METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM INCLUDING RELAY STATION |
| 摘要 |
A method and an apparatus for demodulating a downlink control channel by a relay node (RN) in a wireless communication system. The method includes receiving cell-specific reference signals on at least one antenna port from a base station (BS); receiving user equipment (UE)-specific reference signals on at least one antenna port from the BS; and demodulating a relay physical downlink control channel (R-PDCCH) based on either the cell-specific reference signals or the UE-specific reference signals. A type of reference signals used to demodulate the R-PDCCH is configured by higher layers. |

1. A method of demodulating a downlink control channel by a relay node (RN) in a wireless communication system, the method comprising:
receiving cell-specific reference signals on at least one antenna port from a base station (BS); receiving user equipment (UE)-specific reference signals on at least one antenna port from the BS; and demodulating a relay physical downlink control channel (R-PDCCH) based on either the cell-specific reference signals or the UE-specific reference signals, wherein a type of reference signals used to demodulate the R-PDCCH is configured by higher layers. |
