Abstract:
1. A method of transmitting uplink control information at a communication apparatus configured with a plurality of cells in a wireless communication system, the method comprising: receiving at least one of one or more Physical Downlink Control Channel (PDCCH) signals and one or more Physical Downlink Shared Channel (PDSCH) signals through one or more subframes on the plurality of cells; and generating entire received response information of the one or more PDCCH signals and the one or more PDSCH signals, wherein multiple received response information contained in the entire received response information are generated per cell and per subframe, wherein, if there is a subframe in which a plurality of transport blocks (TBs) are received in a cell configured to support transmission of the multiple transport blocks (TBs), DTX (discontinuous transmission) state and all negative acknowledgement (NACK) state are mapped to the same bit values for the cell and the subframe, and if there is a subframe in which only one transport block (TB) is received in a cell configured to support transmission of multiple transport blocks (TBs), DTX state and all NACK state are mapped to different bit values for the cell and the subframe.
