Yesterday, the Ministry of Industry and Information Technology issued the "Notice on Starting the Third Phase of 5G Technology Research and Development Tests" (<Notice>). The "Notice" pointed out that in the third stage, it is necessary to clarify the test objectives, accelerate the construction of the test environment and equipment research and development, carry out integration tests, promote the simultaneous development of 5G-related businesses and applications, and strive to promote the main links of the 5G industry chain to basically reach commercial use by the end of 2018 Level.

According to the timetable of the International Organization for Standardization 3GPP, 3GPP R16 (complete service) 5G standard formulation will be completed in the second quarter of 2018. After that, 5G will officially move from research and development to commercial use. At present, my country is carrying out the 5G technology research and development process in an orderly manner. Not long ago, my country took the lead in releasing the 5G intermediate frequency band plan, which clarified the 3300-3400MHz, 3400-3600MHz and 4800-5000MHz frequency bands as the working frequency bands of the 5G system. . Today, the work plan and goals of the third phase of 5G R&D trials have also been clarified. With 5G technology R&D trials as a platform, my country will continue to support 5G technology research and development, standardization and industrial development, and promote the formation of a complete 5G industry chain, which is 5G by 2020. The successful realization of the commercial goals laid the foundation. The third phase of the R&D test focuses on 5G commercial applications. The Ministry of Industry and Information Technology pointed out that this stage focuses on product R&D, verification and industrial collaboration before 5G commercial use, and conducts pre-commercial interconnection testing.

The "Notice" requires that: 1. Clear test objectives. It is necessary to take the lead in formulating test plans and test specifications, and clarify the test objectives, content and index requirements of the third phase. Focus on product R&D, verification and industry collaboration before commercial use of 5G, carry out pre-commercial equipment single station, networking, interoperability, and interconnection testing of systems, chips, meters and other upstream and downstream industrial chains, and comprehensively promote the main links of the industrial chain Basically reach the commercial level. 2. Build a test environment. Coordinate resources to speed up the completion of the construction and optimization of the 5G laboratory of China Academy of Information and Communications Technology and the Beijing Huairou field test system, forming a multi-manufacturer, indoor and outdoor integrated test environment to ensure that the third phase test requirements are met on time. 3. Speed ​​up equipment research and development. Please develop equipment as soon as possible in accordance with the "Notice on the Use of 3300-3600MHz and 4800-5000MHz Frequency Bands for Fifth Generation Mobile Communication Systems" (No. [2017] No. 276 of the Ministry of Industry and Information Technology) of the Ministry of Industry and Information Technology. Launched 5G pre-commercial products at the same time as international standards. 4. Carry out integration trials. Aiming at the three scenarios of enhanced mobile broadband, low latency, high reliability, and low power consumption, large connections, we will carry out technical tests related to typical 5G applications to promote the development of 5G services and applications. 5. Strengthen overall planning. 5G standard research, equipment research and development, and technical testing are coordinated in an orderly manner. Accelerate the schedule, carefully organize relevant enterprises and units, and strive to achieve the basic objectives of the third phase of the trial by the end of 2018, and support the full launch of my country's 5G scale trials.
