A method for transmitting signals at a user equipment in a wireless communication system, characterized in that it comprises: transmitting, simultaneously, a physical uplink control channel, PUCCH, a physical uplink shared channel, PUSCH, with uplink control information, UCI, and a PUSCH without the UCI using a plurality of component carriers, wherein a transmission power of the PUCCH, a transmission power of the PUSCH with the UCI and a transmission power of the PUSCH without the UCI are determined according to a predefined transmission power determination rule, wherein the predefined transmission power determination rule comprises: determining the transmission power of the PUCCH; and determining the transmission power of the PUSCH with the UCI and the transmission power of the PUSCH without the UCI, wherein, if a sum transmission power of the PUCCH, the PUSCH with the UCI and the PUSCH without the UCI exceeds a maximum transmission power configured for the user equipment, the determined transmission power of the PUSCH without the UCI is reduced while maintaining the determined transmission powers of the PUCCH and the PUSCH with the UCI, wherein the PUCCH is transmitted based on the determined transmission power of the PUCCH, the PUSCH with the UCI is transmitted based on the determined transmission power of the PUSCH with the UCI, and the PUSCH without the UCI is transmitted based on the reduced transmission power of the PUSCH without the UCI. transmitting, simultaneously, a physical uplink control channel, PUCCH, a physical uplink shared channel, PUSCH, with uplink control information, UCI, and a PUSCH without the UCI using a plurality of component carriers, wherein a transmission power of the PUCCH, a transmission power of the PUSCH with the UCI and a transmission power of the PUSCH without the UCI are determined according to a predefined transmission power determination rule, wherein the predefined transmission power determination rule comprises: determining the transmission power of the PUCCH; and determining the transmission power of the PUSCH with the UCI and the transmission power of the PUSCH without the UCI, wherein, if a sum transmission power of the PUCCH, the PUSCH with the UCI and the PUSCH without the UCI exceeds a maximum transmission power configured for the user equipment, the determined transmission power of the PUSCH without the UCI is reduced while maintaining the determined transmission powers of the PUCCH and the PUSCH with the UCI, wherein the PUCCH is transmitted based on the determined transmission power of the PUCCH, the PUSCH with the UCI is transmitted based on the determined transmission power of the PUSCH with the UCI, and the PUSCH without the UCI is transmitted based on the reduced transmission power of the PUSCH without the UCI. determining the transmission power of the PUCCH; and determining the transmission power of the PUSCH with the UCI and the transmission power of the PUSCH without the UCI, wherein, if a sum transmission power of the PUCCH, the PUSCH with the UCI and the PUSCH without the UCI exceeds a maximum transmission power configured for the user equipment, the determined transmission power of the PUSCH without the UCI is reduced while maintaining the determined transmission powers of the PUCCH and the PUSCH with the UCI, wherein the PUCCH is transmitted based on the determined transmission power of the PUCCH, the PUSCH with the UCI is transmitted based on the determined transmission power of the PUSCH with the UCI, and the PUSCH without the UCI is transmitted based on the reduced transmission power of the PUSCH without the UCI.
