Abstract:
Provided are a method by which a terminal transmits a synchronization signal for a device-to-device (D2D) operation in a wireless communication system, and the terminal using the method. The method comprises: forming a radio resource control (RRC) connection with a first cell of a first frequency; and transmitting a D2D synchronization signal (D2DSS) in a second cell of a second frequency, wherein when the second frequency is different from the first frequency, whether to transmit the D2DSS is determined on the basis of reference signal received power (RSRP) received from the second cell.
