A METHOD OF TRANSMITTING A SYNCHRONIZATION SIGNAL FOR A DEVICE-TO-DEVICE OPERATION PERFORMED BY A USER EQUIPMENT IN A WIRELESS COMMUNICATION SYSTEM AND THE USER QUIPMENT USING THE SAME

摘要

The present invention provides a method of transmitting a synchronization signal for a device-to-device (D2D) operation by a terminal in a wireless communication system and a terminal using the same. The method of transmitting a synchronization signal for a D2D operation by a terminal in a wireless communication system establishes a radio resource control (RRC) connection to a first cell of a first frequency, transmits a D2D synchronization signal (D2DSS) by a second cell of a second frequency, and determines whether to transmit the D2DSS based on reference signal-received power (RSRP) received from the second cell if the second frequency is different from the first frequency.
