Abstract: Systems and methods are provided for uninterrupted multiple basic service set identifiers (MBSSIDs). In various embodiments, an MBSSID virtual access point (VAP) can be generated to facilitate an uninterrupted MBSSID. An access point (AP) can determine characteristics, or network properties, of VAPs associated with the AP. The AP can generate an MBSSID VAP based on the characteristics of the VAPs. An MBSSID beacon can be generated using the MBSSID VAP as a transmitted VAP (TX VAP) of the MBSSID beacon. The MBSSID VAP serves as a TX-VAP that is not subject to changes and does not need to be interrupted to have changes made to it. As the MBSSID VAP serves as a TX VAP that is not subject to changes or interruptions, the MBSSID based on the MBSSID VAP does not need to be interrupted for changes to be made to other VAPs associated with the MBSSID.

Abstract: Systems and methods are provided for transmitting buffer state report poll (BSRP) triggers from a WLAN device with a BSRP frequency that is based on an amount of pending data at the UL buffer of each station associated to the WLAN device. The BSRP frequency can further be based on a priority of the pending data at the UL buffer. The amount of pending data at the UL buffer can be compared to a threshold, the value of which can depend on the priority of the pending data, and the BSRP frequency can be based on the comparison.

Abstract: Systems and techniques are described that are directed to intelligent scheduling of Wi-Fi services for applications, including enhanced dynamic prioritization. A device, such as an access point (AP), can receive data packets from multiple connected devices to dynamically identify an application flow for each data packet, and dynamically identify a user associated with the application flow for each data packet. The AP can generate prioritized candidate lists for selected data packets in queues corresponding to an access category (AC). In response to determining that the identified user associated with the application flow corresponds with a critical user, the AP can select data packets for the prioritized candidate lists based at least in part on priority policies for each of a plurality of applications and based at least in part on dynamic prioritization of applications for each of a plurality of applications; and schedule data packets from the prioritized candidate lists.

Abstract: Systems and methods are provided for ensuring client device connectivity in a deployment pursuant to regulatory updates impacting channel usage or availability. An access point (AP) or AP controller may obtain a client-supported channel list, and detect existence of a regulatory update impacting channel usage in the network device. An AP-supported channel list is compared to the client-supported channel list, and a determination is made regarding which client devices associated to an AP do not support channel usage changes resulting from the regulatory update. Distribution of channels of the AP-supported channel list is controlled among one or more radios of APs in a deployment based on AP density of the deployment, and the determination regarding which client devices do not support the channel usage changes.

Abstract: Systems and methods are provided for adaptively enabling and disabling spatial reuse and adapting BSS color assignments based on various factors associated with a wireless network. A first AP in a wireless network can identify a second AP in a wireless network. The first AP and the second AP may be using the same wireless channel in the wireless network. The first AP can determine a signal strength, such as a received signal strength indicator (RSSI), associated with the second AP. The first AP can adapt its spatial reuse and BSS color assignment according to the signal strength and a signal strength threshold. By adaptively enabling and disabling spatial reuse and adapting BSS color assignments, the disclosed systems and methods provide for improved reuse of wireless mediums while avoiding collisions.

Abstract: Systems and methods are provided for multiple basic service set identifier (MBSSID) beaconing (from an access point (AP) standpoint) and MBSSID/virtual AP (VAP) scanning (from a client device perspective). To facilitate easier discovery of mesh APs/VAPs, BSSIDs associated with mesh VAPs can be advertised more frequently, e.g., being broadcast as a transmitted or non-transmitted BSSID in each MBSSID beacon. Additionally, information regarding mesh VAPs, such as mesh capability information, can be provided via intermediate discovery beacons or frames such that out-of-band scanning mechanisms can discover mesh VAPs faster. Additionally still, the existence of mesh VAPs can be advertised in a dedicated field of an MBSSID beacon.

Abstract: Systems and methods are provided for network scanning. For example, the systems and methods can address AP scanning in the WiFi-6 context, where AP scanning frequency and the number of 6 GHz channels can be reduced. Additionally, the timing of AP scanning (on 2.4/5/6 GHz channels) can be adjusted to wait until STA's buffered frames are sent to AP and/or while a STA is asleep due to time TWT.

Abstract: Systems and methods are provided for synchronizing uplink (UL) and downlink (DL) traffic. In particular, frames associated with Quality of Service (QoS}-sensitive traffic flows to be transmitted in a first direction are prioritized commensurate with frames to be transmitted in a second direction, different/opposite to that of the first direction. For example, UL traffic flows can be prioritized based on DL traffic flows, where the traffic flows belong to the same application flow, and vice versa, where DL traffic flows can be prioritized based on UL traffic flows for the same application flow. In this way, end-to-end QoS can be achieved.
