Classification: CPC H | IPC H

Claim 0:
1. An electronic device comprising:
first communication circuitry connected to a first antenna and including a first amplifier;
second communication circuitry connected to a second antenna and including a second amplifier;
a transceiver connected to the first communication circuitry and the second communication circuitry;
a processor electrically connected to the transceiver; and
a power supply configured to provide a voltage to one of the first amplifier or the second amplifier in a time domain and electrically connected to the first communication circuitry, the second communication circuitry, 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;
provide, to the first communication circuitry, a first voltage for transmitting a first signal of the first frequency band using the power supply in the first time interval of the plurality of time intervals, the first time interval being an uplink interval of the first radio resource configuration;
control the electronic device to change a configuration of the first communication circuitry to a downlink configuration in a guard period corresponding to a first portion of the second time interval;
control the electronic device to receive a signal of the second frequency band using the second communication circuitry in a first portion of the third time interval;
control the electronic device to change a configuration of the second communication circuitry to an uplink configuration in a guard period of the third time interval corresponding to the guard period of the second time interval;
provide, to the second communication circuitry, a second voltage for transmitting a second signal of the second frequency band using the power supply in a second portion of the third time interval, the second portion of the third time interval being an uplink interval of the second radio resource configuration; and
control the electronic device to receive a signal of the first frequency band using the first communication circuitry in a second portion of the second time interval following the guard period of the second time interval,
wherein the first radio resource configuration and the second radio resource configuration are based on time division duplexing.
