| 摘要 |
The present invention discloses a method and apparatus for relay station downlink cooperative retransmission, wherein said method comprises: a relay station carrying out physical layer processing in advance on data which requires retransmitting according to a case that available wireless resources number for retransmitting data in a retransmission subframe is to be determined, generating corresponding Orthogonal Frequency Division Multiplexing (OFDM) signals, and monitoring a Physical Control Format Indicator Channel (PCFICH) of the retransmission subframe, and according to a monitoring result, selecting an OFDM signal which matches with the determined available wireless resources number from said OFDM signals to carry out retransmission transmitting. |
