Abstract: A non-Access Point Extremely High Throughput Station (non-AP EHT STA) initiates a Quality-of-Service (QoS) setup by sending a Stream Classification Service (SCS) Request frame to an associated access point (AP). The SCS request frame may be encoded to have a request type field set to “Add” and may contain an SCS Descriptor element having a traffic description field, a traffic classification field, and a Multi-Link Operation (MLO) field. The non-AP EHT STA may decode an SCS Response frame from the AP that indicate whether the QoS setup has been added. The non-AP EHT STA may then exchange a QoS traffic flow with the associated AP in accordance with the QoS setup when the QoS setup has been added. When the QoS traffic flow ends, the non-AP EHT STA may encode a second SCS Request frame for transmission to the AP with the request type field set to “Remove” to delete the QoS setup.

Abstract: This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.

Abstract: 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.

Abstract: 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.

Abstract: System and techniques for multi-phase wireless sounding are described herein. A first set of stations may be selected by an access point from a plurality of stations known to the access point. The access point may then transmit a first sounding request to members of the first set of stations. The access point may receive a sounding report in response to the first sounding request from members of the first set of stations. The access point may then select a second set of stations from the plurality of stations based on the sounding report. This second set of stations is a proper subset of the first set of stations. The access point may then transmit a second sounding request to the second set of stations.

Abstract: Embodiments of an access point (AP), station (STA) and method for uplink sounding are generally described herein. The AP may transmit an uplink (UL) sounding trigger frame (TF) that indicates a request to receive UL sounding elements from a group of one or more stations (STAs). The AP may receive UL sounding elements from the STAs in accordance with UL multi-user multiple-input multiple-output (MU-MIMO) reception. The AP may also receive, from at least a portion of the STAs, UL sounding feedback that includes one or more UL sounding transmission parameters used by the portion of the STAs for UL sounding element transmissions. The UL sounding TF may further indicate the portion of the STAs that are to transmit the UL sounding feedback.

Abstract: Embodiments of a controller device and method for channel contention in a wireless network are generally described herein. The controller device may determine if a collision would occur for expected signal transmissions of a group of virtual devices, which may include one or more virtual access points (VAPs) and/or virtual stations (VSTAs). The determination of the collision may be based on transmission times and/or back-off intervals of the virtual devices. The controller device may transmit collision control messages to indicate whether colliding virtual devices are to delay signal transmissions. The VAPs may be configured to communicate with the VSTAs as access point (AP) instantiations. The VAPs may be configured to use different service set identifiers (SSIDs) and/or media access control (MAC) addresses in such communication.
