    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 wireless communication system, and more particularly, to a method and an apparatus for transmitting reference signals in uplink MIMO transmission. According to one embodiment of the present invention, the method for transmitting uplink signals through a terminal in the wireless communication system comprises the steps of: receiving control information including the information on a cyclic shift and/or an orthogonal cover code; allocating the multiplexed reference signals onto an uplink subframe; and transmitting the subframe through a multi-antenna. When the uplink MIMO transmission is multiuser MIMO transmission, the reference signals of the terminal and the reference signals of other terminals can be multiplexed by using the orthogonal cover code.

    摘要: Provided are a method and apparatus for transmitting a reference signal in a multi-antenna system. A terminal generates a plurality of reference signal sequences in which cyclic shift values different from each other are allocated to the respective plurality of layers, and generates a single carrier-frequency division multiple access (SC-FDMA) symbol to which the plurality of reference signal sequences are mapped. The SC-FDMA symbol is transmitted to a base station via a plurality of antennas. The cyclic shift values allocated to the respective layers are determined on the basis of a first cyclic shift value, which is a cyclic shift value allocated to a first layer from among the plurality of layers, and cyclic shift offsets which are allocated to the respective layers and which are different from each other.
