ProSAS: An O-RAN Approach to Spectrum Sharing between NR and LTE
arxiv(2024)
摘要
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.
