What are the innovative points of the 8 major white papers
At the meeting, China Mobile released 8 white papers on key 6G technologies, including “Development Trends of 6G Holographic Communication Business”, “6G to Simplified Wireless Access Network”, “6G Service based RAN”, “Autonomous 6G Wireless Network Based on Digital Twin Network”, “Architecture and Technology of 6G Wireless Intrinsic AI”, “Key Technologies of 6G Physical Layer AI”, “6G Information Metamaterial Technology”, and “6G Visible Light Communication Technology”. Yi Zhiling, Chief Scientist of China Mobile Research Institute, stated that these 8 6G key technology white papers have received strong support from four partners and relevant experts, including Tsinghua University, Beijing University of Posts and Telecommunications, Southeast University, and Zhongguancun Innovation Institute.
“What new modes of business will emerge in the 6G era is something that everyone is very curious about. We believe that holographic communication services can provide the ultimate experience of highly immersive natural interaction, which will be a major mode in the future.” Yi Zhiling said that the “Development Trends of 6G holographic communication services” white paper focuses on the three stages of holographic communication development: optical stage, digital stage, and computing stage, extracting eight typical features and related key technologies; We have also identified key network requirements and technological bottlenecks for the seven major application scenarios of human, machine, object, and environment collaboration.
Various new businesses and scenarios will bring new demands and challenges to 6G networks. How to simplify the network and strengthen functions while meeting diverse needs is the main research topic of the white paper “6G to Simplified Wireless Access Network”. The white paper preliminarily proposes new architectural ideas, including the decoupling of signaling cells and data cells and related flexible link adaptation, as well as key technologies including plug and play management orchestration.
The white paper “6G Service based RAN” is a fundamental IT technology roadmap that continues virtualization and cloud technology. Yi Zhiling said that this evolutionary path is gradually infiltrating from the core network to the access network, ultimately aiming to achieve end-to-end overall efficient resource dynamic sharing. This white paper analyzes and considers from the perspective of protocol stack how to provide a virtualized and cloud to service-oriented wireless access network architecture, which includes interfaces, control surfaces, user surfaces, and extends to the integration of terminal, ICDT, and even OT technologies.
China Mobile released its first white paper on digital twin networks last year. The publication of “Autonomy of 6G Wireless Networks Based on Digital Twin Networks” is based on the previous architecture of digital twin networks and proposes a basic concept of “Three Body, Five State, and Double Closed Loop”. It systematically elaborates on the concept and technical characteristics of digital twin networks to achieve efficient closed-loop and autonomous capabilities throughout the entire lifecycle of 6G networks, hoping to use this technology to achieve the goal of efficiency improvement and cost reduction.

The white paper “Architecture and Technology of 6G Wireless Endogenous AI” further introduces new resource dimensions such as models, examples, and data. On the basis of expanding the control surface and data surface, it also adds architectural considerations for intelligent surface, data surface, and computing surface, and proposes some new technologies. Yi Zhiling stated that this is a very important milestone and hopes that the architecture and technology of wireless endogenous AI can truly be implemented before 2030.
The white paper “Key Technologies of 6G Physical Layer AI” proposes a method for constructing datasets, as well as evaluation criteria, indicators, and how to generalize these solutions, with a particular focus on enhancing MIMO technology by introducing AI. At the same time, it further clarifies and strengthens China Mobile’s consistent advocacy of data and model dual drivers. After the introduction of artificial intelligence and machine learning technologies in the physical layer, will there be different ways of thinking in the future standardization of the physical layer? In addition to considering the necessity of data collection, there are also considerations that can provide greater flexibility due to the introduction of machine learning and artificial intelligence, and we hope to simplify the standardization of the physical layer in the 6G era.
6G information metamaterial technology is currently a technology that has attracted global attention. Yi Zhiling stated that the White Paper on 6G Information Metamaterial Technology takes a very practical perspective to consider the challenges and limitations of materials, devices, and system scenarios in all aspects. The white paper proposes a three-step working mode, with the first step being a static and semi-static working mode; The second step is to operate in channel transparency mode, which may have certain limitations in performance and functionality; The ultimate mode of the third step is channel opacity. The white paper also points out the relevant challenges and potential limitations.
Visible light communication has been studied by many scientists during the 4G and 5G periods. Yi Zhiling said that based on the research of many partners, “6G Visible Light Communication Technology” not only analyzes the challenges of visible light in devices and transmission, but also focuses on networking considerations. It proposes wireless and optical fusion networking, hoping that visible light communication technology can play its due role in the 6G era.
