Abstract
Disclosed are a method and device for R-PDCCH transmission in the scenario of carrier aggregation. By way of applying the technical solution of the embodiments of the present invention, multi-carrier aggregation transmission is supported between the relay node and the base station. The base station sends a component carrier carrying the R-PDCCH to the relay node and schedules the resources in each component carrier by way of the R-PDCCH carried in the component carrier. Thus what is achieved is that the base station communicates with the relay node by way of a plurality of aggregated component carriers, enabling the link transmission resources between the base station and the relay node to support multi-carrier PDCCH scheduling, improving the transmitting capacity of the link between the base station and the relay node, and improving the system performance.
