Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method by which a first terminal inside a coverage of a base station performs inter-terminal direct communication with a second terminal outside the coverage in a wireless communication system.

SOLUTION: The method comprises the steps of: dividing into a plurality of candidate sections a specific time unit for the inter-terminal direct communication; and transmitting a reference signal for obtaining synchronization to the second terminal from one section among the candidate sections when a random number that is generated is greater than or equal to a critical value corresponding to the inside of the coverage where the critical value corresponding to the inside of the coverage is smaller than a critical value corresponding to the outside of the coverage.
