Patent ID: 8811249

Claim:
A method for transmitting signals at a communication apparatus in a wireless communication system, the method comprising: transmitting, simultaneously, a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH), wherein a transmission power of the PUCCH and a transmission power of the PUSCH are determined according to a predefined transmission power determination rule, wherein the predefined transmission power determination rule comprises: determining a transmission, power of the PUCCH; and determining a transmission, power of the PUSCH, wherein, if a total transmission power of the PUCCH and the PUSCH exceeds a value corresponding to a maximum transmission power configured for the communication apparatus, the determined transmission power of the PUSCH is reduced while maintaining the determined transmission power of the PUCCH, and wherein the PUCCH is transmitted based on the determined transmission power of the PUCCH and the PUSCH is transmitted based on the reduced transmission power of the PUSCH.
