    摘要: A method for receiving data by a relay station (RS) in a wireless communication system includes: receiving radio resource allocation information via an R-PDCCH (R-Physical Downlink Control Channel); and receiving data from a base station (BS) via an R-PDSCH (R-Physical Downlink Shared Channel) indicated by the radio resource allocation information, wherein the radio resource allocation information includes information regarding an allocation of resource blocks in a frequency domain and information regarding an allocation of OFDM symbols in a time domain. Since the radio resource allocation information providing information regarding a time relationship between a control channel transmitted by the BS to a UE and a control channel transmitted by the RS to a UE connected to the RS is provided, the RS can reliably receive a signal transmitted from the BS in a backhaul link between the BS and the RS in a wireless communication system including the RS.

    摘要: A repeater apparatus for detecting a downlink HARQ ACK/NACK feedback signal from a base station is provided. An RF (Radio Frequency) unit receives specific channel configuration information which includes offset information indicating the starting point of a specific channel to which said HARQ ACK/NACK feedback signal is transmitted from the base station and the position of the specific channel allocated for an exclusive use of the repeater apparatus within the specific channel from said start point, and receives the HARQ ACK/NACK feedback signal from the base station for an uplink transmission of the repeater. The processor detects the specific channel allocated for exclusive use of the repeater apparatus based on the received specific channel configuration information thereby decoding the received HARQ ACK/NACK feedback signal.
