    摘要: 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.

    摘要: Disclosed is a method for transmitting a sounding reference signal from a terminal to a base station in a radio communication system. More specifically, the method comprises the steps of: receiving downlink control information from a base station; checking a flag bit included in said downlink control information; checking an interpretation bit is included in said downlink control information, when said flag bit indicates an uplink; and transmitting an additional sounding reference signal and/or an uplink common channel based on said interpretation bit.
