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.
