Description

Method for determining the transmission power of an antenna based on an electronic device and the degree of folding of the electronic device

[0001] The present disclosure relates to an electronic device and a method of operating the electronic device, and to a technique for determining the transmission power of an antenna according to the degree of folding of the electronic device and the electronic device.

[0002] Electronic devices may be required to comply with regulations regarding the Specific Absorption Rate (SAR) (unit: W / kg (watts per kilogram)), which represents the energy absorption by human tissue per unit mass. For example, electronic devices may be required to limit transmission power to comply with SAR-related regulations. SAR-related regulations may include criteria where the SAR value measured during a defined time interval, known as a SAR window, is less than the maximum allowable SAR value. The maximum allowable SAR value may refer to a value set by domestic or international regulatory bodies. Electronic devices may comply with SAR-related regulations even if the SAR value during a specific instantaneous SAR window exceeds the maximum allowable SAR value. Domestic or international regulatory bodies recognize compliance with SAR-related regulations if the time-averaged SAR (TAS) value during the SAR measurement cycle does not exceed the maximum allowable SAR value. The TAS value may refer to the average value of the electronic device's SAR values ​​during the SAR measurement cycle. The SAR measurement cycle may refer to the time interval for calculating the time-averaged SAR value as prescribed by domestic or international regulatory agencies.

[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 can set the state of the housing, which is not in an open state, to a closed state. When the electronic device is in a closed state, the transmit power of the antenna can be limited so that the sum of the SAR values ​​of the antennas included in a plurality of antenna groups satisfies the SAR criteria. As the SAR values ​​of the antennas are limited, the transmit power used by the antennas may decrease. The electronic device may experience problems with the communication connection due to a lack of signal transmit power.

[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] An electronic device according to one embodiment may include a housing comprising a first housing portion and a second housing portion that are foldable or movable relative to each other. The electronic device may include a plurality of antenna groups, including a first antenna group located in the first housing portion and a second antenna group located in the second housing portion. The electronic device may include at least one communication circuit electrically connected to the plurality of antenna groups. The electronic device may include at least one sensor. The electronic device may include at least one processor electrically connected to the at least one communication circuit and the at least one sensor. The electronic device may include a memory for storing instructions. When the instructions are executed individually and / or collectively by the at least one processor, the electronic device may establish a connection with an external device through the at least one communication circuit. The instructions may enable the electronic device to check the state of the housing through the at least one sensor. The instructions may enable the electronic device to determine, based on the state of the housing, a correlation coefficient including the ratio in which the SAR value of at least one antenna included in a plurality of antenna groups is reflected in the SAR value of a first antenna group and the ratio in which the SAR value of at least one antenna included in the plurality of antenna groups is reflected in the SAR value of a second antenna group. The instructions may enable the electronic device to calculate the SAR value of each of at least one antenna included in the plurality of antenna groups based on the determined correlation coefficient, such that the first antenna group satisfies a first SAR criterion and the second antenna group satisfies a second SAR criterion.The instructions may cause the electronic device to transmit a signal to the external device with power allocated to at least one antenna included in the plurality of antenna groups in correspondence with the calculated SAR value.

[0007] An electronic device according to one embodiment may include a housing comprising a first housing portion and a second housing portion that are foldable or movable relative to each other. The electronic device may include a plurality of antenna groups, comprising a first antenna group located in the first housing portion and a second antenna group located in the second housing portion. The electronic device may include at least one communication circuit electrically connected to the plurality of antenna groups. The electronic device may include at least one sensor. The electronic device may include at least one processor electrically connected to the at least one communication circuit and the at least one sensor. The electronic device may include a memory for storing instructions. When the instructions are executed individually and / or collectively by the at least one processor, the electronic device may establish a connection with an external device through the at least one communication circuit. The instructions may enable the electronic device to check a changed state of the housing through the at least one sensor. The instructions may include a first specific absorption rate when the housing is in an open state. The electronic device may transmit a signal to the external device with power allocated to the first antenna group and the second antenna group based on the sum of the SAR values ​​of each antenna included in the first antenna group satisfying a SAR standard, and the sum of the SAR values ​​of each antenna included in the second antenna group satisfying a second SAR standard.The instructions may cause the electronic device to transmit a signal to the external device with power allocated to the first antenna group and the second antenna group based on the sum of the sum of the SAR values ​​of each antenna included in the first antenna group satisfying the first SAR criterion and the second SAR criterion, and the sum of the sum of the SAR values ​​of each antenna included in the second antenna group, when the housing is in a closed state. The instructions may cause the electronic device to transmit a signal to the external device with power allocated to the first antenna group and the second antenna group based on the sum of the sum of the SAR values ​​of each antenna included in the first antenna group satisfying the first SAR criterion and the sum of the sum of the partial SAR values ​​of each antenna included in the second antenna group satisfying the second SAR criterion, when the housing is in an intermediate state between the open state and the closed state.

[0008] The electronic device can calculate the SAR values ​​of antennas included in multiple antenna groups included in the electronic device in an intermediate state between an open state and a closed state. When the state of the housing is an intermediate state, the electronic device can calculate SAR values ​​of antennas that are greater than the SAR values ​​of antennas when in a closed state by using an antenna group correlation coefficient matrix corresponding to the intermediate state. The electronic device can use transmission power corresponding to the calculated SAR values. Even when the electronic device is not in an open state, by using the antenna group correlation coefficient corresponding to the intermediate state, it can use higher transmission power than when uniformly set to a closed state.

For example, the first hinge module (401) may be a first folding hinge, a wide hinge, or a big hinge that is wider than the second hinge module (402). For example, the second hinge module (402) may be a second folding hinge, slim hinge, or small hinge that is narrower than the first hinge module (401). In one embodiment, the first hinge module (401) may have a larger radius of curvature than the second hinge module (402).

For example, when the first housing (410) and the third housing (430) are in a folded state, at least a portion of the second hinge cover (402c) may be visually exposed to the outside between the first housing (410) and the third housing (430). The second hinge cover (402c) may include at least a partially curved surface. The second hinge cover (402c) may be formed of a conductive material (e.g., metal) and / or a non-conductive material (e.g., polymer).

[0089] According to various embodiments, the width of the first hinge cover (401c) may be configured to be wider than the width of the second hinge cover (402c). For example, since the first width of the first hinge module (401) is wider than the second width of the second hinge module (402), the width of the first hinge cover (401c) may be formed to be wider than the width of the second hinge cover (402c).

[0090] According to various embodiments, the foldable electronic device (400) disclosed below (e.g., multi-foldable electronic device) may include at least some of the embodiments described in FIGS. 1 to 6. Embodiments related to the foldable electronic device (400) disclosed below may be incorporated and applied, for example, to the embodiments of the foldable electronic device (400) disclosed in FIGS. 4a to 6. In the description of the foldable electronic device (400) according to various embodiments of the present invention disclosed below, the same reference numerals are assigned to components substantially identical to those disclosed in FIGS. 1 to 6, and redundant descriptions of their functions may be omitted.

[0091] FIG. 7 is a diagram illustrating the SAR value of an electronic device that controls transmission power according to the time average specific absorption rate (TAS) according to one embodiment.

[0092] The electronic device (100) may be required to comply with regulations regarding the specific absorption rate (SAR) (unit: W / kg (watts per kilogram)), which represents the energy absorption by human tissue per unit mass. For example, the electronic device (100) may be required to limit transmission power to comply with regulations regarding SAR. Regulations regarding SAR may include criteria where the SAR value measured during a SAR window (702), which is a defined time interval, is less than the maximum allowable SAR (e.g., target SAR) (701). The maximum allowable SAR (701) value may refer to a value set by domestic or international regulatory bodies. For example, the maximum allowable SAR (701) value may be a value set according to at least one of the following regulations: North American FCC (federal communications commission), Canadian ISED (innovation, science and economic development Canada), Japanese TELEC (telecommunications engineering center), Chinese NAR (network access license) (or NCC (national communications commission)), European RED (radio equipment directive) or Korean KC (korea certification).

[0093] According to one embodiment, an electronic device (100) may comply with SAR-related regulations even if the SAR value during a specific moment's SAR window (702) exceeds the maximum allowable SAR value (701). Domestic or international regulatory bodies recognize that SAR-related regulations are complied with if the time-averaged SAR (TAS) value during the SAR measurement cycle (703) does not exceed the maximum allowable SAR value (701). The TAS value may refer to the average value of the SAR value (710) of the electronic device (100) during the SAR measurement cycle (703). The SAR measurement cycle (703) may refer to the time interval for calculating the time-averaged SAR value as defined by domestic or international regulatory bodies. For example, the FCC defines the SAR measurement cycle (703) as 100 seconds for signals with a frequency of 3 GHz or less.

[0094] An electronic device (100) may be recognized as compliant with regulations related to SAR if, despite a SAR value (740, 770) at a specific moment that exceeds the maximum allowable SAR (701) value, the TAS value during the SAR measurement cycle (703) does not exceed the maximum allowable SAR (701) value. The electronic device (100) may calculate the SAR value during the next SAR window so that the TAS value during the SAR measurement cycle (703) does not exceed the maximum allowable SAR (701) value. The next SAR window may refer to the SAR window immediately following the current SAR window as well as the SAR window following a plurality of SAR windows.

[0095] For example, the electronic device (100) can calculate the SAR value (780) for the next SAR window such that the sum of the SAR values ​​(720, 730, 740, 750, 760, 770, 780) during the SAR measurement cycle (703) does not exceed the SAR budget (704) which refers to the SAR values ​​allowed within the SAR measurement cycle (703). For example, the electronic device (100) can calculate the SAR value (780) for the next SAR window such that the difference between the SAR budget (704) and the sum of the previously calculated (or previously measured) SAR values ​​(720, 730, 740, 750, 760, 770) during a specific SAR window does not exceed the value of the difference between the SAR budget (704) and the sum of the previously calculated (or previously measured) SAR values ​​(720, 730, 740, 750, 760, 770). The electronic device (100) can determine the transmission power of a plurality of antennas included in the electronic device (100) so that it can have a SAR value (780) during the calculated next SAR window.

[0096] The electronic device (100) of the present disclosure can calculate the SAR value during the next SAR window based on the TAS. The electronic device (100), which complies with SAR-related regulations based on the TAS value, can satisfy the regulatory agency's SAR-related regulations even if the SAR value at a specific moment exceeds the maximum allowable SAR (701) value, and therefore may not limit the maximum transmit power of the antenna to a power corresponding to the maximum allowable SAR (701) value. The electronic device (100) can prevent performance limitations that may occur as a result of satisfying the maximum allowable SAR (701) value (e.g., limiting the maximum transmit power to below the maximum allowable SAR (701) value) by using a maximum transmit power that exceeds the maximum allowable SAR (701) value.

[0097] FIG. 8 is a block diagram of an electronic device according to one embodiment.

[0098] According to one embodiment, the electronic device (800) may include a processor (810) (e.g., processor (110) of FIG. 1), a memory (820) (e.g., memory (120) of FIG. 1), a sensor (830) (e.g., sensor (170) of FIG. 1), a communication circuit (840) (e.g., communication circuit (160) of FIG. 1), a first antenna group (850) and / or a second antenna group (860). The electronic device (800) may include a separate antenna group in addition to the first antenna group (850) and the second antenna group (860). Various embodiments of this document may be implemented even if some of the illustrated configurations are omitted or replaced with other configurations. The electronic device (800) may further include at least some of the configurations and / or functions of the electronic device (100) of FIG. 1 in addition to the illustrated configurations. At least some of the components of each of the illustrated (or unillustrated) electronic devices (800) may be operatively, functionally, and / or electrically connected.

[0099] The processor (810) may include at least one processing circuitry, and the processor (810) may include at least one processor (810). The operations described in FIGS. 1 to 16 may be performed individually or collectively by at least one processor (810) included in the processor (810).

[0100] The processor (810) can receive data transmitted by an external device through a communication circuit (840) and perform various operations using the received data. Alternatively, the processor (810) can control the communication circuit (840) to transmit data to an external device.

[0101] The memory (820) can store at least one computer program, and at least one computer program may include instructions that can be executed by the processor (810). The operations described in FIGS. 1 through 16 can be performed according to the execution of instructions contained in the memory (820).

[0102] The sensor (830) can detect the arrangement between multiple housings. The arrangement between multiple housings may refer to the relative orientation (or angle) of each of the multiple housings. The arrangement between multiple housings may be distinguished by the state of the housings. According to one example, an electronic device (800) implemented with two housings (e.g., the electronic device (200) of FIG. 2)) may be distinguished by the arrangement between the two housings, which may include a closed state, an open state, and / or an intermediate state. The sensor (830) can detect the changed arrangement between multiple housings in response to a change in the arrangement between multiple housings and transmit it to the processor (810).

[0103] The first antenna group (850) may include at least one antenna (e.g., a first antenna, a second antenna). The second antenna group (860) may include at least one antenna (e.g., a third antenna, a fourth antenna). For example, antennas included in the same antenna group may be positioned adjacent to each other.

[0104] The processor (810) can establish a connection with an external device through a communication circuit (840). The processor (810) can perform wireless communication with the external device via short-range wireless communication or cellular wireless communication. Short-range wireless communication may refer to various communication methods that both the electronic device (800) and / or the external device can support. For example, wireless communication may be Wi-Fi. Cellular wireless communication may refer to various communication methods that both the electronic device (800) and / or the external device can support, and may be one of various cellular communications including 4th generation cellular communication (long-term evolution) and 5th generation cellular communication (new radio).

[0105] The processor (810) can check the state of the housing through the sensor (830). The electronic device (800) may include a plurality of housings. The processor (810) can detect the state of the plurality of housings based on the arrangement between the plurality of housings. The state of the housing may include an open state, a closed state, and / or an intermediate state. The intermediate state may include two or more states. Alternatively, the intermediate state may be excluded from the state of the housing. The processor (810) can detect the arrangement between the plurality of housings and check the state of the housing based on the detected arrangement between the plurality of housings.

[0106] The processor (810) can determine the SAR to peak location separation ratio (SPLSR) of the arrangement between the detected plurality of housings and determine the state of the housing corresponding to the determined SPLSR. The SPLSR of the present disclosure may refer to the SAR to peak location separation ratio (SPLSR) of at least two antenna groups among the plurality of antenna groups included in the electronic device (800).

[0107] The manufacturer of the electronic device (800) may pre-measure the SPLSR corresponding to each of the arrangements between multiple housings and store it in the memory (820) included in the electronic device (800). The processor (810) may check the SPLSR corresponding to the changed arrangement as the arrangement between multiple housings changes. The processor (810) may check the state of the housing corresponding to the checked SPLSR. However, the state of the housing may be set according to the arrangements between multiple housings corresponding to the SPLSR pre-measured by the manufacturer, and the processor (810) may check the state of the housing corresponding to the arrangement between multiple housings without checking the SPLSR. The arrangement between multiple housings may be set to a specific housing state (e.g., open state, closed state, or intermediate state) depending on whether the first SPLSR condition and / or the second SPLSR condition is satisfied. For example, the first SPLSR condition may include a condition where the SPLSR is less than 0.04. The second SPLSR condition may refer to a condition in which, for a specified value of the second SPLSR condition that is 0.04 or greater and less than 1, the SPLSR is less than or equal to the specified value of the second SPLSR condition.

[0108] The processor (810) can determine, based on the state of the housing, a correlation coefficient including the ratio in which the SAR value of at least one antenna included in a plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) is reflected in the SAR value of the first antenna group (850) and the ratio in which the SAR value of at least one antenna included in the plurality of antenna groups is reflected in the SAR value of the second antenna group (860).

[0109] According to one example, at least some of the arrangements among the plurality of housings may be set to an open state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) satisfy a first SAR to peak location separation ratio (SPLSR) condition. When at least some of the housings among the plurality of housings are arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be determined to be an open state.

[0110] According to one embodiment, the electronic device (800) can detect a placement between a plurality of housings where SPLSR is less than 0.04 and confirm that the state of the housing is open.

[0111] The processor (810) can calculate the SAR values ​​of the antennas included in the antenna group such that, when the housing is in an open state, the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criteria. For example, when the housing is in an open state, the processor (810) can calculate the SAR values ​​of the antennas included in the antenna group based on the antenna group correlation coefficient matrix corresponding to the open state.

[0112] The antenna group correlation coefficient matrix corresponding to the open state may be a matrix in which the correlation coefficient in which the SAR value of at least one antenna included in the second antenna group (860) is reflected in the SAR value of the first antenna group (850) and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna group (850) is reflected in the SAR value of the second antenna group (860) are each set to 0.

[0113] According to one embodiment, at least some of the arrangements among the plurality of housings may be set to a closed state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) do not satisfy the first SPLSR condition. When at least some of the housings among the plurality of housings are arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) do not satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be determined to be a closed state.

[0114] According to one embodiment, some of the arrangements of the plurality of housings may be set to a closed state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups included in the electronic device (800) do not satisfy the first SPLSR condition and the second SPLSR condition. If at least some of the housings among the plurality of housings are arranged such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups do not satisfy the first SPLSR condition and the second SPLSR condition, the arrangement state of at least some of the housings may be determined to be a closed state.

[0115] The processor (810) can determine (or calculate) the SAR values ​​of antennas included in at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) such that, when the housing is in a closed state, the sum of the SAR values ​​of the antennas included in at least two antenna groups satisfies the SAR criteria. For example, when the housing is in a closed state, the processor (810) can calculate the SAR values ​​of the antennas included in the antenna groups based on an antenna group correlation coefficient matrix corresponding to the closed state.

[0116] The antenna group correlation coefficient matrix corresponding to the closed state may be a matrix in which the correlation coefficient in which the SAR value of at least one antenna included in the second antenna group (860) is reflected in the SAR value of the first antenna group (850) and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna group (850) is reflected in the SAR value of the second antenna group (860) are each set to 1.

[0117] According to one embodiment, at least some of the arrangements among the plurality of housings may be set to an intermediate state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) do not satisfy the first SPLSR condition. If at least some of the housings among the plurality of housings are arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) do not satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be determined to be an intermediate state.

[0118] According to one embodiment, some of the arrangements of a plurality of housings may be set to an intermediate state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups included in the electronic device (800) do not satisfy the first SPLSR condition but satisfy the second SPLSR condition. When at least some of the housings among the plurality of housings are arranged such that they do not satisfy the first SPLSR condition but satisfy the second SPLSR condition, the state of at least some of the housings may be determined to be an intermediate state.

[0119] The processor (810) can determine (or calculate) the SAR values ​​of antennas included in at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) such that when the state of the housing is an intermediate state, the sum of the SAR values ​​of the antennas included in at least two antenna groups satisfies the SAR criteria. For example, when the state of the housing is an intermediate state, the processor (810) can determine (or calculate) the SAR values ​​of the antennas included in the antenna groups based on an antenna group correlation coefficient matrix corresponding to the intermediate state.

[0120] The antenna group correlation coefficient matrix corresponding to the intermediate state may be a matrix in which the ratio in which the SAR value of at least one antenna included in the second antenna group (860) is reflected in the SAR value of the first antenna group (850) and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna group (850) is reflected in the SAR value of the second antenna group (860) are each set to numbers between 0 and 1.

[0121] The processor (810) may be in the form of a foldable device composed of two housings. In the processor (810) in the form of a foldable device composed of two housings, the distance between two antenna groups may increase as the folding angle between the two housings increases. The SPLSR of the two antenna groups may decrease as the distance between the two antenna groups increases.

[0122] According to one embodiment, at least some of the housings among the plurality of housings may be arranged at a folding angle such that the first antenna group (850) and the second antenna group (860) satisfy the first SPLSR condition. When at least some of the housings among the plurality of housings are arranged at a folding angle such that the first antenna group (850) and the second antenna group (860) satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be set to an open state. According to one embodiment, the arrangement between the plurality of housings such that the first antenna group (850) and the second antenna group (860) have a folding angle such that the first SPLSR condition is satisfied may be set to an open state. The processor (810) [is] a folding angle (e.g., θ) corresponding to 0.04 of the first SPLSR condition. OPEN It can detect the arrangement between multiple housings with a folding angle greater than ) and confirm that the housing is in an open state.

[0123] According to one embodiment, some of the arrangements of a plurality of housings may be set to a closed state. For example, at least some of the housings among the plurality of housings may be arranged at a folding angle such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups included in the electronic device (800) do not satisfy the first SPLSR condition and the second SPLSR condition. If at least some of the housings among the plurality of housings are arranged at an angle such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups do not satisfy the first SPLSR condition and the second SPLSR condition, the arrangement state of at least some of the housings may be determined to be a closed state. The processor (810) sets the folding angle (e.g., θ) corresponding to a specified value of the second SPLSR condition. CLOSE It is possible to detect the arrangement between multiple housings with a folding angle smaller than ) and confirm that the state of the housing is closed.

[0124] According to one embodiment, some of the arrangements of the plurality of housings may be set to an intermediate state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups included in the electronic device (800) do not satisfy the first SPLSR condition but satisfy the second SPLSR condition. When at least some of the housings among the plurality of housings are arranged such that they do not satisfy the first SPLSR condition but satisfy the second SPLSR condition, the state of at least some of the housings may be determined to be an intermediate state. The processor (810) determines a folding angle (e.g., θ) corresponding to the minimum value of the distance between the first antenna group (850) and the second antenna group (860). OPENA folding angle that is less than or equal to ) and corresponds to the specified value of the second SPLSR condition (e.g., θ CLOSE It is possible to detect the arrangement between multiple housings that have a folding angle greater than or equal to ), and confirm that the state of the housing is an intermediate state.

[0125] An antenna group correlation coefficient matrix may include a plurality of antenna group correlation coefficient matrices corresponding to each of a plurality of intermediate states. An intermediate state may be divided into a plurality of intermediate states depending on whether at least two of the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) satisfy a third SPLSR condition. The third SPLSR condition may refer to a condition in which the SPLSR is less than or equal to the specified value of the third SPLSR condition for a specified value of the third SPLSR condition that is greater than 0.04 of the first SPLSR condition and less than the specified value of the second SPLSR condition. For example, the first intermediate state may refer to an intermediate state that satisfies the third SPLSR condition, and the second intermediate state may refer to an intermediate state that does not satisfy the third SPLSR condition.

[0126] The processor (810) can calculate the SAR value of each of at least one antenna included in a plurality of antenna groups (e.g., first antenna group (850) and second antenna group (860)) based on a correlation coefficient corresponding to the state of the housing, so that the first antenna group (850) satisfies the first SAR criterion and the second antenna group (860) satisfies the second SAR criterion.

[0127] When the state of the housing is open, the processor (810) checks the antenna group correlation coefficient matrix corresponding to the open state and can determine (or calculate) the SAR value of each antenna included in the plurality of antenna groups so that the antenna group satisfies the SAR criterion. For example, the SAR value of the first antenna group (850) can be calculated as the sum of the SAR value of the first antenna and the SAR value of the second antenna according to the antenna group correlation coefficient matrix corresponding to the open state described in Equation 12 included in the detailed description of FIG. 10. The processor (810) can calculate the SAR value of the first antenna and the SAR value of the second antenna so that the first antenna group (850) satisfies the first SAR criterion. For example, the SAR value of the second antenna group (860) can be calculated as the sum of the SAR value of the third antenna and the SAR value of the fourth antenna according to the antenna group correlation coefficient matrix corresponding to the open state of Equation 12. The processor (810) can calculate the SAR value of the third antenna and the SAR value of the fourth antenna so that the second antenna group (860) satisfies the second SAR standard. When the housing of the electronic device (800) of the present disclosure is in an open state, the sum of the SAR values ​​of the antennas included in the first antenna group (850) (e.g., the sum of the SAR value of the first antenna and the SAR value of the second antenna) may be referred to as the first SAR usage by the first antenna group (850). When the housing is in an open state, the sum of the SAR values ​​of the antennas included in the second antenna group (860) (e.g., the sum of the SAR value of the third antenna and the SAR value of the fourth antenna) may be referred to as the second SAR usage by the second antenna group (860).The processor (810) can calculate the first SAR usage and the second SAR usage based on setting the correlation coefficient between at least one antenna included in the first antenna group (850) and at least one antenna included in the second antenna group (860) to zero when the housing is in an open state. The processor (810) can transmit a signal to an external device with power allocated to the first antenna group (850) and the second antenna group (860) based on the first SAR usage by the first antenna group (850) satisfying the first SAR criterion and the second SAR usage by the second antenna group (860) satisfying the second SAR criterion when the housing is in an open state. The first SAR usage or the second SAR usage can be calculated based on the SAR budget for a specified time period.

[0128] When the state of the housing is an intermediate state, the processor (810) checks the antenna group correlation coefficient matrix corresponding to the intermediate state and can calculate the SAR value of each antenna included in the plurality of antenna groups so that the antenna groups satisfy the SAR criteria. For example, the SAR value of the first antenna group (850) can be calculated as the sum of a portion of the SAR value of the third antenna, a portion of the SAR value of the fourth antenna, the SAR value of the first antenna, and the SAR value of the second antenna, according to the antenna group correlation coefficient matrix corresponding to the intermediate state of Equation 12. The portion of the SAR value of the third antenna is the ratio in which the SAR value of the third antenna is reflected in the SAR value of the first antenna group (850) (e.g., r in Equation 12). 1,3 (θ)) and the product of the SAR value of the third antenna value may be referred to. A portion of the SAR value of the fourth antenna is the ratio in which the SAR value of the fourth antenna is reflected in the SAR value of the first antenna group (850) (e.g., r in Equation 12). 1,4(θ)) and the product of the SAR value of the fourth antenna value may be referred to. For example, the SAR value of the second antenna group (860) may be calculated as the sum of a portion of the SAR value of the first antenna, a portion of the SAR value of the second antenna, the SAR value of the third antenna, and the SAR value of the fourth antenna, according to the antenna group correlation coefficient matrix corresponding to the intermediate state of Equation 12. The portion of the SAR value of the first antenna is the ratio in which the SAR value of the first antenna is reflected in the SAR value of the second antenna group (860) (e.g., r in Equation 12). 2,1 (θ)) and the product of the SAR value of the first antenna value may be referred to. A portion of the SAR value of the second antenna is the ratio in which the SAR value of the second antenna is reflected in the SAR value of the second antenna group (860) (e.g., r in Equation 12). 2,2(θ)) and the product of the SAR value of the second antenna value may be referred to. When the housing of the electronic device (800) of the present disclosure is in an intermediate state, the sum of the SAR values ​​of the antennas included in the first antenna group (850) (e.g., the sum of the SAR value of the first antenna and the SAR value of the second antenna) may be referred to as the fifth SAR usage by the first antenna group (850). When the housing is in an intermediate state, the sum of the SAR values ​​of the antennas included in the second antenna group (860) (e.g., the sum of the SAR value of the third antenna and the SAR value of the fourth antenna) may be referred to as the sixth SAR usage by the second antenna group (860). The processor (810) can calculate the fifth SAR usage and the sixth SAR usage based on setting the correlation coefficient between at least one antenna included in the first antenna group (850) and at least one antenna included in the second antenna group (860) to a number between 0 and 1 when the housing is in an intermediate state. The processor (810) can transmit a signal to an external device with power allocated to the first antenna group (850) and the second antenna group (860) based on the fifth SAR usage by the first antenna group (850) satisfying the first SAR criterion and the sixth SAR usage by the second antenna group (860) satisfying the second SAR criterion when the housing is in an intermediate state. The fifth SAR usage or the sixth SAR usage can be calculated based on the SAR budget for a specified time.

[0129] When the state of the housing is closed, the processor (810) checks the antenna group correlation coefficient matrix corresponding to the closed state and can calculate the SAR value of each antenna included in the plurality of antenna groups so that the antenna groups satisfy the SAR criteria. For example, the SAR value of the first antenna group (850) (or the SAR value of the second antenna group (860)) can be calculated as the sum of the SAR value of the first antenna, the SAR value of the second antenna, the SAR value of the third antenna, and the SAR value of the fourth antenna according to the antenna group correlation coefficient matrix corresponding to the closed state of Equation 12. The processor (810) can calculate the SAR value of the first antenna, the SAR value of the second antenna, the SAR value of the third antenna, and the SAR value of the fourth antenna so that the first antenna group (850) (or the second antenna group (860)) satisfies the first SAR criteria (or the second SAR criteria). When the housing of the electronic device (800) of the present disclosure is in a closed state, the sum of the SAR values ​​of the antennas included in the first antenna group (850) (e.g., the sum of the SAR value of the first antenna and the SAR value of the second antenna) may be referred to as the third SAR usage by the first antenna group (850). When the housing is in an intermediate state, the sum of the SAR values ​​of the antennas included in the second antenna group (860) (e.g., the sum of the SAR value of the third antenna and the SAR value of the fourth antenna) may be referred to as the fourth SAR usage by the second antenna group (860). When the housing is in a closed state, the processor (810) may calculate the third SAR usage and the fourth SAR usage based on setting the correlation coefficient between at least one antenna included in the first antenna group (850) and at least one antenna included in the second antenna group (860) to 1.When the housing is closed, the processor (810) can transmit a signal to an external device with power allocated to the first antenna group (850) and the second antenna group (860) based on the third SAR usage by the first antenna group (850) satisfying the first SAR criterion and the fourth SAR usage by the second antenna group (860) satisfying the second SAR criterion. The third SAR usage or the fourth SAR usage may be calculated based on a SAR budget for a specified period of time.

[0130] The processor (810) can determine the signal strength to be output by each of the plurality of antennas included in the plurality of antenna groups (e.g., the first antenna group (850) and the second antenna group (860)) based on the calculated SAR value. The processor (810) can control the communication circuit (840) so that the plurality of antennas radiate a signal having the determined strength.

[0131] FIG. 9a is a drawing illustrating an antenna group of an electronic device according to one embodiment.

[0132] The electronic device (800) may include a first antenna group (850) including a first antenna (851) and a second antenna (852), and a second antenna group (860) including a third antenna (863) and a fourth antenna (864). The electronic device (800) may include separate antenna groups in addition to the first antenna group (850) and the second antenna group (860), and each antenna group may include three or more antennas. The description below may apply to antenna groups and antennas that may be included in the electronic device (800).

[0133] An antenna group (e.g., first antenna group (850), second antenna group (860)) may be assigned an antenna group SAR value calculated to comply with regulations related to SAR. For example, an antenna group (e.g., first antenna group (850), second antenna group (860)) may be assigned an antenna group SAR value calculated to satisfy a SAR standard, which is a regulation related to SAR corresponding to the antenna group. The SAR standard may refer to a standard in which the TAS value of the antenna group during the SAR measurement cycle is less than the maximum allowable SAR value.

[0134] SAR standards may be set for each antenna group (e.g., first antenna group (850), second antenna group (860)). For example, the first antenna group (850) may be set to satisfy the first SAR standard, and the second antenna group (860) may be set to satisfy the second SAR standard. The first SAR standard and the second SAR standard may be substantially the same standard. For example, the first SAR standard and the second SAR standard may each be a standard with a maximum allowable SAR value of 1.6 W / kg. The first SAR standard or the second SAR standard may be set based on a time-averaged SAR (TAS) standard that satisfies the SAR standard for a specified period of time.

[0135] A SAR standard according to one embodiment can be expressed by [Equation 1] or [Equation 2]. N may refer to the SAR measurement period. SAR AG (nj) can refer to the SAR value of the antenna group at nj seconds. SAR AG (n) can refer to the SAR value of the antenna group at n seconds. SAR target It can refer to the maximum allowable SAR value.

[0136]

[0137] According to [Equation 1], the SAR reference is the TAS value of the antenna group during the SAR measurement cycle (e.g., of [Equation 1] ) is the maximum allowable SAR value (e.g., SAR in Equation 1) target A standard less than ) can be referred to. The TAS value of the antenna group can be determined as the average value of the SAR values ​​of the antenna group during the SAR measurement cycle.

[0138]

[0139] According to [Equation 2], the SAR value of the antenna group can be calculated such that the antenna group (e.g., first antenna group (850), second antenna group (860)) satisfies the SAR criteria. The SAR value of the antenna group (e.g., the SAR of [Equation 2] AG (n)) is the SAR budget (e.g., N in [Equation 2] SAR target ) and the sum of the previously calculated (or previously measured) SAR values ​​of the antenna group during the SAR measurement cycle (e.g., of [Equation 2] It can be calculated as a value less than the difference value of ).

[0140] The SAR value of an antenna group can be calculated based on the SAR values ​​of antennas included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) included in the electronic device (800). The SAR value of an antenna group can be calculated based on the SAR values ​​of antennas included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) included in the electronic device (800) and an antenna group correlation matrix. For example, the SAR value of an antenna group can be calculated as the sum of the values ​​obtained by multiplying the SAR value of an antenna included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) included in the electronic device (800) by the correlation coefficients included in the antenna group correlation matrix corresponding to each antenna.

[0141] The correlation coefficient included in the antenna group correlation coefficient matrix may refer to the ratio in which the SAR value of at least one antenna included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) is reflected in the SAR value of an individual antenna group. The ratio in which the SAR value of a specific antenna is reflected in the SAR value of an antenna group that includes that specific antenna may be set to 1. For example, the ratio in which the SAR value of at least one antenna included in the first antenna group (850) is reflected in the SAR value of the first antenna group (850) and the ratio in which the SAR value of at least one antenna included in the second antenna group (860) is reflected in the SAR value of the second antenna group (860) may each be set to 1.

[0142] The antenna group correlation coefficient matrix can be expressed as [Equation 3]. [Equation 3] may be an equation expressing the antenna group correlation coefficient matrix between two antenna groups and the antennas included in the two antenna groups.

[0143]

[0144] In [Equation 3], M may refer to the total number of antennas included in two antenna groups (e.g., first antenna group (850), second antenna group (860)). i,j can refer to the correlation coefficient between the i-th antenna group and the j-th antenna. i,j can be set to a value between 0 and 1, and r i,j If α is 0, it indicates that the SAR value of the j-th antenna is independent of whether the i-th antenna group satisfies the SAR criterion. r i,j If α is 1, it may indicate that the entire SAR value of the j-th antenna must be reflected to determine whether the i-th antenna group satisfies the SAR criteria.

[0145] The electronic device (800) can calculate the SAR value of each antenna included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) based on an antenna group correlation coefficient matrix so that the antenna groups satisfy the SAR criteria.

[0146] For example, the electronic device (800) can determine the SAR values ​​of each of the antennas included in the first antenna group (850) and the second antenna group (860) based on the antenna group correlation coefficient matrix such that the first antenna group (850) satisfies the first SAR criterion and the second antenna group (860) satisfies the second SAR criterion.

[0147] The electronic device (800) can calculate the SAR value of each antenna included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) so that the antenna group can have a SAR value confirmed (or calculated) using [Equation 2]. According to one example, the electronic device (800) can confirm the SAR value of an antenna group by multiplying the correlation coefficients included in the antenna group correlation coefficient matrix described in Equation 3 with the SAR value of each antenna included in the plurality of antenna groups, and can determine (or confirm) the SAR of each antenna included in the plurality of antenna groups so that the confirmed SAR value is the same as the SAR value confirmed using Equation 2.

[0148] For example, the SAR value of an antenna group, expressed as the sum of the products of the SAR values ​​of antennas included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) included in the electronic device (800) and the correlation coefficients included in the antenna group correlation coefficient matrix corresponding to each antenna, may be as in [Equation 4]. In [Equation 4], SAR AG i (n) may refer to the SAR value at n seconds (or the nth SAR window) of the i-th antenna group (e.g., the first antenna group (850), the second antenna group (860)). SAR AT i (n) may refer to the SAR value at n seconds (or nth SAR window) of the i-th antenna (e.g., first antenna (851), second antenna (852), third antenna (863), fourth antenna (864)) included in a plurality of antenna groups.

[0149]

[0150] According to one embodiment, SAR in [Equation 4] AG i(n) can be set to the SAR value of the antenna group calculated to satisfy the SAR criteria according to [Equation 2].

[0151] The electronic device (800) may include a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)). The SAR value of each of the plurality of antenna groups may be expressed as the sum of the values ​​obtained by multiplying the SAR value of an antenna included in the plurality of antenna groups included in the electronic device (800) by the correlation coefficient included in the antenna group correlation coefficient matrix corresponding to each antenna, as in [Equation 5]. In [Equation 5], It may be a column vector composed of SAR values ​​of a plurality of antenna groups included in the electronic device (800). For example, it may be a matrix composed of SAR values ​​of a first antenna group (850) and a second antenna group (860) included in the electronic device (800).

[0152]

[0153] The SAR values ​​of a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) included in the electronic device (800) can be calculated to satisfy the SAR criteria. For example, each of the first antenna group (850) and the second antenna group (860) included in the electronic device (800) can use a transmission power corresponding to a SAR value that satisfies the SAR criteria according to [Equation 2].

[0154] The SAR values ​​of antennas included in a plurality of antenna groups (e.g., a first antenna group (850), a second antenna group (860)) can be calculated such that the plurality of antenna groups satisfy the SAR criteria. The SAR values ​​of antennas included in the plurality of antenna groups can be calculated such that the antenna groups have the calculated SAR values. For example, the SAR values ​​of antennas included in the plurality of antenna groups can be calculated such that they satisfy [Equation 6].

[0155]

[0156] The electronic device (800) can calculate the SAR value of an antenna group (e.g., a first antenna group (850), a second antenna group (860)) according to [Equation 2] and calculate the SAR value of antennas included in a plurality of antenna groups corresponding to the calculated SAR value of the antenna group. The electronic device (800) can use the correlation coefficients included in the antenna group correlation coefficient matrix to calculate the SAR value of antennas included in the plurality of antenna groups.

[0157] The electronic device (800) may include a plurality of housings. The electronic device (800) may detect the state of the plurality of housings based on the arrangement between the plurality of housings. The state of the housings may include an open state (801) and / or a closed state (802). The electronic device (800) may detect the arrangement between the plurality of housings and check the state of the housings based on the detected arrangement.

[0158] The electronic device (800) can calculate the SAR values ​​of the antennas included in the antenna group such that the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criteria. The electronic device (800) can calculate the SAR values ​​of the first antenna (851) and / or the second antenna (852) such that the sum of the SAR values ​​of the antennas included in the first antenna group (850) satisfies the first SAR criteria. The electronic device (800) can calculate the SAR values ​​of the third antenna (863) and / or the fourth antenna (864) such that the sum of the SAR values ​​of the antennas included in the second antenna group (860) satisfies the second SAR criteria.

[0159] The electronic device (800) can calculate the SAR values ​​of the antennas included in the antenna group such that, when the housing state is open state (801), the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criteria. For example, when the housing state is open state (801), the electronic device (800) can calculate the SAR values ​​of the antennas included in the antenna group based on the antenna group correlation coefficient matrix corresponding to the open state (801).

[0160] The antenna group correlation coefficient matrix corresponding to the open state (801) may be a matrix in which the correlation coefficient in which the SAR value of at least one antenna included in the second antenna group (860) is reflected in the SAR value of the first antenna group (850) and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna group (850) is reflected in the SAR value of the second antenna group (860) are each set to 0. For example, the antenna group correlation coefficient matrix corresponding to the open state (801) may be a matrix (R) set as in Equation 7. OPEN It can be.

[0161]

[0162] In Equation 7, the ratio in which the SAR value of the antenna included in the second antenna group (860) (e.g., third antenna (863) and fourth antenna (864)) is reflected in the SAR value of the first antenna group (850) (e.g., r 1,3 and r 1,4 ) and the ratio in which the SAR value of the antenna included in the first antenna group (850) (e.g., first antenna (851) and second antenna (852)) is reflected in the SAR value of the second antenna group (860) (e.g., r 2,1 and r 2,2 ) can be set to 0.

[0163] The electronic device (800) can calculate the SAR values ​​of antennas included in at least two antenna groups such that the sum of the SAR values ​​of the antennas included in at least two antenna groups satisfies the SAR criteria. The electronic device (800) can calculate the SAR of the first antenna (851), the second antenna (852), the third antenna (863), and / or the fourth antenna (864) such that the sum of the SAR values ​​of the antennas included in the first antenna group (850) and the second antenna group (860) satisfies the SAR criteria (e.g., the first SAR criteria or the second SAR criteria).

[0164] The electronic device (800) can calculate the SAR values ​​of antennas included in at least two antenna groups such that, when the housing state is closed state (802), the sum of the SAR values ​​of antennas included in at least two antenna groups satisfies the SAR criteria. For example, when the housing state is closed state (802), the electronic device (800) can calculate the SAR values ​​of antennas included in antenna groups based on the antenna group correlation coefficient matrix corresponding to the closed state (802).

[0165] The antenna group correlation coefficient matrix corresponding to the closed state (802) may be a matrix in which the correlation coefficient in which the SAR value of at least one antenna included in the second antenna group (860) is reflected in the SAR value of the first antenna group (850) and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna group (850) is reflected in the SAR value of the second antenna group (860) are each set to 1. For example, the antenna group correlation coefficient matrix corresponding to the closed state (802) may be a matrix (R) set as in [Equation 8]. CLOSE It can be.

[0166]

[0167] In [Equation 8], the ratio in which the SAR value of the antenna included in the second antenna group (860) (e.g., third antenna (863) and fourth antenna (864)) is reflected in the SAR value of the first antenna group (850) (e.g., r 1,3 and r 1,4 ) and the ratio in which the SAR value of the antenna included in the first antenna group (850) (e.g., first antenna (851) and second antenna (852)) is reflected in the SAR value of the second antenna group (860) (e.g., r 2,1 and r 2,2 ) can be set to 1.

[0168] FIG. 9b is a diagram showing the SAR value of an antenna group included in an electronic device according to one embodiment.

[0169] The SAR value graph (901) of the first antenna group (850) and the SAR value graph (902) of the second antenna group (860) are graphs showing the SAR values ​​of the first antenna group (850) and the second antenna group (860) in the open state (801) and the closed state (802).

[0170] The electronic device (800) can calculate the SAR value of an antenna group (e.g., a first antenna group (850) or a second antenna group (860)) according to Equation 1 or Equation 2. For example, the electronic device (800) calculates the SAR value of the antenna group (e.g., a first antenna group (850) or a second antenna group (860)) using a SAR budget (e.g., N in Equation 2). SAR target ) and the sum of the previously calculated (or previously measured) SAR values ​​of the antenna group during the SAR measurement cycle (e.g., of Equation 2 It can be calculated as a value smaller than the difference value of ). The SAR value of the first antenna group is calculated based on the maximum allowable SAR value (903) corresponding to the first SAR standard, and the SAR value of the second antenna group can be calculated based on the maximum allowable SAR value (904) corresponding to the second SAR standard.

[0171] The electronic device (800) can calculate the SAR value of each antenna included in a plurality of antenna groups (e.g., first antenna (851), second antenna (852), third antenna (863), fourth antenna (864)) so that the antenna group can have the calculated SAR value of the antenna group (e.g., first antenna group (850) or second antenna group (860)). According to one example, the electronic device (800) can determine the SAR value of the antenna group by multiplying the correlation coefficients included in the antenna group correlation coefficient matrix described in Equation 3 with the SAR value of each antenna included in the plurality of antenna groups, and can determine (or verify) the SAR of each antenna included in the plurality of antenna groups such that the verified SAR value is the same as the SAR value verified using Equation 2.

[0172] Hereinafter, an embodiment will be described in which an electronic device (800) calculates the SAR value of each antenna included in antenna groups based on an antenna group correlation coefficient matrix corresponding to the state of the housing.

[0173] The state of the housing may be open (801) during the first period (910). The electronic device (800) may calculate the SAR values ​​of the antennas included in the antenna group such that, when the state of the housing is open (801), the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criteria. The electronic device (800) may control the antennas included in the individual antenna group to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0174] The electronic device (800) can check the antenna group correlation coefficient matrix corresponding to the open state (801) when the housing state is open state (801), and calculate the SAR value of each antenna included in the plurality of antenna groups so that the antenna group satisfies the SAR criterion. For example, the SAR value (911) of the first antenna group (850) can be calculated as the sum (911) of the SAR value of the first antenna (851) and the SAR value of the second antenna (852) according to the antenna group correlation coefficient matrix of Equation 7. The electronic device (800) can calculate the SAR value of the first antenna (851) and the SAR value of the second antenna (852) so that the first antenna group (850) satisfies the first SAR criterion. For example, the SAR value (912) of the second antenna group (860) can be calculated as the sum of the SAR value of the third antenna (863) and the SAR value of the fourth antenna (864) according to the antenna group correlation coefficient matrix of Equation 7. The electronic device (800) can calculate the SAR value of the third antenna (863) and the SAR value of the fourth antenna (864) so ​​that the second antenna group (860) satisfies the second SAR standard.

[0175] The state of the housing may be changed from an open state (801) to a closed state (802) and may remain in a closed state (802) for a second period (920). When the housing is in a closed state (802), the electronic device (800) may calculate the SAR values ​​of the antennas included in at least two antenna groups (e.g., a first antenna (851), a second antenna (852), a third antenna (863), a fourth antenna (864)) such that the sum of the SAR values ​​of the antennas included in at least two antenna groups satisfies the SAR criteria. The electronic device (800) may control the antennas included in at least two antenna groups to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0176] When the state of the housing is closed state (802), the electronic device (800) can check the antenna group correlation coefficient matrix corresponding to the closed state (802) and calculate the SAR value of each antenna included in a plurality of antenna groups so that the antenna group satisfies the SAR criteria. For example, the SAR value (921) of the first antenna group (850) (or the SAR value (922) of the second antenna group (860)) can be calculated as the sum of the SAR values ​​of the antennas included in the first antenna group (e.g., the sum of the SAR value of the first antenna and the SAR value of the second antenna) (9210) and the sum of the SAR values ​​of the antennas included in the second antenna group (e.g., the sum of the SAR value of the third antenna and the SAR value of the fourth antenna) (9220), according to the antenna group correlation coefficient matrix of Equation 8. The electronic device (800) can calculate the SAR value of the first antenna, the SAR value of the second antenna, the SAR value of the third antenna, and the SAR value of the fourth antenna so that the first antenna group (850) (or the second antenna group (860)) satisfies the first SAR criterion (or the second SAR criterion).

[0177] The state of the housing may be changed from a closed state (802) to an open state (801) and may remain in an open state (801) for a third period (930). When the state of the housing is in an open state (801), the electronic device (800) may calculate the SAR values ​​of the antennas included in the antenna group such that the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criteria. The electronic device (800) may control the antennas included in the individual antenna group to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0178] When the state of the housing is open state (801), the electronic device (800) can check the antenna group correlation coefficient matrix corresponding to the open state (801) and calculate the SAR value of each antenna included in the plurality of antenna groups so that the antenna group satisfies the SAR criterion. For example, the SAR value (931) of the first antenna group (850) can be calculated as the sum of the SAR value of the first antenna and the SAR value of the second antenna according to the antenna group correlation coefficient matrix of Equation 7. The electronic device (800) can calculate the SAR value of the first antenna and the SAR value of the second antenna so that the first antenna group (850) satisfies the first SAR criterion. For example, the SAR value (932) of the second antenna group (860) can be calculated as the sum of the SAR value of the third antenna and the SAR value of the fourth antenna according to the antenna group correlation coefficient matrix of Equation 7. The electronic device (800) can calculate the SAR value of the third antenna and the SAR value of the fourth antenna so that the second antenna group (860) satisfies the second SAR standard.

[0179] The electronic device (800) can set the state of the housing to a closed state (802) when it is not in an open state (801). When the electronic device is in a closed state, the transmission power of the antenna may be limited so that the sum of the SAR values ​​of the antennas included in a plurality of antenna groups satisfies the SAR standard. For example, the electronic device (800) may need to determine the SAR values ​​of the antennas included in the first antenna group (850) and the second antenna group (860) so that the sum of the SAR values ​​of the antennas included in the first antenna group (850) and the second antenna group (860) satisfies the first SAR standard and the second SAR standard. As the SAR values ​​of the antennas decrease, the transmission power used by the antennas may decrease. The electronic device (800) may experience problems with the communication connection due to a lack of signal transmission power. Below, we will explain how the electronic device (800) solves the problem of insufficient power for transmitting signals by calculating the SAR values ​​of the antennas included in the first antenna group (850) and the second antenna group (860) in an intermediate state between the open state (801) and the closed state (802).

[0180] FIG. 10 is a diagram illustrating the distance between a first antenna group and a second antenna group of an electronic device according to one embodiment.

[0181] The electronic device (800) may include a plurality of housings (e.g., a first housing portion (1010), a second housing portion (1020). The electronic device (800) may detect the state of the plurality of housings based on the arrangement between the plurality of housings. The state of the housing may include an open state (801), a closed state (802), and / or an intermediate state (803). The intermediate state (803) may include two or more states. The intermediate state (803) may be excluded from the state of the housing. The electronic device (800) may detect the arrangement between the plurality of housings and determine the state of the housing based on the detected arrangement between the plurality of housings. The electronic device (800) illustrated in FIG. 10 may be an example of an electronic device in which the state of the housing is an intermediate state (803), but it should be understood that the arrangement between the plurality of housings illustrated in FIG. 10 is not the only intermediate state (803).

[0182] The electronic device (800) can determine the SAR to peak location separation ratio (SPLSR) of the arrangement between the detected plurality of housings and determine the state of the housing corresponding to the determined SPLSR. The SPLSR of the present disclosure may refer to the SAR to peak location separation ratio (SPLSR) of at least two antenna groups among the plurality of antenna groups included in the electronic device (800). The SPLSR can be expressed as [Equation 9].

[0183]

[0184] In [Equation 9], D is the minimum distance between antenna groups, SAR SA 1 may refer to the standalone SAR value measured when the first antenna group (850) radiates a signal independently. SAR SA2 may refer to the SAR value measured when the second antenna group (860) radiates a signal independently. For example, SAR SA 1 may be the same value as the maximum allowable SAR value of the first SAR standard, and SAR SA 2 may be the same value as the maximum allowable SAR value of the second SAR standard.

[0185] The manufacturer of the electronic device (800) may pre-measure the SPLSR corresponding to each of the arrangements between multiple housings and store it in memory included in the electronic device (800). The electronic device (800) may check the SPLSR based on the changed arrangement as the arrangement between multiple housings changes. The electronic device (800) may check the state of the housing corresponding to the checked SPLSR. However, the state of the housing may be set according to the arrangements between multiple housings corresponding to the SPLSR pre-measured by the manufacturer, and the electronic device (800) may check the state of the housing based on the arrangement between multiple housings without checking the SPLSR. The arrangement between multiple housings may be set to a specific housing state (e.g., open state (801), closed state (802), or intermediate state (803)) depending on whether the first SPLSR condition and / or the second SPLSR condition is satisfied. The first SPLSR condition may include a condition where the SPLSR is less than 0.04. The second SPLSR condition may refer to a condition in which, for a specified value of the second SPLSR condition that is 0.04 or greater and less than 1, the SPLSR is less than or equal to the specified value of the second SPLSR condition.

[0186] According to one example, at least some of the arrangements among the plurality of housings may be set to an open state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) satisfy a first SAR to peak location separation ratio (SPLSR) condition. When at least some of the housings among the plurality of housings are arranged such that at least two antenna groups among the plurality of antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be determined to be an open state (801).

[0187] According to one embodiment, the electronic device (800) can detect a placement between a plurality of housings where SPLSR is less than 0.04 and confirm that the state of the housing is an open state (801).

[0188] According to one embodiment, at least some of the arrangements between the plurality of housings may be set to a closed state. At least some of the housings among the plurality of housings may be arranged such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups included in the electronic device (800) do not satisfy the first SPLSR condition.

[0189] For example, at least some of the housings among the plurality of housings may be positioned such that at least two antenna groups (e.g., a first antenna group (850) and a second antenna group (860)) among the plurality of antenna groups included in the electronic device (800) do not satisfy the first SPLSR condition and the second SPLSR condition.

[0218] The electronic device (800) can calculate the SAR value of an antenna group (e.g., a first antenna group (850) or a second antenna group (860)) according to Equation 1 or Equation 2. For example, the electronic device (800) calculates the SAR value of the antenna group (e.g., a first antenna group (850) or a second antenna group (860)) using the SAR budget (e.g., N in Equation 2). SAR target ) and the sum of the previously calculated (or previously measured) SAR values ​​of the antenna group during the SAR measurement cycle (e.g., of Equation 2 It can be calculated as a value smaller than the difference value of ). The SAR value of the first antenna group is calculated based on the maximum allowable SAR value (903) corresponding to the first SAR standard, and the SAR value of the second antenna group can be calculated based on the maximum allowable SAR value (904) corresponding to the second SAR standard.

According to one example, the electronic device (800) can determine the SAR value of the antenna group by multiplying the correlation coefficients included in the antenna group correlation coefficient matrix described in Equation 11 with the SAR value of each antenna included in the plurality of antenna groups, and can determine (or determine) the SAR of each antenna included in the plurality of antenna groups such that the determined SAR value is the same as the SAR value determined using Equation 2.

[0220] Hereinafter, an embodiment will be described in which an electronic device (800) calculates the SAR value of each antenna included in antenna groups based on an antenna group correlation coefficient matrix corresponding to the state of the housing.

[0221] The state of the housing may be open (801) during the first period (1110). The electronic device (800) may calculate the SAR values ​​of the antennas included in the antenna group such that, when the state of the housing is open (801), the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criteria. The electronic device (800) may control the antennas included in the individual antenna group to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0222] When the state of the housing is open state (801), the electronic device (800) can check the antenna group correlation coefficient matrix corresponding to the open state (801) and calculate the SAR value of each antenna included in the plurality of antenna groups so that the antenna group satisfies the SAR criterion. For example, the SAR value (1111) of the first antenna group (850) can be calculated as the sum of the SAR value of the first antenna (851) and the SAR value of the second antenna (852) according to the antenna group correlation coefficient matrix corresponding to the open state (801) of Equation 12. The electronic device (800) can calculate the SAR value of the first antenna (851) and the SAR value of the second antenna (852) so that the first antenna group (850) satisfies the first SAR criterion. For example, the SAR value (1112) of the second antenna group (860) can be calculated as the sum of the SAR value of the third antenna (863) and the SAR value of the fourth antenna (864) according to the antenna group correlation coefficient matrix corresponding to the open state (801) of Equation 12. The electronic device (800) can calculate the SAR value of the third antenna (863) and the SAR value of the fourth antenna (864) so ​​that the second antenna group (860) satisfies the second SAR standard.

[0223] The state of the housing is changed from an open state (801) to an intermediate state (803), and may remain in the intermediate state (803) during a second period (1120). When the housing is in the intermediate state (803), the electronic device (800) can calculate the SAR values ​​of the antennas included in at least two antenna groups such that the sum of the SAR values ​​of the antennas included in at least two antenna groups satisfies the SAR criteria. The electronic device (800) can control the antennas included in at least two antenna groups to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0224] The electronic device (800), when the state of the housing is an intermediate state (803), checks the antenna group correlation coefficient matrix corresponding to the intermediate state (803) and can calculate the SAR value of each antenna included in a plurality of antenna groups so that the antenna groups satisfy the SAR criteria. For example, the SAR value of the first antenna group (850) can be calculated as the sum of the sum (11211) of a portion of the SAR value of the third antenna (863) and a portion of the SAR value of the fourth antenna (864), and the sum (11210) of the SAR value of the first antenna (851) and the SAR value of the second antenna (852), according to the antenna group correlation coefficient matrix corresponding to the intermediate state (803) of Equation 12. The portion of the SAR value of the third antenna (863) is the ratio in which the SAR value of the third antenna (863) is reflected in the SAR value of the first antenna group (850) (e.g., r in Equation 12). 1,3 (θ)) and the SAR value of the third antenna (863) may be referred to as the product of the SAR values. A portion of the SAR value of the fourth antenna (864) is the ratio in which the SAR value of the fourth antenna (864) is reflected in the SAR value of the first antenna group (850) (e.g., r in Equation 12). 1,4 (θ)) and the SAR value of the fourth antenna (864) can be referred to as the product of the SAR values. For example, the SAR value (1122) of the second antenna group (860) can be calculated as the sum of the sum (11221) of a portion of the SAR value of the first antenna (851) and a portion of the SAR value of the second antenna (852), and the sum (11220) of the SAR value of the third antenna (863) and the SAR value of the fourth antenna (864), according to the antenna group correlation coefficient matrix corresponding to the intermediate state (803) of Equation 12. The portion of the SAR value of the first antenna (851) is the ratio in which the SAR value of the first antenna (851) is reflected in the SAR value of the second antenna group (860) (e.g., r in Equation 12). 2,1(θ)) and the SAR value of the first antenna (851) may be referred to as the product of the SAR value. A portion of the SAR value of the second antenna (852) is the ratio in which the SAR value of the second antenna (852) is reflected in the SAR value of the second antenna group (860) (e.g., r in Equation 12). 2,2 (θ)) and the SAR value of the second antenna (852) can be referred to as the product of the values.

[0225] The state of the housing may be changed from an intermediate state (803) to a closed state (802), and may remain in the closed state (802) for a third period (1130). When the housing is in the closed state (802), the electronic device (800) may calculate the SAR values ​​of the antennas included in at least two antenna groups such that the sum of the SAR values ​​of the antennas included in at least two antenna groups satisfies the SAR criteria. The electronic device (800) may control the antennas included in at least two antenna groups to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0226] When the state of the housing is closed state (802), the electronic device (800) can check the antenna group correlation coefficient matrix corresponding to the closed state (802) and calculate the SAR value of each antenna included in a plurality of antenna groups so that the antenna groups satisfy the SAR criteria. For example, the SAR value (1131) of the first antenna group (850) (or the SAR value (1132) of the second antenna group (860)) can be calculated as the sum of the SAR values ​​of the antennas included in the first antenna group (e.g., the sum of the SAR value of the first antenna and the SAR value of the second antenna) (11310) and the sum of the SAR values ​​of the antennas included in the second antenna group (e.g., the sum of the SAR value of the third antenna and the SAR value of the fourth antenna) (11320), according to the antenna group correlation coefficient matrix corresponding to the closed state (802) of Equation 12. The electronic device (800) can calculate the SAR value of the first antenna (851), the SAR value of the second antenna (852), the SAR value of the third antenna (863), and the SAR value of the fourth antenna (864) so ​​that the first antenna group (850) (or the second antenna group (860)) satisfies the first SAR criterion (or the second SAR criterion).

[0227] The electronic device (800) calculates the SAR values ​​of antennas included in the first antenna group (850) and the second antenna group (860) in an intermediate state (803) between the open state (801) and the closed state (802), and can calculate the SAR values ​​of antennas that are larger than those in the closed state (802) by using an antenna group correlation coefficient matrix corresponding to the intermediate state (803). The electronic device (800) may use higher transmission power when it is not in the open state (801) than when it is uniformly set to the closed state (802).

Hereinafter, the electronic device in the form (1321) corresponding to the first folding method (1241) will be described, but the details described below may be equally applied to the electronic device in the form (1322) corresponding to the second folding method (1242) (or the third folding method (1243)).

[0244] The electronic device (1200) may include a plurality of housings (e.g., a first housing portion (1201), a second housing portion (1202), and a third housing portion (1203). The electronic device (1200) may detect the state of the plurality of housings based on the arrangement between the plurality of housings. The state of the housing may include an open state (1301), a closed state (1302), and / or an intermediate state (1303). The intermediate state (1303) may include two or more states. The intermediate state (1303) may be excluded from the state of the housing. The electronic device (1200) may detect the arrangement between the plurality of housings and determine the state of the housing based on the detected arrangement between the plurality of housings.

[0245] Hereinafter, the electronic device (1200) will describe the state of the housing according to the distance between the first antenna group (1210) and the third antenna group (1230).

[0246] At least some of the arrangements among the plurality of housings may be arranged such that at least two of the plurality of antenna groups (e.g., a first antenna group (1210) and a third antenna group (1230)) satisfy the first SPLSR condition. At least some of the plurality of housings may be set to an open state (1301) when at least two of the plurality of antenna groups (e.g., a first antenna group (1210) and a third antenna group (1230)) are arranged such that they satisfy the first SPLSR condition.

[0248] At least some of the arrangements between the plurality of housings may be set to a closed state (1302) when at least two of the plurality of antenna groups (e.g., a first antenna group (1210) and a third antenna group (1230)) are arranged so as not to satisfy the first SPLSR condition.

In the electronic device (1200) in the form of a foldable device composed of three housings, the distance between two antenna groups (e.g., first antenna group (1210) and third antenna group (1230)) may vary depending on the folding angles between two adjacent housings (e.g., first folding angle (1311, 1321) and second folding angle (1312, 1322)). As the distance between the two antenna groups varies, the SPLSR of the two antenna groups may vary. Below, the state of the housing of the electronic device (1200) in the form of a foldable device composed of three housings and including three antenna groups will be described.

[0253] According to one embodiment, whether the arrangement (1231) between a plurality of housings satisfies the first SPLSR condition (or the second SPLSR condition) can be determined based on the distance (1310, 1320) between two antenna groups (e.g., first antenna group (1210) and third antenna group (1230)). The distance between two antenna groups (e.g., first antenna group (1210) and third antenna group (1230)) can be determined based on the folding angles between two adjacent housings (e.g., first folding angle (1311, 1321) and second folding angle (1312, 1322)).

[0254] According to one embodiment, the electronic device (1200) has a distance (e.g., D) between a first antenna group (1210) and a third antenna group (1230) corresponding to 0.04 of the first SPLSR condition. OPEN If a placement between multiple housings with a distance greater than ) is detected, it can be confirmed that the housing state is open state (1301).

[0255] According to one embodiment, the electronic device (1200) has a distance (e.g., D) between a first antenna group (1210) and a third antenna group (1230) corresponding to a specified value of a second SPLSR condition. CLOSE If a placement between multiple housings with a distance smaller than ) is detected, it can be confirmed that the state of the housing is closed (1302).

[0256] According to one embodiment, the electronic device (1200) has a distance (e.g., D) between a first antenna group (1210) and a third antenna group (1230) corresponding to 0.04 of the first SPLSR condition. OPEN The distance between the first antenna group (1210) and the third antenna group (1230) that is less than or equal to ) and corresponds to a specified value of the second SPLSR condition (e.g., D CLOSE It is possible to detect the arrangement between multiple housings where the distance between the first antenna group (1210) and the third antenna group (1230) is greater than or equal to ), and to confirm that the state of the housing is an intermediate state (1303).

[0257] The electronic device (1200) can calculate the SAR values ​​of antennas included in at least two antenna groups based on the confirmed housing condition, such that the sum of the SAR values ​​of the antennas included in at least two antenna groups satisfies the SAR standard. For example, the electronic device (1200) can calculate the SAR values ​​of the antennas included in the antenna groups based on an antenna group correlation coefficient matrix corresponding to the housing condition, corresponding to the housing condition.

[0258] The antenna group correlation matrix of an electronic device (1200) including three antenna groups may include an antenna group correlation matrix corresponding to an open state (1301), an antenna group correlation matrix corresponding to an intermediate state (1303), and / or an antenna group correlation matrix corresponding to a closed state (1302). For example, the antenna group correlation matrix may be expressed as [Equation 14].

[0259]

[0260] In [Equation 14], D i,j (θ1, θ2) may refer to the distance between the first antenna group (1210) and the third antenna group (1230).

When the state of the housing is closed (1302), the correlation coefficients included in the antenna group correlation coefficient matrix may be set to 1 for the ratio in which the SAR value of at least one antenna included in the third antenna group (1230) is reflected in the SAR value of the first antenna group (1210) and for the ratio in which the SAR value of at least one antenna included in the first antenna group (1210) is reflected in the SAR value of the third antenna group (1230). The correlation coefficients included in the antenna group correlation coefficient matrix can be set to numbers between 0 and 1, such that when the housing state is in an intermediate state (1303), the ratio in which the SAR value of at least one antenna included in the third antenna group (1230) is reflected in the SAR value of the first antenna group (1210) and the ratio in which the SAR value of at least one antenna included in the first antenna group (1210) is reflected in the SAR value of the third antenna group (1230), respectively. For example, the antenna group correlation coefficient matrix of an electronic device (1200) including three antenna groups can be expressed as [Equation 15].

[0262]

[0263] In [Equation 15], θ1 may refer to the first folding angle and θ2 to the second folding angle. 1,5 (θ1, θ2), r 1,6 (θ1, θ2), r 3,1 (θ1, θ2) and r 3,2(θ1, θ2) may be a constant between 0 and 1 or a function value that changes according to the folding angle.

Some values ​​included in [Equation 15] (e.g., r 1,5 (θ1, θ2), r 1,6 (θ1, θ2), r 3,1 (θ1, θ2) and r 3,2 (θ1, θ2)) is written as a function of angles, but may have a fixed value. It should be understood that if the value included in [Equation 15] has a fixed value, it may be updated by the manufacturer of the electronic device.

For example, the electronic device (1200) calculates the SAR value of the antenna group (e.g., a first antenna group (1210), a second antenna group (1220), or a third antenna group (1230)) using the SAR budget (e.g., N in Equation 2). SAR target ) and the sum of the previously calculated (or previously measured) SAR values ​​of the antenna group during the SAR measurement cycle (e.g., of Equation 2 The difference value can be calculated as a value smaller than the difference value. The SAR value of the first antenna group is calculated based on the maximum allowable SAR value (1404) corresponding to the first SAR standard, the SAR value of the second antenna group is calculated based on the maximum allowable SAR value (1405) corresponding to the third SAR standard, and the SAR value of the third antenna group can be calculated based on the maximum allowable SAR value (1406) corresponding to the second SAR standard.

[0268] The electronic device (1200) can calculate the SAR value of each antenna included in a plurality of antenna groups so as to have the calculated SAR value of the antenna group (e.g., first antenna group (1210), second antenna group (1220), or third antenna group (1230)). According to one example, the electronic device (800) can determine the SAR value of the antenna group by multiplying the correlation coefficients included in the antenna group correlation coefficient matrix included in Equation 14 with the SAR value of each antenna included in the plurality of antenna groups, and can determine (or verify) the SAR of each antenna included in the plurality of antenna groups such that the verified SAR value is the same as the SAR value verified using Equation 2.

The electronic device (1200) may calculate the SAR values ​​of the third antenna (1221) and / or the fourth antenna (1222) such that, in the open state (1301), the intermediate state (1303), and / or the state of the housing in the intermediate state (1303), the sum of the SAR values ​​of the antennas included in the second antenna group (1220) (e.g., the third antenna (1221) and the fourth antenna (1222)) satisfies the SAR criterion.

[0270] The state of the housing may be open (1301) during the first period (1410). The electronic device (1200) may calculate the SAR values ​​of the antennas included in the antenna group such that, when the state of the housing is open (1301), the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criteria. The electronic device (1200) may control the antennas included in the individual antenna group to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0271] The electronic device (1200) can check the antenna group correlation coefficient matrix corresponding to the open state (1301) when the housing state is open state (1301), and calculate the SAR value of each antenna included in a plurality of antenna groups so that the antenna group satisfies the SAR criterion. For example, the SAR value (1411) of the first antenna group (1210) can be calculated as the sum of the SAR value of the first antenna (1211) and the SAR value of the second antenna (1212) according to the antenna group correlation coefficient matrix corresponding to the open state (1301) of Equation 15. The electronic device (1200) can calculate the SAR value of the first antenna (1211) and the SAR value of the second antenna (1212) so that the first antenna group (1210) satisfies the first SAR criterion. For example, the SAR value (1413) of the third antenna group (1230) can be calculated as the sum of the SAR value of the fifth antenna (1231) and the SAR value of the sixth antenna (1232) according to the antenna group correlation coefficient matrix corresponding to the open state (1301) of Equation 15. The electronic device (1200) can calculate the SAR value of the fifth antenna (1231) and the SAR value of the sixth antenna (1232) so that the third antenna group (1230) satisfies the second SAR criterion. For example, the SAR value (1412) of the second antenna group (1220) can be calculated as the sum of the SAR value of the third antenna (1221) and the SAR value of the fourth antenna (1222) according to the antenna group correlation coefficient matrix corresponding to the open state (1301) of Equation 15. The electronic device (1200) can calculate the SAR value of the third antenna (1221) and the SAR value of the fifth antenna (1222) so that the second antenna group (1220) satisfies the third SAR standard.

[0272] The state of the housing may be changed from an open state (1301) to an intermediate state (1303) and may remain in the intermediate state (1303) during a second period (1420). When the housing is in the intermediate state (1303), the electronic device (1200) may calculate the SAR values ​​of the antennas included in the first antenna group (1210) and the third antenna group (1230) such that the sum of the SAR values ​​of the antennas included in the first antenna group (1210) and the third antenna group (1230) satisfies the SAR criteria. The electronic device (1200) may control the antennas included in the first antenna group (1210) and the third antenna group (1230) to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0273] When the state of the housing is an intermediate state (1303), the electronic device (1200) can check the antenna group correlation coefficient matrix corresponding to the intermediate state (1303) and calculate the SAR value of each antenna included in the plurality of antenna groups so that the antenna groups satisfy the SAR criteria. For example, the SAR value (1421) of the first antenna group (1210) can be calculated as the sum of the sum (14211) of a part of the SAR value of the fifth antenna (1231) and a part of the SAR value of the sixth antenna (1232), and the sum (14210) of the SAR value of the first antenna (1211) and the SAR value of the second antenna (1212), according to the antenna group correlation coefficient matrix corresponding to the intermediate state (1303) of Equation 15. A portion of the SAR value of the fifth antenna (1231) is the ratio in which the SAR value of the fifth antenna (1231) is reflected in the SAR value of the first antenna group (1210) (e.g., r in Equation 15). 1,5 It may refer to the product of (θ1, θ2)) and the SAR value of the third antenna (1221). A portion of the SAR value of the sixth antenna (1232) is the ratio in which the SAR value of the sixth antenna (1232) is reflected in the SAR value of the first antenna group (1210) (e.g., r in Equation 15). 1,6It may refer to the product of (θ1, θ2)) and the SAR value of the sixth antenna (1232). For example, the SAR value (1423) of the third antenna group (1230) may be calculated as the sum of the sum (14231) of a portion of the SAR value of the first antenna (1211) and a portion of the SAR value of the second antenna (1212), and the sum (14230) of the SAR value of the fifth antenna (1231) and the SAR value of the sixth antenna (1232), according to the antenna group correlation coefficient matrix corresponding to the intermediate state (1303) of Equation 15. The portion of the SAR value of the first antenna (1211) is the ratio in which the SAR value of the first antenna (1211) is reflected in the SAR value of the third antenna group (1230) (e.g., r in Equation 15). 3,1 It may refer to the product of (θ1, θ2)) and the SAR value of the first antenna (1211). A portion of the SAR value of the second antenna (1212) is the ratio in which the SAR value of the second antenna (1212) is reflected in the SAR value of the third antenna group (1230) (e.g., r in Equation 15). 3,2 It may refer to the product of the SAR value of (θ1, θ2)) and the value of the second antenna (1212). For example, the SAR value (1422) of the second antenna group (1220) can be calculated as the sum of the SAR value of the third antenna (1221) and the SAR value of the fourth antenna (1222) according to the antenna group correlation coefficient matrix corresponding to the intermediate state (1303) of Equation 15. The electronic device (1200) can calculate the SAR value of the third antenna (1221) and the SAR value of the fourth antenna (1222) so that the second antenna group (1220) satisfies the third SAR standard.

[0274] The state of the housing may be changed from an intermediate state (1303) to a closed state (1302), and may remain in the closed state (1302) for a third period (1430). When the housing is in the closed state (1302), the electronic device (1200) can calculate the SAR values ​​of the antennas included in the antenna groups of the first antenna group (1210) and the third antenna group (1230) such that the sum of the SAR values ​​of the antennas included in the antenna groups of the first antenna group (1210) and the third antenna group (1230) satisfies the SAR criteria. The electronic device (1200) can control the antennas included in the first antenna group (1210) and the third antenna group (1230) to use transmission power corresponding to the calculated SAR values ​​of the antennas.

[0275] The electronic device (1200) can check the antenna group correlation coefficient matrix corresponding to the closed state (1302) when the housing state is the closed state (1302), and calculate the SAR value of each antenna included in the plurality of antenna groups so that the antenna groups satisfy the SAR criteria. For example, the SAR value (1431) of the first antenna group (1210) (or the SAR value (1433) of the third antenna group (1230)) can be calculated as the sum of the SAR values ​​of the antennas included in the first antenna group (1210) (e.g., the sum of the SAR value of the first antenna (1211) and the SAR value of the second antenna (1212)) (14310) and the sum of the SAR values ​​of the antennas included in the third antenna group (1230) (e.g., the sum of the SAR value of the fifth antenna (1231) and the SAR value of the sixth antenna (1232)) (14330), according to the antenna group correlation coefficient matrix corresponding to the closed state (1302) of Equation 15. The electronic device (1200) can calculate the SAR value of the first antenna (1211), the SAR value of the second antenna (1212), the SAR value of the fifth antenna (1231), and the SAR value of the sixth antenna (1232) so that the first antenna group (1210) (or the third antenna group (1230)) satisfies the first SAR criterion (or the second SAR criterion). For example, the SAR value (1432) of the second antenna group (1220) can be calculated as the sum of the SAR value of the third antenna (1221) and the SAR value of the fourth antenna (1222), according to the antenna group correlation coefficient matrix corresponding to the closed state (1302) of Equation 15. The electronic device (1200) can calculate the SAR value of the third antenna (1221) and the SAR value of the fourth antenna (1222) so that the second antenna group (1220) satisfies the third SAR standard.

Short-range wireless communication may refer to various communication methods that both the electronic device and / or the external device can support. For example, wireless communication may be Wi-Fi. Cellular wireless communication is a various communication method that both the electronic device and / or the external device can support, and may be one of various cellular communications including 4th generation cellular communication (long-term evolution) and 5th generation cellular communication (new radio).

However, the state of the housing may be set according to the arrangements between multiple housings corresponding to the SPLSR pre-measured by the manufacturer, and the electronic device may check the state of the housing based on the arrangement between multiple housings without checking the SPLSR. The arrangement between multiple housings may be set to a specific housing state (e.g., open state, closed state, or intermediate state) depending on whether it satisfies a first SPLSR condition and / or a second SPLSR condition. The first SPLSR condition may include a condition where the SPLSR is less than 0.04. The second SPLSR condition may refer to a condition in which, for a specified value of the second SPLSR condition that is 0.04 or greater and less than 1, the SPLSR is less than or equal to the specified value of the second SPLSR condition.

[0285] According to one embodiment, in operation 1530, the electronic device can determine, based on the state of the housing, a correlation coefficient including the ratio in which the SAR value of at least one antenna included in a plurality of antenna groups is reflected in the SAR value of a first antenna group and the ratio in which the SAR value of at least one antenna included in a plurality of antenna groups is reflected in the SAR value of a second antenna group.

[0286] According to one example, at least some of the arrangements among the plurality of housings may be set to an open state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two of the plurality of antenna groups satisfy a first SAR to peak location separation ratio (SPLSR) condition. When at least some of the housings among the plurality of housings are arranged such that at least two of the plurality of antenna groups satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be determined to be an open state.

[0287] According to one embodiment, the electronic device can detect the arrangement between a plurality of housings in which SPLSR is less than 0.04 and confirm that the state of the housing is open.

[0288] The electronic device can calculate the SAR values ​​of antennas included in an antenna group such that when the housing state is open, the sum of the SAR values ​​of the antennas included in the individual antenna group satisfies the SAR criterion. For example, when the housing state is open, the electronic device can calculate the SAR values ​​of the antennas included in the antenna group based on an antenna group correlation coefficient matrix corresponding to the open state.

[0289] The antenna group correlation coefficient matrix corresponding to the open state may be a matrix in which the correlation coefficient in which the SAR value of at least one antenna included in the second antenna groups is reflected in the SAR value of the first antenna group and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna groups is reflected in the SAR value of the second antenna group are each set to 0.

[0290] For example, at least some of the housings among the plurality of housings may be arranged such that at least two of the plurality of antenna groups do not satisfy the first SPLSR condition. If at least some of the housings among the plurality of housings are arranged such that at least two of the plurality of antenna groups do not satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be determined to be a closed state. Some of the arrangements of the plurality of housings may be set to a closed state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two of the plurality of antenna groups included in the electronic device do not satisfy the first SPLSR condition and the second SPLSR condition. If at least some of the housings among the plurality of housings are arranged such that at least two of the plurality of antenna groups do not satisfy the first SPLSR condition and the second SPLSR condition, the arrangement state of at least some of the housings may be determined to be a closed state.

[0291] The electronic device can calculate the SAR values ​​of antennas included in at least two antenna groups such that, when the housing is in a closed state, the sum of the SAR values ​​of antennas included in at least two antenna groups satisfies the SAR criterion. For example, when the housing is in a closed state, the electronic device can calculate the SAR values ​​of antennas included in antenna groups based on an antenna group correlation coefficient matrix corresponding to the closed state.

[0292] The antenna group correlation coefficient matrix corresponding to the closed state may be a matrix in which the correlation coefficient in which the SAR value of at least one antenna included in the second antenna groups is reflected in the SAR value of the first antenna group and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna groups is reflected in the SAR value of the second antenna group are each set to 1.

[0293] According to one embodiment, at least some of the arrangements among the plurality of housings may be set to an intermediate state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two of the plurality of antenna groups do not satisfy the first SPLSR condition. If at least some of the housings among the plurality of housings are arranged such that at least two of the plurality of antenna groups do not satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be determined to be an intermediate state.

[0294] According to one embodiment, some of the arrangements of a plurality of housings may be set to an intermediate state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two antenna groups among a plurality of antenna groups included in an electronic device do not satisfy the first SPLSR condition but satisfy the second SPLSR condition. If at least some of the housings among the plurality of housings are arranged such that they do not satisfy the first SPLSR condition but satisfy the second SPLSR condition, the state of at least some of the housings may be determined to be an intermediate state.

[0295] According to one embodiment, the arrangement between a plurality of housings in which at least two of the plurality of antenna groups included in the electronic device do not satisfy the first SPLSR condition but satisfy the second SPLSR condition can be set to an intermediate state. The electronic device can detect the arrangement between a plurality of housings in which the SPLSR is 0.04 or higher and the SPLSR is less than or equal to a specified value, and confirm that the state of the housing is an intermediate state.

[0296] The electronic device can calculate the SAR values ​​of antennas included in at least two antenna groups such that, when the housing state is an intermediate state, the sum of the SAR values ​​of antennas included in at least two antenna groups satisfies the SAR criterion. For example, when the housing state is an intermediate state, the electronic device can calculate the SAR values ​​of antennas included in antenna groups based on an antenna group correlation coefficient matrix corresponding to the intermediate state.

[0297] The antenna group correlation coefficient matrix corresponding to the intermediate state may be a matrix in which the ratio in which the SAR value of at least one antenna included in the second antenna groups is reflected in the SAR value of the first antenna group and the correlation coefficient in which the SAR value of at least one antenna included in the first antenna groups is reflected in the SAR value of the second antenna group are each set to numbers between 0 and 1.

[0298] The electronic device may be in the form of a foldable device composed of two housings. In the electronic device in the form of a foldable device composed of two housings, the distance between two antenna groups may increase as the folding angle between the two housings increases. As the distance between the two antenna groups increases, the SPLSR of the two antenna groups may decrease.

[0299] According to one embodiment, at least some of the housings among the plurality of housings may be arranged at a folding angle such that the first antenna group and the second antenna group satisfy the first SPLSR condition. When at least some of the housings among the plurality of housings are arranged at a folding angle such that the first antenna group and the second antenna group satisfy the first SPLSR condition, the arrangement state of at least some of the housings may be set to an open state. According to one embodiment, the arrangement between the plurality of housings such that the first antenna group and the second antenna group have a folding angle such that the first antenna group and the second antenna group satisfy the first SPLSR condition may be set to an open state. The electronic device has a folding angle (e.g., θ) corresponding to 0.04 of the first SPLSR condition. OPEN It can detect the arrangement between multiple housings with a folding angle greater than ) and confirm that the housing is in an open state.

[0300] According to one embodiment, some of the arrangements of a plurality of housings may be set to a closed state. For example, at least some of the housings among the plurality of housings may be arranged at a folding angle such that at least two antenna groups among a plurality of antenna groups included in the electronic device do not satisfy the first SPLSR condition and the second SPLSR condition. If at least some of the housings among the plurality of housings are arranged at an angle such that at least two antenna groups among the plurality of antenna groups do not satisfy the first SPLSR condition and the second SPLSR condition, the arrangement state of at least some of the housings may be determined to be a closed state. The electronic device has a folding angle (e.g., θ) corresponding to a specified value of the second SPLSR condition. CLOSE It is possible to detect the arrangement between multiple housings with a folding angle smaller than ) and confirm that the state of the housing is closed.

[0301] According to one embodiment, some of the arrangements of the plurality of housings may be set to an intermediate state. For example, at least some of the housings among the plurality of housings may be arranged such that at least two of the plurality of antenna groups included in the electronic device (800) do not satisfy the first SPLSR condition but satisfy the second SPLSR condition. When at least some of the housings among the plurality of housings are arranged such that they do not satisfy the first SPLSR condition but satisfy the second SPLSR condition, the state of at least some of the housings may be determined to be an intermediate state. The electronic device has a folding angle (e.g., θ) corresponding to the minimum value of the distance between the first antenna group and the second antenna group. OPEN A folding angle that is less than or equal to ) and corresponds to the specified value of the second SPLSR condition (e.g., θ CLOSE It is possible to detect the arrangement between multiple housings with a folding angle greater than or equal to ) and confirm that the state of the housing is an intermediate state.

[0302] An antenna group correlation coefficient matrix may include a plurality of antenna group correlation coefficient matrices corresponding to each of a plurality of intermediate states. An arrangement between a plurality of housings in which at least two of the plurality of antenna groups included in the electronic device do not satisfy the first SPLSR condition but satisfy the second SPLSR condition may be set as an intermediate state. The intermediate state may be divided into a plurality of intermediate states depending on whether the third SPLSR condition is satisfied. The third SPLSR condition may refer to a condition in which the SPLSR is less than or equal to the specified value of the third SPLSR condition for a specified value of the third SPLSR condition that is greater than 0.04 of the first SPLSR condition and less than the specified value of the second SPLSR condition. For example, the first intermediate state may refer to an intermediate state that satisfies the third SPLSR condition, and the second intermediate state may refer to an intermediate state that does not satisfy the third SPLSR condition.

[0303] According to one embodiment, the electronic device can calculate the SAR value of each of at least one antenna included in a plurality of antenna groups based on the correlation coefficient identified in operation 1540, such that the first antenna group satisfies the first SAR criterion and the second antenna group satisfies the second SAR criterion.

[0304] When the housing is in an open state, the electronic device checks the antenna group correlation coefficient matrix corresponding to the open state and can calculate the SAR value of each antenna included in a plurality of antenna groups so that the antenna group satisfies the SAR criterion. For example, the SAR value of the first antenna group can be calculated as the sum of the SAR value of the first antenna and the SAR value of the second antenna according to the antenna group correlation coefficient matrix corresponding to the open state of Equation 12. The electronic device can calculate the SAR value of the first antenna and the SAR value of the second antenna so that the first antenna group satisfies the first SAR criterion. For example, the SAR value of the second antenna group can be calculated as the sum of the SAR value of the third antenna and the SAR value of the fourth antenna according to the antenna group correlation coefficient matrix corresponding to the open state of Equation 12. The electronic device can calculate the SAR value of the third antenna and the SAR value of the fourth antenna so that the second antenna group satisfies the second SAR criterion.

[0305] When the state of the housing is an intermediate state, the electronic device checks the antenna group correlation coefficient matrix corresponding to the intermediate state and can calculate the SAR value of each antenna included in a plurality of antenna groups so that the antenna groups satisfy the SAR criteria. For example, the SAR value of the first antenna group can be calculated as the sum of a portion of the SAR value of the third antenna, a portion of the SAR value of the fourth antenna, the SAR value of the first antenna, and the SAR value of the second antenna, according to the antenna group correlation coefficient matrix corresponding to the intermediate state of Equation 12. The portion of the SAR value of the third antenna is the ratio in which the SAR value of the third antenna is reflected in the SAR value of the first antenna group (e.g., r in Equation 12). 1,3 (θ)) and the product of the SAR value of the third antenna can be referred to. A portion of the SAR value of the fourth antenna is the ratio in which the SAR value of the fourth antenna is reflected in the SAR value of the first antenna group (e.g., r in Equation 12). 1,4 (θ)) and the product of the SAR value of the fourth antenna can be referred to. For example, the SAR value of the second antenna group can be calculated as the sum of a portion of the SAR value of the first antenna, a portion of the SAR value of the second antenna, the SAR value of the third antenna, and the SAR value of the fourth antenna, according to the antenna group correlation coefficient matrix corresponding to the intermediate state of Equation 12. The portion of the SAR value of the first antenna is the ratio in which the SAR value of the first antenna is reflected in the SAR value of the second antenna group (e.g., r in Equation 12). 2,1 (θ)) and the product of the SAR value of the first antenna value may be referred to. A portion of the SAR value of the second antenna is the ratio in which the SAR value of the second antenna is reflected in the SAR value of the second antenna group (e.g., r in Equation 12). 2,2 (θ)) and the product of the SAR value of the second antenna value can be referred to.

[0306] When the housing is in a closed state, the electronic device checks the antenna group correlation coefficient matrix corresponding to the closed state and can calculate the SAR value of each antenna included in a plurality of antenna groups so that the antenna group satisfies the SAR criterion. For example, the SAR value of the first antenna group (or the SAR value of the second antenna group) can be calculated as the sum of the SAR value of the first antenna, the SAR value of the second antenna, the SAR value of the third antenna, and the SAR value of the fourth antenna according to the antenna group correlation coefficient matrix corresponding to the closed state of Equation 12. The electronic device can calculate the SAR value of the first antenna, the SAR value of the second antenna, the SAR value of the third antenna, and the SAR value of the fourth antenna so that the first antenna group (or the second antenna group) satisfies the first SAR criterion (or the second SAR criterion).

[0307] According to one embodiment, in operation 1550, the electronic device can transmit a signal to an external device with power allocated to at least one antenna included in a plurality of antenna groups in correspondence with the calculated SAR value.

[0308] The electronic device can determine the SAR value of an antenna group during the next SAR window by reflecting the SAR value of at least one antenna included in a plurality of antenna groups.
