Abstract: The present disclosure relates to a method for allocating resource performed by a base station in a wireless communication system that supports a direct communication between user equipments (UEs) includes acquiring position information and transmission power of a first UE and a second UE; and allocating the resource to the first UE and the second UE based on the acquired position information and transmission power of the first UE and the second UE, wherein allocating the resource preferentially allocates the resource to the first UE.

Abstract: Disclosed are a terminal discovery method in a wireless communication system supporting device-to-device (D2D) communication, and a device therefor. The method for discovering a terminal in a wireless communication system supporting device-to-device (D2D) communication, includes transmitting, by a terminal, a discovery signal, and receiving, by the terminal, a response signal as a response with respect to the discovery signal from a different terminal, wherein the response signal is transmitted by the different terminal when a response delay time determined on the basis of a reception signal-to-interference noise ratio (SINR) terminates.
