  • Patent number: 11336487
    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.

  • Publication number: 20220132528
    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.

  • Publication number: 20220116815
    Abstract: Systems and methods for providing enhanced Quality of Service (QoS) network transmissions can be based on an application sub-class or a user class. Systems and methods can include inspecting the information packet having a network level QoS field having a first network level QoS portion and a second network level QoS portion, determining an application sub-class or user class associated with the information packet, tagging the first network level QoS portion of the information packet according to a first network level QoS value, tagging the second network level QoS portion of the information packet according to a traffic priority indication and to a determined application sub-class or user class, and queuing the information packet for transmission from a network element based on the tagged first network level QoS portion and the second network level QoS portion.

  • Publication number: 20220116842
    Abstract: Systems and methods for dynamic client segregation in 802.11ax networks includes determining, for each access point of a plurality of access points in a network, a ratio comprising a number of fully uplink multi-user capable client devices to a total number of client devices connected to the access point; and steering, based on at least the ratio, client devices of the network to particular access points of the plurality of access points.

  • Publication number: 20220110052
    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.

  • Patent number: 11277794
    Abstract: Systems and methods for power save aware resource unit allocation include sending, by an access point to a station, a beacon indicating that the station has data buffered at the access point, wherein the station is in a power-save mode, sending, by the access point after sending the beacon, an Orthogonal Frequency Division Multiple Access (OFDMA) trigger to the station, wherein the OFDMA trigger causes the station in the power-save mode to send PS-POLL using OFDMA, receiving, by the access point and from the station, a PS-POLL frame using OFDMA.

  • Publication number: 20210409961
    Abstract: Systems and methods are provided for optimizing the channel switching process in an access point. Periodic background scanning of a current channel on which a radio is operating to determine channel utilization can be used to generate a ranked channel list from which to select an alternative channel to which the radio can migrate, for example, in the event of a radar signal(s) being detected on its current channel. To maintain connectivity for clients, the clients may be temporarily transitioned to a non-DFS channel while an isolated/dedicated radio chain is used to perform the requisite Channel Availability Check (CAC) assessment on a DFS channel if the radio, based on the ranked channel list, selects a DFS channel as the alternative channel.

  • Publication number: 20210409957
    Abstract: Systems and methods for partitioning radio spectrum in an AP to support a mixed client environment while maintaining efficient 802.11ax transmissions is provided. Clients in a zone may be categorized into 802.11ax and legacy clients, and those clients may further be categorized into a majority population and a minority population. Assignment of the minority and majority populations can be effectuated by considering the number of available channels to be assigned to each population of client devices, as well as steering load/cost and a client device's ability to be steered to another channel. Moreover, assignment of the minority and majority populations can take into account maintaining a particular client-channel density.
