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.
