Claim:
1. A method for transmitting uplink control information by a user equipment (UE) in a wireless communication system supporting carrier aggregation, the UE being configured with a plurality of cells including a first cell and a second cell and configured to transmit a hybrid automatic repeat request-acknowledgment (HARQ-ACK) response based on channel selection, the first cell and the second cell having different uplink-downlink (UL-DL) configurations and operating in time division duplex (TDD), the method comprising: determining a value M as a largest value of M1 or M2, M1 being a value according to an UL-DL configuration of the first cell and M2 being a value according to an UL-DL configuration of the second cell; determining HARQ-ACK responses for the first cell and the second cell based on the value M; determining bit values and a physical uplink control channel (PUCCH) resource corresponding to the determined HARQ-ACK responses; and transmitting the bit values using the PUCCH resource in an uplink subframe.
