    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: A method for communicating with a relay station is disclosed. The method for communicating with a relay station comprises transmitting resource allocation information of downlink traffic and uplink traffic from a base station to the relay; and transmitting the downlink traffic to the relay by encapsulating the downlink traffic in accordance with the resource allocation information and receiving encapsulated uplink traffic from the relay in accordance with the resource allocation information. It is possible to enable efficient communication through a relay using a minimum interface without deterioration of throughput even in the case that a base station does not know detailed attributes of a relay existing in a system. Also, it is possible to coordinate collision through a master relay in case of a system supporting multi-hop relays.
