摘要： A resource allocation method and apparatus for a relay node under the condition of carrier aggregation are disclosed in the embodiments of the present invention. By applying the technical solution of the embodiments of the present invention, a relay node can determine information of cells, which are currently available for allocation, of a Un interface, and report the information to an eNB, so that the eNB can allocate corresponding Un interface resources for the relay node according to the information. Thus the eNB side can accurately obtain the information of the cell resources, which are available for allocation and currently correspond to the relay node, of the Un interface. Thus the problem is solved that the relay node cannot properly work under the condition of the carrier aggregation caused by the mismatching between the Un interface resources directly allocated by the eNB and the relay node in the prior art.
