Recently, the IMT-2030(6G) Promotion Group of the Ministry of Industry and Information Technology officially released the "6G Overall Vision and Potential Key Technologies" white paper, proposing that 6G will expand from serving people, people and things to support based on 5G. The efficient interconnection of intelligent bodies will realize the leap from the interconnection of all things to the intelligent connection of all things, continue to improve people's quality of life, and promote the transformation and upgrading of social production methods.
"The 6G network is not only the link between the physical world and the digital world, but also the nervous system between the physical world and the smart world." said Tong Wen, chief technology officer of Huawei Wireless. The white paper proposes eight potential business application scenarios for 6G, including immersive cloud. XR, holographic communication, sensory interconnection, intelligent interaction, communication perception, inclusive intelligence, digital twin, global coverage.
Among them, communication perception can give users more service capabilities beyond communication, such as imaging, environmental reconstruction, precise positioning, etc.; Pratt & Whitney Intelligence makes each device an intelligent body, which can not only support high-speed data transmission, but also Realize the collaboration and learning of different types of equipment.
Huang Yuhong, a member of the expert group of the promotion group and vice president of China Mobile Research Institute, said that in order to meet the performance requirements of new 6G business scenarios, the white paper combed and analyzed ten potential key technology directions that are currently widely concerned by the industry.
Among them, the enhanced wireless air interface technology can further improve the performance of spectrum efficiency, peak rate, positioning accuracy, etc.; the new physical dimension wireless transmission technology can improve network transmission rate, spectrum efficiency and system capacity; deterministic network can be used for industrial manufacturing, The Internet of Vehicles, smart grid, and other application scenarios that require high latency, provide deterministic network guarantee capabilities; satellite-ground integration networking technology can realize the deep integration of space-based, space-based, and ground-based networks, supporting any place and time, Provide unified access and information services.
"6G technological innovation will become the commanding height and an important starting point of the communications industry. From network virtualization to network intelligence, this is not only an extension and improvement of existing technologies, but also an epoch-making network architecture revolution." Tong Wen said .
In addition, from the perspective of building a healthy global industrial ecosystem, the white paper expounds the views of the promotion group on some key issues in the development of 6G, and proposes that the successful commercial use of 5G, especially the wide application in vertical industries, will lay a good foundation for the development of 6G. .
The relevant person in charge of ZTE believes that although 6G will expand to higher frequency bands, based on objective judgments of technology, low-frequency spectrum is still a strategic resource for 6G development. Millimeter waves will play a more important role in the 6G era, while terahertz, etc. The higher frequency band is focused on meeting the needs of specific short-distance and large-capacity scenarios.
Full-area broadband mobile communications should be based on basic and complementary configuration modes under realistic business conditions.
In other words, the 6G network will still be based on the ground cellular network, and non-terrestrial communications such as satellites, drones, and aerial platforms will play a complementary role in achieving integrated seamless coverage of space, space and ground.
"The release of the white paper will provide important guidance for the global 6G development. In the follow-up, we will further increase the application of basic research, and work together with domestic and foreign industries to realize the beautiful vision of 6G." Huang Yuhong said.
