Abstract: The Open Radio Access Network (O-RAN) paradigm introduces disaggregated and virtualized RAN elements connected through open interfaces, enabling AI-driven optimization across the RAN. It allows flexible energy management strategies by leveraging intelligent RIC (RAN Intelligent Controller), and computing continuum (Dew-Edge-Cloud) resources. The Open Radio Access Network (O-RAN) provides vendor-neutral, disaggregated RAN components and AI-driven control, making it a strong candidate for future networks. On the other hand, the transition to 6G networks requires more open, adaptable, and intelligent RAN architecture. Open RAN is envisioned as a key enabler for 6G, offering agility, cost efficiency, energy savings, and resilience. This paper assesses O-RAN’s performance in 6G mobile networks in terms of energy efficiency.
