Power control parameter configuration by base station
First Claim
1. A power control method, comprising:
- receiving, by a user equipment (UE), a power control parameter set configured by a base station and sent by the base station, wherein the power control parameter set comprises at least one power control parameter group comprising power control parameters PO, α
, and Δ
, PO is a target power for receiving a signal by the base station, α
is a path loss compensation coefficient, and Δ
is an offset parametric value for power control;
determining, by the UE, a first power control parameter group according to the power control parameter set; and
determining, by the UE, a device-to-device transmit power PD2D of the UE according to PD2D=PO+α
·
PL+Δ
, where PL is a path loss from the base station to the UE.

Abstract
A method includes: receiving, by a UE, a power control parameter set sent by a base station, where the power control parameter set includes at least one power control parameter group, where the power control parameter group includes at least one power control parameter; determining, by the UE, a first power control parameter group according to the power control parameter set; and determining, by the UE, a transmit power of the UE according to a power control parameter in the first power control parameter group. so that the UE obtains through calculation, according to the power control parameter in the first power control parameter group, the transmit power that satisfies a service currently initiated by the UE, and a communication range of the UE is ensured.
