摘要： A station (STA) (STA-1) configured for wireless local area network (WLAN) sensing establishes a sensing measurement agreement with another STA STA-2 to perform a sensing measurement setup with the other STA. The sensing measurement setup may comprise an exchange of sensing measurement request and response frames to establish sensing measurement parameters associated with a sensing measurement instance. The Sensing Measurement Setup Request frame and the Sensing Measurement Setup Response frame may be configurable to include a variable length Measurement Sensing Parameters field and a sensing sub-elements field to include one or more of the sensing measurement parameters. The sensing measurement parameters may, for example, comprise one or more of a bandwidth (BW) field, one or more fields for a number of space-time streams (STS) and a number of long-training field (LTF) and LTF repetitions that the STA is capable of transmitting and receiving, and an immediate or delayed feedback reporting field.

摘要： A station (STA), when operating as a responding STA (RSTA) for time-synchronization of a plurality of initiating STAs (ISTAs) in a time-synchronized network (TSN), may determine, during a negotiation phase, whether each of the ISTAs that intend to participate in one or more measurement phases are requesting to be polled or are requesting not to be polled. For the ISTAs that are requesting to be polled, the RSTA may perform a polling phase prior to performing each of the one or more measurement phases. For the ISTAs that are requesting not to be polled, the RSTA may refrain from performing a polling phase prior to performing each of the one or more measurement phases. The RSTA can directly trigger the measurement phase for ISTAs that are requesting not to be polled. By grouping ISTAs into polling and non-polling groups, efficiency improvements are achieved.

摘要： 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.
