Abstract: A method of receiving control information for a device-to-device (D2D) communication by a user equipment (UE) in a wireless communication system. The method includes receiving a configuration for radio resources for the D2D communication; and receiving a downlink control information (DCI) on a specific radio resource among the radio resources, according to the configuration. If the DCI configured with a DCI format 0 is scrambled with a semi-persistent scheduling (SPS)—radio network temporary identifier (RNTI) for the UE specific, the DCI is considered as a valid semi-persistent activation or release.
