Method and system for Wi-Fi sensing

A computing device, comprising:

• a processor;
• and
• a non-transitory computer-readable memory storing instructions that when executed by the processor cause an initiating wireless station (STA) to perform actions comprising:
• sending, to a plurality of responder STAs, a sensing request for detecting objects and human activities, the sensing request comprising a sensing announcement frame indicating:
• identifiers of the plurality of responder STAs;
• and
• resource unit assignments for receiving acknowledgements from the plurality of responder STAs;
• receiving, from the plurality of responder STAs, one or more responses based on the sensing request;
• and
• receiving, from the plurality of responder STAs, the acknowledgements indicating a willingness to participate in the sensing procedure.

• identifiers of the plurality of responder STAs;
• and
• an uplink (UL) sensing;
• receiving, from the plurality of responder STAs, one or more responses based on the sensing request, including receiving one or more sensing frames based in part on the sensing announcement frame and the SFR TF;
• and
• sending, to the plurality of responder STAs, a sensing feedback request (SFR) trigger frame (TF).
