[0026] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0027] With the continuous improvement and use of electronic devices, the 3GPP protocol standard stipulates that the radio frequency radiation dose (SAR) of electronic devices to human tissue during communication must be controlled within a certain range to avoid any impact on human health. The SAR value is directly related to the antenna's transmission power.
[0028] In related technologies, such as MTK platform devices, SAR power backoff is implemented strictly in accordance with 3GPP standards to ensure compliance. For different antennas operating in the same frequency band, power backoff is implemented uniformly based on the antenna with the highest transmit power. For example, if antennas ANT1, ANT2, ANT3, and ANT4 are operating and ANT1 has the highest transmit power, and 3GPP SAR limits require a 3dB power backoff, all antennas will follow ANT1's uniform 3dB power backoff.
[0029] However, this will cause antennas with originally low transmission power or low antenna efficiency to have more backed-off power, which to some extent affects the uplink communication quality working on the low-power or low-efficiency antennas.
[0030] In view of this, the embodiments of the present application provide a power adjustment method, device, electronic device, storage medium and program product. The method can determine whether there is a first antenna among the multiple transmitting antennas that does not meet the target radiation requirement when the number of transmitting antennas currently in operation on the electronic device is multiple; if the first antenna exists, the backoff power value corresponding to the first antenna is determined according to the target radiation requirement; the transmit power of the first antenna is backed off according to the backoff power value corresponding to the first antenna, so that the first antenna meets the target radiation requirement after the power backoff processing. In this way, corresponding power backoff can be performed on all the first antennas in the multiple transmitting antennas in operation, and non-first antennas can be power backoff differently. That is, each first antenna only needs to perform a minimum adaptive power backoff, thereby ensuring that the target radiation requirement is met while avoiding performance degradation of each transmitting antenna due to power backoff.
[0031] In an exemplary embodiment, Figure 1 As shown, a power adjustment method is provided, and the method is applied to an electronic device as an example for explanation. The electronic device may be a device provided with a transmitting antenna. Optionally, the electronic device may be a laptop computer, a smart phone, a tablet computer, an Internet of Things device, a portable wearable device, etc. The Internet of Things device may be a smart speaker, a smart TV, a smart air conditioner, a smart car device, a projection device, etc. The portable wearable device may be a smart watch, a smart bracelet, a head-mounted device, etc. The head-mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. Figure 1 As shown, the power adjustment method may include the following steps:
[0032] Step 101: When the electronic device currently has multiple transmitting antennas in operation, determine whether there is a first antenna among the multiple transmitting antennas that does not meet the target radiation requirement.
[0033] In an optional embodiment of the present application, the current communication mode of the electronic device may be determined first, and then the communication frequency band under the current communication mode may be determined, and then whether the number of transmitting antennas corresponding to the communication frequency band is multiple. The communication mode may be, for example, cellular communication, or may be WiFi (Wireless Fidelity), BT (Bluetooth), GPS (Global Positioning System) communication, etc., which are not fully exemplified here.
[0034] For example, the electronic device may first detect the current network status indicator of the electronic device to determine whether cellular communication is in progress. If cellular communication is in progress, the electronic device may then detect the current operating frequency band of the cellular communication to determine whether multiple transmitting antennas are present in the corresponding frequency band. The transmitting antennas are configured to radiate the transmitted signal into free space.
[0035] It is understandable that in some possible implementations, the transmitting antenna may also serve as a receiving antenna to receive signals in free space.
[0036] In an optional embodiment of the present application, the target radiation requirement specifies that the average radiation level of the transmitting antenna during a recent period of a preset duration must not exceed a preset value. The electronic device can detect the average radiation level of each transmitting antenna during the recent period of the preset duration to determine whether the target radiation requirement is met. For example, if the preset duration is 5 seconds, the recent period of the preset duration refers to the 5-second period that includes the current moment.
[0037] Optionally, the radiation amount is a SAR (Specific Absorption Rate) value.
[0038] It is understandable that the number of first antennas may be single or multiple, for example, there may be a case where all transmitting antennas are first antennas.
[0039] Step 102: If the first antenna exists, determine the back-off power value corresponding to the first antenna according to the target radiation requirement.
[0040] In an optional embodiment of the present application, as mentioned above, the target radiation requirement stipulates that the average radiation of the transmitting antenna when it is operating within a period of a recent preset time length cannot be greater than a preset value, and the electronic device also detects the average radiation of each first antenna when it is operating within a period of a recent preset time length, and the detection is determined based on the transmission power of the first antenna when it is operating within the period of the recent preset time length. Therefore, it can be determined that the average radiation of each first antenna in the next preset time length is reduced to the transmission power value required to fall back within the above-mentioned preset value, thereby obtaining the fallback power value corresponding to the first antenna.
[0041] The target radiation requirement and the above-mentioned preset value specified therein may be pre-stored in the electronic device.
[0042] If there are multiple antennas, the back-off power values of the first antennas may be different.
[0043] Step 103 : performing a backoff process on the transmit power of the first antenna according to the backoff power value corresponding to the first antenna, so that the first antenna meets the target radiation requirement after the power backoff process.
[0044] For example, if the power back-off value corresponding to the first antenna 1 is 1 dB, the current transmit power of the first antenna is reduced by 1 dB.
[0045] After the power backoff process, the average radiation amount of the first antenna in the next preset time period is reduced to meet the target radiation amount requirement.
[0046] The power adjustment method, when the electronic device currently has multiple transmitting antennas in operation, determines whether there is a first antenna among the multiple transmitting antennas that does not meet the target radiation requirement; if there is a first antenna, determines a corresponding backoff power value for the first antenna based on the target radiation requirement; and performs backoff processing on the transmit power of the first antenna based on the backoff power value corresponding to the first antenna, so that the first antenna meets the target radiation requirement after the power backoff processing. In this way, corresponding power backoff can be performed on all first antennas in the multiple transmitting antennas in operation, while non-first antennas can be subjected to different power backoffs. That is, each first antenna only needs to perform a minimum adaptive power backoff, thereby ensuring that the target radiation requirement is met while avoiding performance degradation of each transmitting antenna due to power backoff.
[0047] Please refer to Figure 2 In an optional embodiment of the present application, an optional technical process for determining whether the number of transmitting antennas is multiple is provided. The technical process may include the following steps:
[0048] Step 201: Determine the current communication frequency band of the electronic device.
[0049] Step 202: Determine whether there are multiple transmitting antennas operating in the current communication frequency band according to a preset frequency band antenna correspondence table.
[0050] The electronic device pre-stores a frequency band antenna correspondence table that contains the correspondence between different communication frequency bands and the number of transmit antennas. Optionally, if the electronic device includes a large number of antennas, the frequency band antenna correspondence table further includes information such as the identifier of the transmit antenna corresponding to each communication frequency band. This allows the electronic device to determine which transmit antennas are currently operating.
[0051] It is understood that the frequency band antenna mapping table includes the number of transmit antennas corresponding to different communication frequency bands corresponding to different communication modes. For example, the number of transmit antennas corresponding to various frequency bands corresponding to cellular communication, the number of transmit antennas corresponding to various frequency bands corresponding to WiFi communication, etc., which are not fully exemplified here.
[0052] In an optional embodiment of the present application, the operating frequency band corresponding to each antenna in the electronic device can be determined according to the radio frequency chain to which each antenna belongs during the design phase, thereby counting the number of transmitting antennas corresponding to each frequency band.
[0053] In this way, after the communication frequency band is detected, it is possible to quickly and efficiently determine whether there are multiple antennas.
[0054] In an exemplary embodiment, the target radiation requirement is used to indicate that the SAR value of the transmitting antenna within a preset time period must not be greater than the target SAR value.
[0055] That is, the SAR value of the transmitting antenna when operating within the most recent preset time period shall not be greater than the target SAR value.
[0056] The target radiation requirement is a preset protocol standard or a private protocol standard in the electronic device.
[0057] The preset protocol standard is, for example, the above-mentioned 3GPP protocol standard.
[0058] For example, the 3GPP protocol standard requires: SAR (Head & Body SAR) of the national standard (25mm, six planes): <2.0W / Kg. This means that when the head and body are within a distance of 25mm, the SAR values of the electronic device on all six planes (front, back, left, right, top, and bottom) do not exceed 2.0W / kg. For example, a private protocol standard for electronic devices requires: SAR (Head & Body SAR) of the national standard (25mm, six planes): <1.5W / Kg. This means that when the head and body are within a distance of 25mm, the SAR values of the electronic device on all six planes do not exceed 1.5W / kg.
[0059] In an optional embodiment of the present application, one of the protocol standard and the private protocol standard can be pre-selected as the target radiation requirement. The one with the more stringent SAR value limit of the two standards can be used as the target radiation requirement. For example, in the above example, the private protocol standard's limit of 1.5 W / kg is more stringent. In this case, the private protocol standard will be used as the target radiation requirement. That is, the average SAR value of the transmitting antenna during the most recent predetermined period of time cannot exceed 1.5 W / kg.
[0060] In this way, using stricter SAR standards as target radiation requirements can ensure that electronic devices are compliant in any usage scenario and minimize the user's actual radiation exposure.
[0061] Please refer to Figure 3 In an optional embodiment of the present application, an optional technical process for determining the first antenna is provided, which may include the following steps:
[0062] Step 301: Detect the current SAR value of each transmitting antenna.
[0063] That is, for each transmitting antenna, the average SAR value of the antenna in a historical period of a preset length including the current moment is detected to obtain the current SAR value of each transmitting antenna.
[0064] Step 302: Obtain a target SAR value specified by a target radiation requirement.
[0065] Taking the above as an example, if the target radiation requirement is the preset protocol standard, the target SAR value is 2.0W / kg; if the target radiation requirement is the private protocol standard, the target SAR value is 1.5W / kg.
[0066] Step 303: Determine the first antenna based on the comparison result between the current SAR value of each transmitting antenna and the target SAR value.
[0067] Exemplarily, according to the comparison results, the transmitting antenna whose current SAR value is greater than the target SAR value is used as the first antenna.
[0068] For example, the current frequency band is N41, and the corresponding transmitting antennas include antenna 1, antenna 2, antenna 3, and antenna 4. The detected current SAR value for antenna 1 is 2.5 W / kg, the current SAR value for antenna 2 is 2 W / kg, the current SAR value for antenna 3 is 1.5 W / kg, and the current SAR value for antenna 4 is 1 W / kg. However, the target radiation requirement is a more stringent private protocol standard, that is, a target SAR value of 1.5 W / kg. Therefore, the current SAR values of antennas 1 and 2 are greater than the target SAR value, while the current SAR values of antennas 3 and 4 are less than the target SAR value.
[0069] Therefore, antenna 1 and antenna 2 are used as the first antenna and need to be powered back off, while antenna 3 and antenna 4 do not need to be powered back off.
[0070] In an exemplary embodiment, determining the back-off power value corresponding to the first antenna according to the target radiation requirement includes: determining the back-off power value corresponding to each first antenna according to the current SAR value and the target SAR value of each first antenna.
[0071] In an optional implementation manner, the current SAR value and the target SAR value of each first antenna are converted into power values, and the back-off power values corresponding to each first antenna are determined according to the converted power values.
[0072] Please refer to Figure 4 In an optional embodiment of the present application, an optional technical process for determining a backoff power value corresponding to each first antenna based on the current SAR value and the target SAR value of each first antenna is provided. The technical process may include the following steps:
[0073] Step 401 : Perform power value conversion processing on the current SAR value of each first antenna to obtain a reference power value corresponding to each first antenna.
[0074] For example, taking the above antenna 1 and antenna 2 as the first antenna as an example, the reference power value of antenna 2 is: 2*10 3 mw=10*log(2*10 3 )dBm=33dBm. The reference power value of antenna 1 is calculated in the same way.
[0075] Step 402 : Subtract each reference power value from the target power value to obtain a backoff power value corresponding to each first antenna. The target power value is obtained by performing power value conversion processing on the target SAR value.
[0076] Since the target SAR value is predetermined, the target SAR value can be converted into a power value in advance to obtain the target power value and store it. Alternatively, the electronic device can calculate the target power value in real time. Similarly, the target power value is: 1.5*10 3 mw=10*log1.5*10 3 dBm≈32dBm.
[0077] Then, for antenna 2, the back-off power value = 33dBm - 32dBm = 1dB. The same calculation method can be used to calculate the back-off power value of antenna 1 to be 2.5dB.
[0078] In another optional implementation, the electronic device pre-stores a power backoff table containing the correspondence between the current SAR values of different antennas and the power backoff values. The power backoff table is queried based on the current SAR value of each first antenna to obtain the backoff power value corresponding to each first antenna.
[0079] In an embodiment of the present application, when there are multiple transmitting antennas when the electronic device is working, especially when the power of each transmitting antenna differs greatly or the antenna efficiency differs greatly, the power backoff value of each transmitting antenna is calculated separately, and the corresponding degree of power backoff is performed, so as to ensure that the low-power and low-efficiency antennas perform the minimum power backoff to the greatest extent, thereby improving the uplink communication quality.
[0080] In an exemplary embodiment, if the electronic device currently has a single transmitting antenna in operation, it can determine whether the single transmitting antenna meets the target radiation requirement, and if it does not meet the requirement, determine the backoff power value corresponding to the single antenna according to the target radiation requirement, and perform power backoff.
[0081] In one exemplary embodiment, the electronic device periodically detects the currently operating frequency band and, upon detecting a frequency band switch, determines whether there are multiple transmit antennas corresponding to the switched frequency band. Alternatively, upon detecting a frequency band switch, the electronic device triggers a program to detect the number of transmit antennas corresponding to the switched frequency band.
[0082] For ease of understanding, the power adjustment method is described below using a complete embodiment.
[0083] like Figure 5 As shown, during the operation of the electronic device, the network status of the electronic device is first detected to identify whether it is cellular communication or WIFI, BT or GPS communication. In the case of cellular communication, the current cellular operating frequency band of the electronic device is detected.
[0084] Determine whether there are multiple transmit antennas corresponding to the cellular operating frequency band. If there are multiple transmit antennas, perform power backoff based on the target radiation level requirement. Specifically, the target radiation level requirement is determined based on the more stringent SAR limit between the 3GPP standard and the electronic device proprietary protocol standard.
[0085] Taking the target radiation requirement as determined according to a private protocol standard and the operating frequency band as N41 as an example, the transmitting antennas set in the N41 frequency band include antenna 1, antenna 2, antenna 3, and antenna 4. When antenna 1 and antenna 2 exceed the target radiation requirement, only antenna 1 and antenna 2 are power-backed off. Antenna 3 and antenna 4 meet the target radiation requirement and do not need to be backed off. However, in the prior art, if antenna 1 and antenna 2 exceed the target radiation requirement and the current SAR value detected by antenna 1 is the largest, it is determined that antenna 1 needs to back off its power by 2.5dB based on the current SAR value detected by antenna 1. Then, the power of the four antennas is uniformly backed off by 2.5dB. Table 1 compares the power backoff of each antenna in the prior art and the present application solution:
[0086] Table 1
[0087]
[0088] It can be seen that compared with the existing technology, the present application performs adaptive power backoff processing on each antenna, which can ensure that low-power and low-efficiency antennas perform minimum power backoff to the greatest extent, thereby improving the uplink communication quality.
