摘要： An access point (AP) station (STA) (AP STA) that is part of an AP multi-link device (MLD) may be configured as a reporting AP may encode a BSS Transition Management (BTM) request frame for transmission to one or more associated non-AP stations (STAs). The BTM request frame may include a neighbor report element encoded to include information about one or more neighbor APs. The neighbor report element may indicate whether the one or more neighbor APs identified in the neighbor report element are part of an AP MLD and, when a neighbor AP is indicated to be part of an AP MLD whether the reporting AP is part of the indicated AP MLD. The AP STA may decode a reassociation frame from one of the non-AP STAs for transition from one of the AP STAs of the AP MLD to one of the neighbor APs.

摘要： Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.

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： 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 station (AP) configured for wireless local area network (WLAN) sensing may be configured to perform a sensing measurement setup with a non-AP station (non-AP STA). The sensing measurement setup may comprise an exchange of sensing measurement request and response frames to establish sensing measurement parameters for one or more sensing measurement instances including trigger-based and non-trigger based sensing measurement instances. The AP may perform sensing measurements with the non-AP STA by transmitting and/or receiving one or more null-data packets (NDPs) for a sensing measurement instance. The NDPs may be configured in accordance with the sensing measurement parameters. For performing a non-trigger based sensing measurement instance when the AP is operating a sensing responder and when reporting was indicated in a sensing measurement setup request frame received from the non-AP STA, the AP may encode a sensing measurement report for transmission to the non-AP STA.

摘要： This disclosure describes systems, methods, and devices related to responder-to-responder Wi-Fi sensing between station devices. A device may cause to send, during a trigger frame sounding phase of a responder-to-responder Wi-Fi sensing, a sensing responder-to-responder sounding trigger frame to the first station device and the second station device, the sensing responder-to-responder sounding trigger frame associated with causing the first station device to send a responder-to-responder null data packet (NDP) to the second station device; cause to send, during a reporting phase of the responder-to-responder Wi-Fi sensing, a sensing report trigger frame to the second station device; and identify, during the reporting phase, a sensing measurement report from the second station device based on the sensing report trigger frame, wherein the sensing measurement report is indicative of measurements of the responder-to-responder NDP.

摘要： An access point (AP) station (STA) (AP STA) may be configured to operate as a multi-AP controller in a multi-AP network. A multi-AP group formation message is encoded for transmission to other APs in the multi-AP network. The multi-AP group formation message is encoded to notify the APs of the formation of an extremely-high throughput (EHT) multi-AP group, to designate whether an AP is a member of an EHT multi-AP group, and whether an AP can take the role of a coordinator AP or coordinated AP within the EHT multi-AP group. For multi-AP joint processing, the AP STA is further configured to encode an AP trigger frame for transmission to the APs in the multi-AP network. The AP trigger frame is to trigger physical layer (PHY) and medium-access control layer (MAC) parameter synchronization. The AP trigger frame is to trigger transmission of aggregated MAC protocol data units (A-MPDUs) by the APs that include MAC parameters and PHY parameters.
