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 channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A-10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least one of an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of a minimum Hamming distance.
