Abstract: A power control method includes: obtaining, by a first terminal, power control information, where the power control information is information used to control a transmit power used by the first terminal when the first terminal communicates with a second terminal; determining a target transmit power based on the power control information; and sending first data to the second terminal based on the target transmit power. A first communication link is established between the first terminal and the second terminal. In the present disclosure, the following prior-art problem is resolved: In a relay or D2D communication scenario, a base station does not configure, for a specific terminal, a transmit power used by the terminal during D2D communication. Therefore, transmit powers used by different terminals during D2D communication are indicated to the different terminals, and a power control effect is improved.
