Abstract
Description
Electronic device for performing back-off operation of wireless signal, method of operation thereof, and recording medium
[0001] The present disclosure relates to an electronic device for performing a back-off operation of a wireless signal according to one embodiment, a method of operation thereof, and a recording medium.
[0002] Electronic devices containing communication modules are subject to a radio wave standard called the Specific Absorption Rate (SAR) to determine levels of electromagnetic waves harmful to the human body. While lowering the radio wave output (e.g., Tx power) can reduce harm to the human body by satisfying SAR standards, doing so may result in a deterioration of the electronic device's communication performance.
[0003] Accordingly, some electronic devices utilize grip sensors to reduce radio wave output only when the human body makes contact. This action of reducing radio wave output can be referred to as a back-off action (e.g., Tx power back-off). For instance, since radio waves are emitted through antennas, the antenna can be integrated into the grip sensor pad to detect contact only when a user touches it. The grip sensor can detect the presence of the human body by sensing a change in capacitance when a dielectric material is adjacent to the sensor pad and comparing this change in capacitance with a set threshold value.
[0004] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.

For example, the electronic device (101) may be a foldable device that is folded by the hinge structure (320). However, the electronic device (101) may be formed integrally without including a hinge structure. In FIG. 3, for example, the upper housing (301) may include an upper front housing (312) and an upper rear housing (311). For example, the lower housing (302) may include a lower front housing (313) and a lower rear housing (314). Other components of the electronic device (101) may be protected from the outside by housings (e.g., 311, 312, 313, 314). Some components of the electronic device (101) may be exposed to the outside through the housings (e.g., 311, 312, 313, 314) or through openings formed in the housings (e.g., 311, 312, 313, 314). According to one embodiment, referring to FIG. 3, the electronic device (101) may include an antenna (330) (e.g., antenna (230) of FIG. 2), and there is no limitation on the location where the antenna (330) (e.g., antenna (230) of FIG. 2) is placed. According to one embodiment, when the electronic device (101) is implemented in the form of a notebook (or laptop) as in FIG. 3 (or in the case of implementation in other forms of devices), the lower rear housing (314) of the electronic device (101) may be located near the user's body (e.g., knee or thigh) or may come into contact with the user's body.Additionally, when the electronic device (101) is held by a user, at least a portion of the housings (e.g., 311, 312, 313, 314) of the electronic device (101) may be located near or in contact with the user's body. In this case, compliance with the specific absorption rate (SAR) may be required due to electromagnetic waves emitted from the antennas (330) (e.g., 331, 332, 333, 334) included in the electronic device (101). One of the antennas (e.g., 331, 332, 333, 334) of FIG. 3 may be the first antenna (231). Another of the antennas (e.g., 331, 332, 333, 334) of FIG. 3 may be the second antenna (232).

[0054] According to one embodiment, FIG. 4 is a drawing for illustrating various examples of an electronic device (e.g., 101 of FIG. 1) comprising at least two housings and a flexible display.
[0055] According to one embodiment, an electronic device (e.g., 101 of FIG. 1) may include two or more housings, hinges connecting the two or more housings so as to be foldable, and a flexible display.
[0056] According to one embodiment, the flexible display is disposed on two or more housings and can be bent according to the rotational state of the housings. One side of each of the two or more housings is connected to a hinge, and the two or more housings can be rotated around the hinge.
[0057] According to one embodiment, two or more housing structures and a flexible display are provided in an electronic device (e.g., 101 of FIG. 1), and the electronic device (e.g., 101 of FIG. 1) can be formed in various forms depending on the rotational state of the housing structures. For example, as illustrated in FIG. 4, the various forms include a form that forms two regions in an electronic device (e.g., 101 in FIG. 1) (e.g., flexible display) (half fold (Fig. 4 (c))), a form that forms three regions in an electronic device (e.g., 101 in FIG. 1) (e.g., flexible display) (e.g., tri fold (Fig. 4 (a)), Z fold (Fig. 4 (b)), single open gate fold (Fig. 4 (f))), a form that forms four regions in an electronic device (e.g., 101 in FIG. 1) (e.g., double parallel reverse fold (Fig. 4 (d)), double parallel fold (Fig. 4 (e)), double gate fold (Fig. 4 (g)), roll fold (Fig. 4 (h)), accordion fold (Fig. 4 (i)), half fold then half fold (Fig. 4 (j))), and an electronic device (e.g., FIG. 1 101) (e.g., flexible display) may include a shape that forms more than a number of regions (e.g., half fold then tri fold ((k) of FIG. 4)). An electronic device (e.g., 101 of FIG. 1) includes housing structures and a flexible display connected to each other so as to be rotatable, and the housing structures may be rotated in such a shape. According to one embodiment, in the case of an electronic device (e.g., 101 of FIG. 1) comprising at least two housings and at least two displays disposed in each housing, each display of the electronic device (e.g., 101 of FIG. 1) may form an angle with respect to each other depending on the rotational state of the housings.
[0058] Meanwhile, although the electronic devices of FIG. 4 (e.g., 101 of FIG. 1) are described as having one display disposed on a plurality of housings, they may have different displays for each of the plurality of housings. Accordingly, the description of the electronic device (e.g., 101 of FIG. 1) and the method of operation thereof according to the various embodiments described below may also be applied to the description of an electronic device (e.g., 101 of FIG. 1) comprising at least two housings and at least two displays disposed in each housing.

[0061] FIG. 5 is a flowchart of a method for performing a back-off operation using a wireless signal according to one embodiment.
[0062] According to one embodiment, the electronic device (101) may perform a basic operation related to a wireless signal. The "basic operation" may include an operation of controlling a communication circuit (210) to maintain the output power of a signal output through an antenna (230) (e.g., a first antenna (231; 331; 332; 333; 334) and / or a second antenna (232; 331; 332; 333; 334)) within a set range. The electronic device (101) may perform a back-off operation related to a wireless signal. "Back-off operation" may include an operation to control the communication circuit (210) so that the output power of a signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) is reduced (e.g., reduced from the output power of the basic operation). For example, "back-off of output power" may be a reduction in output power, and / or a reduction in the limit value (or maximum value) of the output power. The output power of a signal output through an antenna (230) (e.g., a first antenna (231; 331; 332; 333; 334) and / or a second antenna (232; 331; 332; 333; 334)) can be controlled to a value less than or equal to a limit value (or, maximum value) of the output power. For example, the electronic device (101) can control the communication circuit (210) so that the output power of a signal output through an antenna (230) (e.g., a first antenna (231; 331; 332; 333; 334) and / or a second antenna (232; 331; 332; 333; 334)) is reduced by reducing the limit value (or, maximum value) of the output power.
[0063] At least some of the operations of FIG. 5 may be omitted. The order of the operations of FIG. 5 may be changed. Operations other than the operations of FIG. 5 may be performed before, during, or after the operations of FIG. 5.
[0064] Referring to FIG. 5, in operation 501, according to one embodiment, the electronic device (101) can check the characteristic value of a wireless signal. For example, the electronic device (101) can control the communication circuit (210) to transmit a signal through the first antenna (231; 331; 332; 333; 334). The electronic device (101) can receive a signal through the second antenna (232; 331; 332; 333; 334). For example, the signal received through the second antenna (232; 331; 332; 333; 334) can correspond to the signal transmitted through the first antenna (231; 331; 332; 333; 334). A signal transmitted through the first antenna (231; 331; 332; 333; 334) may include channel state information related to the wireless signal. The channel state information may include information for determining the time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal. For example, the electronic device (101) may determine the characteristic value of the wireless signal based on the signal received through the second antenna (232; 331; 332; 333; 334). The characteristic value of the wireless signal may include the time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal. The time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal may be determined based on the channel state information. For example, the electronic device (101) can check channel state information based on a signal received through the second antenna (232; 331; 332; 333; 334) and check characteristic values of the wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) based on the channel state information.
[0065] In operation 503, according to one embodiment, the electronic device (101) can determine whether a characteristic value of a wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) satisfies a first condition. For example, the first condition may include the time delay of the wireless signal exceeding a first threshold or the amount of change in amplitude of the wireless signal exceeding a second threshold. The characteristic value of the wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) may change depending on the change in permittivity around the electronic device (101). For example, the characteristic value of the wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) may change based on the movement of a user around the electronic device (101). For example, the time delay of the wireless signal may exceed the first threshold based on the movement of a user around the electronic device (101). The electronic device (101) can detect the movement of a user around the electronic device (101) based on the time delay of the wireless signal exceeding a first threshold value. For example, based on the movement of a user around the electronic device (101), the amount of change in the amplitude of the wireless signal may exceed a second threshold value. The electronic device (101) can detect the movement of a user around the electronic device (101) based on the amount of change in the amplitude of the wireless signal exceeding a second threshold value. The electronic device (101) can detect the movement of a user around the electronic device (101) based on the time delay of the wireless signal exceeding a first threshold value or the amount of change in the amplitude of the wireless signal exceeding a second threshold value. The electronic device (101) can determine that there is no movement of a user around the electronic device (101) based on the time delay of the wireless signal being below the first threshold value and the amount of change in the amplitude of the wireless signal being below the second threshold value. The electronic device (101) can determine the movement of a user around the electronic device (101) based on a wireless signal, based on a first condition.There are no restrictions on the method of setting criteria for determining the movement of a user around an electronic device (101) using the characteristic value of a wireless signal.
[0066] In operation 505, according to one embodiment, the electronic device (101) may perform a back-off operation related to the wireless signal based on the characteristic value of the wireless signal satisfying a first condition. For example, the electronic device (101) may control the communication circuit (210) so that the output power of the signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) is reduced (e.g., reduced from the output power of the basic operation) based on the characteristic value of the wireless signal satisfying the first condition. For example, the electronic device (101) can control the communication circuit (210) to reduce the output power of a signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) by reducing the limit value (or maximum value) of the output power based on the characteristic value of the wireless signal satisfying the first condition. The 505 operation can be understood as the electronic device (101) performing a back-off operation related to the wireless signal as it detects the movement of a user around the electronic device (101).
[0067] In operation 507, according to one embodiment, the electronic device (101) may perform a basic operation related to the wireless signal based on the fact that the characteristic value of the wireless signal does not satisfy the first condition. For example, the electronic device (101) may control the communication circuit (210) to maintain the output power of the signal output through the antenna (230) (e.g., the first antenna (231; 331; 332; 333; 334) and / or the second antenna (232; 331; 332; 333; 334)) within a set range based on the fact that the characteristic value of the wireless signal does not satisfy the first condition. Operation 507 can be understood as the electronic device (101) performing a basic operation related to the wireless signal as it determines that there is no movement of a user around the electronic device (101).

[0069] At least some of the operations of FIG. 6 may be omitted. The order of the operations of FIG. 6 may be changed. Operations other than those of FIG. 6 may be performed before, during, or after the operations of FIG. 6.
[0070] Referring to FIG. 6, in operation 601, according to one embodiment, the electronic device (101) can check the sensing value of the sensor (220). For example, the sensing value of the sensor (220) may include a value corresponding to the movement of the electronic device (101). The movement of the electronic device (101) may include, for example, left-right movement, forward-backward movement, up-down movement, and rotation of the electronic device (101). The electronic device (101) can use the sensor (220) to check a value corresponding to the movement of the electronic device (101) (e.g., movement along the X-axis, Y-axis, Z-axis, and / or rotation) (e.g., a change in the sensing value along the X-axis, a change in the sensing value along the Y-axis, a change in the sensing value along the Z-axis, and / or a change in the sensing value corresponding to rotation).
[0071] In operation 603, according to one embodiment, the electronic device (101) can determine whether the sensing value of the sensor (220) satisfies a second condition. For example, the electronic device (101) can determine whether a value corresponding to the movement of the electronic device (101) (e.g., movement along the X-axis, Y-axis, Z-axis, and / or rotation) (e.g., change in the sensing value along the X-axis, change in the sensing value along the Y-axis, change in the sensing value along the Z-axis, and / or change in the sensing value corresponding to rotation) satisfies the second condition. For example, the second condition may include the value corresponding to the movement of the electronic device (101) exceeding a first reference value (e.g., reference value in the X-axis direction, reference value in the Y-axis direction, reference value in the Z-axis direction, and / or reference value for rotation). For example, based on the movement of the electronic device (101), a value corresponding to the movement of the electronic device (101) (e.g., movement of the X-axis, Y-axis, Z-axis, and / or rotation) (e.g., change in the X-axis sensing value, change in the Y-axis sensing value, change in the Z-axis sensing value, and / or change in the sensing value corresponding to rotation) may change. For example, based on the movement of the electronic device (101) in the X-axis direction, the X-axis sensing value may change. The electronic device (101) may determine the movement of the electronic device (101) in the X-axis direction based on the change in the X-axis sensing value. The electronic device (101) may confirm that there is movement of the electronic device (101) in the X-axis direction based on the change in the X-axis sensing value exceeding a reference value in the X-axis direction. The electronic device (101) can determine that there is no movement in the X-axis direction of the electronic device (101) (e.g., that the range of movement is within a certain range) based on the change amount of the X-axis sensing value being less than or equal to a reference value in the X-axis direction. For example, the Y-axis sensing value may change based on the movement of the electronic device (101) in the Y-axis direction. The electronic device (101) can determine the movement of the electronic device (101) in the Y-axis direction based on the change amount of the Y-axis sensing value.The electronic device (101) can confirm that there is movement in the Y-axis direction of the electronic device (101) based on the change amount of the Y-axis sensing value exceeding the reference value in the Y-axis direction. The electronic device (101) can confirm that there is no movement in the Y-axis direction of the electronic device (101) (e.g., the range of movement is within a certain range) based on the change amount of the Y-axis sensing value being less than or equal to the reference value in the Y-axis direction. For example, the Z-axis sensing value may change based on the movement of the electronic device (101) in the Z-axis direction. The electronic device (101) can determine the movement in the Z-axis direction of the electronic device (101) based on the change amount of the Z-axis sensing value. The electronic device (101) can confirm that there is movement in the Z-axis direction of the electronic device (101) based on the change amount of the Z-axis sensing value exceeding the reference value in the Z-axis direction. The electronic device (101) can determine that there is no movement in the Z-axis direction of the electronic device (101) (e.g., that the range of movement is within a certain range) based on the change amount of the Z-axis sensing value being less than or equal to the reference value in the Z-axis direction. For example, based on the rotation of the electronic device (101), the sensing value corresponding to the rotation may change. The electronic device (101) can determine the rotation of the electronic device (101) based on the change amount of the sensing value corresponding to the rotation. The electronic device (101) can determine that there is rotation of the electronic device (101) based on the change amount of the sensing value corresponding to the rotation being greater than the reference value of the rotation. The electronic device (101) can determine that there is no rotation of the electronic device (101) based on the change amount of the sensing value corresponding to the rotation being less than or equal to the reference value of the rotation. The electronic device (101) can determine the movement of the electronic device (101) based on the second condition. The electronic device (101) can determine whether the electronic device (101) moved while the user is holding the electronic device (101) based on the second condition.There are no limitations on the method of setting criteria for determining the movement of the electronic device (101) using the sensing value of the sensor (220).
[0072] In operation 605, according to one embodiment, the electronic device (101) may perform a back-off operation related to a wireless signal based on the sensing value of the sensor (220) satisfying a second condition. For example, the electronic device (101) may control the communication circuit (210) so that the output power of the signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) is reduced (e.g., reduced from the output power of the basic operation) based on the sensing value of the sensor (220) satisfying the second condition. For example, the electronic device (101) may control the communication circuit (210) to reduce the output power of a signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) by reducing the limit value (or maximum value) of the output power based on the sensing value of the sensor (220) satisfying the second condition. The 605 operation can be understood as the electronic device (101) performing a back-off operation related to the wireless signal as it detects the movement of the electronic device (101).

A signal transmitted through the first antenna (231; 331; 332; 333; 334) may include channel state information related to the wireless signal. The channel state information may include information for determining the time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal. For example, the electronic device (101) may determine the characteristic value of the wireless signal based on the signal received through the second antenna (232; 331; 332; 333; 334). The characteristic value of the wireless signal may include the time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal. The time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal may be determined based on the channel state information.

[0080] In operation 709, according to one embodiment, the electronic device (101) can check the sensing value of the sensor (220) while the back-off operation is being performed. For example, the sensing value of the sensor (220) may include a value corresponding to the movement of the electronic device (101). The movement of the electronic device (101) may include, for example, left-right movement, forward-backward movement, up-down movement, and rotation of the electronic device (101). The electronic device (101) can use the sensor (220) to check a value corresponding to the movement of the electronic device (101) (e.g., movement along the X-axis, Y-axis, Z-axis, and / or rotation) (e.g., a change in the sensing value of the X-axis, a change in the sensing value of the Y-axis, a change in the sensing value of the Z-axis, and / or a change in the sensing value corresponding to rotation).

For example, the electronic device (101) can determine whether a value corresponding to the movement of the electronic device (101) (e.g., movement along the X-axis, Y-axis, Z-axis, and / or rotation) (e.g., change in the sensing value along the X-axis, change in the sensing value along the Y-axis, change in the sensing value along the Z-axis, and / or change in the sensing value corresponding to rotation) satisfies the second condition. For example, the second condition may include the value corresponding to the movement of the electronic device (101) exceeding a first reference value (e.g., reference value in the X-axis direction, reference value in the Y-axis direction, reference value in the Z-axis direction, and / or reference value for rotation). For example, based on the movement of the electronic device (101), a value corresponding to the movement of the electronic device (101) (e.g., movement of the X-axis, Y-axis, Z-axis, and / or rotation) (e.g., change in the X-axis sensing value, change in the Y-axis sensing value, change in the Z-axis sensing value, and / or change in the sensing value corresponding to rotation) may change. For example, based on the movement of the electronic device (101) in the X-axis direction, the X-axis sensing value may change.

For example, the Y-axis sensing value may change based on the movement of the electronic device (101) in the Y-axis direction. The electronic device (101) can determine the movement of the electronic device (101) in the Y-axis direction based on the change amount of the Y-axis sensing value.The electronic device (101) can confirm that there is movement in the Y-axis direction of the electronic device (101) based on the change amount of the Y-axis sensing value exceeding the reference value in the Y-axis direction. The electronic device (101) can confirm that there is no movement in the Y-axis direction of the electronic device (101) (e.g., the range of movement is within a certain range) based on the change amount of the Y-axis sensing value being less than or equal to the reference value in the Y-axis direction. For example, the Z-axis sensing value may change based on the movement of the electronic device (101) in the Z-axis direction. The electronic device (101) can determine the movement in the Z-axis direction of the electronic device (101) based on the change amount of the Z-axis sensing value. The electronic device (101) can confirm that there is movement in the Z-axis direction of the electronic device (101) based on the change amount of the Z-axis sensing value exceeding the reference value in the Z-axis direction. The electronic device (101) can determine that there is no movement in the Z-axis direction of the electronic device (101) (e.g., that the range of movement is within a certain range) based on the change amount of the Z-axis sensing value being less than or equal to the reference value in the Z-axis direction. For example, based on the rotation of the electronic device (101), the sensing value corresponding to the rotation may change. The electronic device (101) can determine the rotation of the electronic device (101) based on the change amount of the sensing value corresponding to the rotation. The electronic device (101) can determine that there is rotation of the electronic device (101) based on the change amount of the sensing value corresponding to the rotation being greater than the reference value of the rotation. The electronic device (101) can determine that there is no rotation of the electronic device (101) based on the change amount of the sensing value corresponding to the rotation being less than or equal to the reference value of the rotation.

The electronic device (101) can determine whether the electronic device (101) moved while the user is holding the electronic device (101) based on the second condition.There are no limitations on the method of setting criteria for determining the movement of the electronic device (101) using the sensing value of the sensor (220).
[0082] In operation 713, according to one embodiment, the electronic device (101) may maintain a back-off operation related to a wireless signal based on the sensing value of the sensor (220) satisfying a second condition. For example, the electronic device (101) may control the communication circuit (210) so that the output power of the signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) is maintained in a reduced state (e.g., to maintain a reduced state compared to the output power of the basic operation) based on the sensing value of the sensor (220) satisfying the second condition. For example, the electronic device (101) can control the communication circuit (210) to maintain the output power of a signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) in a reduced state by maintaining the limit value (or maximum value) of the output power in a reduced state based on the sensing value of the sensor (220) satisfying the second condition. The 713 operation can be understood as maintaining a back-off operation related to the wireless signal as the electronic device (101) detects the movement of the electronic device (101).
[0083] In operation 715, according to one embodiment, the electronic device (101) may release the back-off operation and perform basic operations related to the wireless signal based on the fact that the sensing value of the sensor (220) does not satisfy the second condition. For example, the electronic device (101) may control the communication circuit (210) to maintain the output power of the signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) within a set range based on the fact that the sensing value of the sensor (220) does not satisfy the second condition.

[0085] At least some of the operations of FIG. 8 may be omitted. The order of the operations of FIG. 8 may be changed. Operations other than those of FIG. 8 may be performed before, during, or after the operations of FIG. 8.
[0086] Referring to FIG. 8, in operation 801, according to one embodiment, the electronic device (101) can check the characteristic value of a wireless signal. For example, the electronic device (101) can control the communication circuit (210) to transmit a signal through the first antenna (231; 331; 332; 333; 334). The electronic device (101) can receive a signal through the second antenna (232; 331; 332; 333; 334). For example, the signal received through the second antenna (232; 331; 332; 333; 334) can correspond to the signal transmitted through the first antenna (231; 331; 332; 333; 334). A signal transmitted through the first antenna (231; 331; 332; 333; 334) may include channel state information related to the wireless signal. The channel state information may include information for determining the time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal. For example, the electronic device (101) may determine the characteristic value of the wireless signal based on the signal received through the second antenna (232; 331; 332; 333; 334). The characteristic value of the wireless signal may include the time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal. The time delay of the wireless signal and / or the amount of change in the amplitude of the wireless signal may be determined based on the channel state information. For example, the electronic device (101) can check channel state information based on a signal received through the second antenna (232; 331; 332; 333; 334) and check characteristic values of the wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) based on the channel state information.
[0087] In operation 803, according to one embodiment, the electronic device (101) can determine whether a characteristic value of a wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) satisfies a first condition. For example, the first condition may include the time delay of the wireless signal exceeding a first threshold or the amount of change in amplitude of the wireless signal exceeding a second threshold. For example, the characteristic value of the wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) may change based on the movement of a user around the electronic device (101). For example, the time delay of the wireless signal may exceed the first threshold based on the movement of a user around the electronic device (101). The electronic device (101) can determine the movement of a user around the electronic device (101) based on the time delay of the wireless signal exceeding the first threshold. For example, based on the movement of a user around the electronic device (101), the amount of change in the amplitude of the wireless signal may exceed a second threshold value. The electronic device (101) can detect the movement of a user around the electronic device (101) based on the amount of change in the amplitude of the wireless signal exceeding the second threshold value. The electronic device (101) can detect the movement of a user around the electronic device (101) based on the time delay of the wireless signal exceeding a first threshold value or the amount of change in the amplitude of the wireless signal exceeding the second threshold value. The electronic device (101) can determine that there is no movement of a user around the electronic device (101) based on the time delay of the wireless signal being below the first threshold value and the amount of change in the amplitude of the wireless signal being below the second threshold value. The electronic device (101) can determine the movement of a user around the electronic device (101) based on the wireless signal based on the first condition. There are no limitations on the method of setting criteria for determining the movement of a user around the electronic device (101) using characteristic values of the wireless signal.
[0088] In operation 805, according to one embodiment, the electronic device (101) may perform a back-off operation related to the wireless signal based on the characteristic value of the wireless signal satisfying a first condition. For example, the electronic device (101) may control the communication circuit (210) so that the output power of the signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) is reduced (e.g., reduced from the output power of the basic operation) based on the characteristic value of the wireless signal satisfying the first condition. For example, the electronic device (101) can control the communication circuit (210) so that the output power of a signal output through the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) is reduced by reducing the limit value (or, maximum value) of the output power based on the characteristic value of the wireless signal satisfying the first condition. The 805 operation can be understood as the electronic device (101) performing a back-off operation related to the wireless signal as it detects the movement of a user around the electronic device (101).

For example, the electronic device (101) can determine the antenna to which the back-off operation is to be applied based on the position of the antenna. The antenna to which the back-off operation is to be applied can be described in detail with reference to FIGS. 9 to 14.
[0101] At least some of the operations of FIG. 9 may be omitted. The order of the operations of FIG. 9 may be changed. Operations other than those of FIG. 9 may be performed before, during, or after the operations of FIG. 9.
[0102] Referring to FIG. 9, in operation 901, according to one embodiment, the electronic device (101) can determine the location of the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)). For example, the "location (e.g., reference location)" of the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) may be a location related to compliance with the Specific Absorption Rate (SAR). For example, at a location within a range of 15 cm from the ground (or body), compliance with the radio wave standard for Specific Absorption Rate (SAR) may be required. In this case, the "location (e.g., reference location)" of the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) may include information regarding the distance from the ground (or body). However, the reference distance at which compliance with the radio wave standard for Specific Absorption Rate (SAR) is required may be set to a value other than 15 cm. According to one embodiment, the electronic device (101) can determine the position (e.g., reference position) of the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) based on the arrangement of the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) according to the design of the electronic device (101) and the state of the electronic device (101) (e.g., movement, horizontal, folding, mounting, and / or posture). According to one embodiment, the electronic device (101) can check the folding state of the electronic device (101) (e.g., whether it is folded or unfolded, and how many degrees the folding angle is).According to one embodiment, the electronic device (101) can check whether the electronic device (101) is mounted on a cradle (e.g., 1310 in FIG. 13). According to one embodiment, the electronic device (101) can check orientation information of the electronic device (101) (e.g., horizontal state, vertical state, and / or rotational state of the electronic device (101). Checking the horizontal state may include checking the angle that the reference plane of the electronic device (101) (e.g., the plane corresponding to the bottom rear housing (314) in FIG. 3) makes with the Z-axis. Checking the vertical state may include checking the angle that the reference plane of the electronic device (101) (e.g., the plane corresponding to the bottom rear housing (314) in FIG. 3) makes with the X-axis or Y-axis. Checking the rotational state may include checking the degree to which the electronic device (101) is tilted (e.g., the angle of tilt with respect to the X-axis, Y-axis, and / or Z-axis). For example, the electronic device (101) can identify a first position (e.g., a first reference position) of the first antenna (231; 331; 332; 333; 334) and a second position (e.g., a first reference position) of the second antenna (232; 331; 332; 333; 334).
[0103] In operation 903, according to one embodiment, the electronic device (101) can identify a target antenna based on the position (e.g., reference position) of the antenna (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)). The target antenna may be an antenna to which a back-off operation is applied. The target antenna may be an antenna to which a reference for the Specific Absorption Rate (SAR) is applied. For example, the electronic device (101) may identify an antenna among the antennas (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)) as a target antenna, the antenna whose location is included in a location where compliance with the electromagnetic absorption rate (SAR) radio wave standard is required. However, this is merely an example, and the electronic device (101) may identify the target antenna by a standard other than the electromagnetic absorption rate (SAR). There is no limit to the number of target antennas. According to one embodiment, based on the fact that there is no target antenna, the electronic device (101) may not perform a back-off operation even if a back-off operation is required.
[0104] In operation 905, according to one embodiment, the electronic device (101) may perform a back-off operation for an antenna identified as a target antenna among antennas (e.g., antennas (230) (e.g., first antennas (231; 331; 332; 333; 334) and / or second antennas (232; 331; 332; 333; 334)). If it is determined that the electronic device (101) will perform a back-off operation for the antenna identified as a target antenna, the electronic device (101) may perform a back-off operation for the antenna identified as a target antenna. For example, the electronic device (101) may have the output power of a signal output through the antenna identified as a target antenna among antennas (e.g., antennas (230) (e.g., first antennas (231; 331; 332; 333; 334) and / or second antennas (232; 331; 332; 333; 334)) The communication circuit (210) can be controlled to reduce (e.g., reduce the output power of the basic operation). For example, the electronic device (101) can control the communication circuit (210) so that the output power of the signal output through the antenna identified as the target antenna is reduced by reducing the limit value (or maximum value) of the output power of the signal output through the antenna identified as the target antenna among the antennas (e.g., antennas (230) (e.g., first antenna (231; 331; 332; 333; 334) and / or second antenna (232; 331; 332; 333; 334)).
[0105] With reference to FIGS. 10 to 14, the embodiments of FIGS. 2 to 9 can be described in detail. The embodiments of FIGS. 2 to 9 may be applied to the embodiments of FIGS. 10 to 14.
[0106] FIG. 10 is a drawing illustrating the operation of an electronic device (101) according to one embodiment.
[0107] In FIG. 10, the electronic device (101) may be in a folded state at a specific angle. FIG. 10 (a) may be a view of the electronic device (101) from the right. FIG. 10 (b) may be a view of the electronic device (101) from the top. For example, the bottom housing (302) of the electronic device (101) in FIG. 10 may be in a state horizontal to the ground, a state close to horizontal to the ground, or a state tilted at a certain angle from the state horizontal to the ground. For example, in FIG. 10, the first antenna (231) of the electronic device (101) may be placed in an area corresponding to the left side of the bottom housing (302) (e.g., an area corresponding to the left side of the bottom rear housing (314) in FIG. 3). For example, in FIG. 10, the second antenna (232) of the electronic device (101) may be placed in an area corresponding to the right side of the bottom housing (302) (e.g., an area corresponding to the right side of the bottom rear housing (314) in FIG. 3).
[0108] According to one embodiment, in FIG. 10, the electronic device (101) may perform a back-off operation, maintain a back-off operation, or release a back-off operation based on the embodiments of FIGS. 2 through 9. For example, in FIG. 10, the electronic device (101) may perform a back-off operation of the wireless signal or perform a basic operation of the wireless signal based on whether a characteristic value of the wireless signal (e.g., time delay of the wireless signal and / or amount of change in amplitude of the wireless signal) satisfies a first condition. For example, in FIG. 10, the electronic device (101) may perform a back-off operation of the wireless signal or perform a basic operation of the wireless signal based on whether a sensing value of the sensor (220) (e.g., a value corresponding to the movement of the electronic device (101)) satisfies a second condition. For example, in FIG. 10, the electronic device (101) checks the sensing value of the sensor (220) (e.g., a value corresponding to the movement of the electronic device (101)) while the back-off operation is performed based on a first condition, and based on whether the sensing value of the sensor (220) satisfies a second condition, it may maintain the back-off operation of the wireless signal or release the back-off operation and perform the basic operation of the wireless signal. For example, in FIG. 10, the electronic device (101) checks the sensing value of the sensor (220) (e.g., a value corresponding to the horizontal of the electronic device (101)) while the back-off operation is performed based on a second condition, and based on whether the sensing value of the sensor (220) satisfies a third condition, it may maintain the back-off operation of the wireless signal or release the back-off operation and perform the basic operation of the wireless signal. For example, in FIG. 10, the electronic device (101) can determine the location of the antenna (e.g., first antenna (231) and / or second antenna (232)).For example, the electronic device (101) can determine the position of an antenna (e.g., a first antenna (231) and / or a second antenna (232)) based on a folding state (e.g., whether it is folded or unfolded, and how many degrees the folding angle is) and orientation information (e.g., the horizontal state, vertical state, and / or rotational state of the electronic device (101)). The electronic device (101) can determine the first antenna (231) and the second antenna (232) as target antennas based on the position of the antennas (e.g., the first antenna (231) and / or the second antenna (232)). The electronic device (101) can perform a back-off operation of a wireless signal, maintain a back-off operation, or release a back-off operation for the target antennas (e.g., the first antenna (231) and the second antenna (232)) based on a first condition, a second condition, and / or a third condition.
[0109] FIG. 11 is a drawing illustrating the operation of an electronic device (101) according to one embodiment.
[0110] In FIG. 11, the electronic device (101) may be in an unfolded state. FIG. 11 (a) may be a view of the electronic device (101) from the right. FIG. 11 (b) may be a view of the electronic device (101) from the top. For example, the electronic device (101) in FIG. 11 may be in a state horizontal to the ground, a state close to horizontal to the ground, or a state tilted at a certain angle from the state horizontal to the ground. For example, FIG. 11 may be a situation in which the electronic device (101) is unfolded and the display of the electronic device (101) is viewed together with another person. For example, in FIG. 11, the first antenna (231) of the electronic device (101) may be placed in an area corresponding to the left side of the bottom housing (302) (e.g., an area corresponding to the left side of the bottom rear housing (314) in FIG. 3). For example, in FIG. 11, the second antenna (232) of the electronic device (101) may be placed in an area corresponding to the right side of the bottom housing (302) (e.g., an area corresponding to the right side of the bottom rear housing (314) in FIG. 3).
[0111] According to one embodiment, in FIG. 11, the electronic device (101) can perform a back-off operation of a wireless signal for a target antenna (e.g., a first antenna (231) and a second antenna (232)) based on the folding state of the electronic device (101) changing to an unfolded state (e.g., an unfolding operation). While the back-off operation is performed based on the unfolding operation, the electronic device (101) can determine whether the electronic device (101) is moving (e.g., a second condition) and whether the electronic device (101) is maintaining a horizontal position (e.g., a third condition) based on the sensing value of the sensor (220). The electronic device (101) can release the back-off operation for the target antenna (e.g., first antenna (231) and second antenna (232)) based on the fact that, after the back-off operation is performed based on the unfolding operation, the sensing value of the sensor (220) does not satisfy the second condition (e.g., the range of movement is within a certain range) and the sensing value of the sensor (220) does not satisfy the third condition (e.g., maintaining horizontal).
[0112] FIG. 12 is a drawing illustrating the operation of an electronic device (101) according to one embodiment.
[0113] In FIG. 12, the electronic device (101) may be in an unfolded state, standing vertically to the ground, or standing while maintaining a specific angle with respect to the ground. In FIG. 12, the first antenna (231) of the electronic device (101) may be positioned in an area corresponding to the left side of the bottom housing (302) (e.g., an area corresponding to the left side of the bottom rear housing (314) in FIG. 3). In FIG. 12, the second antenna (232) of the electronic device (101) may be positioned in an area corresponding to the right side of the bottom housing (302) (e.g., an area corresponding to the right side of the bottom rear housing (314) in FIG. 3). FIG. 12 may be in a state where the first antenna (231) is away from the ground and the second antenna (232) is close to the ground. FIG. 12 (a) may be a side view of the electronic device (101). Figure 12(b) may be a front view of the electronic device (101). For example, Figure 12 may be a situation in which the electronic device (101) is unfolded, the electronic device (101) is turned up and rotated 90 degrees, and the display of the electronic device (101) is viewed.
[0114] According to one embodiment, in FIG. 12, the electronic device (101) can perform a back-off operation of a wireless signal for the first antenna (231) and the second antenna (232) based on the rotation of the electronic device (101) (e.g., the electronic device (101) rotates to the state of FIG. 12) while the electronic device (101) is in an unfolded and upright state. Subsequently, while the back-off operation is being performed based on the rotation of the electronic device (101) (e.g., the electronic device (101) rotates to the state of FIG. 12), the electronic device (101) can determine whether movement and / or rotation of the electronic device (101) occurs based on the sensing value of the sensor (220). After the electronic device (101) performs a back-off operation based on the electronic device (101) rotating (e.g., the electronic device (101) rotates to become the state of FIG. 12), the back-off operation for the first antenna (231) located at the top relative to the ground is released, and the back-off operation for the second antenna (232) located at the bottom relative to the ground is maintained, based on confirming that there is no movement and / or rotation of the electronic device (101) or that it is maintained within a certain range by maintaining the sensing value of the sensor (220). Afterwards, the electronic device (101) may also release the back-off operation for the second antenna (232) located at the bottom relative to the ground based on the sensing value of the sensor (220).
[0115] FIG. 13 is a drawing illustrating the operation of an electronic device (101) according to one embodiment.
[0116] In FIG. 13, the electronic device (101) can maintain a specific angle with respect to the ground by being mounted on a cradle (1310) in an unfolded state. FIG. 13 (a) may be a side view of the electronic device (101). FIG. 13 (b) may be a front view of the electronic device (101). In FIG. 13, the first antenna (231) may be located at the top relative to the ground, and the second antenna (232) may be located at the bottom relative to the ground.
[0117] Referring to FIGS. 12 and 13, according to one embodiment, the electronic device (101) can perform a back-off operation of a wireless signal for the first antenna (231) and the second antenna (232) based on the electronic device (101) rotating in an unfolded state (e.g., the electronic device (101) rotates to become the state of FIG. 12). Afterward, the electronic device (101) can confirm that the electronic device (101) is mounted on the cradle (1310). For example, the electronic device (101) can confirm that the electronic device (101) is mounted on the cradle (1310) based on the movement and / or rotation state of the electronic device (101). For example, the electronic device (101) can determine that the electronic device (101) is mounted on the cradle (1310) based on determining the pogo voltage between the electronic device (101) and the cradle (1310) (e.g., a voltage determined through the connector of the electronic device (101) (e.g., a portion including a metal object that allows the electronic device (101) and the cradle (1310) to be electrically connected) as the electronic device (101) is mounted on the cradle (1310). The electronic device (101) can determine the positions of the first antenna (231) and the second antenna (232) based on determining that the electronic device (101) is mounted on the cradle (1310). The electronic device (101) can determine the second antenna (232), which is located at the bottom relative to the ground, as the target antenna while the electronic device (101) is mounted on the cradle (1310). Accordingly, the electronic device (101) can release the back-off operation for the first antenna (231), which is located at the top relative to the ground, based on the electronic device (101) being mounted on the cradle (1310), after the back-off operation is performed based on rotation (e.g., the electronic device (101) rotates to become the state of FIG. 12).Afterward, the electronic device (101) can release the back-off operation for the second antenna (232) located relatively lower to the ground based on confirming the communication connection between the electronic device (101) and the wireless keyboard (1320) while the electronic device (101) is mounted on the cradle (1310).
[0118] According to one embodiment, the electronic device (101) may disable the back-off operation for the first antenna (231) and / or the second antenna (232) based on verifying the communication connection between the electronic device (101) and the wireless keyboard (1320) while the back-off operation for the first antenna (231) and / or the second antenna (232) is being performed.
[0119] FIG. 14 is a drawing illustrating the operation of an electronic device (101) according to one embodiment.
[0120] Referring to FIG. 14, according to one embodiment, the electronic device (101) may be a multi-foldable device. FIG. 14 (a) may be a perspective view of the electronic device (101) in an unfolded state. FIG. 14 (b) may be a lower side view of the electronic device (101), in which the first housing (1410), the second housing (1420), and the third housing (1430) of the electronic device (101) are all unfolded, the third housing (1430) is folded, the first housing (1410) is folded, and the electronic device (101) is completely folded.
[0121] In FIG. 14, according to one embodiment, the electronic device (101) can determine the folding state of the electronic device (101) (e.g., whether the electronic device (101) is unfolded, which housing is folded, and what the folding angle is in degrees), and / or the orientation information of the electronic device (101) (e.g., horizontal state, vertical state, and rotational state). Based on the folding state and / or orientation information, the electronic device (101) can determine the first position of the first antenna (231) and the second position of the second antenna (232). Based on the first position of the first antenna (231) and the second position of the second antenna (232), the electronic device (101) can determine the target antenna. For the determined target antenna, the electronic device (101) can perform a back-off operation of the wireless signal, maintain the back-off operation, or release the back-off operation based on a first condition, a second condition, and / or a third condition.

The second condition may include the value corresponding to the movement of the electronic device (101) exceeding a first reference value. When the above instructions are executed individually or collectively by at least one processor (120), they may cause the electronic device (101) to release the back-off operation and perform the basic operation based on the fact that the sensing value does not satisfy the second condition.
[0127] According to one embodiment, when the instructions are executed individually or collectively by at least one processor (120), the electronic device (101) may be caused to maintain the back-off operation based on the sensing value satisfying a third condition while the back-off operation is performed by the sensing value satisfying the second condition.
