Abstract: Network side beacon reports (NSBRs) may be generated based on probe signals received from one or more client devices (CDs) in a wireless network. Once enabled, an NSBR mode is configured to generate NSBRs remotely from a CD. When in the NSBR mode, an NSBR may be generated based on compiled probe signal parameters associated with one or more probe signals received from the CD.

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: In an example embodiment, a neighbor radio/access point (AP) list is obtained. The neighbor AP list is optimized for a client that is associated with a current access point. The list may be optimized based on any one or combination of techniques, including but not limited to roaming patterns of previous clients that were associated with the current access point, radio frequency metrics, bandwidth requirements for the client, and/or any other suitable criteria. In particular embodiments, requests from the client to associate with an access point that is not on the optimized neighbor AP list may be denied.

Abstract: Dynamic configuration of Overlapping Basic Set Service Preamble Detect (OBSS/PD) parameters for an Access Point (AP) may be provided. First, a plurality of stations within a Spatial Reuse (SR) range of the AP may be determined. Next, Signal to Interference plus Noise Ratio (SINR) calculations associated with the plurality of stations may be performed to determine an SINR impact on the plurality of stations if the AP performs an SR transmission given OBSS/PD parameters currently configured for the AP. Then, based on the SINR calculations, the OBSS/PD parameters for the AP may be dynamically adjusted.

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: Embodiments herein describe using a dual assess point (AP) to establish two access points that both are established by two individual radios (e.g., two 5 GHz radios). Generally, APs experience highly degraded performance when two co-located radios operate within the same band. In one embodiment, AP devices can deploy same band radios using a macro-micro cell approach. Thus, the AP may intelligently hand off client devices between the micro and macro cell in a way that optimizes the system for overall throughput and low packet latency while creating minimal oscillation of clients between cells. The embodiments in this disclosure disclose techniques that direct clients in a manner that optimizes these factors.

Abstract: Channel availability check optimization may be provided. A plurality of Pulse Repetition Intervals (PRIs) may be determined for a respective plurality of bursts on a respective plurality of frequencies. A list of at least a portion of the plurality of frequencies may be generated. The list may include a plurality of bias factors respectively indicating a probability that each of the respective plurality of bursts was a radar burst based on the respective plurality of PRIs. An Access Point (AP) may perform a plurality of preemptive Channel Availability Checks (CACs) on each of the respective plurality of frequencies on the list in order of highest probability to lowest probability based on the plurality of bias factors.

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.
