1. An electronic device comprising:
a communication processor;
at least one radio frequency integrated circuit (RFIC) connected to the communication processor; and
at least one antenna, each of which is connected to the at least one RFIC via at least one radio frequency front-end (RFFE) circuit, and is configured to transmit or receive a signal corresponding to at least one communication network,
wherein the communication processor is configured to:
identify whether target power corresponding to a primary component carrier (PCC) exceeds maximum transmission power of the electronic device while performing uplink carrier aggregation (CA), and
based on identifying that the target power corresponding to the PCC exceeds the maximum transmission power, set a first transmission power of the PCC to a first power less than the maximum transmission power and set a second transmission power of at least one secondary component carrier (SCC) to a second power less than the first power, based on a first spectral efficiency corresponding to the first transmission power of the PCC and a second spectral efficiency corresponding to the second transmission power of the at least one SCC.
