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

摘要

The present invention provides a method and an apparatus for performing a device-to-device (D2D) communication service in a wireless communication system. More particularly, D2D terminals supporting D2D communication are identified, discovery groups are formed for the D2D terminals using the same application, and a discovery timing is established depending on the discovery group, wherein the D2D terminals belonging to the same discovery group are shifted to an active state during the discovery timing so as to transreceive signals by using time and frequency resources designated for D2D discovery, wherein the discovery timing is set so as to have a variable value depending on the discovery group.
