METHOD FOR TRANSCEIVING SIGNALS BETWEEN A BASE STATION AND A RELAY NODE IN A MULTIUSER MULTI-ANTENNA WIRELESS COMMUNICATION SYSTEM, AND APPARATUS FOR SAME

摘要

The present invention relates to a method in which a base station transmits a relay node specific downlink physical control channel (R-PDCCH) and a downlink physical shared channel (PDSCH) to a relay node in a multi-antenna wireless communication system. More particularly, the method comprises mapping the R-PDCCH to resource elements (REs) in a first slot of at least one resource block (RB) pair of one or more RB pairs on a specific antenna port among a plurality of antenna ports; mapping the PDSCH to REs in the one or more RB pairs on the plurality of antenna ports; and transmitting the mapped R-PDCCH and the mapped PDSCH to the relay node. In this case, the PDSCH is not mapped to any RE in the first slot of the at least one RB pair on the plurality of antenna ports.
