  • Patent number: 11924898
    Abstract: Some embodiments include utilizing a multilink media access control (MAC) address structure to support multilink devices (MLDs) that can operate concurrently in more than one link such as extremely high throughput (EHT) access points (APs) and EHT stations (STA), where the multilink MAC address structure is compatible with legacy devices. An EHT AP can utilize a multilink basic service set (BSS) identification (BSSID) MAC address to communicate with an EHT STA identified by a multilink MAC address. Values of the multilink BSSID and the multilink MAC address of the EHT STA are independent of which of the multiple links are used in the communication. In addition, to utilizing a multilink BSSID, the EHT AP can also support unique link-specific MAC addresses to concurrently support legacy and MLD stations. The EHT STA can also utilize unique link-specific MAC addresses that can be different than the EHT AP's link-specific MAC addresses.

  • Publication number: 20240015608
    Abstract: Embodiments are disclosed for station (STA) identifier opt-in. Some embodiments include a STA that can associate with an access point (AP) of a wireless network, where the STA is configured to opt-in to being identified by the AP. The STA can transmit a first message 2 (M2) of a 4-way handshake protocol during the association, where the first M2 includes a Device Identifier (ID) Key Data Encapsulation (KDE) that includes an Opt-in Control field, where a first value of the Opt-in Control field indicates the STA opts-in to being identified by the AP. The STA can receive a first message 3 (M3) of the 4-way handshake protocol including a Device ID KDE and an ID Blob, where the ID Blob corresponds to the STA. The STA can communicate with the AP, where the first value enables the AP to collect data about the STA during the communication.

  • Publication number: 20230353339
    Abstract: A method and apparatus for synchronizing a timebase is disclosed. A timebase management circuit includes limit circuitry, in a first clock domain, which generates, based on a global timebase, an initial timebase limit. The timebase management circuit includes, in a second clock domain, adjustment circuitry that generates an adjusted timebase limit based on the initial timebase limit. A storage circuit in the second clock domain stores a local timebase. Update circuitry, coupled to an output of the storage circuit, generates an updated local timebase using a clock signal in the second clock domain, wherein the updated local timebase is subject to the adjusted timebase limit.

  • Publication number: 20230319688
    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: 20230232218
    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: 11687115
    Abstract: An apparatus for time management of a peripheral device is disclosed. A peripheral interface circuit receives information from a host circuit over a peripheral bus, the host circuit maintaining a global timebase in accordance with a first clock signal within a first clock domain. The peripheral interface circuit maintains, based om a second clock signal within a second clock domain, a first local timebase correlated to the global timebase. A peripheral control circuit operates in a third clock domain and maintains a second local timebase based on the first. The peripheral interface circuit determines phase and frequency differences between the second and third clock signals in determining a correlation between the second and first local timebases. A peripheral logic circuit in the third clock domain performs, operations that utilize a timestamp from the second local timebase, which accounts for correlation with the first local timebase.

  • Publication number: 20230144897
    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.

    Abstract: One or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A wireless station may enter an unsynchronized discovery mode, transmit, in response to receiving a subscribe message from a neighboring device, a publish message to the neighboring device, perform authentication and trusted device cluster provisioning with the neighboring wireless device, and protect transmissions using the security credentials. In the unsynchronized discovery mode, the wireless device may monitor a discovery channel for subscribe messages, e.g., from neighboring peer devices. Additionally, the trusted device cluster provisioning may provide security credentials to the wireless device.
