window of the first antenna group (610) and the second antenna group (620) (e.g., the time window (503) of FIG. 5). The maximum power transmission time may refer to the maximum time during which non-terrestrial network communication can be performed at the maximum power supported by the first antenna group (610) or the second antenna group (620) while the TER of the first antenna group (610) or the second antenna group (620) remains below the maximum allowable TER. For example, the maximum power transmission time can be determined by dividing the TER margin, which represents the difference between the maximum allowable TER (e.g., the maximum allowable TER (501) in FIG. 5) and the TER of the antenna group (e.g., the TER (510) in FIG. 5), by the TER required per second.

[0120] The electronic device (700) (or, communication processor (712)) can determine whether each of the first antenna group (610) and the second antenna group (620) satisfies the TER condition. The TER condition may include a condition in which the TER margin exceeds a set value indicating the TER required for a non-terrestrial network communication connection (e.g., the TER required according to the non-terrestrial network communication connection request of FIG. 5 (520)). The electronic device (700) can calculate the set value according to [Equation 6] described in FIG. 8. The TER condition may include a condition in which the maximum power transmission time of the antenna group (e.g., the first antenna group (610) or the second antenna group (620)) exceeds the minimum time required for a non-terrestrial network communication connection (e.g., the minimum time required for a non-terrestrial network communication connection of FIG. 8 (840)).

[0121] The electronic device (700) (or, communication processor (712)) may repeat the operation 920 until at least one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition if both the first antenna group (610) and the second antenna group (620) do not satisfy the TER condition. For example, if both the first antenna group (610) and the second antenna group (620) do not satisfy the TER condition, the electronic device (700) (or, communication processor (712)) may reconfirm the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) after a specified time has elapsed. The reconfirmed TER may be a value lower than the previously confirmed TER as the specified time has elapsed. For example, the reconfirmed TER may be a value lower than the previously confirmed TER as the proportion of time that is the lowest transmission power mode included in the time window, which is the time interval for calculating the TER, increases. The TER margin, representing the difference between the maximum allowable TER and the reconfirmed TER, may be larger than the previously confirmed TER margin, representing the difference between the maximum allowable TER and the previously confirmed TER, as the reconfirmed TER decreases. The maximum power transmission time, representing the value obtained by dividing the TER margin by the TER required per second, may be a value larger than the previously confirmed maximum power transmission time, as the TER margin increases. The electronic device (700) (or, communication processor (712)) may repeat the operation of waiting for a specified time and the 920 operation until at least one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition.

[0122] The electronic device (700) (or, communication processor (712)) can check in operation 930 whether the first antenna group (610) and the second antenna group (620) satisfy the TER condition when at least one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition.

[0123] The electronic device (700) (or, communication processor (712)) may perform operation 930 to determine which of the first antenna group (610) or the second antenna group (620) is to perform a non-terrestrial network communication connection. The electronic device (700) (or, communication processor (712)) may perform a non-terrestrial network communication connection through either the first antenna group (610) or the second antenna group (620) if both of the first antenna group (610) and the second antenna group (620) satisfy the TER condition. The communication processor (712) may perform a non-terrestrial network communication connection through the antenna group that satisfies the TER condition if one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition and the other of the first antenna group (610) or the second antenna group (620) does not satisfy the TER condition.

[0124] The electronic device (700) (or, communication processor (712)) can connect non-terrestrial network communication through the high-priority antenna group in operation 940 when the first antenna group (610) and the second antenna group (620) satisfy the TER condition.

[0125] The electronic device (700) (or, communication processor (712)) can identify the antenna group with the higher priority between the first antenna group (610) and the second antenna group (620) through a preset priority between the first antenna group (610) and the second antenna group (620). For example, the preset priority between the first antenna group (610) and the second antenna group (620) can be set so that the antenna group (e.g., the first antenna group (610)) placed on the upper part of the housing of the electronic device (700) has a higher priority.

[0126] Alternatively, the electronic device (700) (or the communication processor (712)) may determine the priority of the first antenna group (610) and the second antenna group (620) based on the TER of the first antenna group (610) and / or the second antenna group (620), non-terrestrial network communication performance, and / or placement. Non-terrestrial network communication performance may include an increase in one of the non-terrestrial network maximum transmission power, transmission time ratio, modulation type, or data transmission rate. The electronic device (700) (or the communication processor (712)) may determine the antenna group with more remaining TER, the antenna group with higher maximum transmission power, the antenna group with higher data transmission rate, or the antenna group placed in the upper part of the housing as the antenna group of high priority.

[0127] The electronic device (700) (or, communication processor (712)) can connect non-terrestrial network communication through the antenna group satisfying the TER condition in operation 950 when only one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition.

[0128] The electronic device (700) (or, communication processor (712)) can establish a non-ground network communication connection through a scanned connectable non-ground network base station when performing a non-ground network communication connection in operation 940 or operation 950.

[0129] According to one embodiment, an electronic device (700) (or a communication processor (712)) can perform a communication connection through at least one cell (or non-ground network base station) based on a priority determined based on information indicating the performance of the cell (or non-ground network base station).

[0130] The electronic device (700) of FIG. 9 identifies an antenna group that satisfies TER conditions (e.g., has a TER margin equal to the TER (520) required in response to a request for non-terrestrial network communication connection) and can perform a non-terrestrial network communication connection through the antenna group that satisfies the TER conditions. As the electronic device (700) connects the non-terrestrial network communication through the antenna group that satisfies the TER conditions among a plurality of antenna groups that support non-terrestrial network communication, the wireless signal exposure limit value set by the regulatory authority during the non-terrestrial network communication connection may not be exceeded.

[0131] FIG. 10 is a flowchart of an operation in which a communication processor according to one embodiment connects non-terrestrial network communication through at least one of a first antenna group or a second antenna group.

[0132] The electronic device (700) (or communication processor (712)) may receive a non-terrestrial network communication connection request in operation 1010. The non-terrestrial network communication connection request may refer to a request instructing to establish data communication through a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2).

[0133] For example, an application of an electronic device (700) may request an application processor (711) to connect to non-terrestrial network communication based on user input to enable a service via non-terrestrial network communication or the satisfaction of specific conditions under which non-terrestrial network communication is automatically enabled. The application may request the connection to non-terrestrial network communication by transmitting a command (e.g., a command to enable non-terrestrial wireless communication) implemented on a layer other than the application (e.g., a framework) to the application processor (711). The application processor (711) may transmit the request for non-terrestrial network communication connection to a communication processor (712).

[0134] According to one embodiment, the operation 1010 of receiving a non-terrestrial network communication connection request may include an operation of confirming that a communication connection using a terrestrial network is not possible. The communication processor (712) may confirm that a terrestrial network communication connection is not possible if it cannot provide a service (e.g., message transmission, call connection) requested by a specific application based on a terrestrial network communication connection. The communication processor (712) may perform the operation described in FIG. 10 by confirming that a terrestrial network communication connection is not possible even without receiving a non-terrestrial network communication connection request from the application processor (711).

[0135] The electronic device (700) (or the communication processor (712)) can scan for connectable non-ground network base stations. For example, the electronic device (700) (or the communication processor (712)) can scan for connectable non-ground network base stations in response to receiving a communication connection request (e.g., a non-ground network communication connection request or a ground network communication connection request) required for a service (e.g., message transmission, call connection) requested by a specific application. For example, the electronic device (700) (or the communication processor (712)) can scan for connectable non-ground network base stations when it is confirmed that a communication connection using a ground network is not possible.

[0136] A non-ground network base station may refer to an entity that provides various forms of non-ground network communication services. For example, a non-ground network base station may be an entity that is not fixed to the ground (e.g., a non-ground wireless communication device (220)). A connectable non-ground network base station may refer to a base station that includes an electronic device (700) within the coverage area where the non-ground network base station can perform wireless communication. The electronic device (700) (or, communication processor (712)) may receive a signal (e.g., a master information block (MIB) and / or a system information block (SIB)) provided by the non-ground network base station and determine whether the electronic device (700) is within the coverage area of ​​the non-ground network base station. The electronic device (700) (or, communication processor (712)) may identify a connectable non-ground network base station having coverage that covers the electronic device (700).

[0137] The electronic device (700) (or communication processor (712)) can determine in operation 1020 whether the maximum power transmission time of at least one of the first antenna group (610) or the second antenna group (620) exceeds the time required for non-terrestrial network communication.

[0138] The electronic device (700) (or communication processor (712)) can determine the maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) in response to receiving a request for a non-terrestrial network communication connection. The maximum power transmission time may refer to the maximum time during which non-terrestrial network communication can be performed at the maximum power supported by the first antenna group (610) or the second antenna group (620) while the TER of the first antenna group (610) or the second antenna group (620) remains below the maximum allowable TER. The electronic device (700) can determine the maximum power transmission time based on the maximum allowable TER (e.g., the maximum allowable TER (501) in FIG. 5) and the TER of the antenna group (e.g., the TER (510) in FIG. 5). For example, the maximum power transmission time can be determined by dividing the TER margin, which represents the difference between the maximum allowable TER (e.g., the maximum allowable TER (501) in FIG. 5) and the TER of the antenna group (e.g., the TER (510) in FIG. 5), by the TER required per second.

[0139] The electronic device (700) (or communication processor (712)) can determine in operation 1030 whether the sum of the maximum power transmission times of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication when the maximum power transmission times of the first antenna group (610) and the second antenna group (620) are less than or equal to the time required for non-terrestrial network communication.

[0140] The electronic device (700) (or communication processor (712)) may not be able to perform a non-terrestrial network communication connection using only one of the first antenna group (610) or the second antenna group (620) if the maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) is less than or equal to the time required for non-terrestrial network communication. However, the electronic device (700) (or communication processor (712)) may perform a non-terrestrial network communication connection using both the first antenna group (610) and the second antenna group (620) if the sum of the maximum power transmission times of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication. Using both the first antenna group (610) and the second antenna group (620) may include initiating a non-terrestrial network communication connection using either the first antenna group (610) or the second antenna group (620), and performing antenna switching to the other of the first antenna group (610) or the second antenna group (620). Antenna switching may refer to changing the antenna (group) to another antenna (group) while performing a network communication connection through a specific antenna (group).

[0141] In operation 1060, if the sum of the maximum power transmission times of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication, the electronic device (700) (or communication processor (712)) may establish non-terrestrial network communication through at least one of the first antenna group (610) or the second antenna group (620). For example, the electronic device (700) (or communication processor (712)) may establish non-terrestrial network communication by using both the first antenna group (610) and the second antenna group (620). When the electronic device (700) (or communication processor (712)) uses both the first antenna group (610) and the second antenna group (620), the antenna group with the higher priority may be used first to establish non-terrestrial network communication, but is not limited thereto.

[0142] The electronic device (700) (or communication processor (712)) may perform operation 1020 after a specified time elapsed if the sum of the maximum power transmission times of the first antenna group (610) and the second antenna group (620) is less than or equal to the time required for non-terrestrial network communication.

[0143] The electronic device (700) (or, communication processor (712)) can determine in operation 1040 whether the maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication when the maximum power transmission time of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication.

[0144] The electronic device (700) (or, communication processor (712)) may perform operation 1040 to identify an antenna group for performing a non-terrestrial network communication connection among the first antenna group (610) or the second antenna group (620). The electronic device (700) (or, communication processor (712)) may perform a non-terrestrial network communication connection through either the first antenna group (610) or the second antenna group (620) if the maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication. The electronic device (700) (or, communication processor (712)) can perform a non-terrestrial network communication connection through the antenna group whose maximum power transmission time exceeds the time required for non-terrestrial network communication, provided that the maximum power transmission time of one of the first antenna group (610) or the second antenna group (620) exceeds the time required for non-terrestrial network communication, and the maximum power transmission time of the other of the first antenna group (610) or the second antenna group (620) does not exceed the time required for non-terrestrial network communication.

[0145] The electronic device (700) (or, communication processor (712)) can connect to non-terrestrial network communication through the high-priority antenna group in operation 1050 when the maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication.

[0146] The electronic device (700) (or, communication processor (712)) can identify the antenna group with the higher priority between the first antenna group (610) and the second antenna group (620) through a preset priority between the first antenna group (610) and the second antenna group (620). For example, the preset priority between the first antenna group (610) and the second antenna group (620) can be set so that the antenna group (e.g., the first antenna group (610)) placed on the upper part of the housing of the electronic device (700) has a higher priority.

[0147] Alternatively, the electronic device (700) (or the communication processor (712)) may determine the priority of the first antenna group (610) and the second antenna group (620) based on the TER of the first antenna group (610) and / or the second antenna group (620), non-terrestrial network communication performance, and / or placement. Non-terrestrial network communication performance may include an increase in one of the non-terrestrial network maximum transmission power, transmission time ratio, modulation type, or data transmission rate. The electronic device (700) (or the communication processor (712)) may determine the antenna group with more remaining TER, the antenna group with higher maximum transmission power, the antenna group with higher data transmission rate, or the antenna group placed in the upper part of the housing as the antenna group of high priority.

[0148] In operation 1060, the electronic device (700) (or, communication processor (712)) can establish a non-terrestrial network communication through at least one antenna group, either the first antenna group (610) or the second antenna group (620), when only the maximum power transmission time of one of the antenna groups, either the first antenna group (610) or the second antenna group (620), exceeds the time required for non-terrestrial network communication. For example, the communication processor (712) can establish a non-terrestrial network communication connection through the antenna group where the maximum power transmission time exceeds the time required for non-terrestrial network communication.

[0149] When performing a non-ground network communication connection in operation 1050 or operation 1060, the electronic device (700) (or the communication processor (712)) scans at least one connectable non-ground network base station and can establish a non-ground network communication connection through the connectable non-ground network base station. Alternatively, the communication processor (712) can scan for non-ground network base stations in response to receiving a request for a non-ground network communication connection in operation 1010 and establish a non-ground network communication connection through the connectable non-ground network base station in operation 1050 or operation 1060.

[0150] The electronic device (700) of FIG. 10 can perform a non-terrestrial network communication connection even if the maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) is less than the time required for non-terrestrial network communication, if the sum of the maximum power transmission times of the first antenna group (610) and the second antenna group (620) exceeds the time required for non-terrestrial network communication. The electronic device (700) can perform a non-terrestrial network communication connection while satisfying a wireless signal exposure limit value set by a regulatory authority, depending on whether a specific condition is satisfied, even in a situation where a plurality of antenna groups supporting non-terrestrial network communication do not all satisfy TER conditions (e.g., a condition where the TER margin exceeds a set value indicating the TER required for non-terrestrial network communication connection, or a condition where the maximum power transmission time exceeds the minimum time required for non-terrestrial network communication connection).

[0151] FIG. 11a is an operation flowchart in which an application processor according to one embodiment outputs information indicating that a change in the attitude of an electronic device is required.

[0152] The electronic device (700) (or application processor (711)) can check information indicating an antenna group in operation 1110.

[0153] The electronic device (700) (or the communication processor (712)) may perform a non-terrestrial network communication connection through at least one of the first antenna group (610) or the second antenna group (620) according to the operation of FIG. 9 or FIG. 10. When the antenna group used for the non-terrestrial network communication connection is identified, the communication processor (712) may transmit information indicating the antenna group used for the non-terrestrial network communication connection to the application processor (711). For example, the communication processor (712) may determine that the first antenna group (610) is used for the non-terrestrial network communication connection when the first antenna group (610) satisfies the TER condition and the second antenna group (620) does not satisfy the TER condition. The communication processor (712) may transmit information indicating the first antenna group (610) used for the non-terrestrial network communication connection to the application processor (711). The application processor (711) can identify the antenna group used for non-terrestrial network communication through information indicating the antenna group.

[0154] The electronic device (700) (or, application processor (711)) can determine whether a change in the posture of the electronic device (700) is required in operation 1120.

[0155] The electronic device (700) (or application processor (711)) can determine the attitude of the electronic device (700) through at least one sensor (e.g., an IMU sensor) included in the electronic device (700). The attitude of the electronic device (700) may include the tilt of the electronic device (700). The application processor (711) can determine whether a change in the placement of the electronic device (700) is required based on the antenna group used for non-terrestrial network communication and the attitude of the electronic device (700).

[0156] The electronic device (700) (or application processor (711)) can determine whether the antenna group used for communication connection with the non-terrestrial network base station (e.g., the antenna group that satisfies the TER condition and has a higher priority among the first antenna group or the second antenna group) is positioned to face the non-terrestrial network base station (e.g., the non-terrestrial wireless communication device (220) of FIG. 2). The path loss of the antenna group used for non-terrestrial network communication may vary depending on the degree to which the antenna group used for non-terrestrial network communication is positioned toward the non-terrestrial network base station. For example, the path loss of the antenna group used for non-terrestrial network communication may decrease as the antenna group used for non-terrestrial network communication is positioned toward the non-terrestrial network base station. Positioning the antenna group used for non-terrestrial network communication toward the non-terrestrial network base station may include positioning the direction of the beam of the antenna group used for non-terrestrial network communication toward the non-terrestrial network base station. The beam of an antenna group used for non-terrestrial network communication may refer to a beam generated by a signal output by each of the antennas included in the antenna group. The beam of an antenna group used for non-terrestrial network communication may include various types of beams depending on how much the signal output by which antenna among the antennas included in the antenna group is reflected. The antenna group may establish communication with a non-terrestrial base station using at least one of the various types of beams. The electronic device (700) (or application processor (711)) can check whether the direction of the beam used for communication connection with the non-terrestrial base station is positioned to face the non-terrestrial base station.

[0157] Deploying the antenna group so as to face the non-terrestrial network base station may include positioning the antenna group used for non-terrestrial network communication within an acceptable range of angles where non-terrestrial network communication signals can be reliably transmitted and received. The application processor (711) can determine whether the antenna group used for non-terrestrial network communication is positioned within an acceptable range of angles where non-terrestrial network communication signals can be reliably transmitted and received (e.g., the optimal communication angle range between the satellite and the antenna). The electronic device (700) (or the application processor (711)) can determine that if the antenna group used for non-terrestrial network communication is positioned within an acceptable range of angles where non-terrestrial network communication signals can be reliably transmitted and received, a change in the orientation of the electronic device (700) is not required. Alternatively, the electronic device (700) (or application processor (711)) may determine that a change in the orientation of the electronic device (700) is required if the antenna group used for non-terrestrial network communication is not positioned within an angle of an allowable range in which the non-terrestrial network communication signal can be stably transmitted and received.

[0158] According to one embodiment, an electronic device (700) (or an application processor (711)) can determine the location of a non-ground network base station (e.g., a non-ground wireless communication device (220)) and, based on the determined location of the non-ground network base station, determine whether an antenna group is positioned to face the non-ground network base station. The electronic device (700) (or an application processor (711)) can determine the location of the non-ground network base station and the expected location after a certain time through orbit information of the non-ground network base station, and determine whether an antenna group is positioned to face the determined location. The orbit information of the non-ground network base station may include identification information of the non-ground network base station, information indicating the orbit of the non-ground network base station, and / or information indicating the speed of the non-ground network base station.

[0159] The electronic device (700) (or application processor (711)) can output information indicating that a change in the position of the electronic device (700) is required in operation 1130 when a change in the position of the electronic device (700) is required.

[0160] Information indicating that a change in the posture of the electronic device (700) is required may include information indicating the magnitude and / or direction in which a change in the posture of the electronic device (700) is required. For example, if a rotation of a specific angle in a specific direction is required, the application processor (711) may display on the display information indicating that a change in the posture of the electronic device (700) is required, including information indicating a specific direction and / or information indicating a specific angle.

[0161] The electronic device (700) (or application processor (711)) can monitor the change in the posture of the electronic device (700) after outputting information indicating that a change in the posture of the electronic device (700) is required. The application processor (711) can establish non-terrestrial network communication when a change in the posture of the electronic device (700) is detected that corresponds to information indicating the size and / or direction in which a change in the posture of the electronic device (700) is required, which is included in the information indicating that a change in the posture of the electronic device (700) is required. Additionally, the electronic device (700) (or application processor (711)) may establish non-terrestrial network communication when no change in the posture of the electronic device (700) is detected for a specified period of time.

[0162] The electronic device (700) (or application processor (711)) may output information indicating that the maintenance of the electronic device (700)'s posture is required in operation 1140 when a change in the posture of the electronic device (700) is not required.

[0163] According to one embodiment, the electronic device (700) (or application processor (711)) may omit operation 1140 and connect non-terrestrial network communication when a change in the posture of the electronic device (700) is not required.

[0164] The electronic device (700) of FIG. 11a can determine whether a change in the orientation of the electronic device (700) is required based on whether the antenna group used for the non-terrestrial network communication connection is positioned in the direction of the non-terrestrial network base station when the antenna group used for the non-terrestrial network communication connection is determined. If a change in the orientation of the electronic device (700) is required, the electronic device (700) can guide the electronic device (700) to change its orientation through information indicating that a change in the orientation of the electronic device (700) is required. The path loss of the antenna group used for the non-terrestrial network communication connection can be reduced as the orientation of the electronic device (700) is changed.

[0165] FIG. 11b is a drawing illustrating an electronic device that outputs information indicating that a change in posture is required according to one embodiment.

[0166] The electronic device (700) can determine the attitude of the electronic device (700) through at least one sensor (e.g., a gyroscope sensor) included in the electronic device (700). The attitude of the electronic device (700) may include the tilt (or direction) of the electronic device (700).

[0167] The electronic device (700) can determine whether the electronic device (700) is in a forward or reverse orientation based on the orientation of the electronic device (700). The forward orientation (1151) of the electronic device (700) may refer to an orientation in which the upper part of the housing of the electronic device (700) faces a specific direction (e.g., opposite direction of the ground surface). The reverse orientation (1152) of the electronic device (700) may refer to an orientation in which the lower part of the housing of the electronic device (700) faces a specific direction (e.g., opposite direction of the ground surface). An orientation facing a specific direction may include an orientation within a defined angle range with respect to the specific direction. The electronic device (700) may store information in memory indicating the tilt corresponding to the forward direction and the tilt corresponding to the reverse direction. The electronic device (700) can determine whether the confirmed orientation of the electronic device (700) is in the forward direction or the reverse direction based on information indicating the inclination corresponding to the forward direction and the inclination corresponding to the reverse direction stored in memory.

[0168] The electronic device (700) can identify information indicating an antenna group used for non-terrestrial network communication connection among the first antenna group (610) or the second antenna group (620). An antenna group used for non-terrestrial network communication connection may refer to an antenna group that satisfies TER conditions and has a high priority. The electronic device (700) can determine the priority of the first antenna group (610) and the second antenna group (620) based on the non-terrestrial network communication performance and / or placement of the first antenna group (610) and / or the second antenna group (620).

[0169] The electronic device (700) can determine whether a change in the orientation of the electronic device (700) is required based on the antenna group used for non-terrestrial network communication connection and the orientation of the electronic device (700). An antenna group (e.g., a first antenna group (610)) placed on the upper part of the housing of the electronic device (700) may be positioned at an angle within an allowable range such that non-terrestrial network communication signals can be stably transmitted and received or directed toward a non-terrestrial network base station when the orientation of the electronic device (700) is in a forward orientation (1151). The path loss of the antenna group (e.g., a first antenna group (610)) placed on the upper part of the housing of the electronic device (700) may be lower in the forward orientation (1151) of the electronic device (700) than in the reverse orientation (1152) of the electronic device (700). An antenna group (e.g., a second antenna group (620)) positioned in the lower part of the housing of the electronic device (700) may be positioned at an angle within an allowable range such that non-ground network base stations or non-ground network communication signals can be reliably transmitted and received when the orientation of the electronic device (700) is in a reverse orientation (1152). The path loss of the antenna group (e.g., a second antenna group (620)) positioned in the lower part of the housing of the electronic device (700) may be lower in the reverse orientation (1152) of the electronic device (700) than in the forward orientation (1151) of the electronic device (700). The electronic device (700) can confirm that a change in the orientation of the electronic device (700) is required when the antenna group used for non-terrestrial network communication connection is an antenna group (e.g., a first antenna group (610)) placed in the upper part of the housing of the electronic device (700) and the orientation of the electronic device (700) is not a forward orientation (1151) (e.g., a reverse orientation (1152)).Alternatively, the electronic device (700) can confirm that a change in the orientation of the electronic device (700) is required when the antenna group used for non-terrestrial network communication connection is an antenna group (e.g., a second antenna group (620)) placed in the lower part of the housing of the electronic device (700) and the orientation of the electronic device (700) is not a forward orientation (1151) (e.g., a reverse orientation (1152)).

[0170] When it is confirmed that a change in the posture of the electronic device (700) is required, the electronic device (700) may output information (1102) indicating that a change in the posture of the electronic device (700) is required. The electronic device (700) may output information (1102) indicating that a change in the posture of the electronic device (700) is required on a display (1101) included in the electronic device (700) (e.g., the display (1101) (140) of FIG. 1). The information (1102) indicating that a change in the posture of the electronic device (700) is required may include information instructing the electronic device (700) to have a forward or reverse posture (1152). For example, when a transition between the forward and reverse directions is required, the electronic device (700) may output information requesting a transition between the forward and reverse directions (e.g., please turn the mobile phone down (or up)).

[0171] The electronic device (700) can change the direction in which information (1102) indicating that a change in the posture of the electronic device (700) is required is displayed according to the posture of the electronic device (700). For example, when the posture of the electronic device (700) is in a reverse posture (1152), the direction in which information (1103) indicating that a change in the posture of the electronic device (700) is required is displayed may be opposite to the direction in which information (1102) indicating that a change in the posture of the electronic device (700) is required is displayed when the posture of the electronic device (700) is in a forward posture (1151) (e.g., a direction rotated 180 degrees). The user of the electronic device (700) can easily confirm the information (1103) indicating that a change in the posture of the electronic device (700) is required, even if the electronic device (700) is in a reverse posture (1152), because the direction in which the information (1103) indicating that a change in the posture of the electronic device (700) is required is opposite to the direction in which it is displayed when it is in a forward direction.

[0172] FIG. 12 is a flowchart of an operation in which a communication processor determines an antenna group used for non-terrestrial network communication connection among a first antenna group or a second antenna group, according to one embodiment.

[0173] The electronic device (700) (or, communication processor (712)) can check information indicating the attitude of the electronic device (700) in operation 1210.

[0174] An electronic device (700) (or an application processor (711)) can determine the attitude of the electronic device (700) through at least one sensor (e.g., an IMU sensor) included in the electronic device (700). The application processor (711) can transmit information indicating the attitude of the confirmed electronic device (700) to a communication processor (712), and the communication processor (712) can determine the attitude of the electronic device (700) through the received information indicating the attitude of the electronic device (700).

[0175] The electronic device (700) (or, communication processor (712)) can check in operation 1220 whether the first antenna group (610) and the second antenna group (620) satisfy the TER condition. The description of operations 920 and 930 of FIG. 9 may be applied to operation 1220. For example, the electronic device (700) (or, communication processor (712)) can check the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) in response to the reception of a non-terrestrial network communication connection request. The electronic device (700) (or, communication processor (712)) can check whether each of the first antenna group (610) and the second antenna group (620) satisfies the TER condition.

[0176] The electronic device (700) (or, communication processor (712)) can establish non-terrestrial network communication through the antenna group in the direction of the non-terrestrial network base station, based on information indicating the attitude of the electronic device (700), in operation 1230, when the first antenna group (610) and the second antenna group (620) satisfy the TER condition.

[0177] The electronic device (700) (or, communication processor (712)) can establish non-terrestrial network communication through either the first antenna group (610) or the second antenna group (620) when both the first antenna group (610) and the second antenna group (620) satisfy the TER condition. The electronic device (700) (or, communication processor (712)) can determine the angle between each of the first antenna group (610) and the second antenna group (620) and the non-terrestrial network base station through information indicating the attitude of the electronic device (700). The electronic device (700) (or, communication processor (712)) can determine the antenna group positioned toward the non-terrestrial network base station among the first antenna group (610) and the second antenna group (620) through the angle between each of the first antenna group (610) and the second antenna group (620) and the non-terrestrial network base station. An electronic device (700) (or a communication processor (712)) can connect non-ground network communication through an antenna group positioned toward a non-ground network base station among the first antenna group (610) or the second antenna group (620). An antenna group positioned toward a non-ground network base station may refer to an antenna group positioned toward a non-ground network base station to a greater degree among the first antenna group (610) or the second antenna group (620). For example, if the angle between the first antenna group (610) and the non-ground network base station is 10 degrees and the angle between the second antenna group (620) and the non-ground network base station is 170 degrees, the electronic device (700) (or a communication processor (712)) can connect non-ground network communication through the first antenna group (610), which has a smaller angle with the non-ground network base station.

[0178] The electronic device (700) (or, communication processor (712)) can connect non-terrestrial network communication through the antenna group satisfying the TER condition in operation 1240 when only one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition.

[0179] The electronic device (700) (or, communication processor (712)) may reconfirm the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) after a specified time elapsed, if both the first antenna group (610) and the second antenna group (620) do not satisfy the TER condition. The electronic device (700) (or, communication processor (712)) may perform operation 1240 if, based on the reconfirmed TER or maximum power transmission time, either the first antenna group (610) or the second antenna group (620) satisfies the TER condition. The electronic device (700) (or, communication processor (712)) may repeat the operation of reconfirming the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) after a specified time elapsed until one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition, and the operation of confirming whether one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition based on the reconfirmed TER or maximum power transmission time.

[0180] The electronic device (700) of FIG. 12 can perform a non-terrestrial network communication connection through an antenna group facing the direction of a non-terrestrial network base station (e.g., the non-terrestrial wireless communication device (220) of FIG. 2) when both the first antenna group (610) and the second antenna group (620) satisfy the TER condition. By performing a non-terrestrial network communication connection through an antenna group facing the direction of a non-terrestrial network base station, the electronic device (700) can reduce path loss during the non-terrestrial network communication connection.

[0181] FIGS. 13a and FIGS. 13b are flowcharts of an operation in which a processor determines the antenna group used for non-terrestrial network communication connection among the first antenna group or the second antenna group, and outputs information indicating that a change in the attitude of the electronic device is required.

[0182] The operation of the electronic device (700) (or processor (710)) of FIGS. 13a and 13b may be an operation performed by one of at least one processor included in the electronic device (700) (e.g., application processor (711), communication processor (712) of FIG. 7).

[0183] The electronic device (700) (or, processor (710) (e.g., communication processor (712))) can check information indicating the attitude of the electronic device (700) in operation 1310.

[0184] An electronic device (700) (or an application processor (711)) can determine the attitude of the electronic device (700) through at least one sensor (e.g., an IMU sensor) included in the electronic device (700). The application processor (711) can transmit information indicating the attitude of the confirmed electronic device (700) to a communication processor (712), and the communication processor (712) can determine the attitude of the electronic device (700) through the received information indicating the attitude of the electronic device (700).

[0185] The electronic device (700) (or, processor (710) (e.g., communication processor (712))) can check in operation 1320 whether the first antenna group (610) and the second antenna group (620) satisfy the TER condition. The description of operations 920 and 930 of FIG. 9 may be applied to operation 1320. For example, the electronic device (700) (or, communication processor (712)) can check the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) in response to the reception of a non-terrestrial network communication connection request. The electronic device (700) (or, communication processor (712)) can check whether each of the first antenna group (610) and the second antenna group (620) satisfies the TER condition.

[0186] The electronic device (700) (or, processor (710) (e.g., communication processor (712))) can identify the antenna group in the direction of the non-ground network base station based on information indicating the attitude of the electronic device (700) in operation 1330 when the first antenna group (610) and the second antenna group (620) satisfy the TER condition.

[0187] The electronic device (700) (or, communication processor (712)) can establish non-terrestrial network communication through either the first antenna group (610) or the second antenna group (620) when both the first antenna group (610) and the second antenna group (620) satisfy the TER condition. The electronic device (700) (or, communication processor (712)) can determine the angle between each of the first antenna group (610) and the second antenna group (620) and the non-terrestrial network base station through information indicating the attitude of the electronic device (700). The electronic device (700) (or, communication processor (712)) can determine the antenna group positioned toward the non-terrestrial network base station among the first antenna group (610) and the second antenna group (620) through the angle between each of the first antenna group (610) and the second antenna group (620) and the non-terrestrial network base station. An electronic device (700) (or a communication processor (712)) can connect non-ground network communication through an antenna group positioned toward a non-ground network base station among the first antenna group (610) or the second antenna group (620). An antenna group positioned toward a non-ground network base station may refer to an antenna group positioned toward a non-ground network base station to a greater degree among the first antenna group (610) or the second antenna group (620). For example, if the angle between the first antenna group (610) and the non-ground network base station is 10 degrees and the angle between the second antenna group (620) and the non-ground network base station is 170 degrees, the electronic device (700) (or a communication processor (712)) can connect non-ground network communication through the first antenna group (610), which has a smaller angle with the non-ground network base station.

[0188] The electronic device (700) (or, processor (710) (e.g., communication processor (712))) can identify an antenna group that satisfies the TER condition in operation 1340 when the first antenna group (610) and the second antenna group (620) do not satisfy the TER condition.

[0189] The electronic device (700) (or, communication processor (712)) may reconfirm the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) after a specified time has elapsed, if both the first antenna group (610) and the second antenna group (620) do not satisfy the TER condition. The electronic device (700) (or, communication processor (712)) may determine whether one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition based on the reconfirmed TER or maximum power transmission time. The electronic device (700) (or, communication processor (712)) may repeat the operation of reconfirming the TER or maximum power transmission time of each of the first antenna group (610) and the second antenna group (620) after a specified time elapsed until one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition, and the operation of confirming whether one of the first antenna group (610) or the second antenna group (620) satisfies the TER condition based on the reconfirmed TER or maximum power transmission time.

[0190] The electronic device (700) (or, processor (710) (e.g., application processor (711))) can check information indicating the identified antenna group in operation 1350.

[0191] When an antenna group used for a non-terrestrial network communication connection is identified, the electronic device (700) (or the communication processor (712)) can transmit information indicating the antenna group used for a non-terrestrial network communication connection to the application processor (711). The electronic device (700) (or the application processor (711)) can identify the antenna group used for a non-terrestrial network communication through the information indicating the antenna group.

[0192] The electronic device (700) (or, processor (710) (e.g., application processor (711))) can determine whether a change in the posture of the electronic device (700) is required in operation 1360.

[0193] The electronic device (700) (or application processor (711)) can determine the attitude of the electronic device (700) through at least one sensor (e.g., an IMU sensor) included in the electronic device (700). The attitude of the electronic device (700) may include the tilt of the electronic device (700). The electronic device (700) (or application processor (711)) can determine whether a change in the placement of the electronic device (700) is required based on the antenna group used for non-terrestrial network communication and the attitude of the electronic device (700).

[0194] The electronic device (700) (or application processor (711)) can determine whether the antenna group used for communication connection with the non-ground network base station is positioned to face the non-ground network base station. Positioning the antenna group to face the non-ground network base station may include positioning the antenna group used for non-ground network communication within an acceptable range of angles where the non-ground network communication signal can be stably transmitted and received. The electronic device (700) (or application processor (711)) can determine whether the antenna group used for non-ground network communication is positioned within an acceptable range of angles where the non-ground network communication signal can be stably transmitted and received (e.g., the optimal communication angle range between the satellite and the antenna). The electronic device (700) (or application processor (711)) can determine that if the antenna group used for non-ground network communication is positioned within an acceptable range of angles where the non-ground network communication signal can be stably transmitted and received, a change in the orientation of the electronic device (700) is not required. Alternatively, the electronic device (700) (or application processor (711)) may determine that a change in the orientation of the electronic device (700) is required if the antenna group used for non-terrestrial network communication is not positioned within an angle of an allowable range in which the non-terrestrial network communication signal can be stably transmitted and received.

[0195] The electronic device (700) (or, processor (710) (e.g., application processor (711))) can output information indicating that a change in the position of the electronic device (700) is required in operation 1370 when a change in the position of the electronic device (700) is required.

[0196] Information indicating that a change in the posture of the electronic device (700) is required may include information indicating the magnitude and / or direction in which a change in the posture of the electronic device (700) is required. For example, if a rotation of a specific angle in a specific direction is required, the application processor (711) may display on the display information indicating that a change in the posture of the electronic device (700) is required, including information indicating a specific direction and / or information indicating a specific angle.

[0197] The electronic device (700) (or application processor (711)) can monitor the change in the posture of the electronic device (700) after outputting information indicating that a change in the posture of the electronic device (700) is required. The electronic device (700) (or application processor (711)) can establish non-terrestrial network communication when a change in the posture of the electronic device (700) is detected that corresponds to information indicating the size and / or direction in which a change in the posture of the electronic device (700) is required, which is included in the information indicating that a change in the posture of the electronic device (700) is required. Additionally, the electronic device (700) (or application processor (711)) may establish non-terrestrial network communication when no change in the posture of the electronic device (700) is detected for a specified period of time.

[0198] The electronic device (700) (or, processor (710) (e.g., application processor (711))) may output information indicating that the maintenance of the electronic device (700)'s posture is required in operation 1380 when a change in the electronic device (700)'s posture is not required.

[0199] According to one embodiment, the electronic device (700) (or application processor (711)) may omit operation 1380 and connect non-terrestrial network communication when a change in the posture of the electronic device (700) is not required.

[0200] The electronic device (700) of FIGS. 13a and 13b can perform a non-terrestrial network communication connection through an antenna group facing the direction of a non-terrestrial network base station (e.g., the non-terrestrial wireless communication device (220) of FIG. 2) when both the first antenna group (610) and the second antenna group (620) satisfy the TER condition. By performing a non-terrestrial network communication connection through an antenna group facing the direction of the non-terrestrial network base station, the electronic device (700) can reduce path loss during the non-terrestrial network communication connection. Additionally, when the antenna group used for the non-terrestrial network communication connection is determined, the electronic device can determine whether a change in the orientation of the electronic device (700) is required based on whether the antenna group used for the non-terrestrial network communication connection is positioned in the direction of the non-terrestrial network base station. When a change in the attitude of the electronic device (700) is required, the electronic device (700) can be guided to change the attitude of the electronic device (700) through information indicating that a change in the attitude of the electronic device (700) is required. The path loss of the antenna group used for non-terrestrial network communication connection can be reduced as the attitude of the electronic device (700) is changed.

[0201] FIGS. 14a and FIGS. 14b are operation flowcharts for determining which antenna is used when connecting to a non-terrestrial network among the first antenna or the second antenna of a processor, and outputting information indicating that a change in the attitude of the electronic device is required.

[0202] The operation of the electronic device (700) (or processor (710)) of FIG. 14a and FIG. 14b may be an operation performed by one of at least one processor included in the electronic device (700) (e.g., application processor (711), communication processor (712) of FIG. 7).

[0203] In FIG. 14a and FIG. 14b, two antenna groups are described, but the electronic device (700) can perform the operation of FIG. 14a and FIG. 14b for three or more antennas included in the electronic device (700).

[0204] The electronic device (700) (or, communication processor (712)) can check information indicating the attitude of the electronic device (700) in operation 1410.

[0205] An electronic device (700) (or an application processor (711)) can determine the attitude of the electronic device (700) through at least one sensor (e.g., an IMU sensor) included in the electronic device (700). The application processor (711) can transmit information indicating the attitude of the confirmed electronic device (700) to a communication processor (712), and the communication processor (712) can determine the attitude of the electronic device (700) through the received information indicating the attitude of the electronic device (700).

[0206] The electronic device (700) (or communication processor (712)) can check whether the first antenna and the second antenna satisfy predetermined conditions in operation 1420.

[0207] The predetermined conditions may include TER conditions and / or signal quality conditions. The signal quality conditions may include conditions in which an indicator of signal quality (e.g., at least one of reference signal received power (RSRP), max transmit power limit (MTPL), signal to interference plus noise ratio (SINR), reference signal received quality (RSRQ), channel quality indicator (CQI), or path loss) is greater than or less than a threshold value set for each indicator of signal quality.

[0208] The first antenna and the second antenna may be antennas included in the same antenna group (e.g., one of the first antenna group (610) or the second antenna group (620)) or different antenna groups (e.g., the first antenna group (610) and the second antenna group (620)).

[0209] The electronic device (700) (or communication processor (712)) can identify the antenna in the direction of the non-ground network base station based on information indicating the attitude of the electronic device (700) in operation 1430 when the first antenna and the second antenna satisfy predetermined conditions.

[0210] The electronic device (700) (or, communication processor (712)) can establish non-terrestrial network communication through either the first antenna or the second antenna when both the first antenna and the second antenna satisfy predetermined conditions. The electronic device (700) (or, communication processor (712)) can determine the angle between each of the first antenna and the second antenna and the non-terrestrial network base station through information indicating the attitude of the electronic device (700). The electronic device (700) (or, communication processor (712)) can determine which of the first antenna or the second antenna is positioned toward the non-terrestrial network base station through the angle between each of the first antenna and the second antenna and the non-terrestrial network base station. The electronic device (700) (or, communication processor (712)) can establish non-terrestrial network communication through the antenna positioned toward the non-terrestrial network base station among the first antenna or the second antenna. An antenna positioned in the direction of a non-ground network base station may refer to the antenna that is positioned more in the direction of the non-ground network base station among the first antenna and the second antenna. For example, if the angle between the first antenna and the non-ground network base station is 10 degrees and the angle between the second antenna and the non-ground network base station is 170 degrees, the electronic device (700) (or communication processor (712)) can establish non-ground network communication through the first antenna, which has a smaller angle with the non-ground network base station.

[0211] The electronic device (700) (or, processor (710) (e.g., communication processor (712))) can identify an antenna that satisfies a predetermined condition in operation 1440 when the first antenna and the second antenna do not satisfy a predetermined condition.

[0212] For example, if both the first antenna and the second antenna do not satisfy the TER condition, the electronic device (700) (or the communication processor (712)) may reconfirm the TER or maximum power transmission time of each of the first antenna and the second antenna after a specified time has elapsed. The electronic device (700) (or the communication processor (712)) may check whether one of the first antenna or the second antenna satisfies the TER condition based on the reconfirmed TER or maximum power transmission time. The electronic device (700) (or the communication processor (712)) may repeat the operation of reconfirming the TER or maximum power transmission time of each of the first antenna and the second antenna after a specified time has elapsed and the operation of checking whether one of the first antenna or the second antenna satisfies the TER condition based on the reconfirmed TER or maximum power transmission time until one of the first antenna or the second antenna satisfies the TER condition.

[0213] For example, if the first antenna and the second antenna do not satisfy the signal quality conditions, the electronic device (700) (or the communication processor (712)) may reconfirm the indicators representing the signal quality of each of the first antenna and the second antenna after a specified time has elapsed. The electronic device (700) (or the communication processor (712)) may repeat the operation of reconfirming the indicators representing the signal quality of each of the first antenna and the second antenna after a specified time has elapsed until one of the first antenna or the second antenna satisfies the signal quality conditions, and the operation of checking whether one of the first antenna or the second antenna satisfies the signal quality conditions based on the reconfirmed indicators representing the signal quality.

[0214] The electronic device (700) (or, processor (710) (e.g., application processor (711))) can check information indicating the identified antenna in operation 1450.

[0215] The electronic device (700) (or, communication processor (712)) can transmit information indicating the antenna used for the non-terrestrial network communication connection to the application processor (711) when the antenna used for the non-terrestrial network communication connection is identified. The electronic device (700) (or, application processor (711)) can identify the antenna used for the non-terrestrial network communication through the information indicating the antenna.

[0216] The electronic device (700) (or, processor (710) (e.g., application processor (711))) can determine whether a change in the posture of the electronic device (700) is required in operation 1460.

[0217] The electronic device (700) (or application processor (711)) can determine the attitude of the electronic device (700) through at least one sensor (e.g., an IMU sensor) included in the electronic device (700). The attitude of the electronic device (700) may include the tilt of the electronic device (700). The electronic device (700) (or application processor (711)) can determine whether a change in the placement of the electronic device (700) is required based on the attitude of the electronic device (700) and the antenna used for non-terrestrial network communication.

[0218] The electronic device (700) (or application processor (711)) can determine whether the antenna used for communication connection with the non-ground network base station is positioned to face the non-ground network base station. Positioning the antenna to face the non-ground network base station may include positioning the antenna used for non-ground network communication within an acceptable range of angles where the non-ground network communication signal can be stably transmitted and received. The electronic device (700) (or application processor (711)) can determine whether the antenna used for non-ground network communication is positioned within an acceptable range of angles where the non-ground network communication signal can be stably transmitted and received (e.g., the optimal communication angle range between the satellite and the antenna). The electronic device (700) (or application processor (711)) can determine that if the antenna used for non-ground network communication is positioned within an acceptable range of angles where the non-ground network communication signal can be stably transmitted and received, a change in the orientation of the electronic device (700) is not required. Alternatively, the electronic device (700) (or the application processor (711)) may determine that a change in the orientation of the electronic device (700) is required if the antenna used for non-terrestrial network communication is not positioned within an angle of an allowable range in which the non-terrestrial network communication signal can be stably transmitted and received.

[0219] The electronic device (700) (or, processor (710) (e.g., application processor (711))) can output information indicating that a change in the position of the electronic device (700) is required in operation 1370 when a change in the position of the electronic device (700) is required.

[0220] Information indicating that a change in the posture of the electronic device (700) is required may include information indicating the magnitude and / or direction in which a change in the posture of the electronic device (700) is required. For example, if a rotation of a specific angle in a specific direction is required, the application processor (711) may display on the display information indicating that a change in the posture of the electronic device (700) is required, including information indicating a specific direction and / or information indicating a specific angle.

[0221] The electronic device (700) (or application processor (711)) can monitor the change in the posture of the electronic device (700) after outputting information indicating that a change in the posture of the electronic device (700) is required. The electronic device (700) (or application processor (711)) can establish non-terrestrial network communication when a change in the posture of the electronic device (700) is detected that corresponds to information indicating the size and / or direction in which a change in the posture of the electronic device (700) is required, which is included in the information indicating that a change in the posture of the electronic device (700) is required. Additionally, the electronic device (700) (or application processor (711)) may establish non-terrestrial network communication when no change in the posture of the electronic device (700) is detected for a specified period of time.

[0222] The electronic device (700) (or, processor (710) (e.g., application processor (711))) may output information indicating that the maintenance of the electronic device (700)'s posture is required in operation 1380 when a change in the electronic device (700)'s posture is not required.

[0223] According to one embodiment, the electronic device (700) (or application processor (711)) may omit operation 1380 and connect non-terrestrial network communication when a change in the posture of the electronic device (700) is not required.

[0224] The electronic device (700) of FIGS. 14a and FIGS. 14b can perform a non-terrestrial network communication connection through an antenna facing the direction of a non-terrestrial network base station (e.g., the non-terrestrial wireless communication device (220) of FIG. 2) when both the first antenna and the second antenna satisfy predetermined conditions. By performing a non-terrestrial network communication connection through an antenna facing the direction of the non-terrestrial network base station, the electronic device (700) can reduce path loss of the non-terrestrial network communication. Additionally, when the antenna used for the non-terrestrial network communication connection is determined, the electronic device can determine whether a change in the orientation of the electronic device (700) is required based on whether the antenna used for the non-terrestrial network communication connection is positioned in the direction of the non-terrestrial network base station. If a change in the orientation of the electronic device (700) is required, the electronic device (700) can guide the electronic device (700) to change its orientation through information indicating that a change in the orientation of the electronic device (700) is required. The path loss of the antenna used for non-terrestrial network communication connection can be reduced as the orientation of the electronic device (700) changes.

[0225] FIG. 15 is a flowchart of an operation in which a communication processor according to one embodiment uses a preset antenna group in response to confirming a non-terrestrial network communication connection.

[0226] According to one embodiment, a first antenna group (610) disposed in the upper portion of the housing of an electronic device (600) may be an antenna group configured to be used when connecting to a non-terrestrial network communication. The electronic device (600) may use the first antenna group (610) when it confirms that it is connected to a non-terrestrial network communication after connecting to a network communication. For example, when the electronic device (600) is connected to a non-terrestrial network communication through a second antenna group (620), it may perform antenna switching from the second antenna group (620) to the first antenna group (610). However, the location where the first antenna group (610) and / or the second antenna group (620) are disposed may vary and is not limited to the above example.

[0227] An electronic device (700) (or a communication processor (712)) can establish network communication in operation 1510. The operation of establishing network communication may include establishing a new communication with a network while not connected to a network and / or performing a handover to another network while using a specific network.

[0228] According to one embodiment, the network connected by the communication processor (712) may be a network in which a non-ground network and a ground network coexist. While the electronic device (700) is using the network in which a non-ground network and a ground network coexist, a network switching between the non-ground network and the ground network may occur. For example, a network switching from a ground network to a non-ground network may occur. When a network switching occurs from a ground network to a non-ground network, the communication processor (712) may use the antenna group that was used for ground network communication for non-ground network communication.

[0229] The electronic device (700) (or, communication processor (712)) can check whether it is connected to non-terrestrial network communication in operation 1520.

[0230] The electronic device (700) (or, communication processor (712)) can detect the network switching between the non-ground network and the ground network after the network switching between the non-ground network and the ground network has occurred.

[0231] When the electronic device (700) (or communication processor (712)) is connected to a non-terrestrial network communication, in operation 1530, it may use an antenna group that is pre-configured for use when connecting to a non-terrestrial network communication.

[0232] An antenna group used for terrestrial network communication may experience significant path loss when used for non-terrestrial network communication. For example, an antenna group used for terrestrial network communication (e.g., a second antenna group (620) placed in the lower part of the housing of the electronic device (700)) may be an antenna group that is not positioned in the direction of a non-terrestrial network base station. An antenna group that is not positioned in the direction of a non-terrestrial network base station may experience significant path loss when connecting to a non-terrestrial network communication. Therefore, when the electronic device (700) (or the communication processor (712)) confirms that it is connected to a non-terrestrial network communication, it may use an antenna group that is pre-configured for use when connecting to a non-terrestrial network communication. If the antenna group used for terrestrial network communication is not an antenna group pre-configured for use when connecting to a non-terrestrial network communication, the electronic device (700) (or the communication processor (712)) may perform antenna switching to the pre-configured antenna group.

[0233] The electronic device (700) (or communication processor (712)) may use an antenna group pre-configured for use when connecting to a terrestrial network in operation 1540 when not connected to a non-terrestrial network communication.

[0234] According to one embodiment, the electronic device may include a display. The electronic device may include a communication circuit that supports non-terrestrial wireless communication. The electronic device may include a first antenna group. The electronic device may include a second antenna group. The electronic device may include a memory that stores at least one computer program including instructions. The electronic device may include at least one processor. When the at least one computer program is executed individually or collectively by the at least one processor, the electronic device may check the total exposure ratio (TER) or maximum power transmission time of each of the first antenna group and the second antenna group in response to the reception of a non-terrestrial network communication connection request. The at least one computer program may allow the electronic device to check whether each of the first antenna group and the second antenna group satisfies a TER condition for maintaining a TER below the maximum allowable TER, based on the TER or maximum power transmission time of each of the first antenna group and the second antenna group.

[0235] In an electronic device according to one embodiment, the at least one computer program, when executed individually or collectively by the at least one processor, may enable the electronic device to determine whether a change in the arrangement of the electronic device is required based on the position where the antenna group having a higher priority among the first antenna group or the second antenna group satisfies the TER condition and the attitude of the electronic device.

[0238] In an electronic device according to one embodiment, when the at least one computer program is executed individually or collectively by the at least one processor, the electronic device may determine the TER margin based on the difference between the maximum allowable TER and the TER of the antenna group.

[0240] In an electronic device according to one embodiment, when the at least one computer program is executed individually or collectively by the at least one processor, the electronic device may set the setting value based on the size of the transmission data included in the non-terrestrial network communication connection request.

[0241] In an electronic device according to one embodiment, when the computer program is executed individually or collectively by the at least one processor, the electronic device may check whether the sum of the maximum power transmission time of the first antenna group and the maximum power transmission time of the second antenna group exceeds the minimum time required for the non-terrestrial network communication connection when the first antenna group and the second antenna group do not satisfy the TER condition. The at least one computer program may cause the electronic device to establish a non-terrestrial network communication connection through one of the first antenna group or the second antenna group when the sum of the maximum power transmission time of the first antenna group and the maximum power transmission time of the second antenna group exceeds the minimum time required for the non-terrestrial network communication connection. The at least one computer program may cause the other antenna group among the first antenna group or the second antenna group to perform the non-terrestrial network communication in the one antenna group before the maximum power transmission time of the one antenna group has elapsed.

[0242] In an electronic device according to one embodiment, the at least one computer program may enable the electronic device to confirm that it is connected to a non-terrestrial network communication when executed individually or collectively by the at least one processor. The at least one computer program may enable the electronic device to use an antenna group that is preset to be used when connecting to a non-terrestrial network communication among the first antenna group or the second antenna group.

[0243] In an electronic device according to one embodiment, when the at least one computer program is executed individually or collectively by the at least one processor, the electronic device may be configured to check the TER or maximum power transmission possible time of each of the first antenna group and the second antenna group at preset time intervals.

[0244] In an electronic device according to one embodiment, when the at least one computer program is executed individually or collectively by the at least one processor, the electronic device may determine the priority of the first antenna group and the second antenna group based on the non-terrestrial communication performance of the first antenna group and / or the second antenna group and / or the location where the first antenna group and / or the second antenna group are deployed.

[0247] According to one embodiment, the operation of determining whether a change in the arrangement of the electronic device is required may include the operation of determining whether the antenna group having a higher priority among the first antenna group or the second antenna group, which satisfies the TER condition, is arranged to face the non-terrestrial network base station.
