Abstract
An electronic device and method for supporting carrier aggregation are provided. An electronic device may include a communication circuit including a plurality of local oscillators; and a processor configured to determine an operation mode of at least one local oscillator among the plurality of oscillators based on at least one of a number of uplink carriers and a number of downlink carriers; and control the at least one local oscillator to operate based on the determined operation mode.
Claims6
An electronic device, comprising:
- a first oscillator;
- a second oscillator;
- a third oscillator;
- a communication circuit electrically connected to the first oscillator, the second oscillator, and the third oscillator, and comprises:
- a first signal terminal for communication using a first carrier frequency band of a first frequency band,
- a second signal terminal for communication using a second carrier frequency band of the first frequency band,
- a third signal terminal for communication using a third carrier frequency band of the first frequency band,
- a fourth signal terminal for communication using a first carrier frequency band of a second frequency band,
- a fifth signal terminal for communication using a second carrier frequency band of the second frequency band, and
- a sixth signal terminal for communication using a third carrier frequency band of the second frequency band;
- a switch including:
- a first terminal,
- a second terminal electronically connected to the third signal terminal, and
- a third terminal electrically connected to the sixth terminal,
- wherein the switch selectively connects the first terminal to the second terminal or the third terminal;
- at least one antenna electrically connected to the first signal terminal, the second signal terminal, the fourth signal terminal, the fifth signal terminal, and the first terminal;
- and
- a control circuit,
- wherein, when communication with an external electronic device is to be performed using two or less carrier frequency bands in one of the first frequency band and the second frequency band, the control circuit is configured to communicate with the external electronic device using the first carrier frequency band or the second carrier frequency band of the one frequency band, and
- wherein, when communication with the external electronic device is to be performed using three or more carrier frequency bands in one of the first frequency band and the second frequency band, the control circuit is further configured to:
- connect the first terminal to the second terminal or the third terminal using the switch, and
- communicate with the external electronic device using the first carrier frequency band, the second carrier frequency band, and the third carrier frequency band of the one frequency band.
