摘要:
Provided are a method for receiving information on a relay node zone and reference signals for a relay node from a base station, and a relay node device using same. The relay node can receive information on at least one start point from the start points of a Relay-Physical Downlink Control Channel (R-PDCCH) and a Relay-Physical Downlink Shared Channel (R-PDSCH) for transmitting a signal from a base station to a relay node in a specific downlink subframe. Alternatively, the relay node can implicitly recognize the start points of the R-PDCCH and R-PDSCH set in advance. The relay node can recognize a signal from the base station in the specific downlink subframe based on the start point information after the time corresponding to at least one of the start points of the R-PDCCH and R-PDSCH. Also, the relay node can decode signals transmitted from a base station after the corresponding timing.
