A method is presented for configuring a device-to-device (D2D) mode by an eNodeB (eNB) in a wireless communication system. The eNB configures the D2D mode indicating which D2D mode a user equipment (UE) operates in for a D2D communication. The eNB transmits an information on the configured D2D mode to the UE. The D2D mode is one of an evolved-universal mobile telecommunications system (UMTS) terrestrial radio access network (E-UTRAN) planned mode or a UE autonomous mode. The E-UTRAN planned mode is a D2D mode in which the eNB controls radio resources for the D2D communication, and the UE autonomous mode is a D2D mode in which the UE controls radio resources for the D2D communication.
