This research report explores how future 6G networks can be built on scalable and user-centric RAN architectures, focusing on the principles and technologies required to support increasingly diverse services and highly dynamic traffic patterns. As devices and applications grow more varied, next-generation RANs should adapt quickly, allocating resources elastically, distributing intelligence closer to users, and operating with greater energy efficiency.
The report outlines key design considerations for cloud-native and virtualized O-RAN deployments, in which O-DUs, O-CUs, and hardware accelerators can be flexibly deployed, shifted, or powered down based on real-time demand. It also examines how AI-driven orchestration can strengthen scalability, enhance resilience, and tailor Quality of Experience (QoE) to individual users.
Beyond this, the report highlights the potential of Distributed MIMO (D-MIMO) and cell-free architectures, the benefits of advanced acceleration technologies, and the value of energy-aware, multi-tenant compute platforms.
Together, these insights present a cohesive framework that unifies communication and computation to deliver more personalized performance, higher spectral efficiency, and robust network operation. Ultimately, the report offers guidance to support the evolution of O-RAN ALLIANCE technologies toward more adaptive, sustainable, and user-centric RAN designs for the 6G era.
