Abstract: System and techniques for a multi-class Long Range Lower Power (LRLP) access point (AP) multifactor intelligent agent control are described herein. A station (STA) association at the AP is received. Here, the association includes Class Identifier (ID) information. The Class ID information encompasses a set of communication parameters. A schedule of LRLP and non-LRLP STAs with associations at the AP is maintained. A transceiver chain is modified based on the schedule and the set of communication parameters to complete a communication with the STA.

Abstract: Densely populated wireless local area networks (WLANs) can encounter issues with processing multiple user (MU) uplink (UL) transmissions sent from many stations (STAs) simultaneously. The access points (AP) or master stations in these densely populated WLANs must manage the UL MU transmissions. To accomplish the management of the UL MU transmissions, a system for dynamically setting UL MU parameters is provided that can modify or set one or more parameters that govern how each STA is to transmit data to the AP. The parameters may be sent to one or more of the STAs in one or more transmissions and may direct how the STAs are to transmit data for at least some portion of time.

Abstract: The application relates to a method and apparatus used in Wireless Local Area Networks (WLANs). The apparatus includes: a Radio Frequency (RF) interface; and processor circuitry coupled with the RF interface and configured to: determine Buffered Unit (BU) information, which indicates presence or absence of BUs for a set of non-Access Point (AP) Multi-link Devices (MLDs) on an AP MLD; encapsulate the BU information for the set of non-AP MLDs in a Multilink (ML) Traffic Indication Map (TIM) information element; and provide the ML TIM information element to the RF interface for broadcasting, wherein the ML TIM information element comprises a series of TIM segments and each TIM segment contains the BU information, which indicates the presence or absence of BUs for a subset of non-AP MLDs on a corresponding AP within the AP MLD.

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.
