    Abstract: Implementations of the present disclosure relate to selecting a transmitting virtual access point (VAP) for a MBSSID set. A method comprises selecting a VAP from a set of VAPs as a transmitting VAP based on context information about the set of VAPs, at least one of the set of VAPs other than the transmitting VAP being determined as at least one non-transmitting VAP The method also comprises generating a beacon frame for the set of VAPs by including an identifier of the transmitting VAP in a header part of the beacon frame and including at least one identifier of the at least one non-transmitting VAP in a payload part of the beacon frame. A generated beacon frame is broadcasted. In this way, a transmitting VAP of a set of VAPs is no longer determined by default, but can be selected for different cases.

    Abstract: A method for protecting 802.11 ax networks includes receiving, by an access point, a plurality of Single User (SU) Quality of Service (QOS) NULL frames from a station, tracking, by the access point as the plurality of SU QOS NULL frames are received, a variable in one or more of the plurality of SU QOS NULL frames, determining, by the access point and based on tracking the variable, the station is suspicious, sending, by the access point and in response to determining the station is suspicious, a request to check a status of the variable, determining, by the access point and based on a response to the request, the station is under attack, and flagging, by the access point, the station as under an attack.

    Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for increasing the reliability of voice traffic and Transmission Control Protocol (TCP) Acknowledgement (ACK) messaging. The result is improved quality of voice calls, and enhanced network capacity. When the length of a data section of a packet suggests that subsequent packets are associated with voice traffic or TCP ACKs, such packets are not transmitted when another transmission(s) is occurring under spatial reuse. When a determination is made that the length of a data section of the packet suggests non-voice traffic or TCP ACKs, they can be transmitted simultaneously with other transmissions occurring under spatial reuse.

    Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for reducing channel access latency via selective application of SR for latency-sensitive and high-priority traffic. If a radio frequency (RF) signal is detected on a channel used by an access point (AP) or a client device, a determination can be made as to whether the energy of the RF signal relative to SR energy level thresholds permits transmission on that channel used simultaneously by another, e.g., neighboring AP. If so, frames can be transmitted so long as the other neighboring AP is associated with a different basic service set (BSS) color than that of the AP, and so long as the frames to be transmitted belong to a high-priority/low-latency traffic access category.
