Abstract
A method and a terminal for controlling transmission power are disclosed. The method includes: after determining that a human body is close to the terminal, measuring a distance between the human body and the terminal by using a radio frequency fingerprint identification circuit; and controlling transmission power of an antenna in a radio frequency antenna unit based on the distance. In this way, no separate SAR reduction sensor module circuit needs to be added to measure a parasitic capacitance generated when the human body is close to the intelligent terminal, greatly reducing complexity of a hardware design of a radio frequency module. In this embodiment of the present disclosure, the transmission power is controlled based on the distance between the human body and the terminal, thereby enabling the control of the transmission power to have relatively high precision and accuracy.
