Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method of obtaining synchronization for device-to-device direct communication for user equipment units located outside a coverage of a base station in a wireless communication system.

SOLUTION: A method of transmitting a synchronization signal for a device-to-device (D2D) link in user equipment (UE) located outside a coverage of a base station comprises: receiving from first UE located inside the coverage of the base station a first synchronization signal for the D2D link; and transmitting a second synchronization signal for the D2D link. The first synchronization signal and the second synchronization signal are generated based on at least one identical parameter.
