Abstract: A Traffic Classification (TCLAS) element enhancement for Low Latency, Low Loss, Scalable Throughout (L4S) flow classification may be provided. First, a client device may determine that a flow is an L4S flow. Next, the client device may communicate that the flow is L4S using an enhanced TCLAS element. Then an Access Point (AP) may use the enhanced TCLAS element to schedule the flow.

Abstract: Signaling preference order of links and maximum allowed links for multi-link operation may be provided. First, an Access Point (AP) Multilink Device (MLD) may receive an indication that a non-AP MLD supports preference ordering for requested links (that are indicated in the Per-STA profile sub-elements). Then the AP MLD may indicate that it supports preference ordering for requested links (that are indicated in the Per-STA profile sub-elements). Next, the AP MLD may receive from the non-AP MLD, a desired preference ordering for the requested link. The AP MLD may then consider the desired preference ordering for requested links.

Abstract: Low Latency, Low Loss, Scalable Throughput (L4S) support and queuing and, specifically, L4S proxy support for non-L4S-compatible devices and L4S queuing for Access Points (APs) may be provided. Providing L4S support can include determining a flow for a L4S capable Station (STA) is L4S enabled. In response to determining the flow is L4S enabled, a shallow queuing mechanism is implemented for queuing traffic by replacing one or more alternate queues with one or more L4S queues, the shallow queuing mechanism comprising one or more classic queues and the one or more L4S queues. L4S traffic of the flow is queued in at least one of the one or more L4S queues.

Abstract: A multi-link procedure to identify link disablement in Basic Service Set (BSS) transition management frames may be provided. First, a Basic Service Set (BSS) Transition Management (BTM) request may be created. The BTM request may indicate a link disablement that will happen in the future. Then the BTM request may be sent.

Abstract: Low Latency, Low Loss, Scalable Throughput (L4S) queuing and marking and, specifically, L4S parameters for congestion marking and a new congestion flag for predicted congestion events may be provided. Providing L4S marking can comprise determining, in layer 2, a packet is experiencing congestion. A L4S marking request is sent to layer 3 to request congestion marking of the packet. The packet is marked in layer 3 for congestion experienced A L4S marking response comprising the marked packet is then sent to layer 2.

Abstract: Irregular absence signaling may be provided. An Access Point (AP) may receive an irregular absence report from a station. The AP may parse the irregular absence report to determine upcoming absence periods of the station for non-Peer-to-Peer (P2P) traffic. The AP may schedule Transmit Opportunity's (TxOPs) of the non-P2P traffic to the station based on the determined upcoming absence periods.
