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: Techniques for peer-to-peer (P2P) transmission in a multi-user (MU) multiple-input-multiple-output (MIMO) environment. A first wireless station (STA), including a plurality of radio antennas, identifies channel state information (CSI) relating to a connection between the first STA and a wireless access point (AP). The first STA determines connection information relating to a MU MIMO P2P connection between the first STA and a second STA. The first STA generates a plurality of values relating to precoding for the plurality of radio antennas, based on the CSI and the connection information. The first STA and the second STA exchange data over the P2P connection, using the plurality of values relating to precoding.

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: Application-based Transmission Opportunity (TXOP) sharing may be provided. First, a sharing AP may receive a request to share TXOPs with a requesting AP. The request may include information associated with an application executing on a client serviced by the requesting AP. Next, a TXOP duration for the requesting AP may be reserved based on the information associated with the application such that, in response to winning contention on the medium, the sharing AP may share a TXOP with the requesting AP for the TXOP duration.

Abstract: Techniques are disclosed for determining one or more radio resource management (RRM) input parameters. The one or more RRM input parameters are determined based on a line of sight (LOS) estimate between two wireless stations (STAs). A plurality of RRM values are generated based on the one or more RRM input parameters. A wireless connection is established between a first wireless access point (AP) and a first STA using the RRM values.

Abstract: A network system comprises a plurality of access points (APs) and a distributed cache. The distributed cache is formed using memory in the plurality of APs. The plurality of APs are configured to measure telemetry data and store the telemetry data in the distributed cache. One of the plurality of APs is assigned as a controller AP configured to assign, based on the telemetry data stored in the distributed cache, multiple APs of the plurality of APs to different roles to analyze the plurality of APs and update resource configurations of the plurality of APs.

Abstract: Aspects described herein include an exclusionary approach for basic service set (BSS) color selection and assignment in a network. A network controller for a network selects a radio associated with an access point (AP) under management of the network controller and determines a potential set of BSS colors for the radio. The network controller then removes/excludes a set of BSS colors that impacts the radio from the potential set of BSS colors and updates or assigns a BSS color for the selected radio using the potential set of BSS colors, minimizing the chances that the assigned BSS color will cause an overlapping BSS color condition in the network.

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: Techniques for assigning APs to wireless network controllers are described. One or more RF constellations for a plurality of APs in a wireless network are generated. The RF constellations are organized based on estimated RF distances among the plurality of APs. The plurality of APs are clustered into a plurality of groups of one or more APs, based on the RF constellations and the estimated RF distances. Each group, of the plurality of groups, is assigned to a wireless network controller.

Abstract: An algorithm for determining redundant radios in APs is disclosed. The algorithm first performs a coverage peak flattening algorithm to predict an impact to the total coverage area if a radio in a selected AP does not transmit signals in a frequency band. If the impact to the total coverage area is acceptable, the algorithm then performs a multi-point check algorithm to determine whether the radio in the selected AP is redundant in the frequency band. After determining that the radio in the selected AP is redundant in the frequency band, the algorithm transforms the redundant radio into various services based on the network deployment and user preference.
