Abstract:
1. A method of transmitting signals using multiple component carriers at a communication apparatus in a wireless communication system, the method comprising: determining, per component carrier, 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; and 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, wherein, 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, transmission power of at least one physical uplink shared channel (PUSCH) among the plurality of channels is adjusted in such a way that an adjusted total transmission power over the multiple component carriers does not exceed the total maximum transmission power.
