    • A method and system for transmitting a relay link control channel are disclosed for realizing the mapping and transmission of a control channel on a link from an eNode-B to a relay node. In the present invention, in a frequency division multiplex mode, control information is carried by one or more resource blocks in the frequency direction and the universal set of OFDM symbols available to a relay link in a subframe in the time direction; in a time division and frequency division multiplex mode, control information is carried by one or more resource blocks in the frequency direction and a subset of OFDM symbols available to a relay link in a subframe in the time direction; in a time division multiplex mode, control information is carried by all the resource blocks in the frequency direction and a subset of OFDM symbols available to a relay link in a subframe in the time direction; and the mapping of the control channel includes mapping in the time direction and/or the frequency direction. The present invention has backward compatibility and can obtain frequency diversity again. The time division multiplex mode can save power consumption, and the frequency division multiplex mode and the time division and frequency division multiplex mode have the advantages of flexible service scheduling.

    • 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.
