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 Quality-of-Service (QoS) Management AP is configured to support QoS Management features and to perform a QoS Management Protocol. The AP decodes an Enhanced Add Traffic Stream (E-ADDTS) Request QoS Action Frame (E-ADDTS Req) received from a station (STA) to initiate QoS setup for a traffic stream. The STA may be a QoS Management STA configured to support the QoS Management features and perform the QoS Management protocol. The AP may encode, for transmission to the STA in response to the E-ADDTS Req, an E-ADDTS Response QoS Action Frame (E-ADDTS Resp) which includes a status code to indicate whether the QoS setup has been accepted. When the QoS setup is accepted, the E-ADDTS Resp includes a QoS setup ID within a QoS setup ID field in the E-ADDTS Resp that uniquely identifies the QoS setup for the traffic stream.

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.

摘要： An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.

摘要： This disclosure describes systems, methods, and devices related to link switch parameters. A device may generate a frame to be sent to a second device on a first link. The device may generate announcement information associated with the frame to notify other STAs about a data transmission of the frame. The device may cause to send on the first link the frame to the second device. The device may cause to send the announcement information with the data transmission of the frame.

摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable for multi-band operation in a plurality of frequency bands, each frequency band comprising one or more channels. The AP may select a subset of the frequency bands for which the AP is to request per-band channel availability information from the STA. The AP may transmit a Trigger Frame (TF) for a multi-band bandwidth query report polling (MB-BQRP) to request the per-band channel availability information. The AP may receive an uplink frame that includes a multi-band bandwidth query report (MB-BQR) that indicates the per-band channel availability information. The AP may determine, based on the MB-BQR, for an uplink transmission by the STA: one or more frequency bands of the subset of frequency bands, and one or more corresponding channels.

摘要： For example, an Access Point (AP) may be configured to identify a Trigger-Based (TB) sensing measurement exchange of a Wireless Local Area Network (WLAN) sensing procedure to be initiated by the AP. For example, the AP may be configured to determine that a non-AP Multi-Link Device (MLD) at an Enhanced Multi-Link Single Radio (EMLSR) operation mode is to participate as a sensing responder of the TB sensing measurement exchange. For example, the AP may be configured to transmit an Initial Control Frame (ICF) addressed to the non-AP MLD prior to initiating the TB sensing measurement exchange, for example, based on the determination that the non-AP MLD at the EMLSR operation mode is to participate as a sensing responder of the TB sensing measurement exchange.

摘要： A multi-link access point (AP) device is configured for multi-link operation to communicate with a plurality of non-AP stations (STAs) over a plurality of corresponding links. A multi-link policy element is encoded for transmission to the non-AP STAs to signal a multi-link policy. The multi-link policy element comprises a common policy sub-element and a plurality of link-specific policy sub-elements. The common policy sub-element is applicable to all links. Each of the link-specific policy sub-elements is applicable to a single link. The link-specific policy sub-elements comprise at least a first link-specific policy sub-element applicable to a first link and a second link-specific policy sub-element applicable to a second link. The common policy sub-element defines a link policy for all links that have been set up between the multi-link AP device and the non-AP STAs. Each link-specific policy element defines a link policy specific to an associated link.
