    Abstract: Embodiments herein describe techniques for dynamically negotiating an SLA between a roaming device and a VN in an identity federation. Instead of an IDP having to individually negotiate with a VN to decide on an SLA before a user device roams to the VN, the parties can dynamically negotiate the SLA after the user device has detected the VN (but before the device is permitted to connect or associate with the VN). In one embodiment, when a roaming user device comes within wireless range of a VN, the roaming device receives an advertisement from the VN that indicates the current SLA (or SLAs) offered by the VN. The roaming device can compare this offered SLA to a stored SLA in an identity profile the device received from the IDP to determine whether to accept the offer. In another embodiment, the SLA is instead negotiated between VN and the IDP.

    Abstract: Coordinated Frequency Division Multiple Access (C-FDMA) for the simultaneous transmission of a basic Physical Layer Protocol Data Unit (PPDU) may be provided. C-FDMA may include determining sub-channels of a channel for one or more Access Points (APs). The sub-channels may then be assigned to the one or more APs. Transmit Opportunities (TxOps) may be scheduled for the one or more APs on the sub-channels. It may then be determined that a basic PPDU and an enhanced PPDU will be simultaneously transmitted on adjacent sub-channels. In response to determining the basic PPDU and the enhanced PPDU will be simultaneously transmitted on adjacent sub-channels, one or more Resource Units (RUs) of a sub-channel the enhanced PPDU will be transmitted on may be selected to disable transmission in.

    Abstract: Access Point (AP) coordination and, specifically, Multi-AP Coordination (MAPC) for Non-Simultaneous Transmit and Receive (NSTR) cross-band Physical Layer Protocol Data Unit (PPDU) alignment may be provided. The coordination can include determining to communicate with a client using MAPC Multi-Link-Device (MLD) operation. A first AP operating on a first band with a first link to the client and a second AP operating on second band with a second link to the client may be determined to communicate with the client. The first AP and the second AP may be coordinated to send one or more PPDUs with synchronized end times. The first AP may be instructed to transmit to the client via the first link and the second AP may be instructed to transmit to the client via the second link according to the coordination.

    Abstract: A method includes determining whether a first access point of a plurality of access points and a second access point of the plurality of access points should communicate simultaneously over a shared channel in a first network and in response to determining that one of the plurality of access points won contention of a transmission opportunity for the shared channel, dividing the transmission opportunity into a plurality of time slots. The method also includes scheduling transmissions of the first and second access points into the plurality of time slots according to the determination whether the first and second access points should communicate simultaneously over the shared channel and communicating, to the second access point and over a wired network or a second network different from the first network, an indication of whether the second access point should communicate during a first time slot of the plurality of time slots.

    Abstract: Handoff assistance across multiple radio access technologies can be provided by identifying a first Qualitative Level of Service (QLoS) of a first network that a User Equipment (UE) is connected to for data transmission; identifying a second QLoS of a second network that the UE is not connected to for data transmission; and in response to determining that a difference between the first QLoS and the second QLoS satisfies a handoff threshold, requesting a first access point in the first network to initiate handoff of the UE to a second access point in the second network or recommending from the first access point to the UE to request such a handoff, wherein handoff disconnects the UE from the first network for data transmission and connects the UE to the second network for data transmission.

    Abstract: Dynamic policy mapping is provided via mapping, by an Access Point (AP), a plurality of applications to a set of privilege groups for Quality of Service (QoS) levels in a network; transmitting the mapping of the privilege groups to a client device; receiving packets from the client device including QoS markers; and in response to determining that the QoS markers received from the client device do not match the privilege groups for the packets, performing a corrective action on the client device, wherein the corrective action includes one or more of: disassociating the client device from the network; and retransmitting the set of privilege groups to the client device. In some embodiments, the privilege groups are transmitted before the client device is associated with the AP, enabling the client device to select what AP to associate with based on the privilege groups.
