[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0021] Because the transmission power of the antenna of the current electronic device cannot meet the requirements of SAR, a fallback mechanism is needed when the human body touches or is very close to the antenna of the electronic device to ensure that the human body is under a safe electromagnetic radiation power when approaching the device. At present, when the SAR control is triggered, the working power corresponding to each frequency band of the antenna will be backed off. In this way, when the electronic device has multiple antennas, if only one antenna triggers the SAR control, the working power of each antenna will be backed off. When the electronic device works in 4G eNB and 5G NR dual connection or dual uplink, it will affect the data uplink transmission rate. Therefore, it is necessary to identify the antenna that triggers SAR control and split the working frequency band of each antenna, so that the working power fallback can be triggered according to the respective antenna frequency bands. To this end, the embodiment of the present application provides an antenna working power adjustment method, which can be applied to the case where the electronic device has multiple antennas, such as Figure 1 As shown, the antenna operating power adjustment method includes:

[0022] S101 . In response to triggering SAR control, identifying a target detection channel that triggers SAR control.

[0023] In this embodiment, a sensor for identifying a human body is installed on the electronic device, such as a SAR sensor. Figure 2 The SAR sensor has two detection channels, CS0 and CS1, connected to antenna 1 and antenna 2, respectively. Antenna 1 has a corresponding operating frequency band list 1, and antenna 2 has a corresponding operating frequency band list 2, as shown in Table 1.

[0024] Table 1

[0025] Antenna Coding Operating frequency band Antenna 1 FR1 n1 Antenna 1 FR1 n3 Antenna 1 LTE Band 7 Antenna 1 FR1 n7 Antenna 1 LTE Band 38 Antenna 1 LTE Band 41 Antenna 1 FR1 n38 Antenna 1 FR1 n41 Antenna 1 FR1 n78 Antenna 2 GSM900 Antenna 2 WCDMA VIII Antenna 2 LTE Band 8 Antenna 2 FR1 n8 Antenna 2 GSM1800 Antenna 2 LTE Band 3 Antenna 2 WCDMA I Antenna 2 LTE Band 1 Antenna 2 LTE Band 34 Antenna 2 LTE Band 40 Antenna 2 FR1 n38 Antenna 2 FR1 n41

[0026] When a user approaches or touches antenna 1, the SAR sensor can receive a detection signal sent by the CS0 detection channel, thereby triggering SAR control. When a user approaches or touches antenna 2, the SAR sensor can receive a detection signal sent by the CS1 detection channel, thereby triggering SAR control. When a user touches both antenna 1 and antenna 2, the SAR sensor can receive detection signals sent by both the CS0 and CS1 detection channels, thereby triggering SAR control. Because the detection signal is sent to the SAR sensor via the detection channel, when SAR control is triggered, it is possible to identify which detection channel sent the detection signal to the SAR sensor, thereby determining the target detection channel that triggered SAR control. The number of target detection channels can be one or more.

[0027] In this embodiment, an electronic device having two antennas is used as an example for description, but the present invention is not limited thereto. The electronic device may have three antennas, four antennas, etc.

[0028] The target detection channel can be identified based on the unique identification, address, name and other information of the detection channel.

[0029] S102. Determine the target antenna connected to the target detection channel and the operating frequency band corresponding to the target antenna.

[0030] In this embodiment, since detection channels are associated with antennas in a one-to-one correspondence, a pre-established list of detection channel-antenna correspondences can be used. By querying this list, the target antenna associated with the target detection channel can be found. Since each antenna has a corresponding operating frequency band list, once a target antenna is found, its corresponding operating frequency band can be determined. This operating frequency band can include either a single operating frequency band or multiple operating frequency bands.

[0031] S103: Perform power backoff processing on the first working power of the working frequency band corresponding to the target antenna.

[0032] In this embodiment, each operating frequency band of each antenna is set with a corresponding first operating power, as shown in Table 2.

[0033] Table 2

[0034]

[0035]

[0036] After the target antenna and its corresponding operating frequency band are determined, the first operating power of the target antenna's corresponding operating frequency band can be backed off, reducing the power in the target antenna's operating frequency band to a safe electromagnetic radiation level for the human body and ensuring human safety. For antennas that have not yet been activated, the operating power of their corresponding operating frequency bands will not be reduced. Therefore, when a single antenna is operating, for example, when antenna 1 is operating and a user touches antenna 2, antenna 1 will not trigger SAR power reduction, and vice versa. When dual antennas are operating, for example, when an electronic device operates with 4G eNB and 5G NR dual connectivity or dual uplink, this means that both antennas 1 and 2 are operating simultaneously. However, if a person only approaches antenna 1, triggering SAR control, only the operating power of antenna 1's operating frequency band will be backed off, while the operating power of antenna 2's operating frequency band will remain unchanged. Similarly, when only approaching antenna 2, the operating power of antenna 2's operating frequency band will be backed off, while the operating power of antenna 1's operating frequency band will remain unchanged. Of course, if a person approaches both antennas 1 and 2 simultaneously, the operating power of both antennas 1 and 2 will be backed off.

[0037] The antenna working power adjustment method provided in the embodiment of the present application identifies the target detection channel that triggers SAR control in response to triggered SAR control; determines the target antenna connected to the target detection channel and the working frequency band corresponding to the target antenna; and performs power backoff processing on the first working power of the working frequency band corresponding to the target antenna; thereby, only the first working power of the target antenna that triggers SAR control can be subjected to power backoff processing, and the working power of other antennas on the electronic device will not be triggered to fall back. In this way, for multiple antennas or antennas that do not trigger SAR, their working power will not decrease, and unnecessary SAR control will not be caused, thus not affecting the data uplink transmission speed and improving the user experience.

[0038] In an optional embodiment, in step S101 , identifying the target detection channel that triggers SAR control includes: identifying the address of the detection channel that triggers SAR control; and determining the target detection channel that triggers SAR control according to the address of the detection channel.

[0039] Specifically, since the detection channel carries the address of the detection channel when sending the detection signal to the SAR sensor, the target detection channel that triggers the SAR control can be determined by identifying the address of the detection channel.

[0040] In this embodiment, by identifying the address of the detection channel that triggers the SAR control, due to the uniqueness of the detection channel address, the target detection channel that triggers the SAR control can be quickly and accurately determined according to the detection channel address.

[0041] In an optional embodiment, step S103 performs power backoff processing on the working power of the working frequency band corresponding to the target antenna, including: identifying the working state of the target antenna; and when it is determined that the working state of the target antenna is working, performing power backoff processing on the first working power of the working frequency band corresponding to the target antenna.

[0042] Specifically, the working state of the target antenna includes working and non-working. When the target antenna is working, it radiates signals outward through the target antenna. When the target antenna is non-working, the target antenna is in a resting state and does not radiate signals outward. When the user approaches or touches the target antenna, the target antenna may be in a working state or a non-working state. If the target antenna is in a non-working state, no signal is transmitted, and there is no electromagnetic radiation hazard when the user touches or approaches it. Therefore, the working state of the target antenna can be identified. If the working state of the target antenna is working, power backoff processing is performed on the first working power of the working frequency band corresponding to the target antenna. If the working state of the target antenna is non-working, no processing is required.

[0043] In one implementation, the operating status of the target antenna can be determined based on the strength of the signal radiated by the target antenna. If the signal radiated by the target antenna is strong or exceeds a certain threshold, the target antenna is in an operating state. If the signal radiated by the target antenna is weak, absent, or below a certain threshold, the target antenna is in an inoperative state.

[0044] In this embodiment, by identifying the working state of the target antenna, when it is determined that the working state of the target antenna is working, power backoff processing is performed on the first working power of the working frequency band corresponding to the target antenna, thereby reducing unnecessary power backoff processing.

[0045] In an optional embodiment, power backoff processing is performed on the working power of the working frequency band corresponding to the target antenna, including: determining the second working power of the working frequency band corresponding to the target antenna from a preset power configuration table according to the target antenna; adjusting the first working power of the working frequency band corresponding to the target antenna to the second working power, and the second working power of the working frequency band corresponding to the target antenna is less than the first working power.

[0046] Specifically, an operating power configuration table for each operating frequency band of antenna 1 and antenna 2 in different states may be pre-established, as shown in Table 3. The states may include: neither antenna 1 nor antenna 2 triggers SAR control (DSI0), antenna 1 triggers SAR control (DSI1), antenna 2 triggers SAR control (DSI2), and both antenna 1 and antenna 2 trigger SAR control (DSI3).

[0047] Table 3

[0048]

[0049]

[0050] After the target antenna and the operating frequency band corresponding to the target antenna are determined, the current state can be determined based on the target antenna. For example, when the target antenna is antenna 1, the current state is that antenna 1 triggers SAR control. The operating frequency bands of antenna 1 are: FR1 n1, FR1 n3, LTE Band 7, FR1 n7, LTE Band 38, LTE Band 41, FR1 n38, FR1 n41, and FR1 n78. Based on the current state, the second operating powers of the operating frequency bands corresponding to antenna 1 can be found in Table 3 as 20.0, 20.0, 18.0, 18.0, 21.0, 21.0, 19.0, 19.0, and 17.0, respectively. The first operating power corresponding to the operating frequency band of the first antenna can be adjusted to the second operating power. For example, the first operating powers of the operating frequency band of Antenna 1 (23.0, 23.0, 23.0, 23.0, 23.0, 23.0, 23.0, 23.0) are adjusted to 20.0, 20.0, 18.0, 18.0, 21.0, 21.0, 19.0, 19.0, and 17.0, respectively. This performs power backoff on the first operating power of the operating frequency band of Antenna 1. As shown in Table 3, the operating power of Antenna 2 remains the same as before Antenna 1 triggered SAR control.

[0051] In this embodiment, by pre-establishing a working power configuration table for each working frequency band of antenna 1 and antenna 2 in different states, the second working power of the working frequency band corresponding to the target antenna can be quickly determined from the preset power configuration table according to the target antenna, so that the first working power of the working frequency band corresponding to the target antenna can be quickly adjusted to the second working power, thereby realizing rapid power fallback processing of the first working power of the working frequency band corresponding to the target antenna.

[0052] The embodiment of the present application also provides an antenna working power adjustment device, which can be applied to the case where an electronic device has multiple antennas, such as Figure 3 As shown, the antenna working power adjustment device includes:

[0053] The identification unit 21 is used for identifying the target detection channel that triggers the SAR control in response to the triggering of the SAR control. The specific implementation method is described in step S101 of the above method embodiment, which will not be repeated here.

[0054] The determination unit 22 is used to determine the target antenna connected to the target detection channel and the operating frequency band corresponding to the target antenna; the specific implementation method is described in step S102 of the above method embodiment, which will not be repeated here.

[0055] The processing unit 23 is configured to perform power backoff processing on the first operating power of the operating frequency band corresponding to the target antenna. Detailed description of the implementation method is given in the description of step S103 of the above method embodiment, which will not be repeated here.

[0056] The antenna working power adjustment device provided in the embodiment of the present application identifies the target detection channel that triggers SAR control in response to triggered SAR control; determines the target antenna connected to the target detection channel and the working frequency band corresponding to the target antenna; and performs power backoff processing on the first working power of the working frequency band corresponding to the target antenna; thereby, only the first working power of the target antenna that triggers SAR control can be subjected to power backoff processing, and the working power of other antennas on the electronic device will not be triggered to fall back. In this way, for multiple antennas or antennas that do not trigger SAR, their working power will not decrease, and unnecessary SAR control will not be caused, thus not affecting the data uplink transmission speed and improving the user experience.

[0057] In an optional embodiment, the identification unit 21 includes: a first identification subunit, configured to identify the address of the detection channel that triggers SAR control; and a first determination subunit, configured to determine the target detection channel that triggers SAR control according to the address of the detection channel.

[0058] Specifically, since the detection channel carries the address of the detection channel when sending the detection signal to the SAR sensor, the target detection channel that triggers the SAR control can be determined by identifying the address of the detection channel.

[0059] In this embodiment, by identifying the address of the detection channel that triggers the SAR control, due to the uniqueness of the detection channel address, the target detection channel that triggers the SAR control can be quickly and accurately determined according to the detection channel address.

[0060] In an optional embodiment, the processing unit 23 includes: a second identification subunit, used to identify the working status of the target antenna; and a processing subunit, used to perform power backoff processing on the first working power of the working frequency band corresponding to the target antenna when it is determined that the working status of the target antenna is working.

[0061] Specifically, the working state of the target antenna includes working and non-working. When the target antenna is working, it radiates signals outward through the target antenna. When the target antenna is non-working, the target antenna is in a resting state and does not radiate signals outward. When the user approaches or touches the target antenna, the target antenna may be in a working state or a non-working state. If the target antenna is in a non-working state, no signal is transmitted, and there is no electromagnetic radiation hazard when the user touches or approaches it. Therefore, the working state of the target antenna can be identified. If the working state of the target antenna is working, power backoff processing is performed on the first working power of the working frequency band corresponding to the target antenna. If the working state of the target antenna is non-working, no processing is required.

[0062] In one implementation, the operating status of the target antenna can be determined based on the strength of the signal radiated by the target antenna. If the signal radiated by the target antenna is strong or exceeds a certain threshold, the target antenna is in an operating state. If the signal radiated by the target antenna is weak, absent, or below a certain threshold, the target antenna is in an inoperative state.

[0063] In this embodiment, by identifying the working state of the target antenna, when it is determined that the working state of the target antenna is working, power backoff processing is performed on the first working power of the working frequency band corresponding to the target antenna, thereby reducing unnecessary power backoff processing.

[0064] In an optional embodiment, the processing unit 23 includes: a second determination subunit, used to determine the second working power of the working frequency band corresponding to the target antenna from a preset power configuration table based on the target antenna; an adjustment subunit, used to adjust the first working power of the working frequency band corresponding to the target antenna to the second working power, and the second working power of the working frequency band corresponding to the target antenna is less than the first working power.

[0065] Specifically, an operating power configuration table for each operating frequency band of antenna 1 and antenna 2 in different states can be pre-established, as shown in Table 3 above. The states may include: neither antenna 1 nor antenna 2 triggers SAR control (DSI0), antenna 1 triggers SAR control (DSI1), antenna 2 triggers SAR control (DSI2), and both antenna 1 and antenna 2 trigger SAR control (DSI3).

[0066] After the target antenna and the operating frequency band corresponding to the target antenna are determined, the current state can be determined based on the target antenna. For example, when the target antenna is antenna 1, the current state is that antenna 1 triggers SAR control. The operating frequency bands of antenna 1 are: FR1 n1, FR1 n3, LTE Band 7, FR1 n7, LTE Band 38, LTE Band 41, FR1 n38, FR1 n41, and FR1 n78. Based on the current state, the second operating powers of the operating frequency bands corresponding to antenna 1 can be found in Table 3 as 20.0, 20.0, 18.0, 18.0, 21.0, 21.0, 19.0, 19.0, and 17.0, respectively. The first operating power corresponding to the operating frequency band of the first antenna can be adjusted to the second operating power. For example, the first operating powers of the operating frequency band of Antenna 1 (23.0, 23.0, 23.0, 23.0, 23.0, 23.0, 23.0, 23.0) are adjusted to 20.0, 20.0, 18.0, 18.0, 21.0, 21.0, 19.0, 19.0, and 17.0, respectively. This performs power backoff on the first operating power of the operating frequency band of Antenna 1. As shown in Table 3, the operating power of Antenna 2 remains the same as before Antenna 1 triggered SAR control.

[0067] In this embodiment, by pre-establishing a working power configuration table for each working frequency band of antenna 1 and antenna 2 in different states, the second working power of the working frequency band corresponding to the target antenna can be quickly determined from the preset power configuration table according to the target antenna, so that the first working power of the working frequency band corresponding to the target antenna can be quickly adjusted to the second working power, thereby realizing rapid power fallback processing of the first working power of the working frequency band corresponding to the target antenna.
