Abstract: In an electronic device and operation method thereof according to various embodiments, the electronic device may include a plurality of antennas. The electronic device may include a communication circuit electrically connected to the plural antennas. The electronic device may include a communication processor, comprising at least one processor, comprising processing circuitry, operably connected to the communication circuit. At least one processor, individually and/or collectively, may be configured to control the electronic device to: receive information indicating a combination of frequency bands to be used for cellular communication from a cellular network; based on the combination of frequency bands being a combination of designated frequency bands, transmit, to the cellular network, user equipment (UE) capability information including information for changing an operation related to transmission of a reference signal in a first frequency band among the combination of frequency bands; receive, from the cellular network, a signal including parameters related to transmission of a reference signal configured based on the information for changing the operation related to transmission of a reference signal; and transmit a reference signal based on the parameters related to transmission of a reference signal.

Abstract: According to an embodiment, an electronic device may comprise: memory storing instructions and at least one processor, comprising processing circuitry, individually and/or collectively. The instructions, when executed by at least one processor, cause the electronic device to: identify a position of the electronic device and at least one satellite from a GPS signal based on identifying a first event, identify whether a value based on a relative angle between a trajectory axis corresponding to the at least one satellite and the electronic device meets a first condition, identify whether a value based on a relative distance between the electronic device and the at least one satellite meets a second condition based on identifying that the value based on the relative angle does not meet the first condition, set a first power lower than a third power to a transmission power of a transmission signal corresponding to satellite communication based on identifying that the value based on the relative distance meets the second condition, and set a third power to a transmission power of a transmission signal corresponding to satellite communication based on identifying that the value based on the relative distance does not meet the second condition.

Abstract: An electronic device, which may be a dual-mode user equipment (UE), communicates with a first network and a second network. The first network may be a legacy network. The second network may be a 5G or 6G network. Transmission by the electronic device of reference signals to the second network may interfere reception at the electronic device of signals from the first network. Methods and devices are provided for avoiding interference when using the first and second networks.
