Abstract: Systems and techniques for mitigating adjacent channel interference (ACI) in concurrent transmissions that include a peer-to-peer (P2P) resource unit assignment are described. An example technique includes determining that a downlink transmission from an access point to a first client station is subject to an amount of ACI from a P2P transmission from a second client station to a third client station. A set of mitigation actions is determined to reduce the amount of ACI to the downlink transmission, based at least in part on the amount of ACI. The set of mitigation actions are performed.

Abstract: Techniques for improved peer-to-peer communication are provided. A set connectivity metrics among a set of wireless devices on a plurality of wireless channels in a wireless network is collected, and a wireless channel of the plurality of wireless channels is identified, based on the set of connectivity metrics, to use for peer-to-peer communication. A request is received, from a peer-to-peer device, for peer-to-peer communications, and the wireless channel is indicated to the peer-to-peer device, where the peer-to-peer device uses the first wireless channel for peer-to-peer communications in response to the indication.

Abstract: Network traffic interference detection and management may be provided. An infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP may be detected, and information associated with the infringement event may be added to an infringement list, wherein the information includes a MAC address associated with the infringing AP. A controller, may receive the infringement list and notify the infringement event to the infringing AP. The infringing AP may determine whether a transmission associated with the infringement event is low latency and high priority. When the transmission is not low latency and high priority the infringing AP may modify future transmissions based on the notification. When the transmission is low latency and high priority the infringing AP may notify the controller that the transmission is low latency and high priority. The controller may then create a negotiation between the victim AP and the infringing AP, wherein the negotiation comprises managing future transmissions of the victim AP and the infringing AP.

Abstract: A method includes determining, based on (i) a transmit time and a receive time of a request packet from a first access point (AP) to a client device and (ii) a transmit time and a receive time of a response packet from the client device to the first AP, a distance between the first AP and the client device and adjusting a transmit power of the first AP based at least in part on the distance between the first AP and the client device.

Abstract: Methods and a system described herein form collections of stations based on capabilities and classification of the station and on radio capacity and link budgets of the bands in which the stations operate. Once a collection is formed, a check occurs to determine if there is a rebalancing event, such as a change in the capabilities and classification of a station or a change in the radio capacity and link budgets. If so, then the stations are reassigned to different collections. If no rebalancing event occurs, then the assignment is checked to determine if the loads on the links are well-balanced. If so, a radio link recommendation is sent to the stations.

Abstract: A method includes transmitting a message over a first link using a first radio of a plurality of radios of a multi-link device and in response to determining that the message was not properly received, selecting a second radio of the plurality of radios of the multi-link device. A second link of the second radio provides a higher probability than the first link that the message will be properly received. The method also includes retransmitting the message over the second link using the second radio.

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: 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 device includes a memory and a hardware processor communicatively coupled to the memory. The hardware processor determines that a computing device communicatively coupled to an access point performed an action with respect to the access point and in response to determining that the action causes a deviation from a multi-user uplink policy of the access point, transmits a disciplinary message to the computing device.

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.
