Abstract

The Open Radio Access Network (O-RAN), an industry-driven initiative utilizes intelligent Radio Access Network (RAN) controllers and open interfaces to facilitate efficient spectrum sharing between LTE and NR RANs. In this paper, we harness O-RAN's capabilities to introduce the Proactive Spectrum Adaptation Scheme (ProSAS). This data-driven, O-RAN-compliant spectrum sharing solution is an intelligent radio resource demand prediction and management scheme for intent-driven spectrum management that minimizes surplus or deficit experienced by both RANs. We validate the effectiveness of this solution using actual LTE resource usage data and synthetically generated NR data. Lastly, we discuss the O-RAN-compliant architecture of the proposed solution.
