Abstract

Aspects of the disclosure are directed to prediction of a predicted material profile of the target object based on measurement information associated with sensing (RF-S) signal(s). In an aspect, one or more actions are performed in response to the predicted material profile of the target object, the one or more actions including, e.g., constructing at least one digital twin associated with the target object based on the predicted material profile of the target object, or modifying operation of a wireless communications network, or a combination thereof. Such aspects may provide various technical advantages, such as more accurate digital twin generation (e.g., digital twins may be updated to reflected material profiles of objects detected in real-world), improved network operation (e.g., permit line of sight (LOS) through objects with certain material profiles, block LOS through objects with other material profiles, etc.), and so on.
