Abstract: An operation method of an electronic device includes determining whether a first communication module based on a first radio access technology (RAT) and a second communication module based on a second RAT operate in a connected state; determining whether a combination of a first band used by the first communication module and a second band used by the second communication module is a combination causing interference; and if the combination of the first band and the second band is a combination causing interference, transmitting a signal requesting to change one of the first band or the second band. The interference is caused by at least one transmission signal of the first RAT or at least one other signal derived from the at least one transmission signal.
