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.

METHODS AND APPARATUS FOR RECEPTION POINT POSITIONING MEASUREMENTS

Positioning of a user equipment (UE) is supported using reception points (RPs) that receive uplink sounding reference signals (SRS) from the UE. The RPs may measure signal strengths of received SRS that are used to determine path loss reference values that are provided to the UE for configurating subsequent SRS. The UE may report a plurality of RxTx time difference measurements with respect to a single PRS for the SRS transmitted to a plurality of RPs. The RPs may provide an Rx time for received SRS, which is used to generate a RxTx time different measurement for asymmetric round trip time (RTT) if the RP and TRP clocks are synchronized. The RPs may provide an RxRx time difference measurement for a time of reception of PRS and SRS if the RP and TRP clocks are synchronized. A location server determines a position of the UE using different positioning measurements.
