US 2019/0174429 A1 · POWER CONTROL METHOD AND APPARATUS, TERMINAL, AND NETWORK DEVICE

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.

Dependent claims

A device, comprising:

a processor;
and
a non-transitory memory, wherein the memory stores execution instructions which, when executed by the processor, enable the device to:
obtain power control information for controlling a transmit power to be used by the device when the device communicates with a second terminal and a first communication link is established between the device and the second terminal,
determine a target transmit power based on the power control information, and
send first data to the second terminal based on the target transmit power.
