Abstract:
1. A method of receiving data at a relay node in a wireless communication system supporting a Multi User-Multiple Input Multiple Output (Multi User-MIMO) antenna scheme, the method comprising: receiving, by the relay node, a relay physical downlink control channel (R-PDCCH) from a base station using a first antenna port information and a first scramble identity (SCID) via a resource block (RB) pair, wherein the R-PDCCH comprises information related to at least one of a second antenna port information and a second SCID; and receiving, by the relay node, a downlink data channel from the base station using the R-PDCCH, wherein the downlink data is received using the first antenna port and the first SCID if a region in which the downlink data is received is assigned to a part of a RB bundle applied a precoding identical to a precoding applied to the RB pair via which the R-PDCCH is received, and wherein the downlink data is received using the second antenna port and the second SCID indicated by the R-PDCCH if the region is assigned to a part of a RB bundle applied a precoding different from the precoding applied to the RB pair via which the R-PDCCH is received.
