Method and electronic device for configuring radio frequency setting

An electronic device comprising:

• a plurality of antennas;
• and
• at least one processor configured to:
• receive a first signal from a base station, the first signal indicating that the base station supports carrier aggregation,
• receive a second signal from the base station after the first signal is received, the second signal indicating initiation of the carrier aggregation,
• based on receiving the second signal, change a configuration of a switch, a tuner, or a communication circuit of the electronic device to perform the carrier aggregation, the switch and the tuner connected with at least one antenna of the plurality of antennas,
• communicate with the base station using a plurality of frequency bands based on the changed configuration of the switch, the tuner, or the communication circuit,
• receive a third signal from the base station after the second signal is received, the third signal indicating that the carrier aggregation is inactive,
• based on receiving the third signal, change the configuration of the switch, the tuner, or the communication circuit to perform standalone operation, and
• communicate with the base station using a single frequency band based on the changed configuration of the switch, the turner, or the communication circuit corresponding to the standalone operation.
