US 10,455,513 B2 · Power control method and apparatus in V2X communication

Abstract

The present application provides a power control method in a V2X communication, comprising the following steps of: acquiring, by a UE, power control parameters of a Physical V2X Shared Channel (PVSCH) or a Physical V2X Control Channel (PVCCH) in a V2X communication, the power control parameters comprising a second basic open-loop power, the second basic open-loop power reflecting an interrelationship between different V2X UEs; and, determining, by the UE, a transmission power of the PVSCH or the PVCCH according to the acquired power control parameters. With the present application, the performance of the V2X communication can be improved, and the power consumption of a V2X terminal can be reduced.
