Abstract:
A method and a relay node (RN) for demodulating a relay physical downlink control channel (R-PDCCH) in a wireless communication system are discussed. The method according to an embodiment includes demodulating the R-PDCCH based on cell-specific reference signals transmitted on at least one first antenna port or based on user equipment (UE)-specific reference signals transmitted on a second antenna port. A type of reference signals among the cell-specific reference signals or the UE-specific reference signals, which is being used to demodulate the R-PDCCH, is configured by a higher layer.
