Model pairing for backward compatible models

Abstract

Certain aspects of the present disclosure provide wireless communications at an apparatus (e.g., a UE or UE side training entity). According to certain aspects, the apparatus obtains first signaling indicating 1) first parameters associated with a first pairing of a first machine learning (ML) model usable at the apparatus and a second ML model usable at a wireless node, and 2) an association between at least one of the first ML model or second ML model and at least one of a third ML model usable at the apparatus or a fourth ML model usable at the wireless node, wherein the third ML model and fourth ML model are associated with a second pairing; and performs one or more actions based on the association.
