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.

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.

Abstract: A method for allocating a physical hybrid ARQ indicator channel (PHICH) is discussed. The method includes allocating a CDM group according to a cyclic prefix type in consideration of a ratio of the numbers of necessary CDM groups according to spreading factors, and allocating a PHICH to the allocated CDM group. The PHICH includes an ACK/NACK signal multiplexed by code division multiplexing (CDM). Therefore, resources for PHICH transmission are efficiently allocated and a transmission structure can be maintained irrespective of a spreading factor.
