1. An access point (AP) configured to support a high priority (HP) service, comprising:
a transceiver configured to:
announce first enhanced distributed channel access (EDCA) parameters for a first device associated with the AP, wherein the first EDCA parameters support the HP service;
announce second EDCA parameters for a second device associated with the AP that does not support the HP service;
receive a HP priority access request frame from the first device configured to request HP services; and
transmit an HP priority access response frame to the first device enabling HP traffic transmission by the first device,
wherein the AP is a multi-link device (MLD), and wherein enabling HP traffic transmission by the first device is based upon a traffic specification (TSPEC) of a requested HP traffic such that when a mean data rate of a specific HP service is more than a value, the specific HP service is not enabled.
