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.

Abstract: Disclosed are a method for controlling power and an apparatus therefor in a wireless communication system supporting device-to-device (D2D) communication. Specifically, a method for a terminal for controlling the transmission power of a physical sidelink discovery channel (PSDCH) in a wireless communication system supporting D2D communication comprises the steps of: calculating the sum of reception strengths of the total number of PSDCHs received from a set PSDCH reception period; and transmitting the PSDCH, wherein if the sum of reception strengths of the total number of PSDCHs is greater than a previously set threshold value, then the PSDCH to be transmitted is transmitted under the transmission power controlled by the terminal, and if the sum of reception strengths of the total number of PSDCHs is less than a previously set threshold value, then the PSDCH to be transmitted can be transmitted under the maximum transmission power.
