FIELD: radio engineering, communication.
SUBSTANCE: present invention relates to wireless mobile communication and can be used in links between a base station eNode-B and a relay node. The technical result is flexible resource allocation, low overhead transmission losses, thereby ensuring not only backward compatibility, but also solving the problem of mapping and resource allocation for the R-PDSCH. When resources allocated for an R-PDCCH overlap with resources allocated for the R-PDSCH, data of the R-PDSCH are not mapped or sent on over-lapped resources, or the data of the R-PDSCH to be sent on the over-lapped resources are punctured; the data of the R-PDSCH are mapped and sent on all or part of the 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 used or a grouping-tree resource allocation mode is used to allocate resources for the R-PDSCH.
EFFECT: invention can be successfully applied, wherein the resource allocation mode is flexible and overhead transmission losses are lowered.
