At the recent 5G summit 2018, Chen Xiongxiong, deputy minister of the Ministry of Industry and Information Technology (MIIT), disclosed some progress in the global and China’s 5G standards, commercial and equipment. Chen Xiongxiong said that the international standard of the first phase of 5G systems has been completed, and Chinese enterprises have fully participated in the formulation of 5G international standards. As of now, many technical solutions such as the new network architecture have been adopted by international standards organizations.
At present, China has broken through key technologies such as large-scale antennas and network coding, and various testing work will be accelerated to ensure that the commercial system equipment conforming to the first version of 5G international standards will be launched before the end of this year. Wang Zhiqin, head of the national 5G promotion group, also revealed that the second version of the 5G international standard has been launched, focusing on optimizing the enhanced applications of 5G for the Internet of Things (IoT), such as media, virtual reality, drones, power industry, public security systems, etc. It is expected that commercial and pre-commercial 5G systems will be available by the end of this year.
On June 14th, at 3GPP RAN Plenary held in San Diego, USA, 3GPP announced that it has completed the 5G new air interface (5G NR) specification for independent networking (SA) on time, and will deploy 5G NR with 5G core network to support end-to-end new features.
