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: 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: 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: 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: 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 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.
