摘要
The present invention relates to a method in which a base station transmits signals to a relay node in a multiuser multi-antenna (MIMO) wireless communication system. More particularly, the method comprises the following steps: allocating one or more antenna ports to one or more relay nodes, respectively; mapping each of a plurality of downlink grant signals for said one or more relay nodes to a preset resource domain from among resource domains corresponding to one of the allocated antenna ports; mapping uplink grant signals or data signals for said one or more relay nodes to the resource domains corresponding to the allocated antenna ports; and transmitting the mapped signals to said one or more relay nodes.
