Abstract: An embodiment of the present invention provides a method for processing Physical Downlink Shared Channel (PDSCH) data, to be applied in a system, which supports to adjust uplink and downlink (UL-DL) configurations for Time Division Multiplexing (TDD) dynamically. The method includes: receiving, by a User Equipment (UE), a System Information Block 1 (SIB1); obtaining, by the UE, from the SIB1 a TDD UL-DL configuration employed by the UE in current system, in which the UE doesn't support dynamic service adaption; determining, by the UE, subframe type of subframe 6, wherein the subframe type of subframe 6 is a special subframe or a normal downlink subframe; and determining, by the UE, number of Orthogonal Frequency Division Multiplexing (OFDM) symbols used for PDSCH transmission within subframe 6, based on the subframe type of subframe 6, and processing the PDSCH data of subframe 6. By adopting the technical solution provided by embodiments of the present invention, in a system which supports to dynamically adjust the TDD UL-DL configurations, a UE may be enabled to explicitly learn number of OFDM symbols used for the PDSCH transmission within subframe 6. Meanwhile, the UE and an evolved Node B (eNB) may be enabled not to confuse the number of OFDM symbols used for the PDSCH transmission.

Abstract: A method for transmitting HARQ-ACK information based on transmission diversity is provided. The method includes configuring two component carriers, referred to as Cells, for a User Equipment (UE); when a base station configures the UE to transmit HARQ-ACK information adopting the transmission diversity technique, the base station indicates dynamically whether an other Cell is scheduled in the same subframe via a PDCCH scheduling a PDSCH of one Cell, so as to enable the UE to know the number of Cells scheduled in the same downlink subframe by the base station, and to generate HARQ-ACK information based on the number of Cells. Unnecessary spatial bundling of the HARQ-ACK information may be avoided, unnecessary downlink data retransmission is reduced and throughput of downlink data is improved.
