1. An electronic device operable in an environment that includes a wireless base station, the electronic device comprising:
one or more antennas;
one or more sensors configured to generate sensor data indicative of proximity of an external object to the one or more antennas; and
a transceiver configured to transmit uplink (UL) signals over the one or more antennas using a first maximum UL duty cycle; and
one or more processors configured to
generate a radio-frequency exposure (RFE) level based at least on the sensor data and the first maximum UL duty cycle, wherein the transceiver is further configured to transmit information identifying the RFE level to the wireless base station.
