arXiv:2605.30622v1 Announce Type: cross Abstract: Open radio access network (O-RAN) architectures enable near real-time, software-driven control of network slicing through programmable xApps deployed on the near-real-time RAN Intelligent Controller (near-RT RIC). In industrial 5G downlink systems, adversarial jamming can abruptly reduce the effective physical resource block (PRB) capacity, triggering queue buildup and persistent latency violations, particularly in the presence of low spectral efficiency cell edge user equipments. This paper proposes a reserve-based resilience framework for PRB
The increasing reliance on 5G for industrial applications and critical infrastructure highlights the immediate need for resilient network architectures against new forms of cyber and physical interference.
Ensuring the robustness of O-RAN networks against jamming is crucial for the reliability of next-generation industrial and defense applications that depend on low-latency communication.
This research introduces a novel framework for reserving physical resource blocks to maintain network performance, shifting the paradigm towards proactive resilience in 5G slicing.
