my country plans to complete 5G independent network testing within this year, reaching the predecessor

"At the" 2018 5g network innovation seminar ", Xu Fei, deputy chief engineer of the Institute of technology and standards of China Academy of information and communications, said that at present, various system manufacturers in China have completed the non independent networking test, the main functions meet the specifications, and the functional integrity and interoperability still need to be strengthened. It is planned to complete the independent networking test within this year to achieve pre commercialization. Up to now, 5g international standard has been basically established, and China has made positive contributions to 5g international standard. According to Xu Fei, Chinese Manuscripts account for 32% of 5g standards, including flexible system design, wireless basic technology, large-scale antenna, service architecture, access network architecture, 5g voice scheme, etc. At present, the imt-2020 (5g) promotion team has completed the verification of key technologies in the first stage of 5g technology test and the verification of technical solutions in the second stage. Now it is actively promoting the test of system networking verification in the third stage. Under the NSA networking mode, the main indoor test contents include the basic functions of the physical layer, the basic functions of RRC protocol, physical channel, link adaptation and scheduling En-dc dual connection test, multi antenna technology, cu-du separation architecture, RF test, NSA core network test; The outfield test is mainly the test of wireless networking. According to Xu Fei, China's 5g technology test, at present, various system manufacturers have completed the non independent networking test, the main functions meet the specifications, and the functional integrity and interoperability still need to be strengthened. It is planned to complete the independent networking test within this year to achieve pre commercialization. At the same time, we will vigorously promote 5g enhanced bandwidth applications, continue to promote 5g integrated applications such as Internet of vehicles and industrial Internet, and deepen cooperation. 5g standards, industries, applications and policies need to strengthen international exchanges and cooperation to jointly promote the success of 5g in the world.
