  • Patent number: 12689969
    Abstract: The present disclosure provides techniques for transport mode selection based on MAPC deployment. A network device receives information from one or more other network devices within a CG, where the CG is configured to operate using a MAPC mode, and the information indicates a support of acting as a transport node over wired connections and a MAPC transport role within the CG for each of the other network devices. The network device estimates a wired path between the network device and at least one of the other network device, and determines transit times required for communication over the wired paths and transit times required for communication over wireless paths. Considering the transit times for the wired and wireless paths and the MAPC mode, the network device selects a transport mode, communicates the transport mode to the other network devices, and performs a network coordination operation using the transport mode.

  • Publication number: 20260190024
    Abstract: Techniques and apparatus for scheduling coordinated restricted target wake times (Co-RTWTs) with jitter are described. An example technique includes determining a schedule of service periods allocated to at least one of (i) one or more access point (AP) devices or (ii) one or more aggregated flows associated with the one or more AP devices. A first service period allocated to a first AP device for exchanging first traffic is determined based on the schedule of service periods. Upon determining, in the first service period, that a second AP device has second traffic that satisfies a predetermined condition, a portion of the first service period is allocated to the second AP device for communicating the second traffic.

  • Publication number: 20260156639
    Abstract: Techniques for improved peer-to-peer communication are provided. A wireless access point (AP) may initiate peer-to-peer communication between multilink peer-to-peer devices by sending a trigger frame addressed to the peer-to-peer devices to hand over a transmission opportunity (TXOP). The trigger frame is sent based on the AP's knowledge of the availability of the peer-to-peer devices for peer-to-peer communication. The trigger frame indicates a link to be used for the peer-to-peer communication. In response to receiving the trigger frame one or more of the peer-to-peer devices acknowledge the trigger frame, tune to the assigned link, and use the remaining portion of the TXOP for peer-to-peer communication.

  • Publication number: 20260156673
    Abstract: An AP may want to change the non-primary channel access (NPCA) primary channel (NPCH) when the primary channel for the BSS is unavailable, e.g., due to interference on the current NPCH or as a result of RRM. The embodiments herein describe techniques to coordinate the NPCH change and announce it in advance so that both the access point (AP) and stations (STAs) start using the new NPCH at the same time. That is, the embodiments herein describe mechanisms where both the AP and associated STAs start using the new NPCH at the same time when the NPCH changes.

  • Patent number: 12648024
    Abstract: A signaling mechanism is provided that includes a restricted random access resource unit (XRA RU) that restricts uplink random access, such as by using Uplink Orthogonal frequency-division multiple access-based Random Access (UORA), to a subset of a plurality of stations that are associated with an Access Point (AP). In one aspect, an AP allocates a resource unit as an XRA RU that restricts uplink random access to a subset of a plurality of stations (STAs) that are associated with the AP. The AP transmits an uplink trigger that includes the XRA RU. The AP restricts use of the XRA RU to the subset of the plurality of STAs. In this way, STAs of the subset can attempt contention-based random access with the XRA RU while other STAs are prevented from attempting random access with the XRA RU.

  • Publication number: 20260129452
    Abstract: Detection of rogue access points (APs) through an AP that is associated with a mobility domain in a network. Unvalidated APs that attempt to join the network may be validated by another AP that is associated with the network. The unvalidated and associated APs may exchange signatures to determine if the unvalidated AP knows a key associated with the network. If the unvalidated AP does not know the key, the unvalidated AP is not validated for the network. The AP that was doing the validation may transmit a message to devices on the network indicating a rogue AP, the unvalidated AP, is attempting to join the network.

  • Publication number: 20260129453
    Abstract: The present disclosure provides techniques for mitigating Man-in-the-Middle (MITM) and replay attack within a mobility domain. An access point (AP) within a seamless mobility domain (SMD), generates a frame comprising an SMD signature, an SMD identifier, and a replay protection value, where the SMD signature is generated by signing a data structure comprising the SMD identifier and the replay protection value using a private key associated with the SMD. The AP transmits the frame to a station (STA) for verification.

  • Publication number: 20260129535
    Abstract: Combining MBSSID sets, co-hosted BSSID sets, and standalone VAPs into a co-located, co-channel BSSID set to allow for more efficient communication between different members of the co-located, co-channel BSSID set. By combining the members into the co-located, co-channel BSSID set, when a TXOP holder provides transmission time to a co-located, co-channel BSSID set, each of the VAPs in the co-located, co-channel BSSID set receives access to exchange data for a duration of time. When the co-located, co-channel BSSID set indicates to the TXOP holder that the VAPs finished exchanging data, each of the VAPs in the co-located, co-channel BSSID set loses access to send data.
