Abstract
In an aspect, a user equipment (UE) determines a mutual coupling signal associated with a transmit antenna and a receive antenna, determines a mutual coupling difference between the mutual coupling signal and a reference signal, determines a beat signal difference between a current beat signal and a previous beat signal, and determines an amount of micro-motion that is present within a near field. The UE determines whether human tissue is present within the near field based on the mutual coupling difference and the amount of micro-motion. Based on determining that the human tissue is present within the near field, the UE determines an amount of radio frequency exposure associated with the human tissue. Based on determining that the amount of radio frequency exposure exceeds a maximum permissible exposure, the UE reduces the amount of radio frequency exposure associated with the human tissue.
