    • The 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 different scenarios associated with different possible number of available wireless resources for retransmitting data in a retransmission subframe, generating corresponding OFDM signals, and monitoring the PCFICH of the retransmission subframe, and according to the monitoring result, selecting an OFDM signal which is corresponding to the determined number of available wireless resources from said OFDM signals to carry out retransmission transmitting. The present invention can efficiently solve the problem that the number of wireless resources varies during downlink retransmitting data and the relay station cooperative communication is unable to be carried out normally, without introducing any extra overhead and time delay, and without the control signaling, thus reducing the system complexity.
    • 本发明公开了一种用于中继站下行协同重传的方法和装置,其中所述方法包括:中继站预先对需要根据不同可能数量的可用无线资源的不同情况进行重传的数据进行物理层处理,以重传数据 在发送子帧中生成对应的OFDM信号,监视重发子帧的PCFICH,根据该监视结果,从所述OFDM信号中选择与确定的可用无线资源数相对应的OFDM信号,进行重传发送 。 本发明可以有效地解决下行重传数据期间无线资源数量变化,中继站协作通信不能正常执行的问题,而不引入任何额外的开销和时间延迟,并且没有控制信令,从而减少 系统复杂性。

    • The present disclosure provides a mapping and resource allocation method for R-PDSCH, including: when resources allocated for an R-PDCCH overlap with resources allocated for the R-PDSCH, data of the R-PDSCH is not mapped or sent on over-lapped resources, or the data of the R-PDSCH to be sent on the over-lapped resources is punctured; the data of the R-PDSCH is mapped and sent on all or partial resources which are not occupied by the R-PDCCH; a receiving end receives data according to the mapping method for the R-PDSCH; wherein a resource allocation mode corresponding to a shared channel in an LTE system is reused or a grouping-tree resource allocation mode is used to allocate resources for the R-PDSCH. The present disclosure is well applicable to a link between an eNode-B and a relay node, and the resource allocation mode is flexible, the signalling overhead is lowered, therefore, not only the backward compatibility is ensured, but also the problem of mapping and resource allocation of the R-PDSCH is solved.
    • 本公开提供了一种用于R-PDSCH的映射和资源分配方法,包括:当为R-PDCCH分配的资源与为R-PDSCH分配的资源重叠时,R-PDSCH的数据未被映射或发送到超重 资源或要在重叠资源上发送的R-PDSCH的数据被打孔; 在不被R-PDCCH占用的所有或部分资源上映射和发送R-PDSCH的数据; 接收端根据R-PDSCH的映射方法接收数据; 其中,与LTE系统中的共享信道对应的资源分配模式被重新使用,或者使用分组树资源分配模式来分配用于R-PDSCH的资源。 本公开内容适用于eNode-B与中继节点之间的链路,资源分配方式灵活,信令开销下降,不仅保证了向后兼容性,而且还具有映射和 解决了R-PDSCH的资源分配问题。
