Abstract

A power control method for P2P communication to be executed by a UE is provided, comprising the steps of: (a) receiving P2P signals transmitted via P2P direct link from another UE and control signals transmitted via control downlink from a network system; (b) determining the UE's transmission power according to the TPC command included in the P2P signals and the TPC command included in the control signals.
