6G will be commercialized in 2030. In the future, 6G will expand communication space, realize the integration of ground and satellite communication, and realize the integration of air, land and sea. Compared with 5G, the communication index will be increased by 10- 100 times, and 6G will be commercialized in 2030.
6G will be commercialized in 2030. From March 22nd to 24th, Industry-University-Research, represented by the mobile communication industry, held the 2nd Global 6G Technology Conference, which became an important forum for the global 6G development.
Wu Jiangxing, an academician of China Academy of Engineering, pointed out that as an important supporting technology of intelligent network infrastructure after 2030, the traditional path of pursuing single technical indicators such as coverage, bandwidth and delay is no longer applicable.
6G must explore and develop a new paradigm of multi-objective sustainable and coordinated development such as technical performance, cost input, energy consumption, safety, reliability and sustainable efficiency.
It is reported that 6G is moving from demand to standard according to the established pace. It is widely predicted in the industry that 6G will be listed around 2030.
For 6G, Hong Wei, a professor at the School of Information Science and Engineering of Southeast University, believes that the most revolutionary progress will be the integration of LEO satellite network and ground 5g back network.
For the first time, mankind will realize the full coverage of the wireless communication network on the whole earth surface, near-earth space and even part of outer space, and truly realize the ubiquitous information interconnection.
Xiang, chief scientist of ZTE, also said that satellite communication is an important supplement to terrestrial networks. It has the advantage of cost performance in sparse scenes and provides universal services, but it can't replace the ground network.
In densely populated areas, its production capacity is far from meeting the requirements. In the future, we hope that the key technologies of space-based network and ground network can be integrated and coordinated in a large technical system.
According to the previous prediction, the network speed of 6G can reach 1000gbps, and the delay is less than 100US (that is, 0. 1ms), which is 50 times faster than that of 5g network and only one tenth of the delay. It is far superior to 5g in peak rate, time delay, traffic density, connection density, mobility, spectrum efficiency and positioning ability.
6G will be commercialized in 2030. With the acceleration of the construction of 5G network, related applications began to blossom everywhere, reaching tens of millions of industries. According to the development rhythm of "using one generation, building one generation, researching one generation" in the mobile communication industry, the global industry has begun to explore and study the next generation of mobile communication (6G).
"China is expected to achieve 6G commercialization around 2030." On March 22nd, the 2nd Global 6G Technology Conference was officially held. Zhang Ping, an academician of China Academy of Engineering and a professor at Beijing University of Posts and Telecommunications, predicted at the 6G Vision and Technology Demand Forum.
6G is on the road
4G changes life, 5G changes society and 6G changes the world.
"6G will move towards a ubiquitous minimalist network with full human-computer connection, combination of reality and reality, and emergence of wisdom." Zhang Ping pointed out that "spirit" refers to the network of the spirit world, that is, China's version of the meta-universe. 6G and minimalist wireless networks will strongly support digital twinning, which will further provide continuous autonomous endogenous optimization for the evolution of minimalist networks.
Zhang Ping explained that before 4G, mobile communication pursued communication speed, and 5G put forward requirements for communication, reliability and time delay. In the future, 6G will expand communication space, realize the integration of ground and satellite communication, and integrate air, land and sea. Compared with 5G, the communication index will be increased by 10- 100 times, and centimeter-level high-precision positioning will be realized, leading to the emergence of man-machine, material and spirit.
In the scene, Zhang Ping thinks that 6G will realize digital twins and ubiquitous wisdom. Future application scenarios include holographic interaction, virtual travel, immersive social interaction and so on. For 6G potential key technologies, on the one hand, it is the enhancement of traditional technologies, such as terahertz and visible light. On the other hand, it is innovative technologies, such as quantum communication and AI empowerment.
Zhang Ping introduced that at present, major countries and regions in the world have launched 6G research, and accelerated the research and development of 6G innovative technologies by increasing capital investment and arranging scientific research projects.
The EU has put forward a relatively clear planning roadmap and completed the 6G Industry-University-Research Framework Project in the third quarter of 2020; Finland released the 6G white paper "Drivers and Main Research Challenges of 6G Ubiquitous Wireless Intelligence", and systematically looked forward to the 6G vision and technology application; The Korean government has put forward the goal of "leading the commercialization of 6G" and plans to realize the first commercial 6G in the world in 2028;
Japan released the B5G promotion strategic goal to complete the research on 6G basic technology in 2025 and commercialize it in 2030; The United States also started the research of 6G from 20 18. The previous research includes the research of 6G chip, and the research and practice of integrated communication of air, space, sea and land, especially satellite Internet communication.
"China attaches great importance to the development of 6G. In the Tenth Five-Year Plan, it is clearly proposed to' prospectively lay out the 6G network technology reserve'. The National 6G Technology R&D Promotion Working Group, the General Expert Group and the IMT2030(6G) Promotion Group have been established successively to solidly promote all aspects of 6G work and make positive progress. " Zhang Ping said.
6G changes the world
Facing 2030 and the future, 6G network will help to realize the deep integration of the real physical world and the virtual digital world, and build a brand-new world in which everything is connected with digital twins.
"6 G' digital twins, ubiquitous wisdom' is everyone's beautiful vision." Cui, director of the Green Communication Research Center of China Mobile Communication Research Institute, believes that the typical use cases of 6G include holographic interaction, digital twins, synaesthesia interconnection, intelligent transportation, intelligent production and meta-universe, which put forward higher requirements for 6G networks: First, extreme capacity; Second, the software-defined distributed network; Third, global coverage; Fourth, the ubiquitous wisdom; Fifth, endogenous security.
"For operators, we hope to realize a network with digital twin operation, zero contact and automatic operation and maintenance, which can improve efficiency and reduce costs, and can' survive and evolve'." Cui said:
Penny Peng, a senior engineer of radio frequency system in ZTE Wireless Research Institute, also believes that new service modes will be born in the 6G era, such as the experience of immersive cloud XR, holographic communication, new digital twin formats, etc., which will further extend to the Internet of AI and perceive the Internet, and enter the 6G era of all things intelligence.
"The vision and capability requirements of 6G push the industry to further develop air interface resources. For example, tap new spectrum resources and move towards higher millimeter wave and terahertz frequency bands. " Penny Peng said.
According to Wang Jun, a technical expert in Huawei Wireless Technology Laboratory, 6G will further develop its capabilities beyond communication, and expand two application scenarios, namely artificial intelligence and communication perception, based on the three application scenarios of 5G.
How does 6G integrate the physical world with the digital world? Wang Jun pointed out that from the physical world to the digital world is a typical downlink channel, and AI capabilities such as deep learning, machine learning and big data analysis are transmitted to users through immersive experiences such as AR/VR; From the physical world to the digital world, it is a typical ascending channel, which mainly uses full scene perception and big data acquisition for machine learning to improve the perfection and ability of the digital world model.
"In this process, 6G will integrate connectivity, perception and artificial intelligence capabilities and become a key bridge." Wang Jun said.
Explore the technical path
At present, IMT-2030(6G) vision research has formed * * * knowledge, including: immersive cloud XR, holographic communication, sensor interconnection, intelligent interaction, communication perception, digital twins, pervasive intelligence, global coverage and other new applications.
In order to meet the richer business applications and extreme performance requirements of the future 6G, it is necessary to achieve breakthroughs in key core technologies on the basis of exploring new network architectures. At present, the global industry is still exploring the key technologies of 6G, and puts forward some potential key technology directions and new network technologies.
Wei Xu, a professor at Southeast University, believes that the future development trend of 6G technology is to cover more in more frequency bands, wider bandwidth and deeper dimensions, and finally realize faster and more stable transmission, and integrate more carbonized and smarter intelligent networks.
"China Telecom believes that endogenous expansion and green ubiquity are the overall vision of 6G networks, thus creating a new engine for harmonious development." Wang Qingyang, director of the Institute of Mobile Communication of China Institute of Telecommunications, said that the future IMT2030 will be an endogenous intelligence and security, an expanded perception and experience, a new system with intelligent interconnection of human, machine and things, and an engine for the harmonious development of human society and natural environment.
"Therefore, the innovation and development of 6G technology should take green energy saving as the basic principle, improve system energy efficiency and implement ecological operation; At the same time, we must also consider how 6G technology can empower thousands of industries to help the industry deepen digital transformation and achieve green and low-carbon development. " Wang Qingyang said.
Mao Junfa, an academician of China Academy of Sciences and a professor at Shanghai Jiaotong University, pointed out that 6G should improve the quality of 5G in three dimensions, namely, more connections, wider coverage and wider bandwidth. The first two can achieve the defect of insufficient connection and coverage by supplementing the number of base stations. But for the large bandwidth requirement of 6G, only millimeter wave terahertz technology can achieve the goal.
Experts attending the meeting also said at the 6G Millimeter Wave and Terahertz Technology Forum that although the development of 6G Millimeter Wave and Terahertz technology faces many technical challenges at this stage, with the continuous breakthrough of related technologies and the continuous development of high-frequency device industry, Millimeter Wave and Terahertz will be integrated with other low-band networks by virtue of their rich frequency bandwidth resources and other natural advantages, and will be widely used in multi-dimensional and multi-scale communication scenarios as an important supporting technology for future 6G communication.
"6G network must become an intelligent, distributed and extensible program platform to meet the growing application needs." Intel Labs and IEEE Fellow Rath Vanity Mbi pointed out that 5G and AI are changing the wireless network and promoting the development of wireless distributed intelligence. 6G networks need to seamlessly integrate communication, technology and AI to achieve a unified quality of experience (QoE). "At present, the research of intelligent network distributed integration technology needs interdisciplinary academic research and collaborative design."
In 2030, 6G will realize the development rhythm of "using a generation, building a generation and researching a generation". All walks of life in Industry-University-Research, represented by the mobile communication industry, have gradually sorted out more clear and targeted promotion ideas from the initial imagination, discussion and research on 6G.
The second "Global 6G Technology Conference" held from March 22nd to March 24th will become an important forum for the global 6G development.
Wu Jiangxing, an academician of China Academy of Engineering, pointed out that as an important supporting technology of intelligent networking infrastructure after 2030, the traditional road of pursuing single technical indicators such as coverage, bandwidth and time delay is no longer suitable. 6G must explore and open up a new paradigm of multi-objective sustainable and coordinated development such as technical performance, cost input, energy consumption, safety, reliability, sustainability and high efficiency.
6G will move towards an intelligent and simple network with man-machine connection.
Zhang Ping, an academician of China Academy of Engineering and a professor at Beijing University of Posts and Telecommunications, delivered a speech at the roundtable forum on "6G Vision and Technical Requirements" of the global 6G technology conference held yesterday.
Zhang Ping said that from 1G-4G, it is mainly the communication between people, which is a linear increase in the communication rate; 5G is a surface improvement, which realizes the communication between people, people and machines, and machines and machines; 6G will expand communication space, integrate ground and satellite communications, and realize the integration of "land, sea and air".
"4G changes life, 5G changes society and 6G changes the world." Zhang Ping said that compared with 5G, the communication index of 6G will be increased by 10- 100 times, and it will also achieve centimeter-level high-precision positioning.
6G will realize digital twins and ubiquitous wisdom. Future application scenarios include holographic interaction, virtual travel, immersive social interaction and so on.
For 6G's potential key technologies, Zhang Ping believes that on the one hand, it is the enhancement of traditional technologies, such as terahertz and visible light; On the other hand, it is innovative technologies, such as quantum communication and AI empowerment.
"6G will move towards an intelligent and simple network with man-machine connection." Finally, Zhang Ping concluded that the spirit in people's cleverness refers to the spiritual world network, which is China's version of the meta-universe.
When satellite networks join, it becomes a common expectation.
From demand to standard, 6G is progressing at the established pace. The industry generally predicts that 6G will be commercialized around 2030.
Biqi, chief expert of China Telecom, said: "The wish is good. How to determine the vision with real commercial value and accelerate the research and development of related key technologies in order to put them into actual deployment during the 6G period is an important task of scientific research in the next few years. "
For 6G, Hong Wei, a professor at the School of Information Science and Engineering of Southeast University, believes that the most revolutionary progress will be the integration of low and medium orbit satellite networks and terrestrial 5G networks. For the first time, mankind will realize the full coverage of the whole earth surface, near-earth space and even part of outer space through wireless communication network, thus truly realizing the ubiquitous information interconnection.
For the expectation of 6G wide coverage, Musk's LEO satellite "Star Chain" has played a certain stimulating role.
"At present, Musk's' Star Chain' receives and transmits signals through satellite pots, and the target user group is very different from mobile communication." Biqi pointed out that whether 6G can break through the problems of link loss and business model, and connect the satellite chain to the mobile phone without satellite dish antenna during 6G, and how many 6G users are willing to bear the cost of satellite service is still a great challenge.
Xiang, chief scientist of ZTE, also said: "Satellite communication is an important supplement to terrestrial networks. It has the advantage of cost performance in sparse scenes and provides universal services, but it can't replace the ground network. In dense areas, its capacity is far from meeting the requirements. In the future, we hope that space-based networks will be integrated and coordinated with ground networks in a large technical system. "
6G competition is surging.
The R&D work kick-off meeting will officially start the 6G R&D work. The 14th Five-Year Plan for the Development of Digital Economy released this year clearly proposes to lay out the sixth generation mobile communication (6G) network technology reserves in a forward-looking way, increase the support for 6G technology research and development, and actively participate in promoting 6G international standardization.
Internationally, in February, 2020, the International Telecommunication Union held the 34th ITU Working Group Meeting, officially launched the research work of 6G, and defined the timetable for the preliminary research of 6G of the International Telecommunication Union before the end of 2023.
Apple, Google, Microsoft and other American 1 1 companies announced the establishment of the 6G Alliance in 2020; The EU launched a three-year 6G basic technology research project.
Japan's official-civilian alliance is preparing to submit the draft 6G international standard to the international conference in June. Japan hopes to gain more dominance in the development of 6G network technology and have more right to speak in the formulation of technical specifications, so as to promote the development of technology in a dominant position. * * * puts forward technical requirements for future 6G wireless communication.
In addition, Britain, Finland and South Korea have also developed 6G technology, hoping to gain a favorable position in the global competition of 6G technology standards in the future.
Xia Han, chief engineer of the Ministry of Industry and Information Technology, once said that in the future, 6G services will present new development trends such as immersion, intelligence and globalization, and form an immersive cloud XR, holographic communication, sensor interconnection, intelligent interaction, communication perception, inclusive intelligence, digital pairing, global coverage and other business applications, which will eventually help human society realize the beautiful vision of "Internet of Everything, digital pairing".
