Abstract: A method and user equipment (UE) for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. The UE determines a Physical Uplink Control Channel (PUCCH) format and a PUCCH resource through which ACK/NACK information for downlink transmission in a downlink subframe set including M (M>1) downlink subframes is to be transmitted. The UE transmits the ACK/NACK information using the PUCCH format and the PUCCH resource in one uplink subframe. More than one serving cell is configured for the UE and the more than one serving cell includes one Primary Cell (PCell) and at least one Secondary Cell (SCell). The ACK/NACK information is transmitted using a PUCCH format 1b, when the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set.
