Abstract  Abstract

In this application, a method of performing direct communication between terminals of terminals outside the base station coverage in a wireless communication system is disclosed. Specifically, the method comprises: dividing a specific time unit for direct communication between terminals into a plurality of candidate intervals; Detecting a reference signal transmitted from a second one of the terminals in one interval excluding the last one of the candidate intervals; Obtaining synchronization for direct communication with the second terminal based on the reference signal; And transmitting the predefined acknowledgment signal in the last section of the candidate sections or the next time unit of the specific time unit.
