Claim:
A method for transmitting uplink control information in a wireless communication system supporting multiple carriers, the method comprising: reserving one or more channel selection resources for transmission of the uplink control information; receiving scheduling information for one or more uplink data channels, wherein the one or more uplink data channels are scheduled to be transmitted in the same time domain resources as the reserved channel selection resources; determining one uplink data channel on which the uplink control information is multiplexed, among the one or more uplink data channels; puncturing one or more resource element regions of the one or more uplink data channels, wherein the one or more resource element regions correspond respectively to the one or more channel selection resources reserved for transmission of the uplink control information on the one unlink data channel; and multiplexing the uplink control information in the punctured resource element regions on the determined one uplink data channel, and transmitting the multiplexed uplink control information, wherein the unlink control information is mapped to at least a portion of the punctured resource element regions, and a sequence indicating that the unlink control information is not transmitted is mapped to a remaining portion of the punctured resource element regions.
