The commercial time of each generation of mobile communication is the time of research and development of the new generation of mobile communication. In the past three years since the licensing, 5g in China has entered a critical period of large-scale application, and 5g commercial has entered a virtuous cycle. Meanwhile, the continuous innovation and evolution of 5g have also laid a solid foundation for the vision and technical direction of 6G. The data of 5g-a evolution shows that more than 200 operators in the world have deployed 5g commercial networks. It is expected that by the end of 2022, the number of global 5g connections will reach about 1.2 billion. As of June this year, China has completed and opened 1.854 million 5g base stations, covering all prefectures, cities, county towns and 92% of townships and towns in the country. The number of 5g mobile users reached 455 million, and the number of 5g base stations and users accounted for more than 60% of the world. At the application level, 5g typical scenarios have been integrated into 40 of the 97 categories of the national economy, and large-scale applications have been realized in mines, ports and other fields. While achieving remarkable results, 5g continues to evolve. At the 2022 World 5g conference, Wu Hequan, an academician of the Chinese Academy of engineering, said that 5g advanced, as an enhanced evolution of the subsequent stage of 5g, is committed to improving personal real-time interaction experience, enhancing the ability of cellular Internet of things, and constantly exploring new scenarios such as uplink ultra wideband, real-time broadband interaction and perceptual positioning. The low-carbon base station has also made gratifying progress. In terms of standards, in June this year, major progress was made in the most critical technical standard field of 5g - 3GPP release 17 standard was announced to be frozen. At present, R & D and innovation oriented to R17 and R18 standards are accelerating, which will provide a technical basis for wider industrial applications. Xu Wei, head of research and development of Qualcomm in China, said that on the basis of the flexible spectrum framework created by release 15, release 16 and release 17 continue to introduce new technologies oriented to the vertical field, such as Internet of vehicles technology, 5g based wireless Internet of things technology, satellite antenna technology, and so on. These technologies have further laid a good foundation for the development of 5g advanced and 6G. The evolution of technology will not be carried out according to the time plan. Once the technology is mature, the industry will spare no effort to advance it. 6G R & D on the road 6G is not a simple upgrade of 5g, but a leap forward. At present, the industry is in the early vision research stage of 6G. Relevant industrial organizations are actively discussing the vision needs of 6G and conducting research on key technologies. 6G will subvert people's understanding of mobile networks. 6G will fully support the digital transformation of the whole society, and realize the intelligent physical world and the digital world. According to the chief expert of China Telecom, the director of the expert committee of China Telecom Research Institute, and IEEE fellow, the 6G vision includes global ubiquity, instantaneous speed, high efficiency and energy saving, certainty and reliability, immersive holography, intelligence and inclusiveness, synaesthesia multidimensional and virtual reality twin. Wang Jun, vice president of Huawei wireless network product line and chief scientist of 6G, said that 6G will develop two key scenarios on the basis of 5g, one is intelligence and the other is perception. Therefore, 6G is not only a platform for all things to connect, but also an integration of general calculation and general sense
