Provided are a method and an apparatus for transmitting an ACK/NACK in a wireless communication system. A first cell group and a second cell group are configured, wherein the first cell group comprises a primary cell capable of transmitting an uplink (UL) control channel, and the second cell group comprises a secondary cell capable of transmitting the UL control channel. The apparatus receives a plurality of downlink (DL) transmission blocks from a plurality of cells belonging to the first cell group and the second cell group, and generates an ACK/NACK payload according to the priority of a corresponding cell from among the plurality of ACK/NACK bits corresponding to the plurality of DL transmission blocks. |
