Abstract: Systems and methods are provided for opportunistic spatial reuse. In various embodiments, the disclosed systems and methods provide for mechanisms for enabling and disabling spatial reuse in a wireless network as appropriate based on the deployment of the wireless network. In some embodiments, spatial reuse can be enabled and disabled based on various factors, such as channel utilization. In some embodiments, spatial reuse can be enabled and disabled as appropriate for various types of traffic in a wireless network. For example, spatial reuse can be enabled and disabled for downlink traffic (e.g., traffic from an access point to a client device), for uplink traffic (e.g., traffic from a client device to an access point), for multicast or broadcast traffic (e.g., traffic distributed to multiple recipients), or for certain modes of transmission (e.g., single user beamformed transmission, Dual Carrier Modulated transmission).

Abstract: Systems and methods are configured to receive a first request to schedule a Time To Wake (TWT) service period (SP) for a first station. The first request can be based on individual TWT protocol. That the TWT SP satisfies a threshold level of similarity with an existing TWT SP maintained for a group of at least one station scheduled to communicate over the existing TWT SP can be determined. The group can include a second station. The first station can be assigned to the group. A first packet can be transmitted to the first station and a second packet can be transmitted to the second station over the existing TWT SP.

Abstract: An access point (AP) in a deployment may be attacked by a rogue AP. The rogue AP may transmit fake beacons that include a fake/incorrect basic service set (BSS) color that does not match the BSS color assigned to/used by the AP under attack. Due to this BSS color mismatch, stations associated to the AP under attack may switch to the fake/incorrect BSS color, and communications between the AP under attack and the stations may be disrupted, and can eventually lead to service denial. Systems and methods are provided for leveraging the BSS color feature to identify when a rogue AP is attacking another AP. Upon detecting an attack, the BSS color feature may be disabled to mitigate the level of service disruption to the AP under attack and the stations associated to that AP.

Abstract: A system and method for optimizing a channel sounding procedure of a multi-link device (MLD) is disclosed. The improved channel sounding procedure disclosed herein involves an MLD requesting channel sounding information from a group of receivers on a first channel representing a first physical frequency, but receiving channel sounding information from a subgroup of the receivers on one or more other channels representing different physical frequencies. In this manner, the channel sounding procedure on a specific link of an MLD is optimized by offloading some of the sounding process to a different radio link that is also operational for the MLD as part of the same association context.

Abstract: Systems and methods are provided for generating an MBSSID virtual access point (VAP) 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: Examples of techniques for handling unsolicited probe responses are disclosed. In an example, occurrence of an attack on an access point (AP) in an enterprise Wireless Local Area Network (WLAN) is detected based on an unsolicited probe response and Robust Security Network Information Element (RSN IE). Responsive to detecting the attack, unsolicited probe responses at the AP is disabled. Further, Fast initial Link Setup (FILS) discovery at the AP is enabled.

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: The full efficiency gains of the Target Wake Time (TWT) mechanism specified in the 802.11ax standard may not be realized when stations associated to an access point (AP) are spread across multiple Base Station Service Identifiers (BSSIDs). In such a scenario, TWT as conventionally utilized/specified in the 802.11ax standard, cannot properly coordinate sleep/wake schedules for stations due to associating to different BSSIDs. Accordingly, various embodiments are directed to grouping stations associated to multiple BSSIDs of an AP to allow for the synchronization (or staggering) of TWT, and facilitate multi-user transmissions, both in the uplink and downlink directions.

Abstract: The present disclosure describes examples of the mechanism of a Supplemental Beacon. The Supplemental Beacon may be used as an additional beacon to an original main beacon in a Wi-Fi system. The Supplemental Beacon may be transmitted in a Short Interframe Space (SIFS) interval preceding the transmittance of the main beacon. Establishing set times of the Supplemental Beacon transmittance before the main beacon may allow client devices to wake up at consistent time intervals to receive data, and allow client devices to only remain awake for a short duration between the Supplemental Beacon transmittance and the main beacon transmittance before going back to sleep. The support of a Supplemental Beacon to the main beacon at fixed times of short duration before the main beacon that may allow the conservation of power of client devices and network devices in the Wi-Fi system, and increase productivity in the transmission of data.

Abstract: A dynamic BSS color feature for co-hosted virtual access points is described. An example of a storage medium includes instructions to operations including enabling, by an access point, a dynamic basic service set (BSS) color feature for operation with multiple virtual access points (VAPs) hosted by the access point; switching a parameter of the access point to indicate that no co-hosted BSS is present; assigning a different BSS color to each of the VAPs; performing access point operations, including utilizing the assigned BSS colors for transmissions relating to any of the VAPs; and disabling the dynamic BSS color feature upon occurrence of one or more conditions.
