Abstract: A method is provided for generating Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a user equipment in a wireless communication system. The user equipment receives a plurality of codewords corresponding to data blocks through a plurality of downlink carriers from a base station, wherein each of the plurality of downlink carriers carries one or more codewords. The user equipment generates the ACK/NACK information by concatenating ACK/NACK bits corresponding to the plurality of codewords. When a corresponding downlink carrier carries two or more codewords, the ACK/NACK bits corresponding to the two or more codewords associated with the corresponding downlink carrier are concatenated in accordance with an index order of a corresponding data block. The ACK/NACK bits concatenated in accordance with the index order of the corresponding data block associated with each of the downlink carriers are concatenated again in accordance with an index order of a corresponding downlink carrier.

Abstract: A method and wireless station for receiving signals. The wireless station receives, from a base station, a control signal on a first subframe indicated as a downlink (DL) subframe by a time division duplex (TDD) uplink-downlink (UL-DL) subframe configuration. The control signal includes first information indicating that at least one UL subframe indicated by the TDD UL-DL subframe configuration is reconfigured as a TDD DL subframe. The wireless station receives, from the base station, DL data on a second subframe which was indicated as a TDD UL subframe by the TDD UL-DL subframe configuration but is currently reconfigured as a TDD DL subframe by the control signal. The wireless station transmits, to the base station, UL data on a TDD UL subframe except for being reconfigured as the TDD DL subframe by the control signal.
