ProSAS: An O-RAN Approach to Spectrum Sharing between NR and LTE
This addresses efficient spectrum management for telecom operators using O-RAN, but appears incremental as it builds on existing O-RAN frameworks.
The paper tackles spectrum sharing between LTE and NR RANs by introducing ProSAS, a data-driven scheme that minimizes surplus or deficit in resource demand, using real-world LTE and synthetic NR data to demonstrate effectiveness.
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 introduce the Proactive Spectrum Adaptation Scheme (ProSAS), a data-driven, O-RAN-compatible spectrum sharing solution. ProSAS 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 illustrate the effectiveness of this solution using real-world LTE resource usage data and synthetically generated NR data. Lastly, we discuss a high-level O-RAN-compatible architecture of the proposed solution.
