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.

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.
