Abstract: A method and communication apparatus for transmitting signals in a wireless communication system supporting a plurality of component carriers are described. A physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH) with uplink control information (UCI) and a PUSCH without the UCI are simultaneously transmitted using the plurality of component carriers. If a total transmission power of the PUCCH, the PUSCH with the UCI and the PUSCH without the UCI exceeds a value corresponding to a maximum transmission power, a transmission power determined for the PUSCH without the UCI is reduced while maintaining transmission powers determined for the PUCCH and the PUSCH with the UCI. The PUCCH and the PUSCH with the UCI are transmitted based on the maintained determined transmission powers, and the PUSCH without the UCI is transmitted based on the reduced transmission power.
