Abstract: A Physical Downlink Shared CHannel (PDSCH) transmission data method is provided. A User Equipment (UE) receives cross-carrier scheduling information in a PDCCH of a cell for scheduling. The cross-carrier scheduling information carries scheduling information indicating at least one PDSCH in at least one sub-frame of a cell being scheduled in cross-carrier scheduling. The UE processes data of PDSCH corresponding to the instruction according to received cross-carrier scheduling information. The UE sends a HARQ-ACK message to a base station according to the processed result. The peak rate of the UE is increased, and the requirement for higher throughput of the UE is satisfied.
