An electronic device according to an embodiment may comprise: at least one antenna; a first communication circuit connected to the at least one antenna and configured to communicate using a long term evolution (LTE) signal in a licensed band and an LTE signal in an unlicensed band; and a second communication circuit connected to the first communication circuit and at least a part of the at least one antenna, and configured to communicate using a Wi-Fi signal in the unlicensed band. The first communication circuit is configured to, acquire, from the second communication circuit, information on state of a channel in the unlicensed band associated with the first communication circuit and the second communication circuit, and determine a time interval associated with processing of the LTE signal in the unlicensed band. Various other embodiments recognized from the specification are also possible.
