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.

Abstract: The present disclosure relates to an apparatus and a method for controlling power consumption for monitoring a sensor state in an electronic device. The electronic device can stop checking the state of at least one sensor until a radio resource control (RRC) connection is maintained, and a cumulative electromagnetic wave specific absorption rate (SAR) reaches a preset threshold value (SAR_threshold). The cumulative electromagnetic wave specific absorption rate may be an electromagnetic wave specific absorption rate accumulated by transmission power transmitted within a time period corresponding to a time slot using a specific frequency band.

Abstract: According to various embodiments, an electronic device may comprise: an RF circuit configured for cellular data communication, a plurality of antennas connected to the RF circuit, a Wi-Fi module comprising Wi-Fi circuitry, and at least one processor. The at least one processor may be configured to provide a first indication indicating activation of cellular data communication based on a first antenna among the plurality of antennas being used for transmission. A distance between the first antenna and a Wi-Fi antenna corresponding to the Wi-Fi module may be equal to or less than a first value. The Wi-Fi module may be configured to perform a back-off operation on transmission power of a Wi-Fi RF signal based on reception of the first indication. The at least one processor may be further configured to refrain from providing the first indication, based on a second antenna from which distance to the Wi-Fi antenna exceeds the first value among the plurality of antennas being used for transmission.
