The apparatus sends a request from a medium access control (MAC) layer to at least one of a Physical (PHY) Layer or a radio frequency (RF) component using an application protocol interface (API) and receives a response message from the at least one of the PHY layer or the RF component comprising an hierarchical indication of at least one capability of the PHY layer or the RF component using the API. The apparatus may also configure the PHY layer or the RF component based on the at least one capability.
