This talk will introduce the 6G research group in the O-RAN Alliance. The O-RAN Alliance defines technical specifications for O-RAN systems. For the first time, a standard body for telecommunication has established a research group to bridge the work between industry and academia. The research group provides a collaborative platform to work on key research topics for next-generation radio access networks (RAN). It has identified five prioritized research areas, which include 6G use cases and requirements, architecture, native AI, security, and 6G research platforms. The main activities in each research area will be introduced, and the key outcomes will be highlighted. The research group is open to academia and calls for contributions to shape the evolution of O-RAN towards 6G. In addition to the overview of the 6G research group, this talk will provide a detailed research work on distributed ML for resource allocation in O-RAN systems. It shows that deep reinforcement learning has the potential to improve the system performance in a disaggregated RAN.
Dr. Tao Chen is a principal scientist at VTT Technical Research Centre of Finland and the co-chair of the next generation research group (nGRG) in the O-RAN Alliance. He has been working in the telecommunication sector for over two decades and has extensive experience leading large research and development projects in Europe. Currently, he is leading the EU SNS 6G project 6G-Cloud, which is one of five system architecture projects in the second phase of the EU 6G research program. Back in 2015, Dr. Chen led an EU project team building the world’s first RAN intelligent controller concept, which has been the key concept in O-RAN. Dr. Chen is a Royal Academy of Engineering visiting professor at the University of Kent, UK, and an associated professor (Docent) at the University of Jyväskylä, Finland. He acts as the associated editor-in-chief of IEEE Wireless Communications Magazine and has served as a technical editor of IEEE Transactions of Cognitive Communications and Networks. Dr. Chen has published more than 80 scientific publications. His current research interests include RAN cloudification, software networking for 5G/6G mobile networks, dynamic spectrum access, AI/ML in wireless networks, energy efficiency, and resource management in heterogeneous wireless networks.
