    Abstract: An electronic device is provided. The electronic device includes a communication processor, at least one Radio Frequency Integrated Circuit (RFIC) connected thereto, and an antenna connected through the at least one RFIC and configured to transmit and receive a signal corresponding to at least one communication network. The communication processor is configured to control the electronic device to receive a signal corresponding to a first communication network from a first base station corresponding to the first communication network supporting a first frequency band through the antenna, identify information related to a second communication network supporting a second frequency band including at least a portion of the first frequency band, identify a time interval allocated for transmission of data corresponding to the second communication network on the basis of the information related to the second communication network, and operate in a sleep state in the identified time interval.
