    Abstract: 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.

    Abstract: According to one embodiment, a method of allocating a radio resource for a relay station includes: transmitting configuration information through a higher layer signal, the configuration information including information regarding an OFDM symbol at which a relay zone begins; allocating the relay zone to the relay station in a subframe based on the configuration information; and transmitting a relay control channel to the relay station in the relay zone. The subframe includes OFDM symbols in a time domain and subcarriers in a frequency domain. The relay zone includes a subset of the OFDM symbols in the time domain and a portion of the subcarriers in the frequency domain. The configuration information indicates an OFDM symbol from among a second OFDM symbol, a third OFDM symbol and a fourth OFDM symbol. The relay control channel is transmitted from the fourth OFDM symbol of the subframe.

    Abstract: The present invention relates to a relay node device for receiving control information from a base station and a method therefor. The relay node device according to the present invention comprises: a receiver, which receives information about an area where a relay-physical downlink control channel (R-PDCCH), the channel for transmitting control information for the relay node from a base station, is allocated; a processor, which searches for at least one R-PDCCH for the relay node based on the R-PDCCH allocation information received; and an R-PDCCH receiver, which receives the at least one R-PDCCH from the fourth symbol of the first slot in a downlink backhaul subframe of the area where the at least one R-PDCCH searched for by the processor has been allocated.
