Patent ID: 8855027

Claim:
A method for transmitting uplink control information in a wireless communication system supporting carrier aggregation and operating in TDD, the method comprising: generating a first set of hybrid automatic repeat request acknowledgements (HARQ-ACKs) associated with a first component carrier (CC); generating a second set of HARQ-ACKs associated with a second CC; and transmitting 4-bit information corresponding to the first set of HARQ-ACKs and the second set of HARQ-ACKs on a physical uplink shared channel (PUSCH), wherein the 4-bit information is given according to a relation including the following table: First CC Second CC HARQ-ACK(0), HARQ- HARQ-ACK(0), HARQ- 4-bit information ACK(1), HARQ-ACK(2) ACK(1), HARQ-ACK(2) o(0), o(1), o(2), o(3) A, A, A A, A, A 1, 1, 1, 1 A, A, N/D A, A, A 1, 0, 1, 1 A, N/D, any A, A, A 0, 1, 1, 1 N/D, any, any A, A, A 0, 0, 1, 1 A, A, A A, A, N/D 1, 1, 1, 0 A, A, N/D A, A, N/D 1, 0, 1, 0 A, N/D, any A, A, N/D 0, 1, 1, 0 N/D, any, any A, A, N/D 0, 0, 1, 0 A, A, A A, N/D, any 1, 1, 0, 1 A, A, N/D A, N/D, any 1, 0, 0, 1 A, N/D, any A, N/D, any 0, 1, 0, 1 N/D, any, any A, N/D, any 0, 0, 0, 1 A, A, A N/D, any, any 1, 1, 0, 0 A, A, N/D N/D, any, any 1, 0, 0, 0 A, N/D, any N/D, any, any 0, 1, 0, 0 N, any, any N/D, any, any 0, 0, 0, 0 D, any, any N/D, any, any 0, 0, 0, 0 wherein A denotes ACK, N denotes NACK (negative ACK), D denotes DTX (discontinuous transmission), N/D denotes NACK or DTX, any represents one of ACK, NACK and DTX, and CC is replaceable by a cell.
