Abstract: An access point in a wireless network communicates wirelessly with one or more client devices over a channel that includes a plurality of subchannels. Radar is detected on a first subchannel of the plurality of subchannels. It is determined to puncture the first subchannel, based on the detecting the radar on the first subchannel and based on one or more puncturing factors. The first subchannel is punctured, the puncturing comprising muting one or more subcarriers on the first subchannel.

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: 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.

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 are provided for optimizing performance of a multi-link device (MLD). In one embodiment, a controller receives information about a filter response for a first multi-link device (MLD, determines, based on the information about the filter response, a filtering transitional region of the first MLD indicating a range of frequencies where there is energy leakage due to the first MLD device operating in a simultaneous transmission and reception (STR) mode, determines cost metrics for a plurality of channels by identifying a STR and non-STR (NSTR) ratio for each of the plurality of channels, and assigns, based on the filtering transitional region and the cost metrics, a first radio of an access point (AP) to one of the plurality of channels to enable the first MLD to operate in the STR mode when communicating with the first radio.

Abstract: Spurious beamforming in high density environments can be reduced via transmitting a first signal from a first Access Point (AP) to a first endpoint associated with the first AP via a first beamforming arrangement; in response to identifying that the first beamforming arrangement is pollutive to a second endpoint associated with a second AP: deprecating the first beamforming arrangement; and transmitting a second signal from the first AP to the first endpoint via a second beamforming arrangement, different from the first beamforming arrangement.

Abstract: A method is provided in which an AP of a MLD AP device may decide to include all out-of-link BSS parameters updates in a beacon frame (beacon). A flag is included in the beacon frame to indicate that all updates are included in the beacon frame and thus the client device that receives the beacon frame should not send probe request frames (probe requests) to obtain these updates. Thus, a non-AP MLD that receives a beacon frame with the above indication and that has all critical BSS parameters corresponding to the Change Sequence Number (CSN) that preceded the updates indicated by the AP, should not send probe requests to obtain the updated parameters. The number of bits to assign to the complete BSS Update Report Indication flag may vary depending on the number of updates to be reported.

Abstract: A method to operate a multi-link wireless device. The method includes establishing at least a first multi-link device interface and a second multi-link device interface, exposing, via a virtual data port, the first multi-link device interface and the second multi-link device interface at a data processing layer of the wireless device, selecting one of the first multi-link device interface and the second multi-link device interface, as a selected multi-link device interface, based on performance information associated with a first radio and a second radio associated, respectively, with the first multi-link device interface and the second multi-link device interface, and wirelessly transmitting a packet from the wireless device by routing the packet through the selected multi-link device interface.

Abstract: Automated activation of unsolicited probe responses may be provided. Probe traffic data may be received. Then, based on the probe traffic data, a plurality of probe traffic cost metrics may be determined. Each one of the plurality of probe traffic cost metrics may be respectively associated with a plurality of Unsolicited Probe Response (UPR) modes. An Access Point (AP) may then be operated in a one of the plurality of UPR modes that has a respective probe traffic cost metric that indicates a lowest probe traffic cost of the plurality of probe traffic cost metrics.
