Abstract
The present invention provides a method and apparatus for performing device-to-device communication in a wireless communication system. The method includes generating identification information of a D2D user equipment that supports the D2D communication as identification information for D2D discovery using a hash function, the identification information for discovery includes information of a first length for indicating a division region of the beacon signals and information of a second length included in the beacon. The information of a first length and the information of a second length are smaller than identification information of the D2D user equipment. Accordingly, by performing discovery for the D2D user equipment through the identification information having shorter length than prior art, and performing discovery in a range where the discovery is available through the region in which the beacon signals are allocated, advantages of performing the D2D discovery effectively are provided.
