    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: A device and method for permuting subcarriers in a subframe which is divided into a plurality of frequency partitions in a wireless mobile communication system is disclosed. The method includes mapping, at a mobile station, physical resource units for localized resource allocation to a frequency partition of the plurality of frequency partitions in units of N_1 number of resource units, and physical resource units for distributed resource allocation to the frequency partition in units of N_d number of resource units, N_1 being different from N_d; and spreading, at the mobile station, subcarriers of the physical resource units for distributed resource allocation across the whole distributed resource allocations.
