In order to achieve China's comprehensive 5G leadership and the important strategic goal of commercial use in 2020, China mobile actively promotes the 5G industry and accelerates the maturation of the 5G industry. "On the one hand, under the overall planning and organization of imt-2020 promotion group, actively participated in 5G technology test organized by the Ministry of Industry and Information Technology, including prototype specification, test specification formulation and field test. Commercial deployment in 2020, on the other hand, as the goal, supplement 5 g technology experiment, to research and develop the products for the 5 g commercial parallel experiment, by publishing 5 g technical specifications and commercial planning, gives clear guidance to the industry, guide the industry upstream and downstream joint research and development, the breakthrough of end-to-end product hardware and architecture bottlenecks, shorten product development cycle. Liu guangyi said.
The first stage key technology verification results
It is understood that China mobile has took the lead in 2016 to complete the first stage 7 11 5 g key technology in the prototype test, the key large-scale antenna is verified (MassiveMIMO), high frequency band millimeter wave, a new waveform, a new multiple access, new coding (Polar), the feasibility of the 5 g key technology such as full duplex, 5 g key technology selection and standards laid a solid foundation. The results of key technology verification are as follows.
MassiveMIMO: increase the average spectrum efficiency by 2-3 times, and the downlink spectrum efficiency of the cell can meet the requirement of 30bit/s/Hz.
High frequency MMW: the peak speed of the hf prototype can reach 20Gbit/s+ at 1GHz bandwidth.
