1. A privacy enhanced (PE) access point (AP) multi-link device (MLD), comprising:
one or more affiliated APs operating on different links; and
a processor coupled to the one or more affiliated APs, configured to:
generate a first over the air (OTA) MLD address based at least on an MLD address of the PE AP MLD, for a first affiliated PE AP (PE AP1) of the one or more affiliated APs, wherein the first OTA MLD address is different than a second OTA MLD address for a second affiliated PE AP (PE AP2) of the one or more affiliated APs;
encrypt an aggregated Media Access Control (MAC) service data unit (A-MSDU) for transmission to a first PE non-AP station (PE non-AP STA1) of a PE non-AP MLD, the A-MSDU comprising a packet number (PN);
after the encryption, create an OTA packet number (PNOTA) that is different than the PN corresponding to the A-MSDU, wherein a first data transmission comprises the PNOTA; and
transmit the first data transmission using the first OTA MLD address, wherein the first data transmission comprises a subframe of the A-MSDU that includes the MLD address.
