Abstract
Techniques are directed to using communication metric data associated with multiple modulation schemes to achieve a link quality metric that is representative of the link as a whole, across the multiple modulation schemes that may be employed on the link. A calculation of a link quality metric may be triggered by a network layer transmission attempt, with communication metrics accumulated at the link layer of the link. A filter used to calculate the link quality metric may be updated based on network layer transmission attempts, based on successful and/or unsuccessful transmissions at a Media Access Control (MAC) layer of the link. More generally, a calculation of link quality may be triggered by a higher layer transmission attempt while being calculated based on transmission attempts at a lower layer of the link.
