Visitors visited the 31st China International Information and Communication Exhibition. Photographed by Du Jianpo (Zhongjing Vision) at a news conference held by the State Council Information Office a few days ago, Zhao Zhiguo, chief engineer of the Ministry of Industry and Information Technology, introduced that he would adhere to the innovation leadership and promote 5G evolution and 6G technology research and development. Continuously evolving and upgrading towards enhanced 5G, supporting technological product breakthroughs such as 5G R18 base stations and 5G new terminals, and continuously supporting new features and services of 5G. Vigorously promote 6G technology research, conduct technological experiments, deepen exchanges and cooperation, and accelerate 6G innovation and development. We need to strengthen the research and development of 5G enhancement technology, accelerate the maturity of technologies and industries such as millimeter wave, lightweight modules, and high-precision positioning, and actively explore the potential key technology research and development of 6G, "Zhao Zhiguo said. Recently, the International Telecommunication Union completed the "IMT Framework and Overall Objective Proposal for 2030 and Future Development" as scheduled, proposing typical scenarios and capability indicator systems for 6G. It is believed that 6G will further enhance and expand on the basis of the three typical scenarios of 5G. 6G is a unified network that connects the virtual and real spaces of ubiquitous intelligent connections, and will promote the interconnection of all things towards the intelligent connection of all things. Zhang Li, President of the China Institute of Electronic Information Industry Development, believes that from the perspective of network access methods, 6G will include diversified access networks. From the perspective of network coverage, under the 6G vision, an integrated network of "air sky sea ground" will be built across regions, airspace, and sea areas, achieving truly seamless global coverage. From the perspective of network performance indicators, 6G will greatly improve in transmission rate, end-to-end delay, reliability, connection Number density, Spectral efficiency, network energy efficiency and other aspects, so as to meet the diversified network needs of various vertical industries. From the perspective of network intelligence, under the 6G vision, the network and users will be unified as a whole. While artificial intelligence empowers the 6G network, it is more important to deeply explore users' intelligence needs and improve user experience. Zhao Gang, President of Saizhi Industry Research Institute, stated that the Ministry of Industry and Information Technology emphasizes accelerating the development of 6G innovation, aiming to seize the commanding heights of future information and communication technology innovation and comprehensively layout the future 6G industry track. Since 2018, China has started Prospective cohort study and layout of 6G technology research and development. At present, the level of technology research and development is in the first echelon in the world. China leads the United States in the number of patents in the field of 6G technology, but there are still shortcomings in research and development fields such as 6G chips and satellite communication. What potential key technologies for 6G should be actively explored? Zhao Gang said that the first is to accelerate the development of technologies such as terahertz communication chips and explore the application of new semiconductor materials in terahertz chips. The second is to develop base stations and terminal devices for 6G mobile communication, develop broadband satellite ground communication, and load key 6G technologies such as ultra large antennas, intelligent metasurfaces, and communication perception fusion. Third, research and development of 6G+applications. 6G is a new generation mobile communication network integrated with communication, perception, computing, artificial intelligence, Big data, and security, which can meet the needs of immersive, intelligent, and global business and application scenarios. New applications such as 6G+automatic driving, intelligent manufacturing, Metaverse, and generative artificial intelligence need to be developed. Currently, China's 5G technology is at a leading level globally. According to data from the Ministry of Industry and Information Technology, as of June
