About this paper
Hengxu Li, Dongkuan Xu, Mingzhe Chen, Yuchen Liu
Researchers from Tufts University, North Carolina State University, and the University of Miami present A1GENT, an agentic Open RAN control framework that translates natural language operator intents into deterministic, auditable low-level radio access network actions. In simulated urban traffic surge scenarios, it improved the 10th percentile downlink throughput for the weakest users by 20% and reduced network outage by 1.5 percentage points, while enhancing mobility stability.
Key insights
- Decoupling LLM-driven intent reasoning (second-to-minute horizon) from deterministic near-RT execution (millisecond horizon) enables the integration of advanced AI into safety-critical network control.
- Formalizing A1 policy types and instances with IaC-encoded guardrails and conflict management provides a robust mechanism for verifiable and auditable AI decisions in Open RAN.
- A training-free, memory-driven Adaptive Policy Tuner allows for practical and explainable adjustments to network parameters, reducing the need for continuous model retraining in dynamic environments.
