A method and an apparatus of mapping a resource unit is provided. Physical resource units (PRUs) are divided into a plurality of PRU sets. The PRUs are mapped to a subband PRU or a miniband PRU in a granularity of the PRU set. The mapping is based on the greatest common divisor of the maximum number of PRU sets. The resource unit can be effectively mapped while maximizing a frequency diversity gain of a subband PRU and a miniband PRU.

A method for retransmitting data in wireless communication system is disclosed. MS can receive a NACK (Not-Acknowledge) signal from a base station (BS) through a specific downlink subframe of a specific frame in a first superframe, and the MS can retransmits the data using a second uplink subframe in a first frame in a second superframe subsequent to a first superframe. In this case, a index of the second uplink subframe may be 1. The wireless communication system can support the Half-Frequency Division Duplex (H-FDD) scheme. A first uplink subframe in the first frame of the second superframe can be punctured.

A method and apparatus for transmitting a signal in a wireless communication system are disclosed. The signal transmission method includes generating encoded packet data for transmission on an uplink, setting distributed resources in a plurality of contiguous subframes, and transmitting at least part of the encoded packet data through the distributed resources to a base station. The distributed resources are interleaved on a subframe basis according to a permutation pattern and the permutation pattern is different for each subframe.

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.

A method of allocating a paging carrier in a multi-carrier environment is disclosed. The method of allocating the paging carrier includes receiving a first message including first allocation information of the paging carrier, transmitting a second message for requesting entry into an idle mode to a base station; and receiving a third message including second allocation information of a changed paging carrier from the base station. At this time, the paging carrier includes a paging channel out of multiple carriers including one or more carriers.
