Electronic Devices with Time Division Radio-Frequency Communication and Sensing

An electronic device may include wireless circuitry with a radio that conveys wireless data with a wireless base station using antennas according to a communication schedule and that performs sensing using the antennas. The sensing may involve transmission of sensing signals and reception of reflected signals during sensing periods. Control circuitry may adjust timing of the sensing periods, based on network configuration information and the current sensing requirements of the device, to align with scheduled inactive times for the radio. In this way, the radio may perform radio-frequency sensing for use in adjusting wireless transmissions to satisfy radio-frequency exposure requirements without substantially disrupting wireless data communications.
