  • Publication number: 20240089854
    Abstract: In embodiments of the present disclosure, there is provided an approach for aligning target beacon transmission time (TBTT) for multi-link connection. A method comprises setting up a first link and a second link between an access point (AP) and a wireless device based on multi-link operation (MLO), and obtaining a first TBTT of the first link and a second TBTT of the second link. The method further comprises aligning the first TBTT and the second TBTT at a start time, and then transmitting beacon frames on the first link and the second link according to the aligning of the first TBTT and second TBTT. Embodiments of the present disclosure synchronize and align the beacon TBTTs for different links, and can reduce the wake-up time on all active links, thereby saving power for the wireless device.

  • Publication number: 20240040488
    Abstract: Systems and methods are provided for ensuring client device connectivity in a deployment pursuant to regulatory updates impacting channel usage or availability. An access point (AP) or AP controller may obtain a client-supported channel list, and detect existence of a regulatory update impacting channel usage in the network device. An AP-supported channel list is compared to the client-supported channel list, and a determination is made regarding which client devices associated to an AP do not support channel usage changes resulting from the regulatory update. Distribution of channels of the AP-supported channel list is controlled among one or more radios of APs in a deployment based on AP density of the deployment, and the determination regarding which client devices do not support the channel usage changes.

  • Patent number: 11855777
    Abstract: In embodiments of the present disclosure, there is provided an approach for selecting a channel puncturing scheme based on channel qualities. A method comprises detecting channel interference between neighbor access points (APs), and determining whether a preamble puncturing needs to be enabled based on some puncturing conditions. After determining that a preamble puncturing needs to be enabled, scores for candidate puncturing patterns are calculated based on channel qualities of the sub-channels in the channel, and a proper puncturing pattern can be selected based on the respective scores. Embodiments of the present disclosure can help AP to achieve an effective and better puncturing scheme in real deployment.

    Abstract: Examples described herein relate to a method for managing association of a client device with a virtual access point (VAP) hosted on an access point (AP). The method includes monitoring, by the AP, data traffic corresponding to the client device associated with a first VAP. The first VAP is mapped to a first Multiple Basic Service Set Identifier (MBSSID) set configured with a first quality of service (QoS) parameter. The AP also hosts a second VAP mapped to a second MBSSID set configured with a second QoS parameter. Further, the AP determines a communication demand of the client device based on the data traffic. Furthermore, the AP steers the client device to the second VAP based on the communication demand and the second QoS parameter, and communicates with the client device through the second VAP.

  • Publication number: 20230403582
    Abstract: In embodiments of the present disclosure, a method is provided for interference mitigation in wireless communication. Radio statistics indicating transmissions between an AP and a plurality of clients are obtained at the AP. Based on the radio statistics, a client suffering from adjacent band interference is identified from the plurality of clients. An indication is transmitted to at least one other client of the plurality of clients to mitigate the adjacent band interference and the at least one other client is identified based on the client. In this way, by transmitting the indication to the client(s) associated with the client identified as suffering from the adjacent band interference, the adjacent band interference can be mitigated or eliminated efficiently.

  • Publication number: 20230379801
    Abstract: Systems and methods are provided for multiple basic service set identifier (MBSSID) beaconing (from an access point (AP) standpoint) and MBSSID/virtual AP (VAP) scanning (from a client device perspective). To facilitate easier discovery of mesh APs/VAPs, BSSIDs associated with mesh VAPs can be advertised more frequently, e.g., being broadcast as a transmitted or non-transmitted BSSID in each MBSSID beacon. Additionally, information regarding mesh VAPs, such as mesh capability information, can be provided via intermediate discovery beacons or frames such that out-of-band scanning mechanisms can discover mesh VAPs faster. Additionally still, the existence of mesh VAPs can be advertised in a dedicated field of an MBSSID beacon.

  • Publication number: 20230370952
    Abstract: Examples described herein relate to a method for reconfiguring a beacon by an access point (AP) to minimize or avoid network outages experienced by client devices connected to the AP. The AP transmits a beacon comprising a basic service set identifier (BSSID) field and a Multiple BSSID (MBSSID) element. The MBSSID element corresponds to an MBSSID set comprising a transmitted BSSID associated with a transmitted virtual access point (VAP) and a non-transmitted BSSID associated with a non-transmitted VAP, where the BSSID field in the beacon is set to the transmitted BSSID. Further, the AP reconfigures the beacon to generate a reconfigured beacon upon determining that the transmitted VAP is non-functional. In particular, the BSSID field in the reconfigured beacon is set to the non-transmitted BSSID of the MBSSID set. Moreover, the AP transmits the reconfigured beacon to the client device.

  • Patent number: 11805571
    Abstract: In embodiments of the present disclosure, a method is provided for managing a mesh point. A request is transmitted from a mesh point to a mesh portal, and the request indicates that Reduced Neighbor Report (RNR) information is required. A beacon with the RNR information is received from the mesh portal. A mesh link is established with a target mesh portal based on the beacon with the RNR information. Therefore, the time cost and the data communication of a scanning procedure of the mesh point may be greatly reduced.
