METHOD FOR DETERMINING TRANSMIT POWER FOR DIRECT DEVICE TO DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

Disclosed is a method for performing, by a device, power reporting to a base station for a direct device to device communication in a wireless communication system. Specifically, the method comprises the steps of: receiving a transmit power control (TPC) command for a direct device to device communication from the base station; sending a direct device to device communication signal by determining the transmit power of a direct device to device communication according to the TPC command; and reporting the difference between the determined transmit power and a certain power to the base station.
