To perform a first communication with a first base station through the first communication circuit by using a first frequency band, perform a second communication with a second base station through the second communication circuit by using a second frequency band, determine whether the first communication interferes with the second communication, and transmit, to the second base station for the second communication on the basis of the determination result, a request for using a third frequency band, which is different from the second frequency band in at least one from among bandwidth, center frequency, or sub-carrier spacing (SCS). Other various embodiments are possible.

Electronic device, and method for reducing self-interference due to dual uplink operation

A portable communication device is provided. The communication device includes a first communication circuitry configured to perform communication using a first frequency band, a second communication circuitry configured to perform communication using a second frequency band, and at least one processor configured to receive a reference signal transmitted from a first external electronic device using the first communication circuitry, and when a received power corresponding to the reference signal belongs to a specified first range, communicate with at least one external electronic device through multiple cellular connections by transmitting a first signal of the first frequency band to the first external electronic device through a first cellular connection established using the first communication circuitry and substantially concurrently transmitting a second signal of the second frequency band to a second external electronic device through a second cellular connection established using the second communication circuitry.

Apparatus and method for selecting uplink based on communication state

An electronic device includes: an antenna; a communication circuit connected with the antenna; and one or more processors, wherein the one or more processors are configured to: identify a second amount of power corresponding to a second output signal outputted through the antenna for a second time using the communication circuit, the operation of identifying the second amount of power comprising an operation of identifying a second electromagnetic wave absorption rate corresponding to the second amount of power; determine a maximum output power for a third output signal to be outputted through the antenna according to a difference between a target electromagnetic wave absorption rate and the second electromagnetic absorption rate; and output the third output signal through the antenna based at least one the maximum output power.

Method for controlling power and electronic device thereof

Various examples of the present invention relate to a device and a method for improving wireless communication performance in an electronic device. The electronic device comprises multiple antennas, a communication circuit connected to the multiple antennas, a connector, and at least one processor, wherein the processor checks whether a wired cable is connected through the connector and, if the wired cable is connected through the connector, can perform control such that communication using the multiple antennas corresponding to the connection of the wired cable is performed. Other examples can be possible.
