With the rapid development of 5G communication technology, the prospect of next-generation mobile communication technology has been put on the agenda. Recently, the "Global 6G Technology Conference" was held in the form of online. The next generation of mobile communication technology represented by 6G is the focus of attention and research hotspots of all parties, traditional communication technology powers, the world's leading operators and technology companies, and related research institutions have joined the ranks of 6G research and development, and 6G exploration and research and development has entered an accelerated period.
White papers related to 6G technology were released
The Future Mobile Communications Forum released 13 white papers at the 2nd Global 6G Technology Conference, defining 6G-related technical concepts, indicators and capability extensions with unprecedented efforts in the industry.
Among them, the overall white paper "6G Network 2.0 under ICDT Convergence" and 9 special white papers were released on the 6G topic, covering digital twins, next-generation protocol stack 4.0, terahertz, multiple access, intelligent hypersurface, zero power consumption, quantum information, terminal friendliness, intelligent rail transit; "5G/6G millimeter wave test technology" white paper was released in the millimeter wave aspect; "5G millimeter wave enabled 8K video production" and "5G millimeter wave enabled 8K video production" and "5G millimeter wave enabled 8K video production" and "5G millimeter wave enabled 8K video production" and "mobile ultra-high definition video" were released in terms of mobile ultra-high definition video. Future-proof mobile broadband audio and video transmission protocols— the status quo and challenges" white paper.
It is understood that this year's Global 6G Technology Conference brings together the global 6G technology research force and comprehensively demonstrates the innovative ideas and latest achievements of 6G technology research and development.
Global collaboration has stepped up the layout of 6G research and development
With the large-scale commercial use of 5G networks, the strategic layout of global R&D for 6G research and development has been fully launched, and major countries and regions in the world have launched 6G research, using measures such as increasing capital investment and laying out scientific research projects to accelerate the research and development of 6G innovative technologies.
After proposing a relatively clear planning roadmap, the European Union announced a grant of 240 million euros in December to launch the first large-scale 6G research and innovation plan; the South Korean government, which plans to "achieve the world's first 6G commercial use in 2028", announced in June last year that it would invest 220 billion won to develop and standardize 6G core technologies by 2025; Japan has also formed a government-private alliance and plans to submit a draft 6G international standard to the international conference in June this year; and the U.S. Telecommunications Industry Association has established a "6G alliance." ", the coordinating industry technology giants to promote the United States in the next communications development cycle (10 years), to achieve a global leading position in the field of 6G and even 7G.
In November 2019, the 6G technology research and development promotion working group and the overall expert group were established, and the mainland 6G technology research and development work was officially launched. Today, 6G has been written into the national top-level documents. In January this year, the State Council issued the "14th Five-Year Plan for the Development of the Digital Economy", which mentioned that the forward-looking layout of 6G network technology reserves, increase support for 6G technology research and development, and actively participate in promoting 6G international standardization. Xiao Yaqing, minister of the Ministry of Industry and Information Technology, also said during the two sessions this year, "In the process of 5G development, it is necessary for all walks of life to form a synergy and mutual integration, and at the same time consider the deployment of technology research in the direction of 6G evolution." ”
The next 3 to 5 years is a critical window period
Towards 2030, what is the driving force for the continuous evolution of the mobile communications industry? What are the basic features that will be presented? Facing the new paradigm of 6G, what new opportunities and challenges will the wireless connectivity industry usher in?
Experts at the Global 6G Technology Conference generally predict that 6G will start corresponding standardization work around 2025 and achieve commercialization around 2030. There is a consensus in the industry that the next 3-5 years will become a window period for potential key technologies of 6G.
Xiang Libin, vice minister of science and technology, said: "6G technology academic research towards the industrial vision needs a process, and 2022 is a key year for this process. Today's discussion of new concepts, new technologies, and new ideas about 6G is related to the face of tomorrow's mobile communications, which will change the face of human society. ”
Although the 6G standard is driven by technology, the final use will depend on the business, that is, the demand side drive. Liang Zhenpeng, a veteran industrial economy observer, said that the rollout of communication technology still needs the coordination of the whole industry chain, and cannot be rushed to achieve success, and in the next 3-5 years, China's 5G network can penetrate into third- and fourth-tier cities and even rural townships, in order to lay a solid foundation for 6G development.
