What is 6G? Eight business application scenarios emerge

Original title: What about 6G? Eight business application scenarios surfaced

At present, a new round of technological revolution and industrial transformation are advancing by leaps and bounds. With the large-scale commercial deployment of 5G, the global industry has begun to explore the next generation of mobile communications (6G). Yesterday, the IMT-2030 (6G) Promotion Group (hereinafter referred to as the “Promotion Group”) officially released the “6G Overall Vision and Potential Key Technology White Paper” (hereinafter referred to as the “White Paper”). As a staged achievement of the promotion group, the white paper covers the overall vision, eight business application scenarios, ten potential key technologies, etc., and expounds some thoughts on the development of 6G.

Facing 2030 and the future, human society will enter the era of intelligence. Social services will be balanced and high-end, social governance will be scientific and precise, and social development will be green and energy-saving will become the development trend of the future society. On the basis of 5G, 6G will further expand from serving people, people and things to supporting the efficient interconnection of intelligent bodies. It will realize the transition from the interconnection of all things to the intelligent connection of all things, and become a link between the real physical world and the virtual digital world. Continue to improve people’s quality of life, promote the transformation and upgrading of social production methods, and contribute to the ultimate goal of sustainable development of human society, and ultimately help human society realize the vision of “All Things Connected, Digital Twins”.

　　Presenting the development trend of immersion, intelligence, and globalization

The white paper points out that driven by three factors, the future 6G business will present new development trends such as immersion, intelligence, and globalization, covering immersive cloud XR, holographic communication, sensory interconnection, intelligent interaction, communication perception, and inclusive intelligence. , Digital twin, global coverage and other eight business application scenarios.

The first is the trend of immersion. Potential businesses represented by immersive cloud XR, holographic communication, sensory interconnection, and smart interaction will focus on human experience, from 2D to 3D, from audio and video to multi-dimensional senses, and from perceptual immersion. When it comes to cognitive communication, through the blending of virtual reality and real-time feedback, it brings people a brand new experience that is immersive and indivisible between virtual and reality, and establishes a communication bridge between the digital world and the physical world.

The second is the trend of intelligence. Potential services represented by inclusive intelligence, communication perception, and digital twins will produce a wide range of new smart terminals with self-learning capabilities. These smart bodies and 6G networks can better communicate through wireless signals. Perceive and monitor the environment, tap communication capabilities, and enhance user experience. In the future, it is even possible to model the physical world and realize the mirror model of the physical world in the digital world, and realize the intelligent interaction between the digital world and the physical world through methods such as simulation, verification, prediction, and control.

The third is the globalization trend. In the future, through the integration of terrestrial cellular networks with satellites, high-altitude platforms, unmanned aerial vehicles and other space networks, an integrated three-dimensional network of space, space and ground with global coverage will be built. Global coverage will provide broadband access to remote areas, aircraft, cars, ships, etc., and wide-area Internet of Things access to areas without ground network coverage in the world, providing high-precision positioning, high-precision navigation, precision agriculture, emergency rescue, etc. service.

　　Propose ten potential key technologies

In order to meet the richer business applications and extreme performance requirements of 6G in the future, the white paper puts forward ten potential key technology directions for 6G that are currently widely concerned by the industry, including endogenous intelligent new air interface and new network architecture, enhanced wireless air interface technology, new Physical dimension wireless transmission technology, new spectrum use technology, communication and perception integration technology and other new wireless technologies, distributed network architecture, computing power perception network, deterministic network, satellite-ground integration networking, network endogenous security and other new network technologies . The application of the above and other potential key technologies in 6G will greatly improve network performance, meet the needs of future social development of new services and new scenarios, serve the intelligent society and life, and help realize the 6G vision of “All Things Connected, Digital Twins”.

The white paper expounds the views of the promotion group on four key issues in the development of 6G. The first is about the relationship between 5G and 6G development. It is proposed that 6G will transition from the Internet of Everything to the Intelligent Connection of Everything on the basis of 5G. The successful commercial use of 5G, especially its wide application in vertical industries, will lay a good foundation for the development of 6G. The second is about 6G spectrum resources. It is proposed that 6G will be extended to higher frequency bands, and the low, medium and high full spectrum resources will be used efficiently. Among them, low-frequency spectrum will still be a strategic resource for 6G development, millimeter waves will play a more important role in the 6G era, and higher frequency bands such as terahertz will focus on meeting the short-distance and large-capacity requirements of specific scenarios. The third is about the evolution of 6G intelligence. It is proposed that the wisdom and endogenousness of all things will become an important feature of 6G. The deep integration of artificial intelligence and communication technology will lead to all-round innovation in network information technology. The fourth is about the relationship between satellite and other non-terrestrial communications and cellular networks. It is proposed that the future 6G network will still be based on terrestrial cellular networks. Satellites, drones, air platforms and other non-terrestrial communications will be integrated in the space, space and ground Seam coverage plays an important role.

　　China TelecomThe institute has been deeply involved in the research work of the promotion group since 2019, and has taken the lead in the development of the ITU-T international standard “Requirements for Interactive Immersive Services” (H.IIS-reqts) and “6G network architecture and key technologies” And other national key special research work, while actively promoting the international standard work of 5G enhancement technology and its landing in 5G vertical applications, laying the foundation for 6G business and key technology research.China TelecomThe Institute will adhere to the spirit of “keeping integrity, innovation, openness and integration”, and under the guidance of the IMT-2030 (6G) promotion group, unite forces from all walks of life to carry out “production, study, research and application” technological breakthroughs, and realize 6G key technological breakthroughs as soon as possible.Comprehensive
