6G footsteps are approaching. Recently, at the 2024 Global 6G Technology Conference hosted by the Future Mobile Communications Forum and the Zijinshan Laboratory, guided by the National 6G Technology Research and Development Promotion Working Group and the Overall Expert Group, three co chairs of the Global Mobile Communications Standard Setting Organization 3GPP (Third Generation Partner Program) shared the 3GPP 6G standard schedule: in September 2024, a 6G business requirement study will be launched; Starting 6G technology pre research in June 2025; Starting the development of 6G standards in the first half of 2027; In 2029, the basic 6G version standard, namely the Rel-21 version standard, will be completed. 2024 is a critical window for the selection of 6G technologies, and the 6G standard will also be launched this year. According to the development rhythm of the mobile communication industry of "using one generation, building one generation, and researching and developing one generation", the 6G technology roadmap and scenario requirements are increasingly being discussed and clarified by various parties. The deep integration and collaborative innovation of multiple technologies, as a new generation of digital information infrastructure, 6G will become a bridge connecting the physical world and the digital world, helping to achieve the leap from the Internet of Things to the Internet of Things. According to Yi Zhiling, Chief Scientist of China Mobile Research Institute, compared to 5G, 6G networks are expected to significantly improve in transmission speed, latency, and other aspects: the peak speed will reach 100Gbps, which is 10 times higher than 5G; The latency will decrease to 0.1 milliseconds, only one tenth of 5G. In addition, the 6G user experience will also be significantly improved compared to 5G. At present, major economies around the world are accelerating the promotion of 6G research and development, and governments and enterprises around the world are investing heavily in 6G technology research. At present, 6G research is in the stage of defining requirements and breaking through key technologies in the early stage of standardization. Yi Zhiling emphasized that the evolution of mobile communication technology is not only a transformation of wireless air interface technology, but also a deep integration and collaborative innovation of various technologies such as communication technology, information technology, and data technology. In her view, 6G is a new generation of mobile information network that deeply integrates sensing, computing, and intelligence, with full coverage of space, space, and space. Specifically, to achieve an integrated wireless network of sensing, intelligence, computing power, and data processing, it is necessary to increase the capabilities of perception, intelligence, computing power, and data processing; To achieve full coverage of space, space, and space, it is necessary to focus on low orbit satellites and consider their better matching with ground cellular mobile communication networks at the business, network, or air interface levels. She also admitted that in the process of any new technology from start-up to large-scale deployment, problems such as high cost and high energy consumption are difficult to avoid, and this is also true in the 6G deployment process. In addition, on the consumer end, although 5G's spectrum efficiency and unit energy efficiency are far superior to 4G, ordinary users find it difficult to perceive this advantage; The exponential growth of user traffic has not been reflected in the ARPU (average revenue per user) value of operators. Wu Hequan, academician of the CAE Member, pointed out that the 5G dividend received by operators was not as expected. Drawing on the experience of 5G, 6G needs to be more diversified and personalized to meet the differentiated preferences of different application scenarios for terminals, network speed, spectrum, intelligence, security, and latency. With the clarification of the 3GPP 6G standard schedule, the industry's attention to 6G has reached an unprecedented level, taking into account green, performance, and other requirements for implementation
