Method for transmitting control information and apparatus for same

A user equipment (UE) configured to transmit uplink control information in a wireless communication system using time division duplex (TDD), the UE being configured with a first component carrier (CC) and a second CC having different uplink-downlink configurations, the UE comprising:

• a radio frequency (RF) unit;
• and
• a processor coupled to the RF unit and configured to:
• determine hybrid automatic repeat request acknowledgement (HARQ-ACK) information for the first CC based on min (M1, W);
• determine HARQ-ACK information for the second CC based on min (M2, W);
• and
• transmit bit information corresponding to the HARQ-ACK information for the first and second CCs through a physical uplink shared channel (PUSCH) in an uplink subframe,
• wherein min (A, B) represents a smallest number from A and B, W represents an uplink downlink assignment index (UL DAI) value indicated by an uplink grant for the PUSCH, 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.
