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: 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.

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.
