[0023] like figure 1 As shown, the embodiment of the present invention provides a method for setting the transmit power of the terminal antenna, including:

[0024] Step 101: When the terminal is in a talking state and the distance between the user and the terminal is less than a preset distance, determine whether the specific absorption rate SAR of the terminal antenna is greater than a preset SAR value.

[0025] When the terminal is in the talking state, the proximity sensor can be used to detect whether the distance between the user's face and the terminal is less than the preset distance, and the proximity sensor detects that the distance between the user's head and the terminal is less than the preset distance, that is When the user's head is close to the terminal, it is judged whether the SAR of the terminal antenna is greater than the preset SAR value.

[0026] Specifically, when judging whether the SAR of the terminal antenna is greater than the preset SAR value, it c...

Abstract

The invention provides a terminal antenna transmitting power setting method and a terminal. The problem that the SAR and conversation performance are difficult to meet simultaneously by terminal antenna transmitting power is solved. The terminal antenna transmitting power setting method comprises the steps that when the terminal is in a conversation state and the distance between a user and the terminal is smaller than a preset distance, whether the absorptivity SAR of a terminal antenna is greater than a preset SAR value or not is judged; if the absorptivity SAR is greater than the preset SAR value, the preset transmitting power is reduced according to the relation between a volume value of microphone input voice and a preset volume threshold value in real time, and the transmitting power obtained after reduction processing is set as the transmitting power of a terminal antenna. When the volume value of the microphone input voice is greater, the pre-configured transmitting power is reduced somewhat; when the volume value of current microphone input voice of the terminal is smaller or even is zero, the pre-configured transmitting power is reduced much, and the conversation performance of the terminal is ensured on the premise that the SAR of the terminal antenna does not exceed the standard.

Description

technical field [0001] The present invention relates to the technical field of terminal antennas, in particular to a method for setting transmit power of a terminal antenna and a terminal. Background technique [0002] At present, with the development of science and technology, mobile phones tend to be ultra-thin, miniaturized, metallized, and broadband multi-frequency development, and people have higher and higher requirements for the performance of mobile phone antennas. Radiation is also bound to increase, so that the contradiction between antenna performance and Specific Absorption Ratio (SAR) always exists. When setting the transmission power of the antenna, it is difficult to meet the SAR value of the antenna and ensure the good performance of the mobile phone antenna. performance. For example, the total radiated power (Total Radiated Power, TRP) of the antenna on the mobile phone is 5dB different from the SAR of the human head. In order to meet the requirements of th...
