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.

Abstract: An apparatus and a method for feeding back data receiving status, applied to a system, are provided. The method includes sequencing, by a User Equipment (UE), downlink subframes for transmitting data with respect to each Component Carrier (CC), generating receiving status feedback information for the first X downlink subframes with respect to each CC according to the result of the sequencing, where X≤M, wherein M is the number of downlink subframes on each CC, and transmitting the receiving status feedback information generated with respect to each CC to a base station. Accordingly, the UE will not misinterpret the receiving status for the downlink subframes due to inconsistencies with the base station between transmitting and receiving feedback. This affects the Hybrid Automatic Repeat Request (HARQ) transmission, saves the uplink overheads occupied by the receiving status feedback information, and increases the uplink coverage area.
