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 of acquiring information on a resource region for transmitting PHICH and a method of receiving PDCCH using the same are disclosed. The resource region for transmitting the PHICH can be specified by first information corresponding to the per-sub frame PHICH number and second information corresponding to a duration of the PHICH within the subframe. The first Information can be specified into a form resulting from multiplying a predetermined basic number by a specific constant. And, the specific constant can be transmitted via PBCH. Moreover, the second information can be acquired from the PBCH as well.
