Near field user detection using a radar signal analysis associated with a user equipment

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment receives a sliding window of measurements associated with a radar signal transmitted by the UE; determines that a user is within a threshold distance of the UE, wherein the threshold distance is determined to be a first distance when an energy measurement, associated with the radar signal, indicates an energy reduction satisfying a threshold energy reduction, or wherein the threshold distance is determined to be a second distance when the sliding window of measurements indicates an amount of energy variation satisfying a threshold amount of energy variation associated with the radar signal; and performs, based at least in part on determining that the user is within the threshold distance, an action associated with a communication signal of the UE. Numerous other aspects are provided.
