Abstract: Techniques are provided herein to allow a wireless network access point (AP) to more fully use its bandwidth in order to leverage the different bandwidth capabilities of different types of wireless client devices that the AP serves. The AP generates control parameters for usage of a plurality of channels in a bandwidth during a downlink transmission interval. The control parameters comprise information indicating channel assignments that result in multiple downlink transmissions that at least partially overlap in time to different wireless client devices according to their respective bandwidth capabilities. The AP transmits the control parameters in a control frame in advance of the downlink transmission interval on each of the plurality of channels in the bandwidth.

Abstract: Sending Quality-of-Experience (QoE) information to clients for selecting an Access Point (AP) may be provided. Sending QoE information can include determining values for a plurality of QoE attributes. Based on the values for the plurality of QoE attributes, a QoE indicator is determined. The QoE indicator is sent to a client, wherein the client is operable to use the QoE indicator to select an Access Point (AP) to connect to.

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 ranging and placement on a floorplan may be provided. A host AP may range each neighbor AP of the host AP. One or more neighbor APs that failed ranging with the host AP may be categorized in a failed neighbor AP list. The host AP may re-range each of the one or more neighbor APs in the failed neighbor AP list with a modified ranging parameter. At least one neighbor AP of the one or more neighbor APs may be categorized in the failed neighbor AP list that succeeded in re-ranging with the host AP in an extended range neighbor AP list.

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: Time Sensitive Networking (TSN) Quality of Service (QoS) in overlapped administrative domains may be provided. A first Access Point (AP) may detect at least a second AP in a Co-Channel Interference (CCI) range. A micro-transaction auction between the first AP and at least the second AP may be established, and the first AP may provide compensation to second AP to acquire an agreement, from the second AP, to forgo transmitting during an upcoming service period. Next, the first AP may schedule transmissions for the service period and then transmit in the service period without interference from the second AP.

Abstract: Preemption in wireless may be provided. Access Category (AC) parameters may be received for a preemption AC within a plurality of ACs. The preemption AC parameters may comprise a Contention Window maximum (CWmax) comprising a first predetermined value and a preemption Arbitrary Interframe Space Number (AIFSN) of less than or equal to a second predetermined value. AC parameters for others of the plurality of ACs may be received wherein a non-preemption AIFSN associated with any of the others of the plurality of ACs is greater than a sum of the first predetermined value the second predetermined value. Preemption for traffic in the preemption AC may be allowed.

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: Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.
