Claim Text:
1. A method for transmitting a relay node specific downlink physical control channel (R-PDCCH) and a downlink physical shared channel (PDSCH) to a relay node at a base station in a multiple antennae wireless communication system, the method comprising: transmitting the R-PDCCH and the PDSCH in two or more resource block (RB) pairs on a plurality of layers to the relay node, wherein, when a first slot of at least one RB pair among the two or more RB pairs on any layer of the plurality of layers is used for a transmission of the R-PDCCH, the PDSCH is mapped to resource element (RE) in the two or more RB pairs on the plurality of layers except for the first slot of the at least one RB pair on the plurality of layers, wherein the R-PDCCH includes a downlink assignment for the PDSCH, when the downlink assignment for the PDSCH indicates resource allocation which overlaps the at least one RB pair, the PDSCH is mapped to REs in a second slot of the at least one RB pair.
