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.

Abstract: Management of radio resources of a wireless network according to a Flexible Radio Assignment (FRA) mode may be provided. For each Access Point (AP) of the wireless network: a type of AP may be identified including determining whether each AP has Multi-Link (ML) capability, and when the FRA mode is for performance, a bias may be applied to each ML capable AP to reduce a likelihood of a radio of each ML capable AP being identified as a redundant radio. For each Client Device (CD) of the wireless network, an identification of whether each CD has ML capability may be made, and a radio configuration of at least one ML capable AP may be tailored to support one or more ML capable CDs.

Abstract: Techniques for a machine learning event-driven radio resource management (ED-RRM) module which provides analysis of interference events in a network system are described. The network system reacts to the detection of interference in a network system and uses multiple input parameters to determine a type of device creating the interference, a predicted duration of the interference, and an ED-RRM decision on whether to activate the radio resource management (RRM) processes to alter the network transmission or block the RRM processes to conserve system resources for the network system.

Abstract: Coordinated Frequency Division Multiplexing (FDM) Transmission Opportunity (TXOP) sharing may be provided by determining that at least two Access Points (APs) of a wireless network support coordinated FDM TXOP sharing. In response to the determination that the at least two APs support coordinated FDM TXOP sharing, at least one of: a first bias is applied to a channel assignment algorithm to promote an assignment of overlapping channels of the at least two APs, and a second bias is applied to the channel assignment algorithm to promote an assignment of adjacent channels of the at least two APs. Next, channels are assigned to the at least two APs based on an output of the channel assignment algorithm.

Abstract: Optimization of radio communications of a wireless network of a local site may be provided. A probe frame or an association frame may be received from a Client Device (CD) operating in the local site that identifies at least one operating class and Multi-Link (ML) capability information of the CD. Channel information of at least one Access Point (AP) having ML capability in the local site may be embedded in a probe response frame or in an association response frame based on the at least one operating class and the ML capability information of the CD. The probe response frame or the association response frame that includes the channel information of the at least one AP having ML capability in the local site may be transmitted, as unicast, to the CD.

Abstract: Mitigation of active link alternation by multi-link devices (MLDs) may be provided. First, at least first and second links may be established between an Access Point (AP) MLD and an associated MLD client. The first link may be active, while the second link may be inactive. A set of traffic load data associated with the links may be collected before and after transmission of a Basic Service Set (BSS) load report to the MLD client. The report may include a traffic load on the second link prior to transmission, where the second link is less loaded than the first link. Based on the collected traffic load data, an active link alternation from the first to the second link by the MLD client responsive to receiving the report may be detected. One or more methods for BSS load report management may then be applied to mitigate future active link alternation.

Abstract: Techniques for dynamic RF site configuration are provided. Historical association data is collected from a plurality of access points in a physical environment, and a machine learning model is trained to predict future association events, based on the historical association data. Current association data is then collected from the plurality of access points, and at least one predicted association event is generated by processing the current association data using the trained machine learning model. The plurality of access points is allocated to a plurality of radio frequency (RF) sites based on the at least one predicted association event. Finally, at least one of the plurality of RF sites is configured based on the predicted association event.
