Patent ID: 7987403

Claim:
A method of encoding feedback signals, comprising: encoding feedback signals of three carriers to output a bit sequence; wherein encoding the feedback signals of the three carriers to output the bit sequence comprises: mapping the feedback signals of the three carriers into the bit sequence according to a mapping relationship as shown in the following table: ACK-DTX-DTX 1 1 1 1 1 1 1 1 1 1 NACK-DTX-DTX 0 0 0 0 0 0 0 0 0 0 DTX-ACK-DTX 1 1 1 1 1 0 0 0 0 0 DTX-NACK-DTX 0 0 0 0 0 1 1 1 1 1 DTX-DTX-ACK 1 1 0 0 0 1 1 0 0 0 DTX-DTX-NACK 0 0 1 1 1 0 0 1 1 1 ACK-ACK-DTX 1 0 1 0 1 0 1 0 1 0 ACK-NACK-DTX 1 1 0 0 1 1 0 0 1 1 NACK-ACK-DTX 0 0 1 1 0 0 1 1 0 0 NACK-NACK-DTX 0 1 0 1 0 1 0 1 0 1 ACK-DTX-ACK 1 0 1 1 0 1 1 0 0 1 ACK-DTX-NACK 0 1 0 1 1 0 1 0 0 1 NACK-DTX-ACK 0 0 0 1 1 1 1 0 1 0 NACK-DTX-NACK 1 0 0 1 1 1 0 1 0 0 DTX-ACK-ACK 0 1 1 1 0 1 0 0 1 0 DTX-ACK-NACK 1 0 1 0 0 1 0 1 1 0 DTX-NACK-ACK 0 1 1 0 0 0 1 0 1 1 DTX-NACK-NACK 0 0 0 0 1 0 1 0 1 1 ACK-ACK-ACK 1 1 0 1 0 0 1 1 1 0 ACK-ACK-NACK 0 1 1 0 1 1 1 1 0 0 ACK-NACK-ACK 1 0 0 1 0 0 0 0 1 1 ACK-NACK-NACK 0 0 1 0 1 1 0 0 0 1 NACK-ACK-ACK 1 1 1 0 0 0 0 1 0 1 NACK-ACK-NACK 0 1 0 0 1 0 0 1 1 0 NACK-NACK-ACK 1 0 0 0 1 0 1 1 0 1 NACK-NACK-NACK 1 1 1 1 0 1 0 1 0 0 wherein DTX represents discontinuous transmission, ACK represents acknowledgement, NACK represents negative acknowledgement.
