Patent ID: 8547896

Claim:
A method of transceiving signals at a relay node (RN) via a specific downlink subframe in a wireless communication system, the method comprising: selectively transmitting a physical downlink control channel (PDCCH) to at least one user equipment (UE) in a relay cell at a first timing point after a time corresponding to a propagation delay in accordance with a distance between a base station (BS) and the RN from a specific downlink subframe start timing point of the BS or at a second timing point after an elapse of a time corresponding to a prescribed delayed symbol from the first timing point; and receiving a relay-PDCCH (R-PDCCH) or a physical downlink shared channel (PDSCH) from the BS after elapse of a first guard time subsequent to an interval of the PDCCH, wherein a prescribed number of symbols are allocated to the PDCCH, and wherein a second guard time is allocated in continuation with the received R-PDCCH or the received PDSCH, wherein the first guard time corresponds to one of a 0.5 symbol duration, a 1 symbol duration, a 1.5 symbol duration, 2 symbol durations, 2.5 symbol durations and 3 symbol durations, and wherein the second guard time corresponds to a 0.5 symbol duration or a 1 symbol duration.
