1. A method for Wi-Fi sensing carried out by a sensing responder including a transmitting antenna, a receiving antenna, and at least one processor configured to execute instructions, the method comprising:
receiving, via the receiving antenna, a sensing transmission announcement;
receiving, via the receiving antenna and subsequent to receiving the sensing transmission announcement, a plurality of sensing transmissions from a sensing transmitter;
obtaining, by the at least one processor of the sensing responder, a plurality of channel representation information based on the plurality of sensing transmissions;
identifying, by the at least one processor of the sensing responder, that differences between the plurality of channel representation information and a sensing imprint exceed a threshold associated with motion in a sensing space, wherein the sensing imprint is representative of a previously measured CSI and was previously transmitted for sensing measurement processing and wherein the plurality of channel representation information have not been transmitted by the sensing responder;
counting a number of the differences that exceed the threshold; and
transmitting, via the transmitting antenna of the sensing responder responsive to identifying that the number of the differences that exceed the threshold is greater than or equal to a delta count value, a sensing measurement report to a sensing initiator.
