| 发明名称 | Method of receiving data from base station at relay node in wireless communication system and apparatus thereof | ||
| 摘要 | A method is described for transmitting a physical downlink shared channel (PDSCH) to a relay node at a base station in a multiple antenna wireless communication system. The method includes modulating a relay-node-specific physical downlink control channel (R-PDCCH) based on a relay-node-specific reference signal, and transmitting the R-PDCCH and the PDSCH to the relay node. If the R-PDCCH is modulated based on the relay-node-specific reference signal and carries a specific downlink control information, the PDSCH is encoded based on a predetermined antenna port and a predetermined scrambling identifier (SCID). | ||
