Title: Architecture to shape the 6G future
Abstract: The evolution of architecture will shape the 6G future characterized by the interplay of network and digital economy. Key value drivers will include sustainability, security and privacy as well as digital inclusion and with broad impact on a variety of ecosystems. In this keynote the network architecture for the 2030s will be described. 6G architectural principles will be analyzed. Pivotal enabling architectural attributes such as AI nativeness, energy efficiency, multi-cloud nativeness, open and flexible programmability as well as security and trust will be highlighted. We need clarity on 6G “Day 1” readiness requirements to assure an architectural evolution for smooth migration anchored in simplicity while assuring basic functionality. 6G architecture will enable use case phasing with initial focus on immersive MBB, XR and dependable RT, 3D networks (TN/NTN), low Power LAN & WAN IoT as well as lean Industrial IoT. Simplification means SA-only architecture. However, architectural evolution does not stop there and innovative options for 6G architectural innovation beyond Day 1 deserve attention in dimensions such as novel network functional paradigms, Cloud&Network OS, Cloud Network fusion, Cloud RAN architecture, RAN-CN interface as well as integrated communications and sensing. New architectural options under study include novel RAN-CN along with distributed NAS, evolution of User Plane, network slicing and QoS/QoE framework evolution as well as the option of specialized sub-networks. Collaboration and interoperability are key and now is the time to jointly create the architectural platform that will form the basis for 6G standardization.
