From August 10th to 12th, the 2022 World 5G Conference was held in Harbin City, Heilongjiang Province. It is understood that the World 5G Conference is an important international event in the world's 5G field. Since its first session in Beijing in 2019, it has been successfully held for three sessions.

With the large -scale commercial use of 5G into the fast lane, major countries in the world have begun to force 6G research on the next generation of mobile communication technology. Especially, the United States, Europe, Japan, and South Korea, which are "stimulated" on 5G, are full of energy. They can't wait to "overtake" on 6G to regain the dominance of the global communication field.

At present, the consensus formed by the global technology community and industry is that humans will usher in the 6G era around 2030. However, the 6G in the buds has now appeared to face more intense global competition than the 5G era.

The original title is "The United States, Europe, Japan, and South Korea" Holding the ball "and want to overtake 6G, experts: eat a bite by bite".

The United States, Europe, Japan and South Korea "Holding the group"

In 2020, the United States opened a 6G layout when the 5G was not mature and popularized. According to foreign media reports, some US officials and experts advocate that the United States should give up the catch -up in 5G technology and jump directly to 6G research and development.

In August 2020, the Trump administration officially approved the 6G experiment. Subsequently, the Federal Communications Commission (FCC) decided to open the 95GHz-300GHz (Taihez) frequency band as an experimental spectrum and officially launched 6G technology research and development.

Soon, the US Telecom Industry Solutions Alliance (ATIS) led the establishment of "Next G Alliance" (hereinafter referred to as "NextG League"). , Global promotion of 6G technology and services, but the ultimate goal is undoubtedly established the leadership of the United States in the 6G era.

The founding members of the NEXTG Alliance include ATT, Bell Canada, Ericsson, Facebook, Microsoft, Nokia, Qualcomm, Samsung, Verizon, etc. After that, Cisco, Intel, LG Electronics, Apple, Google, Sharp, DOCOMO and other companies also joined.

From the list of members, it is not difficult to find that the 150 members of the NEXTG Alliance have now joined the NEXTG League, including the major ICT industry giants of the United States, Europe, and South Korea, and important companies in many ecological chains, but they have excluded the participation of Chinese companies. In addition, the NextG League also clearly requested that organizations that are exported, exported or transferred in the entity list of the US Department of Commerce are not qualified to participate in the alliance.

In fact, in recent years, the United States has been continuously strengthening technical cooperation with Europe, Japan, and South Korea through joint research and development and signing large -scale procurement contracts to create a "6G small circle" with allies with allies.

"Eat a bite and take a bite"

But can the United States really bypass 5G development 6G?

"The development of communication technology requires the improvement of technical accumulation and ability of generations. The so -called bypassing 5G to develop 6G is difficult to achieve. Tell reporters.

Xiang Ligang said that the basic situation of the development of mobile communication technology is that the vision of this generation of mobile communication can not be completed until the next generation. The positioning of 6G is the extension and improvement of 5G, not a new technological revolution. "You can understand 6G as 5G+." He said.

For example, the vision of 5G is the interconnection of all things, but there are still many places that need to be perfect at present, and it is likely to need to be completed in the 6G era.

Similar situations are in the era of 1G to 2G, as well as in the 3G to 4G era. 1G to 2G jointly realizes the ability of mobile communication (such as mobile phone calls). 3G to 4G realizes data transmission (such as mobile phone access) while mobile communication, while 5G and 6G are solved by all things.

As early as March 2018, Miao Wei, then Minister of Industry and Information Technology, said that China had started to study 6G. In June 2019, the Ministry of Industry and Information Technology led the establishment of China's IMT-2030 (6G) promotion group, marking the official launch of my country ’s 6G R & D. The promotion group pointed out in the white paper in the "6G General Vision and Potential Key Technology" that China ’s leadership in the 5G field will extend to the 6G field.

In the same year, China Mobile, China Unicom, and China Telecom's three major telecommunications operators also launched 6G related technical research on the outside world. Huawei, ZTE, VIVO, OPPO, Xiaomi and other equipment manufacturers have also opened 6G pre -research work.

Data from the China Institute of Information and Communication show that as of the end of June 2022, my country has built 1.854 million 5G base stations, covering all levels and cities in all towns and towns and towns in all counties and cities and towns. China ’s 5G mobile phone users have more than 450 million households. And it is expected that by the end of this year, the total number of 5G base stations in my country will exceed 2 million. China has built the world's largest 5G network, which also allows us to have the world's largest and technological -leading network infrastructure. After the efforts of all parties in China, the development of all parties in China, according to the 48th "Statistical Report of the China Internet Development Status" released by CNNIC in August 2021, China has become the main applicant of the world's 6G patents. Among the 38,000 6G patent applications around the world, the number of applications in China was about 13,000, accounting for 35%, ranking first in the world.

Xiang Ligang also noticed that the United States, Europe, Japan and South Korea are now developing 6G's "sound waves", and they are competing for the so -called saying right, but he emphasizes that 6G is a technology, a ability, a product, and it is not the right to speak. "You can no matter how much this matter is, no matter how high the sound is, there is no real technology, ability and product, and it is useless."

"If you want to obtain a 6G lead position, you need to be in communication standards, communication system equipment, communication terminals, communication network construction, 6G -based business platform construction, business construction ... to achieve a more advantageous position. You need to lead in multiple fields, rather than a certain certain field, not a certain certain field A field leader, "Xiang Ligang said.

What can 6G of 1G more than 5G do?

"5G is already fast, what is the use of 6G?" I believe this is the biggest question in many people when they see 6G. Indeed, from 1G to 4G, the mobile communication system revolves around the transmission of information, with a larger communication capacity, faster rate, and smaller delay. Therefore, people will use "faster" to think about the communication network iteration iterative iteration. upgrade.

But in the 5G era, the change is not just "fast", but to expand mobile communication from human -oriented information consumption markets to Internet of Things and industry applications. "Simply put, the 5G era realizes the interconnection of all things from people to the Internet of Things, and 6G will further realize the‘ Wisdom Federation ’.” Qin Fei, dean of the vivo Communications Research Institute, told reporters.

Qin Fei believes that the 6G network will be a "big difference" communication network, because 6G can realize the integration of computing, perception, and AI on the basis of communication, and as a base network and information base to allow future physical physics The world and the digital world can be freely connected, interacted, and highly integrated, which is also a beautiful imagination of human beings for future digital life.

Zhang Ping, an academician of the Chinese Academy of Engineering, made such a description of 6G: "4G changes life, 5G changes society, and 6G changes the world."

"Based on 6G, combined with many technologies such as new materials, new terminals, smart human -computer interaction, integrated circuits, etc., various types of service cases such as immersive XR, holographic presentation, autonomous driving, wireless perception, Yuan universe, Yuan universe Wait. "Qin Fei said.

For example, the integration of communication perception is one of the important enable technologies of 6G. In short, the communication network can also provide perception while providing communication capabilities. "Through the 6G sympathetic integration technology, no camera, sensor, etc., as long as there is a signal of a communication network, it can achieve action recognition, speed recognition, distance recognition, angle recognition, etc. Wisdom traffic and other scenarios will provide very rich possibilities. After all, sensors are expensive, and China currently has the largest number of communication base stations in the world. "Qin Fei said.

Another important research direction of 6G technology is "calculating network integration", that is, more native computing nodes are deployed on the communication network to allow 6G networks to achieve native support computing functions. For example, to create a smart endogenous system with communication+AI. "6G can achieve signals, and the computing power can be reached and intelligent." Qin Fei said.

For ordinary users, the topic that is even more interested is what will the 6G terminals look like in the future? Qin Fei predicts that in the 6G era, smartphones will still be an important terminal form, but the terminal type will definitely be more diverse, surpassing imagination.

Qin Fei said that in addition to mobile phones, XR devices, robots, unmanned cars, drones, etc. in the next 6G era, there will also be various IoT devices, and even small to the size of the buttons. The cost is only 1 yuan. Without a battery, it can be a 6G terminal.

As for what exactly is the first 6G terminal in the public life? Qin Fei believes that although it is still difficult to conclude at present, the terminals that have market demand but currently cannot serve well, and are likely to appear first. "For example, the current XR terminal user experience is not good enough. On the one hand, it is related to the performance of the device itself, and on the other hand, it has not yet reached the communication capabilities. Because the current 5G can only solve the 'capable', and to reach it, and to reach the end of 6G can achieve 'easy to use'. "He said.

In the development process of the entire mobile communication technology, from the blankness of the 1G era, to 2G to follow, 3G breakthroughs, then 4G and 5G, eventually have the world's largest 5G network; while in the field of smartphones and smart terminals, Chinese companies have gradually become a force that cannot be underestimated by the global market. All of this allows us to look forward to the "China" in the upcoming 6G era. "China's 5G has gone in front of the world. We have reason to believe that in the current general direction, China will continue to play a very important role in the future 6G development of the world." Xiang Ligang said.
