Abstract: A method is described for transmitting signals at a communication apparatus in a wireless communication system supporting a plurality of component carriers. 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. A predefined transmission power determination scheme is used to determine the transmission power of the PUSCH with the UCI, and determine the transmission power of the PUSCH without the UCI. If a total transmission power of the PUSCH with the UCI and the PUSCH without the UCI exceeds a value corresponding to a maximum transmission power configured for the communication apparatus, the determined transmission power of the PUSCH without UCI is adjusted while maintaining the determined transmission power of the PUSCH with the UCI.
