Claim:
1. A method for transmitting uplink control information by a user equipment in a wireless communication system supporting carrier aggregation and operating in time division duplex (TDD), the user equipment being configured with a first component carrier (CC) and a second CC having different uplink-downlink configurations and the user equipment being configured to transmit a hybrid automatic repeat request-acknowledgement (HARQ-ACK) response based on channel selection, the method comprising: determining HARQ-ACK bits for the first CC and the second CC; and transmitting the determined HARQ-ACK bits through a physical uplink shared channel (PUSCH) in an uplink subframe, wherein one or more HARQ-ACK bits for the first CC, and one or more HARQ-ACK bits for the second CC are determined, respectively, based on min (M1, W) and min (M2, W), when a value W indicated by a downlink assignment index in an uplink grant corresponding to the PUSCH is 1 or 2 and wherein min (A, B) represents a smallest number from A and B, M1 represents a number of downlink subframes corresponding to the uplink subframe on the first CC, and M2 represents a number of downlink subframes corresponding to the uplink subframe on the second CC.
