CLO5ER: a Composable Lightweight Observability for 5g RAN Environment Inside Near RT RIC

The Open RAN specification introduces the Near Real-Time RAN Intelligent Controller (Near-RT RIC) as a closer point of orchestration, providing real-time analysis and control of gNBs through Operator-defined Near-Real Time Applications (xApps).

GradFA: A Unified Gradient-Based Attribution Framework for Backdoor Detection and Mitigation in DRL-Based O-RAN xApps

IEEE Open Journal of the Communications Society
The Open Radio Access Network (O-RAN) xApp marketplace lets operators deploy third party deep reinforcement learning (DRL) applications into the Near-Real-Time RAN Intelligent Controller (Near-RT RIC), yet provides no way to verify the integrity of a ...

ISAC-Assisted DRL for Dynamic MAC Scheduler Reconfiguration in O-RAN

IEEE Open Journal of the Communications Society
This paper introduces reconfiguration mechanisms for a 5th Generation (5G) Medium Access Control (MAC) scheduler, which uses Deep Reinforcement Learning (DRL) and is deployed as an xApp within the RAN Intelligent Controller (RIC) framework. The objective

Inter-xApp Policy Conflicts in the O-RAN Near-RT RIC: Threat Modeling, Attack Characterization, and Lightweight Conflict-Aware Mitigation

IEEE Access
With the advent of the disaggregated, multi-vendor design of the Open Radio Access Network (O-RAN), third-party applications (xApps) can drive closed-loop control through the near-real-time RAN Intelligent Controller (near-RT RIC).
