METHOD AND APPARATUS FOR PERFORMING DEVICE TO DEVICE SERVICE IN WIRELESS COMMUNICATION SYSTEM

摘要

One embodiment of the present invention provides a method and an apparatus for performing device to device (D2D) service in a wireless communication system, and specifically, provides a method for using a discovery signal including an identifier which can be identified in a physical layer and the like when a terminal supporting a D2D service receives a signal related to an advertisement. The invention determines whether to receive an additional advertisement signal on the basis of the identifier. The discovery signal is preferably transmitted in a radio resource control (RRC) idle mode. The D2D terminal that receives the discovery signal communicates with a base station by an improved method having an improved effect with respect to power.
