Abstract: A method and apparatus for using resources for a device-to-device (D2D) operation in a wireless communication system is provided. A user equipment (UE) receives D2D resources used for transmission of D2D signals in radio resource control (RRC) idle mode, and transmits the D2D signals by using the D2D resources in the RRC idle mode. The D2D resources may be used in the RRC idle mode only, or may be used after entering the RRC connected mode. Alternatively, the UE receives D2D resources used for transmission of D2D signals in RRC connected mode, and transmits the D2D signals by using the D2D resources in the RRC idle mode.

Abstract: PDCCH (Physical Downlink Control Channel) monitoring operation regardless of the DRX configuration is disclosed. The UE operating in a wireless communication system receives DRX (Discontinuous Reception) configuration information from a network. When the UE transmits a specific indication, the UE ignores the DRX configuration information and monitor a PD-CCCH after transmitting the specific indication.

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.
