Abstract

The embodiment of the invention provides a method and a terminal device for regulating antenna transmission power, which are applied to the technical field of communication, so as to solve the problemthat the terminal device mistakenly reduces the transmission power when transmitting radio frequency signals through the antenna. Specifically, the scheme is applied to a terminal device including anantenna.The method comprises the following steps of: acquiring a first image in the case of transmitting a radio frequency signal through an antenna, wherein the first image includes a biometric characteristic of a user; when the biometrics of the user matches the biometrics of the preset head, the transmitting power of the transmitted radio frequency signal is adjusted to be the target power, and the target power is the transmitting power corresponding to the preset head biometrics. The preset biometrics includes user's preset eyebrow feature, preset eye feature, preset nose feature, presetmouth feature and preset ear feature. The scheme is specifically applied to the scenario where the terminal equipment reduces the transmission power of the transmitted radio frequency signal.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for adjusting antenna transmission power and a terminal device. Background technique [0002] A terminal device will generate electromagnetic radiation during communication, so that users near the terminal device will also absorb a certain amount of electromagnetic radiation. Generally, a specific absorption ratio (Specific Absorption Ratio, SAR) of electromagnetic radiation can be used to measure the degree of influence of electromagnetic radiation generated by a terminal device on a human body. [0003] In the prior art, a terminal device may detect a distance between the terminal device and an object through a distance sensor in the terminal device. When the distance sensor detects that the distance value is less than or equal to a certain threshold, the terminal device may reduce the transmit power when the antenna transmits radio...
