Abstract: According to various embodiments, an electronic device may comprise: a memory, a communication processor, at least one radio frequency integrated circuit (RFIC), and a plurality of antennas each connected with the at least one RFIC. The communication processor may be configured to: identify a change in an antenna-related setting for the plurality of antennas, identify frequency band information corresponding to 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, from the memory, a transmit power-related setting value set corresponding to the identified frequency band information and an event related to the communication processor, and control the electronic device to adjust a power of a transmission signal to be transmitted through at least one antenna among the plurality of antennas based on the identified transmit power-related setting value.

Abstract: According to various embodiments, an electronic device may include: at least one antenna, and at least one processor, wherein the at least one processor is configured to: identify a first frequency for wireless communication through at least one of the at least one antenna, select, based on the first frequency, at least one first radio frequency (RF) path among multiple RF paths positioned between the at least one antenna and the processor, identify an error associated with the at least one first RF path, based on an error associated with the at least one first RF path being identified, stop using the at least one first RF path, and control a communication circuit positioned in at least one second RF path among the multiple RF paths such that a baseband signal is converted into an RF signal, wherein the RF signal is configured to be radiated outwards through at least one antenna corresponding to the at least one second RF path among the at least one antenna. Various other embodiments are also possible.

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.
