  • Patent number: 12659837
    Abstract: Systems, methods, and mechanisms for a privacy enhanced basic service set (BSS), including privacy enhancements for both access points and wireless stations as well as privacy enchantments for authentication, association, and discovery operations. Further, the systems, methods, and mechanisms disclosed may continue to support legacy wireless stations and are thus, backward compatible. A non-associated PE station may receive, from a PE access point, one or more discovery beacons advertising PE BSSs hosted by the PE access point and transmit, to the PE access point, a request to setup pre-association security protection. The non-associated PE station may, upon setup of pre-association security protection, transmit, to the PE access point, a protected request frame and receive, from the PE access point, a protected response that includes PE access point parameters.

  • Patent number: 12652607
    Abstract: Embodiments are disclosed for privacy enhancement (PE) beacon frames. A PE station (STA) can receive a PE beacon frame comprising a media access control (MAC) header that includes a first random identifier (ID) and a first checksum ID, determine that configured beacon parameters are satisfied, and then receive the PE beacon frame. When the first random ID and the first checksum ID correspond to an affiliated PE access point (AP) of a PE AP multilink device (MLD), to identify the PE AP MLD the PE STA can determine a checksum value using a AP MLD ID of the PE AP MLD and the first random ID, and based on a comparison of the determined checksum value with the first checksum ID, identify the PE AP MLD. In some embodiments, a location of a change sequence number adjacent to the MAC header enables early termination of the PE beacon frame reception.

  • Publication number: 20260129547
    Abstract: Methods and systems describe herein relate to a reconfigurable multi-radio bridge that may connect a local area network (LAN) with an access point (AP) or other WAP to the backhaul and may dynamically change and/or select transmission methods. An example implementation of a reconfigurable multi-radio bridge performs a method including discovering a topology of a network that includes one or more wireless stations (STAs), evaluating a metric for each of at least two routes discovered in the topology, receiving a packet that identifies a first STA of the one or more STAs as an intended destination of the packet, selecting a route of the at least two routes over which to send the packet based on the metric, and sending the packet from a reconfigurable multi-radio bridge over the selected route toward the first STA.

  • Publication number: 20260106656
    Abstract: Example implementations are directed to methods and systems employing a solicited sounding protocol that includes an efficient communication sequence for operating a wireless transceiver transmitting a sounding trigger to one or more beamformees via a forward channel, receiving at least one dedicated training signal from the one or more beamformees via a reverse channel in response to the sounding trigger, and for each of the received dedicated training signal. The method also includes estimating forward CSI derived based on the dedicated training signal from an associated beamformee; and where subsequent packets are precoded with precoding derived from the forward CSI for transmission to the associated beamformee via the forward channel. Example aspects including scheduling multiple dedicated training signals from one or more beamformees based on a single sounding trigger.

  • Patent number: 12513512
    Abstract: Embodiments are disclosed for encrypting media access control (MAC) Header fields for Wireless LAN (WLAN) privacy enhancement. For example, a transceiver of a station (STA) or an access point (AP) can set a real time Media Access Control (MAC) header bit in a payload of an aggregated MAC Protocol Data Unit (A-MPDU) subframe to an actual value of a power management (PM) field of a MAC header of the A-MPDU subframe. The transceiver can encrypt the payload, set the PM field to an over the air (OTA) PM value, and transmit the A-MPDU subframe over the air. The OTA PM value can include all zeros, a predetermined value, or a randomized value The transceiver can also set static MAC header bits in the payload of the A-MPDU subframe to corresponding actual values of an aggregated MAC service data unit (A-MSDU) present field of the A-MPDU subframe.

  • Patent number: 12439241
    Abstract: Embodiments are disclosed for address changing schemes for a multi-link device in a wireless communications system. Some embodiments include a privacy enhanced (PE) access point (AP) multi-link device (MLD) that includes one or more affiliated APs operating on different links. The PE AP MLD can generate a first randomized OTA MLD address based at least on the MLD address of the PE AP MLD for a first affiliated PE AP (PE AP1). The PE AP MLD can transmit a first data transmission using the first OTA MLD address where the first data transmission includes an encrypted aggregated MAC service data unit (A-MSDU) subframe that includes the MLD address. The PE AP MLD can correlate the MLD address of the PE AP MPL with multiple addresses comprising: the first OTA MLD, a unique MLD address, and a Media Access Control (MAC) service access point (SAP) MLD address.

  • Patent number: 12401992
    Abstract: Embodiments are disclosed for address changing schemes in a wireless communications system. Some embodiments include an access point (AP) that can establish two or more address profiles with a station (STA), establish a schedule for switching from a first address profile to a second address profile, where the first and second address profiles are of the two or more address profiles, and transmit a first data transmission using the first address profile. Some embodiments include switching from the first address profile to the second address profile based on the schedule, and transmitting a second data transmission using the second address profile. The schedule can be based on a randomized time synchronization function (TSF). The AP can establish a joint algorithm with the STA, and use the joint algorithm determine the first and the second address profiles as well as transition times for the schedule.

  • Publication number: 20250203508
    Abstract: Embodiments herein include a method for selectively operating a software enabled access point (Soft-AP) in a low-power listen mode. In some embodiments, a Soft-AP may use a low-power listen mode with limited or no transmit capabilities to monitor a wireless medium when not actively engaged in transmission or reception of frames. The Soft-AP may activate a fully-capable mode when there is an upcoming frame transmission from a station.

  • Publication number: 20250159533
    Abstract: Wireless stations and access points may perform a wireless local area network (WLAN) sensing operation using a basic sensing by proxy (SBP) procedure driven by an SBP responder, in which case the sensing features associated with the SBP procedure are dictated by the SBP responder, or driven by an SBP initiator, in which case the sensing features are dictated by the SBP initiator. For an SBP responder driven SBP procedure, the SBP session may be requested with a reduced number of parameters that include number of respondents and maximum bandwidth. For an SBP initiator driven SBP procedure, suitable sensing responders may be identified and instructed prior to receiving a sensing request. The WLAN sensing session may be paused to enter doze mode during which no sensing frame exchanges take place between participating nodes and the WLAN sensing session does not expire and is not terminated, and may resume upon exiting doze mode.
