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.

Abstract: Systems and methods are provided for using a short data frame sent at a particular rate that can be used to probe a channel on which an access point is operating. The rate can be increased/decreased depending on whether or not transmission of the short data frame was successful or not. In this way, the highest possible rate (which can be impacted by any or all of the following factors: number of spatial streams, modulation and coding scheme, channel bandwidth, guard interval) can be selected to transmit data on the channel. In other words, a transmission rate can be selected dynamically and on a per-packet basis for a spatial reuse data frame that would follow the short data frame based on whether transmission of the short data frame was successful.

Abstract: Examples described herein relate to a method for reconfiguring a beacon by an access point (AP) to minimize or avoid network outages experienced by client devices connected to the AP. The AP transmits a beacon comprising a basic service set identifier (BSSID) field and a Multiple BSSID (MBSSID) element. The MBSSID element corresponds to an MBSSID set comprising a transmitted BSSID associated with a transmitted virtual access point (VAP) and a non-transmitted BSSID associated with a non-transmitted VAP, where the BSSID field in the beacon is set to the transmitted BSSID. Further, the AP reconfigures the beacon to generate a reconfigured beacon upon determining that the transmitted VAP is non-functional. In particular, the BSSID field in the reconfigured beacon is set to the non-transmitted BSSID of the MBSSID set. Moreover, the AP transmits the reconfigured beacon to the client device.

Abstract: Systems and methods are provided for transmitting low latency traffic in next generation wireless local area networks. A new Media Access Control (MAC) layer frame can be transmitted by an AP to establish a reserved time period during which interference from/collisions with other stations transmitting non-high priority data is avoided. Stations with non-high priority data queued for transmission can defer accessing a channel on which to effectuate the transmission until the reserved time period expires.

Abstract: Systems and methods are provided for encryption enhancement for a multi-link operation. Various subsets of addresses (or all addresses) associated with the frame are set to a determined known value, allowing encryption of the mac protocol data unit (MPDU) at a controller without knowledge of which particular link the frames will be sent. The multi-link devices (MLDs) used in the above communication may conduct communications in compliance with the IEEE 802.11be standard.

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: 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: Systems and methods are provided by which all APs in a particular deployment can be used to assist in the out-of-band discovery of 6 GHz radios by client devices. That is, a series of iterative operations can be performed to: (I) determine the state of 6 GHz radios in a zone/deployment area; (II) identify what radios can be considered near-neighbors to non-6 GHz radios for purposes of advertising one or more of the 6 GHz radios; (Ill) rank neighboring 6 GHz radios for a given non-6 GHz radio based on certain radio metrics; and (IV) ultimately determine those 6 GHz radios that can be advertised by the given non-6 GHz radio.

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.

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.

Abstract: Dynamic configuration of multiple radios of an access point is described. An example of an access point includes a processor; a memory; hardware filters; and a first set of radio chains and antennas, the access point including a first radio mode for operation as a single radio on a first channel to service a first BSS and a second radio mode for operation as a first radio on the first channel and a second radio on a second channel to perform an additional service, wherein the access point is to provide dynamic configuration of the radios including, upon determining that operation of the first channel to service the first BSS is not compatible with a particular hardware filter of the first radio, migrating the first BSS from the first radio to the second radio to service on the second channel, and providing the additional service on the first channel.

Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.

Abstract: Examples of triggered single user (SU) transmissions are described. In an example, an access point (AP) may send a SU trigger frame to a client device for initiating a data transmission by the client device. The AP may detect whether the data transmission is initiated within the Short Interframe Spacing (SIFS) after the SU trigger frame is sent. Responsive to detecting that the data transmission is not initiated within the SIFS, the AP waits for the client device to initiate the data transmission within a predefined time interval after the SIFS. Responsive to detecting that the data transmission is not initiated within the predefined time interval, the AP repurposes the channel access after the predefined time interval is elapsed. Responsive to detecting that the data transmission is initiated within the predefined time interval, the AP repurposes channel access after one of an expiration of a maximum transmission opportunity (TXOP) duration and a completion of the data transmission, whichever is earlier.

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.
