Abstract:
1. A method for transmitting signals using a plurality of component carriers by a communication apparatus in a wireless communication system, the method comprising: determining, per each of the component carriers, a transmission power of at least one channel for simultaneous transmission, in such a way that a total transmission power of the at least one channel does not exceed a maximum transmission power configured for a corresponding component carrier; checking whether a total transmission power of a plurality of channels over the multiple component carriers for the simultaneous transmission exceeds a total maximum transmission power configured for the communication apparatus or not, the plurality of channels including a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH) with uplink control information (UCI), and a PUSCH without the UCI; and if the total transmission power of the plurality of channels over the multiple component carriers exceeds the total maximum transmission power configured for the communication apparatus, adjusting a transmission power of the PUSCH without the UCI from among the plurality of channels so that an adjusted total transmission power over the plurality of component carriers does not exceed the total maximum transmission power.
