A method of allocating a radio resource for a relay station in a wireless communication system is disclosed. The method comprise allocating a relay zone to the relay station in a subframe and transmitting a relay control channel to the relay station by using the relay zone, wherein the subframe comprises a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a time domain and a plurality of subcarriers in a frequency domain, wherein the subframe is divided into a user zone used by a user equipment in a cell and the relay zone used by the relay station, and wherein the relay zone comprises some of the plurality of subcarriers. According to the present invention, a subframe structure provides backward compatibility with a legacy wireless communication system. A relay station can effectively find a radio resource allocated to the relay station, thereby decreasing a decoding time.

The present invention relates to a method for transmitting an uplink or downlink grant in a wireless communication system that supports uplink and downlink multiple input multiple output (MIMO) schemes. The method comprises: determining a downlink control information (DCI) format for an uplink or downlink grant to generate control information: attaching a cyclic redundancy check (CRC) for detecting an error in the created control information; and channel-coding the CRC-attached control information, wherein the control information comprises a bit flag for distinguishing whether the grant is an uplink grant or a downlink grant.

A method and an apparatus of transmitting a control signal in a wireless communication system is provided. They generate a first-spread sequence by spreading a modulated sequence in the first slot by using a first orthogonal sequence, generate a second-spread sequence by spreading a modulated sequence in the second slot by using a second orthogonal sequence. The first spread sequence and the second spread sequence are transmitted in a subframe. A length of the first orthogonal sequence is shorter than a length of the second orthogonal sequence, the second orthogonal sequence is generated by removing at least one element included in the first orthogonal sequence, and the at least one element to be removed is identical in every index of the first orthogonal sequence.
