Abstract: A method of operating an electronic device is provided. The method of operating an electronic device includes determining whether a multi-frequency band connection is established, when a result of the determination is that the multi-frequency band connection is established, identifying a frequency band transmitting control information from among connected multi-frequency bands, acquiring communication state information of the identified frequency band transmitting the control information, determining an antenna mode based on the acquired communication state information, and configuring at least one antenna based on the determined antenna mode.

Abstract: An electronic device is provided. The electronic device includes first and second housings, a memory, an application processor, a communication processor, a Radio Frequency Integrated Circuit (RFIC) connected with the communication processor, and a plurality of antennas each connected with the RFIC through a Radio Frequency Front-End (RFFE) circuit. The communication processor may identify a change in an antenna-related setting for the plurality of antennas, identify frequency band information about a signal being communicated through at least one antenna among the plurality of antennas, in response to the change in the antenna-related setting, identify folding state information between the first housing and the second housing received from the application processor, identify, from the memory, a transmission power-related setting value set corresponding to the identified frequency band information, the folding state information, and an event related to the communication processor, and adjust a power of a transmission signal.
