POWER CONTROL METHOD FOR DEVICE-TO-DEVICE (D2D) COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

The present invention relates to a method for power control by a first terminal that performs device-to-device (D2D) communication in a wireless communication system. More specifically, the method comprises the steps of: receiving, from a base station, a first signal including power control information defined for D2D communication; and transmitting a second signal according to transmission power determined on the basis of the received first signal, wherein the power control information indicates one of broadcast and groupcast, and the second signal is differently masked and transmitted according to a transmission method of the second signal.

主权项

1. A method of controlling transmit power by a first user equipment performing D2D (device-to-device) communication in a wireless communication system, comprising the steps of:
receiving a first signal containing power control information defined for the D2D communication from a base station; and transmitting a second signal according to transmit power determined based on the received first signal, wherein the power control information indicates one of broadcast and groupcast and wherein the second signal is transmitted in a manner of being differently masked according to a transmission scheme of the second signal.
