On June 6, MWC Shanghai with the theme of "Time is Waiting" officially opened. At the "28G Vision and Key Driving Forces" conference forum held in the afternoon, Dr. Huang Ying, Vice President of Lenovo Group and Head of the 6G Lab of Lenovo Research Institute, delivered a speech entitled "Create brilliance together:Thoughts and Prospect on 5G Technology and Applications". He believes that under the technological change, 6G, as a next-generation communication technology, has larger connections, lower latency and faster speedspeed, greater intelligence and security, scalability and converged awareness, will bring disruptive changes to the world.

Under the wave of technological change, technological breakthroughs in the field of wireless communication are constantly staged. In June 2022, the International Telecommunication Union Radio Agency completed the first technical research report for 6G, marking the initial global consensus on the direction of 6G. The next 6-3 years will be the key window period for 5G layout, Lenovo, as a typical representative of "dual-real enterprise", will rely on the new "device-edge-cloud-network-intelligence" new IT technology architecture to continue to promote technological breakthroughs and application innovation in the field of communications, making the world more intelligent, convenient and efficient.

Full spectrum, full coverage, full application, strong intelligence, 6G brings disruptive changes to the world

At present, the degree of digitalization of society is deepening, and the development of communication technology is advancing by leaps and bounds. The 5G era has entered the "second half", and the global industry has opened the next stage of research and exploration, and 6G is the representative of the next generation of mobile communication technology. If 5G opens the door to the Internet of Everything, 6G is expected to evolve into a fully connected platform. Dr. Huang Ying said that compared with previous mobile communication technologies, 6G has greater speed, lower latency, greater connection, higher intelligence, and communication and perception fusion capabilities, and AI and computing power will be everywhere.

The first is faster network speed, 6 G can effectively play the terahertz band (100GHz~10THz) communication potential, its peak rate can reach 1000Gbps, users experience the speed in daily lifeIt will be greater than 1Gbps and downloading a movie in a second will not be a problem, while in terms of network capacity, 6 G will be 51 times more than 00G. Secondly, network latency has always been the key to breakthroughs in communication technology, and future-oriented 6G technology, the delay can be as low as 0.1 milliseconds, and the reliability is greatly increased; Through technologies such as space multiplexing and dynamic spectrum sharing, 6G networks have extremely high connectivity and extremely low power consumption, allowing them to achieve large-scale machine-type communication in industrial scenarios. In addition, through the commercialization of technologies such as global satellite communication systems, and through further integration of key technologies such as communication and network virtualization, 6G is expected to solve the problem of multi-type network communication convergence and promote the full coverage of wireless networks. Finally, 6G will efficiently support ubiquitous artificial intelligence and innovate customized intelligent services. Through deep integration with AI, machine learning, etc., 6G extends the "human-machine-thing" connection to the intelligent field and accelerates the upgrading of social intelligence.

Dr. Huang Ying believes that 6G will be a "super channel" for people to connect the virtual and real worlds under fully intelligent applications. Compared with the existing 5G, 6G will lead people into a more ubiquitous and intelligent world, which can effectively promote the intelligent upgrading of people's life and work, and bring users a more diversified, personalized and digital new experience. Including immersive XR experience, holographic communication, sensory interconnection, intelligent interaction, communication perception, inclusive intelligence, digital twin, collaborative robots, etc.

Dr. Huang Ying also proposed the concept of AICT for the first time, namely AI+IT+Communication, AI integrates with IT and communication, completely opening up the three, as an intelligent computing communication network platform, ready for various future applications.

Integrate traditional technology experience with emerging technology advantages and join hands to move towards the 6G era

6G will realize the transition from serving people, people and things to supporting efficient connectivity of intelligent twins, and meet the needs of high-quality economic and social development through intelligent interconnection and collaborative symbiosis between people, machines and things.

Dr. Huang Ying said that in order to achieve these very advanced performance and functions of 6G, it is necessary to give full play to the potential of traditional technologies through evolution and upgrading, and also introduce many emerging technologies into the field of communication technology, including new materials and new processes.

In terms of tapping the advantages of traditional technologies, Dr. Huang Ying pointed out that while 5G provides high speed, low latency, large connections and other characteristics, it also faces problems such as overcommitment, over-configuration, and excessive cost, resulting in the commercial application of 5G has not yet met expectations.

He believes that several enlightenments can be drawn from the development experience of 5G. The first is to understand the real cost-effectiveness from the user's perspective and bring real value to customers, such as intelligent manufacturing, autonomous driving, games, etc.; The second is cooperation between the entire ecosystem, including standards bodies, equipment manufacturers, operators, consumers, industry users, etc.; In addition, the industry should build a flexible and adaptable network to meet the customization of different needs; Finally, it is essential to establish a scalable framework that is forward-compatible and provides room for future growth.

At the same time, Dr. Huang Ying believes that in order to achieve these goals, 6G needs to explore new technologies such as new network architecture, new spectrum resources, new electromagnetic modes, new material equipment, and new duplex modes, while further enhancing the comprehensive capabilities of native artificial intelligence, computing power, perception, and trust, and improving the capabilities of waveform, multiple access, modulation, channel coding, etcTraditional areas continue to innovate.

Lenovo actively carries out technology accumulation and cutting-edge exploration in the field of communications. In the 5G field, Lenovo is committed to exploring 5G wireless protocols and algorithms, 5G testing and certification, and 5G network architecture, generating high-performance algorithms and wireless transmission systems, participating in the formulation of 5G international standards, and creating a competitive 5G standard-essential patent pool. At present, the number of Lenovo 5G SEP applications has exceeded 2400. In the 6G field, Lenovo is conducting research and prototype verification of key 6G technologies, focusing on key technologies such as terahertz, synaesthesia integration, semantic communication, intelligent endogenous networks and reconfigurable intelligent surfaces.

The industry generally believes that 6G will begin to be commercially landed in 2030. In the future, Lenovo will continue to drive technological change in the communications field with its new I't full-stack technology capabilities, and further promote the gradual implementation of new technologies in various scenarios such as production lines, factory parks, ports, transportation, and smart city services, empowering thousands of industries and accelerating the integration of data and realityPromote the era of intelligent interconnection of all things with new IT.
