  • Publication number: 20230087820
    Abstract: For wireless local area network (WLAN) sensing, a non-access point (AP) station (STA) sends a Measurement Setup Query frame to an access point station (AP) to signal one or more preferred time windows of the STA indicating when the STA is available to perform WLAN sensing with the AP. The STA receives a Measurement Setup Request frame received from the AP in response to the Measurement Setup Query frame. The Measurement Setup Request frame may indicate a time-window that is either within one of the preferred time-windows of the STA or a new proposed time-window that is not within one of the preferred time-windows of the STA. The STA may send a Measurement Setup Response frame to the AP to indicate an acceptance when the indicated time-window is within one of the preferred time-windows. The STA may send the Measurement Setup Response frame to indicate a rejection when the indicated time-window is not acceptable to the STA for performing the WLAN sensing procedure.
