Abstract: The present specification relates to a method in which a base station efficiently notifies a transmitting terminal of a resource domain for transmitting control information and data in a wireless communication system supporting device-to-device (D2D) communication. To this end, the transmitting terminal receives resource allocation information associated with D2D communication from the base station, and transmits, to a receiving terminal, control information (SA) for D2D communication and data corresponding to the SA on the basis of the resource allocation information received from the base station, wherein a time domain location for transmitting the SA has a predetermined time domain pattern on the basis of the resource allocation information received from the base station, and a frequency domain location for transmitting the SA can be determined in advance by one of two specific hopping patterns.

Abstract: A method for receiving an Enhanced Physical Downlink Control Channel (EPDCCH) from a base station by a user equipment (UE) in a wireless communication system. The UE receives a first EPDCCH for a first carrier by monitoring first EPDCCH candidates for the first carrier in a specific physical resource block (PRB) pair set. The UE receives a second EPDCCH for a second carrier by monitoring second EPDCCH candidates for the second carrier in the specific PRB pair set. A position of the second EPDCCH candidates is determined by applying an offset value for the second EPDCCH candidates into a position of the first EPDCCH candidate. The offset value for the second EPDCCH candidates is determined based on a carrier indicator field of the second carrier.
