Problems solved by technology

The current SAR adjustment method is to adjust the SAR by limiting the antenna power near the part of the human body. However, since the 5G terminal is very sensitive to the reduction of the antenna transmission power, the power limitation caused by many false touches will greatly affect the communication capability of the 5G terminal. degraded user experience
Therefore, when the existing SAR adjustment method is applied to 5G terminals, there is still the problem of low reliability of communication capabilities of 5G terminals due to unnecessary power limitations

Embodiment approach 1

[0036] Embodiment 1: The distance between the human body and each antenna is determined according to the capacitance value of each antenna; the user's holding state of the mobile terminal is determined based on the distance corresponding to each antenna.

[0037] The induction of the above sensor mainly produces capacitance changes through the change of the contact area between the human body and the pole plate formed by the antenna. Therefore, the distance between the human body and the antenna formed by the pole plate is different, and the resulting capacitance value is different. Therefore, according to each antenna The capacitance value can determine the distance between the human body and each antenna. Since when determining the user's holding state of the mobile terminal, the positions of each antenna of the mobile terminal must be determined, see for example figure 2 The schematic diagram of the antenna distribution of the mobile terminal is shown. The bottom of the mo...

Embodiment approach 2

[0040] Embodiment 2: In this embodiment, the user's holding state of the mobile terminal is determined according to the capacitance value of each antenna, see for example image 3 The flow chart of the method for determining the user's holding state of the mobile terminal shown in the figure can be specifically executed with reference to the following steps S302 to S304:

[0041] Step S302: Determine the contact level between the human body and the antenna according to the capacitance value of each antenna; the higher the contact level, the closer the human body is to the antenna.

[0042] Determine the distance between the human body and the antenna according to the capacitance value of each antenna; when the distance between the human body and the antenna is between the first preset distance and the second preset distance, determine that the contact level of the antenna is the first trigger level; When the distance of the antenna is less than or equal to the second preset di...

Embodiment approach 3

[0045] Embodiment 3: In this embodiment, the user's holding state of the mobile terminal is determined according to the capacitance value of each antenna. Specifically, it can be executed with reference to the following steps a to c:

[0046] Step a: Establish a capacitance array according to the capacitance value of each antenna; wherein, the capacitance value of each antenna is sequentially recorded in the capacitance array.

[0047] The above capacitance array may also be a capacitance vector established by the capacitance values ​​of each antenna. For example, when the mobile terminal is provided with six antennas a1-a6, respectively obtain the capacitance values ​​C1-C6 of the antennas a1-a6, then the capacitance array can be [C1, C2, C3, C4, C5, C6], the above-mentioned capacitance vector Can be (C1,C2,C3,C4,C5,C6).

[0048] Step b: Compare the capacitor array with the preset capacitor array to obtain the comparison result; the preset capacitor array includes the capaci...

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for adjusting transmission power of a mobile terminal and a mobile terminal. Background technique [0002] With the continuous development of science and technology, the application of mobile terminals is becoming more and more extensive, but the radiation generated by mobile terminals itself will affect the human body, and the degree of influence can be expressed by Specific Absorption Rate (SAR). Different regions The respective communication frequency bands have different certification standards for the SAR value of the mobile terminal, and the mobile terminal can enter the area for normal use only after adjusting its own radiation to the SAR certification standard adapted to the corresponding area. The current SAR adjustment method is to adjust the SAR by limiting the antenna power near the part of the human body. However, since the 5G ter...
