  • Publication number: 20240080924
    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: Time Sensitive Networking (TSN) Quality of Service (QoS) in overlapped administrative domains may be provided. A first Access Point (AP) may detect at least a second AP in a Co-Channel Interference (CCI) range. A micro-transaction auction between the first AP and at least the second AP may be established, and the first AP may provide compensation to second AP to acquire an agreement, from the second AP, to forgo transmitting during an upcoming service period. Next, the first AP may schedule transmissions for the service period and then transmit in the service period without interference from the second AP.

  • Publication number: 20240049133
    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.

  • Publication number: 20240023179
    Abstract: An arrangement of three radios maybe provided. The three radios define first and second outer data links and a middle data link. Access to the arrangement of three radios can be biased to the middle data link in one direction upon a data transmission through the first and second outer data links being dominate in an opposite direction. Data transmission with enhanced multi-link single radio (eMLSR) client devices can be prioritized lower than data transmission with simultaneous transmit and receive radio (STR) client devices and non-simultaneous transmit and receive radio (NSTR) client devices. A radio can be configured for data transmission with a client device. The range of the radio is limited when the data traffic through the radio exceeds a determined number of bytes of data in a determined amount of time.

  • Publication number: 20240015592
    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.

  • Publication number: 20240015789
    Abstract: Described herein are systems and methods for reducing collisions in a wireless network with overlapping basic service sets by synchronizing contention slots among stations (access points or non-access point clients), some of which are out of range, competing for the use of the wireless medium. In some embodiments, the contention slots of competing stations are synchronized by controlling the time of transmission and the time of the spacing between frames to be an integer multiple of the time of a contention slot. In some embodiments, slot boundaries are enforced by controlling guard intervals or by trigger-based uplink communications. In other embodiments, a central network controller, such as a network controller, synchronizes slots when an access point or station joins the wireless network or uses a neighbor discovery protocol among access points. The contention slots are synchronous in all cases throughout the overlapping basic service sets.

  • Publication number: 20240015642
    Abstract: A system includes a memory and a processor communicatively coupled to the memory. The processor, in response to determining that a first number of transmissions over a first link with a first frequency has failed, selects a second link with a second frequency for transmission. The second frequency is lower than the first frequency. The processor also, in response to determining that a second number of transmissions over the second link has failed, one or more of (i) stop the transmissions over the second link or (ii) begins transmissions over a third link with a third frequency. The second number is greater than the first number.
