Researchers from Nokia, Ericsson, Fraunhofer, Bosch, and RPTU Kaiserslautern-Landau propose a 6G Radio Access Network (RAN) architecture that simplifies the functional design and protocol stack, aiming for improved operational and energy efficiency. This approach avoids 5G's higher layer splits and multi-layer retransmissions, while integrating O-RAN, network slicing, and a zero-trust framework for enhanced flexibility and trustworthiness.
Key insights
- Simplifying the functional architecture and protocol stack, rather than increasing complexity, is crucial for improving 6G RAN operational and energy efficiency.
- Decoupling the functional architecture from underlying infrastructure through open interfaces (like RU-RANF LLS) enables greater deployment flexibility, vendor independence, and cloud-native implementations.
- Integrating AI/ML-driven intelligence (O-RAN RIC), end-to-end orchestration, and robust security (zero-trust) are essential for managing and securing a flexible, performance-driven 6G ecosystem.
