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: A method for transmitting Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) feedback information is provided. The method includes obtaining HARQ-ACK feedback information, a total number of bits of which is less than or equal to four through performing group bundling on the HARQ-ACK feedback information of all sub-frames in a current HARQ-ACK bundling window of two Component Carriers (CCs), determining a number of Physical Uplink Control Channel (PUCCH) resources provided for transmission of the HARQ-ACK feedback information according to data transmission modes of the two CCs, and a number of elements in the bundling window, and transmitting the HARQ-ACK feedback information after the group bundling to a base station on PUCCH channel resources adopting a PUCCH format 1b of channel selection according to the PUCCH channel resources mapped from the HARQ-ACK feedback information after the group bundling and modulation symbols.
