1. A method comprising:
establishing, by an access point (AP), a wireless communications link between the AP and a wireless station, wherein establishing the wireless communications link comprises receiving a protected association request frame from the wireless station, wherein the protected association request frame includes rotation pace preference information for randomized Media Access Control (MAC) address rotation management, wherein the rotation pace preference information indicates a preferred rotation pace;
selecting, by the AP, an Enhanced Data Privacy (EDP) group from one or more EDP groups based on the rotation pace preference information in the protected association request frame, the selected EDP group associated with epoch timing information for rotating wireless frame anonymization parameters at epoch transitions;
transmitting a response frame to the wireless station, wherein the response frame indicates the selected EDP group; and
maintaining, by the AP, the wireless communications link with the wireless station based at least in part on the timing information for randomized MAC address rotation for the selected EDP group.
