Abstract  Abstract

In this application, a method is disclosed in which a first terminal within a base station coverage in a wireless communication system performs direct communication between a second terminal outside the coverage and the terminal. Specifically, the method comprises: dividing a specific time unit for direct communication between terminals into a plurality of candidate intervals; And generating a random number in one of the candidate intervals and transmitting a reference signal for synchronization acquisition to the second terminal if the random number is greater than or equal to a threshold value corresponding to the inside of the coverage, And the threshold value is smaller than the threshold value corresponding to the outside of the coverage.
