    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: The present invention relates to a method in which user equipment transmits a non-periodic sounding reference signal in a wireless communication system. In detail, the method comprises: a step of receiving a downlink control channel from a base station; a step of decoding a downlink control information (DCI) format contained in the downlink control channel; a step of checking a non-periodic sounding reference signal transmission instruction in the DCI format; and a step of transmitting a non-periodic sounding reference signal to the base station in accordance with the transmission instruction. Preferably, if the downlink control channel is received via an nth subframe, the non-periodic sounding reference signal is transmitted via an (n+k)th subframe (where k≦4).
