The fifth-generation mobile phone mobile communication standard, also known as the fifth-generation mobile communication technology, is abbreviated as 5G in English. Compared with 4G, 5G has higher speed, wider bandwidth, higher reliability and lower latency, which can meet the needs of users and industries such as virtual reality, ultra-high definition video, intelligent manufacturing and automatic driving. Application requirements. At present, 5G is still in the planning stage, and concepts and technologies have not formed a unified standard. China is vigorously carrying out the frontier layout of 5G technology and industrialization, and has made positive progress in various fields, laying a solid foundation for preempting the development opportunities of 5G.
China's 5G development statusChina's mobile communication technology started late, but it is gradually becoming a global leader in the development of 5G standards. Our country is mainly applied in the development process of 1G and 2G, and is in the stage of introduction, follow-up and imitation. Starting from 3G, our country has initially integrated into the international development trend. TD-SCDMA jointly developed by Datang Group and Siemens has become one of the three major standards in the world. In the 4G research and development, China has already developed its own TD-LTE system, and has become the mainstream standard of 4G in the world. In terms of 5G, the Chinese government, enterprises, scientific research institutions and other parties attach great importance to the frontier layout and strive to master the right to speak in the formulation of global 5G standards. China's 5G standardization research proposal has been approved at the 6th Plenary Session of the World Telecommunication Standardization Assembly (WTSA16) in 2016, which indicates that China's 5G technology research and development has been at the forefront of the world.
At the government level, the top-level frontier layout has gradually expanded, and the direction of 5G technology breakthrough has been clarified. First, China has defined the development goals and directions for the future 5G from the national macro level. "Made in China 2025" proposes to break through 5G technology and break through the core technology and system architecture of "Future Network". The "13th Five-Year Plan" proposes to actively promote 5G development, lay out future network architecture, and launch 5G commercialization by 2020. In 2013, the Ministry of Industry and Information Technology, the National Development and Reform Commission and the Ministry of Science and Technology organized the “IMT-2020 (5G) Promotion Group†(hereinafter referred to as the Promotion Group). The Promotion Group is responsible for coordinating and promoting the 5G technology R&D and testing work, and establishing 5G exchanges with countries such as Europe, America, Japan and Korea. Cooperation mechanism to promote the standardization and industrialization of global 5G. The promotion team successively released research results such as “5G Vision and Demand White Paper†and “5G Concept White Paperâ€, which clarified the 5G technical scenarios, potential technologies, key performance indicators, etc. Some indicators were included in the established 5G demand report by the ITU. Second, relying on major national special projects, etc., actively organize and promote the breakthrough of 5G core technology. The national "973" program began to lay out the next generation mobile communication system as early as 2011. In 2014, the National “863†Program launched the “Preliminary Implementation of 5G Mobile Communication System†project. Around the 5G core key technologies, 11 sub-projects were deployed. In 2016, the “New Generation Broadband Wireless Mobile Communication†National Science and Technology Major Project launched a comprehensive 5G technology R&D test in China. The first phase of testing has been completed and all key technologies have been verified. There will be three 5G-related R&D projects in the 2017 National Science and Technology Major Project. According to the planned time, 2017-2018 will fully promote the 5G technology R&D test in China's second and third phases.
At the enterprise level, domestic leading companies have already gained first-mover advantage. Huawei, ZTE, Datang and other leading communications equipment companies in China have attached great importance to the R&D of 5G technology and have been recognized by the industry in terms of standards development and industrial applications. For example, ZTE completed the pre-commercial testing of the world's first TDLTE 3D/Massive MIMO base station in Shenzhen in 2014, and began to deploy 10 commercial networks worldwide in 2016. Datang launched the 5G pre-research in 2011, and proposed the 5G key capability indicators and values ​​in 2013, which was included in the technical indicators of the 5G vision and framework proposal by the ITU. In addition, China Mobile and other telecom operators are also actively deploying the future 5G industry. For example, China Mobile has released the China Mobile Vision 2020+ White Paper, hoping to work with all parties to realize the vision of “connecting unlimited possibilitiesâ€. Huawei has made major breakthroughs in 5G new air interface technology, networking architecture, virtual access technology and new RF technology. Recently, Huawei's polar code scheme has become a 5G international standard code solution. Although it is only the initial stage of the 5G standard, it has greatly boosted the confidence of China's 5G standard research and development.
China's 5G future development trendFirst, product technology has gradually focused on four major application scenarios. The promotion group concluded that the future 5G applications are mainly concentrated in four scenarios: continuous wide-area coverage scenarios such as high-speed rail and subway; hot-spot high-capacity scenarios such as residential areas, office areas, and open-air gatherings; low-power consumption such as smart cities, environmental monitoring, and intelligent agriculture. Large connection scenarios; low latency and high reliability scenarios such as car networking, industrial control, virtual reality, and wearable devices. Therefore, 5G technology and product development should also focus on these four scenarios, and make timely cutting-edge technology and product development.
Second, 5G technology will stimulate new consumer demand. An important feature of 5G is that it can realize "the connection between people, people and things, things and things", form the Internet of Everything, and integrate it in all aspects of work and study, leisure and entertainment, social interaction, industrial production. The gradual enrichment of consumption patterns will promote major changes in user experience requirements, further inspiring new industries, new formats and new models. To this end, we must fully prepare the technology and products, track the dynamic changes of technology and products in a timely manner, and deploy disruptive technologies and products as soon as possible.
The third is the acceleration of industrial integration and change. Based on the support of 5G technology, the integration and development of cross-industry will be further strengthened. The new informationization and industrialization will be deeply integrated, which will lead to deep changes in the industrial field. 5G technologies such as mobile IoT scenarios will penetrate into various industries such as consumption, production, sales, and service, and promote the development of digitalization, intelligence, and synergy in research and development, design, marketing, and service, and realize the entire life cycle of the industrial sector. Intelligent management of the full value chain.
Several issues that need to be focused on in the futureFirst, we must grasp the initiative of 5G standard construction and industrialization. Currently in the 5G standardization research and development stage, we must continue to strengthen communication with international standards organizations such as ITU and 3GPP, and build an international 5G test platform to form a relatively uniform global 5G standard. The competition of the future 5G is not only a competition for standards, but also a competition for the application level of 5G industrialization. It is necessary to lay out the 5G communication infrastructure construction in advance and strengthen the technological breakthroughs of key equipment such as "baseband chips". At the same time, it will promote the coordinated development of equipment manufacturers, telecom operators, test equipment manufacturing, terminal products, network management and other parties to reserve for future industrialization.
The second is to focus on the integration of innovative research in vertical industries. It can be foreseen that with the gradual promotion of 5G technology and applications, the integration of technology and industry will accelerate, and new formats and new models will continue to emerge. It is necessary to do a good job of tracking the demand of 5G technology in the vertical industry, strengthen the connection with enterprises and individual users, and discover new growth points in time. In the near term, vehicle networking, industrial control, virtual reality, and the Internet of Things will be the key areas for 5G support. It is necessary to focus on key technology R&D and application demonstrations, and to play the role of 5G in supporting the development of the industry.
The third is to attach great importance to the construction of the information security system. 5G's cloud and virtualization technologies can meet the demand of massive data in mobile networks, and bring rich services to users. At the same time, the requirements for data privacy and security protection are also significantly improved. 5G has a high transmission rate and diverse services, and it is easier for hackers to find vulnerabilities in mobile terminals and launch attacks. Once the vulnerability is compromised, the consequences will be unimaginable. Therefore, on the one hand, we must make a breakthrough in the 5G security protection technology, on the other hand, we must strengthen the construction of the network security system.
