Abstract

Methods, apparatus and systems for wireless sensing are described. In one example, a described system in a wireless data communication network comprises: a transmitter configured to transmit a time series of at least one wireless sounding signal (WSS) based on a standard wireless network protocol associated with the wireless data communication network, and a receiver. The wireless data communication network comprises a physical (PHY) layer, a medium access control (MAC) layer, and at least one higher layer. The receiver is configured to: receive the time series of at least one WSS (TSWSS) based on the standard wireless network protocol through a wireless channel of a venue, and perform a plurality of wireless sensing measurements based on the received TSWSS to obtain sensing measurement results based on the standard wireless network protocol. The PHY layer or the MAC layer of the receiver provides the sensing measurement results locally to the at least one higher layer of the receiver based on the standard wireless network protocol. The sensing measurement results are available to the at least one higher layer of the receiver for performing a sensing-based task based on the sensing measurement results.
