Classification: CPC H | IPC H

Claim 8:
9. An electronic device comprising:
a first communication circuit connected to a first antenna and including a first amplifier;
a second communication circuit connected to a second antenna and including a second amplifier;
a processor connected to the first communication circuit and the second communication circuit; and
a power supply configured to provide one voltage in a time domain and electrically connected to the first communication circuit, the second communication circuit, and the processor,
wherein the processor is configured to:
determine a first radio resource configuration of a first frequency band and a second radio resource configuration of a second frequency band for a plurality of time intervals corresponding to equal subframes such that uplink timing of the first frequency band and the second frequency band do not overlap each other in a time domain, the plurality of time intervals including a first time interval, a second time interval following the first time interval, and a third time interval overlapping a portion of the first time interval and a portion of the second time interval;
control the electronic device to transmit, using the first communication circuit, a first signal of the first frequency band in the first time interval;
control the electronic device to receive, using the second communication circuit, a signal of the second frequency band in the first time interval;
control the electronic device to change a configuration of the first communication circuit to a downlink configuration in a guard period corresponding to a first portion of the second time interval and change a configuration of the second communication circuit to an uplink configuration in a first portion of the third time interval corresponding to the guard period;
control the electronic device to transmit, using the second communication circuit, a second signal of the second frequency band in a second portion of the third time interval; and
control the electronic device to receive, using the first communication circuit, a signal of the first frequency band in a second portion of the second time interval;
wherein the power supply is configured to:
supply, to the first communication circuit, a first voltage for transmitting the first signal in the first time interval indicated by the first radio resource configuration; and
supply, to the second communication circuit, a second voltage for transmitting the second signal in the second portion of the third time interval indicated by the second radio resource configuration, that does not overlap the first time interval, and
wherein the first radio resource configuration and the second radio resource configuration are based on time division duplexing.
