Claim Text:
1. A method for transmitting, by a user equipment (UE), uplink control information to a base station (BS) in a wireless communication system, the method comprising: detecting a first ACKnowledgement (ACK)/Negative ACK (NACK)/Discontinuous Transmission (DTX) response sequence [x(0), x(1), x(2), x(3)] for 4 downlink (DL) transmissions on a first carrier, where x(i) is an ACK/NACK/DTX response for an i-th DL transmission on the first carrier; detecting a second ACK/NACK/DTX response sequence [y(0), y(1), y(2), y(3)] for 4 DL transmissions on a second carrier, where y(i) is an ACK/NACK/DTX response for an i-th DL transmission on the second carrier; performing channel selection, by selecting one of a plurality of physical uplink control channel (PUCCH) resources and generating transmission bits for ACK/NACK information of the first and second carriers, based on the first and second ACK/NACK/DTX response sequences; and transmitting the generated transmission bits on the selected PUCCH resource, wherein the channel selection is performed according to a mapping table and the manning table includes a mapping relationship shown in the following table:
