Fig. 1 schematically shows a flow chart of a specific absorption rate adjustment setting method according to an embodiment of the present application. The execution subject of the specific absorption rate adjustment setting method may be any device having communication capability, such as a television, a computer, a mobile phone, a smart watch, a home appliance, and the like.
As shown in fig. 1, the specific absorption rate adjustment setting method may include steps S110 to S140.
Step S110, determining antennas where each frequency band is located in a frequency band combination supported by a terminal, wherein the frequency band combination belongs to a frequency band combination set supported by the terminal; step S120, determining a measurement channel corresponding to the frequency band combination, wherein the measurement channel refers to the frequency band with the largest frequency in the frequency band combination; step S130, obtaining a measuring antenna corresponding to the frequency band combination according to the specific absorption rate value of the measuring channel on the antenna where each frequency band is located; and step S140, determining a single-frequency power limit value according to the measured frequency channel and the measured antenna corresponding to the frequency band combination, wherein the single-frequency power limit value is used for setting the single-frequency power limit value as the total power upper limit value when the terminal works under the frequency band combination.
The terminal supports a plurality of frequency band combinations, each frequency band combination can comprise a 4G frequency band and a 5G frequency band, and a set of the plurality of frequency band combinations supported by the terminal is a frequency band combination set.
For each frequency band combination supported by the terminal, according to the antenna design information in the terminal, the antenna where each frequency band is located in the frequency band combination supported by the terminal can be determined, the emission of each frequency band may or may not be on the same antenna (i.e. the antenna where each frequency band is located may be one or more), and the different antennas have different antenna designs due to different layouts and different environments on the mobile terminal, so that the generated radiation damage is different. For example, one band combination is endcb5+n2, where B5 is transmitted on the A1 antenna and N2 is transmitted on the A2 antenna, i.e. the 4G LTE band and the 5G NR band use two different antennas to transmit signals, where B5 refers to the 4G LTE band and N2 is the 5G NR band.
Further, for each frequency band combination supported by the terminal, a measurement channel corresponding to the frequency band combination may be determined, where the measurement channel refers to a frequency band with the largest frequency in the frequency band combination. Each communication frequency band generally has a certain bandwidth, that is, the frequency range supported by the frequency band is a range, the frequency range may include a plurality of frequency points and channels, and the frequency of which frequency band is higher may be compared according to the intermediate channel frequency point of each frequency band. For example, in the frequency band combination endcb5+n2, the frequency point of the middle channel of the transmitting segment of N2 is 1880Mhz, and the frequency point of the middle channel of the transmitting segment of B5 is 836.5Mhz, and as compared with the frequency point of the middle channel of the transmitting segment of N2, it is known that the frequency is higher, N2 can be used as the measurement frequency channel corresponding to the frequency band combination endcb5+n2.
The measured channel is the frequency band with the largest frequency in the channel combination, and the power of the channel combination is determined according to the measured channel, so that the specific absorption rate of the terminal when working with the channel combination can be reliably ensured to meet the related requirements.
Further, according to the specific absorption rate value of the measured channel on the antenna where each frequency band is located, a measured antenna corresponding to the frequency band combination can be obtained, for example, in the frequency band combination endcb5+n2, B5 is transmitted on the A1 antenna and N2 is transmitted on the A2 antenna, when the same conductive power is used, the specific absorption rate value 1 when the measured channel N2 works on the A1 antenna and the specific absorption rate value 2 when the measured channel N2 works on the A2 antenna can be tested, a comparison result can be obtained by comparing the specific absorption rate value 1 and the specific absorption rate value 2, and one of the A1 antenna or the A2 antenna can be determined as the measured antenna corresponding to the frequency band combination according to the comparison result.
Further, according to the measurement channel and the measurement antenna corresponding to the frequency band combination, a single-frequency power limit value is determined, the single-frequency power limit value can be set as a total power upper limit value when the terminal works under the frequency band combination, and the terminal can control the power of the terminal to be smaller than or equal to the total power upper limit value when the terminal works under the frequency band combination, so that the specific absorption rate generated in the terminal meets the specific absorption rate standard requirement, and meanwhile, the respective powers of two frequency bands in the frequency band combination are not excessively reduced.
For example, the total power upper limit value of the frequency band combination endcb5+n2 is limited to 20dBm, but the advantage is that the maximum power of the two frequency bands can be reached by both LTE B5 and NR N2, and the communication quality can be ensured even though the power of each frequency band is reduced less than the maximum power of the two frequency bands is limited by fixedly reducing the power of LTE B5 and NR N2. (for example, to achieve the same total power limit, the total power upper limit value of the frequency band combination ENDC B5+N2 of the previous method is 23dBm, however, the power of the LTE B5 and the NR N2 needs to be limited to be respectively not more than 17dBm, that is, the maximum power of each of the two frequency bands is not more than 17dBm. In the mode of the application, the total power upper limit value of the frequency band combination can be achieved by each of the LTE B5 and the NR N2, for example, one of the two frequency bands can reach the maximum 20dBm, and the power of the other frequency band is only low enough, for example, the power of-10 dBm).
And executing the steps for each frequency band combination supported by the terminal to obtain the total power upper limit value corresponding to each frequency band combination.
In this way, based on steps S110 to S140, the frequency band with the largest frequency in the frequency band combination is determined as the corresponding measurement channel, and the measurement antenna corresponding to the frequency band combination is obtained according to the specific absorption rate value of the measurement channel on the antenna where each frequency band is located, and the single-frequency power limit value is determined to be the total power upper limit value when the terminal works under the frequency band combination according to the measurement channel and the measurement antenna corresponding to the frequency band combination, so that the terminal can meet the specific absorption rate limit requirement when working based on the frequency band combination, meanwhile, the respective powers of the two frequency bands are reduced excessively, the specific absorption rate regulation setting reliability is improved, and the terminal communication quality is improved.
Further alternative embodiments of the steps performed when the specific absorption rate adjustment setting is performed under the embodiment of fig. 1 are described below.
In one embodiment, referring to fig. 2, the obtaining the measured antenna corresponding to the frequency band combination according to the specific absorption rate value of the measured frequency channel on the antenna where each frequency band is located may include:
step S210, determining the antenna corresponding to the maximum specific absorption rate value according to the specific absorption rate value of the measured channel on the antenna where each frequency band is located; step S210, obtaining a measuring antenna corresponding to the frequency band combination according to the antenna corresponding to the maximum specific absorption rate value.
And determining the antenna corresponding to the maximum specific absorption rate value according to the specific absorption rate value of the measured channel on the antenna where each frequency band is located. For example, in the frequency band combination endcb5+n2, B5 is transmitted on the A1 antenna, N2 is transmitted on the A2 antenna, and when the same conductive power is used, the specific absorption rate value 1 of the channel N2 when the A1 antenna is operated and the specific absorption rate value 2 of the channel N2 when the A2 antenna is operated can be measured, and the comparison result can be obtained by comparing the specific absorption rate value 1 with the specific absorption rate value 2; according to the comparison result, the largest one of the specific absorption rate value 1 and the specific absorption rate value 2 can be determined, and then the antenna corresponding to the largest specific absorption rate value is determined, for example, if the specific absorption rate value 1 is greater than the specific absorption rate value 2, the antenna corresponding to the largest specific absorption rate value 1 is the antenna corresponding to the A1.
Further, in this embodiment, according to the antenna corresponding to the maximum specific absorption rate value, the measurement antenna corresponding to the frequency band combination is obtained, and specifically, the antenna corresponding to the maximum specific absorption rate value may be used as the measurement antenna corresponding to the obtained frequency band combination. For example, the A1 antenna corresponding to the maximum specific absorption value 1 is used as the measurement antenna corresponding to the obtained frequency band combination endcb5+n2.
And obtaining a measuring antenna corresponding to the frequency band combination by using the antenna corresponding to the maximum specific absorption rate value under the measuring frequency band, and reliably determining the total power upper limit value adapted to the frequency band combination according to the measuring frequency band and the measuring antenna.
Further, in an embodiment, the obtaining the measurement antenna corresponding to the frequency band combination according to the specific absorption rate value of the measurement channel on the antenna where each frequency band is located may include:
obtaining a difference value between the specific absorption rate values according to the specific absorption rate values of the measured channels on the antenna where each frequency band is located; determining an antenna threshold corresponding to the terminal type and the antenna priority of the antenna where each frequency band is located under the terminal type according to the terminal type of the terminal; and if the difference value is smaller than the antenna threshold value, selecting the antenna corresponding to the highest antenna priority as the measuring antenna corresponding to the frequency band combination.
In this embodiment, according to the terminal type of the terminal, the antenna threshold corresponding to the terminal type and the antenna priority of the antenna where each frequency band is located under the terminal type may be queried and determined from the preset type threshold priority mapping table.
The difference between the specific absorption rate values is obtained according to the specific absorption rate values of the measured channels on the antenna where the frequency bands are located, for example, the specific absorption rate value 1 of the measured channel N2 when the antenna A1 works and the specific absorption rate value 2 of the measured channel N2 when the antenna A2 works can be obtained, and the difference between the specific absorption rate value 1 and the specific absorption rate value 2 can be obtained by comparing the specific absorption rate value 1 with the specific absorption rate value 2.
And if the difference is smaller than the antenna threshold, selecting the antenna corresponding to the highest antenna priority as the measuring antenna corresponding to the frequency band combination. For example, if the difference is smaller than the antenna threshold, but the antenna priority of the A2 antenna is higher than that of the A1 antenna, the A2 antenna may be used as the measurement antenna corresponding to the frequency band combination endcb5+n2.
Different terminal types can correspond to different antenna thresholds and antenna priorities of antennas corresponding to different frequency bands, the antenna thresholds and the antenna priorities can be pre-designated in a preset type threshold priority mapping table according to the terminal types, a determination antenna can be reliably determined according to the antenna priorities when the difference is smaller than the antenna thresholds, abnormal applicability of the terminal caused by directly taking the antenna corresponding to the maximum specific absorption rate value as the determination antenna is avoided, and furthermore, the reliability of setting the total power upper limit value for the frequency band combination supported by the terminal can be further improved based on the mode of the embodiment.
Further, the method may further include: and if the difference value is larger than the antenna threshold value, selecting the antenna corresponding to the maximum specific absorption rate value as a measuring antenna corresponding to the frequency band combination.
For example, if the difference is greater than the antenna threshold, the antenna priorities of the A2 antenna and the A2 antenna may be ignored, and the A1 antenna corresponding to the maximum specific absorption rate value 1 may be used as the measurement antenna corresponding to the obtained frequency band combination endcb5+n2.
In one embodiment, referring to fig. 3, the determining a single frequency power limit according to the measured frequency channel and the measured antenna corresponding to the frequency band combination may include: step S310, acquiring specific absorption rate data of the terminal when working based on different conductive powers under a measurement combination, wherein the measurement combination refers to a combination of the measurement channel and the measurement antenna; step S320, obtaining the single frequency power limit according to the maximum conduction power corresponding to the specific absorption rate data meeting the specific absorption rate limit requirement.
Through the test, specific absorption rate data (in particular specific absorption rate values) can be obtained when the terminal is operated with different conduction powers in a measurement combination (combination of measurement channel and measurement antenna). For example, the terminal may be fixed to operate in a measurement combination (combination of measurement channel and measurement antenna) to reduce the conducted power by 1dB each time from 23dbm, resulting in specific absorption rate data for operation at different conducted powers.
After the specific absorption rate data of the working under different conduction powers are obtained, the corresponding maximum conduction power in the specific absorption rate data meeting the specific absorption rate limiting requirement can be obtained. According to the conduction power, a single-frequency power limit value can be obtained and set as a total power upper limit value when the terminal works under the frequency band combination, so that the terminal can be effectively ensured to meet the specific absorption rate limit requirement when the terminal works based on the frequency band combination, and meanwhile, the respective powers of the two frequency bands are reduced excessively.
Further, in an embodiment, the obtaining the single frequency power limit according to the maximum conduction power corresponding to the specific absorption rate data meeting the specific absorption rate limit requirement includes one of the following manners:
firstly, taking the maximum conduction power corresponding to the specific absorption rate data meeting the specific absorption rate limiting requirement as the single-frequency power limiting value;
second, the maximum conduction power corresponding to the specific absorption rate data meeting the specific absorption rate limiting requirement is multiplied by a preset adjustment coefficient to obtain the single-frequency power limit value.
In the first mode, the maximum conduction power corresponding to the specific absorption rate data meeting the specific absorption rate limitation requirement is directly used as a single-frequency power limit value.
In the second mode, the maximum conduction power corresponding to the specific absorption rate data meeting the specific absorption rate limiting requirement is multiplied by a predetermined adjustment coefficient, the multiplication result is used as the obtained single-frequency power limit value, the predetermined adjustment coefficient can be corresponding to the terminal type, and the effect of setting the total power upper limit value can be further improved.
Further, in one embodiment, after determining the single frequency power limit according to the measured frequency channel and the measured antenna corresponding to the frequency band combination, the method further includes:
setting the single-frequency power limit value as the total power upper limit value of the terminal when working under the frequency band combination; and controlling the power of different frequency bands in the frequency band combination when the terminal works under the frequency band combination according to the total power upper limit value, wherein the sum of the powers of different frequency bands in the frequency band combination is smaller than or equal to the total power upper limit value.
The single-frequency power limit value is set as a total power upper limit value when the terminal works under the frequency band combination, and according to the total power upper limit value, the power of different frequency bands in the frequency band combination when the terminal works under the frequency band combination can be controlled, wherein the sum of the powers of different frequency bands in the specific control frequency band combination is smaller than or equal to the total power upper limit value.
For example, the total power upper limit value of the frequency band combination endcb5+n2 is limited to 20dBm, but the advantage is that the maximum power of the two frequency bands can be reached by both LTE B5 and NR N2, and the communication quality can be ensured even though the power of each frequency band is reduced less than the maximum power of the two frequency bands is limited by fixedly reducing the power of LTE B5 and NR N2. (for example, to achieve the same total power limit, the total power upper limit value of the frequency band combination ENDC B5+N2 of the previous method is 23dBm, however, the power of the LTE B5 and the NR N2 needs to be limited to be respectively not more than 17dBm, that is, the maximum power of each of the two frequency bands is not more than 17dBm. In the mode of the application, the total power upper limit value of the frequency band combination can be achieved by each of the LTE B5 and the NR N2, for example, one of the two frequency bands can reach the maximum 20dBm, and the power of the other frequency band is only low enough, for example, the power of-10 dBm).
