In the present invention, when a user equipment (UE) transmits ACK/NACK information of multiple CCs to a base station (BS), ACK/NACK responses of one CC detected in the order of [ACK, ACK, ACK, ACK], and other ACK/NACK responses of the CC detected in the order of [ACK, DTX, DTX, DTX] are treated to be the same. According to the present invention, control information can be effectively transmitted in a wireless system. 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 4 first ACK (ACKnowledgement)/NACK (Negative ACK)/DTX (Discontinuous Transmission) responses [x(0), x(1), x(2), x(3)] for 4 downlink (DL) transmissions on a first carrier, where x(i), 0≦i≦3, is an ACK/NACK/DTX response for i-th DL transmission on the first carrier;detecting 4 second ACK/NACK/DTX responses [y(0), y(1), y(2), y(3)] for 4 DL transmissions on a second carrier, where y(i), 0≦i≦3, is an ACK/NACK/DTX response for 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, based on [x(0), x(1), x(2), x(3)] and [y(0), y(1), y(2), y(3)]; and transmitting the generated transmission bits on the selected PUCCH resource,wherein when [y(0), y(1), y(2), y(3)] is the same, the same transmission bits are generated for [x(0), x(1), x(2), x(3)]=[ACK, ACK, ACK, ACK] and for [x(0), x(1), x(2), x(3)]=[ACK, DTX, DTX, DTX].2. The method according to claim 1 , wherein when the [y(0) claim 1 , y(1) claim 1 , y(2) claim 1 , y(3)] is the same claim 1 , the same PUCCH resource is selected for [x(0) claim 1 , x(1) claim 1 , x(2) claim 1 , x(3)]=[ACK claim 1 , ACK claim 1 , ACK claim 1 , ACK] and for [x(0) claim 1 , x(1) claim 1 , x(2) claim 1 , x(3)]=[ACK claim 1 , DTX claim 1 , DTX claim 1 , DTX].4. The method according to claim 3 , wherein the same PUCCH ...
