Abstract: The present invention relates to a method for receiving a downlink control signal in a wireless communication system including monitoring EPDCCH (enhanced physical downlink control channel) candidates to decode an EPDCCH in one or two EPDCCH sets on a first serving cell configured for the UE, and receiving a PDSCH (physical downlink shared channel) corresponding to the decoded EPDCCH. The EPDCCH candidates may include EPDCCH candidates for the first serving cell and EPDCCH candidates for a second serving cell scheduled by the first serving cell. Aggregation levels and the number of the EPDCCH candidates for the second serving cell at each of the aggregation levels are associated with bandwidth of the second serving cell.

Abstract: A method for resource allocation of a User Equipment (UE) configured to perform device-to-device (D2D) communication in a wireless communication system is discussed. The method includes receiving, from a serving base station, a message including information on a transmission resource region, where the information on the transmission resource region includes information on available resources to transmit D2D data for when the UE is in an out-sync condition, and transmitting, to another UE, the D2D data based on a part of the available resources included in the information on the transmission resource region when the UE is in the out-sync condition.
