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.

A method for demodulating, by a relay node (RN), a relay physical downlink control channel (R-PDCCH) in a wireless communication system, the method comprising:
- 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,
- wherein 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.
A relay node (RN) in a wireless communication system, the RN comprising:
- a memory;
- a radio frequency (RF) unit;
- and
- a processor, coupled to the memory and the RF unit, and that demodulates a relay physical downlink control channel (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,
- wherein 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.
