Claim Text:
1. A method of performing, by a terminal, a hybrid automatic repeat request (HARQ) in a wireless access system supporting peer-to-peer (P2P) communication between terminals, the method comprising: receiving control information for P2P communication from a base station; transmitting data to an other terminal in a downlink subframe or uplink subframe defined as a transmission zone for transmission to the other terminal based on the received control information; and receiving an acknowledgement (ACK) or a not-acknowledgement (NACK) for the transmitted data in an uplink subframe, associated with the downlink or the uplink subframe, among subframes defined as a reception zone for reception from the other terminal, wherein the control information includes frame structure information used for the P2P communication, wherein the frame structure information includes information related to an arrangement of the transmission zone and the reception zone in a frame and information related to an HARQ linkage between subframes, wherein the HARQ linkage between the subframes is configured so that a subframe associated for an HARQ does not overlap a subframe allocated for receiving a signal from the base station, wherein the information related to the HARQ linkage between the subframes includes information related to a processing delay time for a downlink (DL) HARQ procedure and a processing delay time for an uplink (UL) HARQ procedure, and wherein the processing delay time for the DL HARQ procedure and the processing delay time for the UL HARQ procedure are set to be the same or are set to be different.
