Abstract:

The new radio (NR) of 5G has gathered three main application scenarios and has broken the restrict of the air interface transmission,laying a solid foundation of the information science.Massive MIMO based base station (MMBS) has become the important fulcrum in the implementation deployment of 5G networks.In order to determine performance of the MMBS in sub 6 GHz band,the physical (PHY) layer techniques were firstly introduced,then,for providing a benchmark of the MMBS products,the evaluation method for upbound of the PHY performance and the PHY performance under the fast fading channel environment was given.Based on that,the current mainstream MMBS performance testing methods were analyzed,and a performance testing scheme was proposed which had been suitable for current commercial version of the MMBS.The proposed scheme can be used to test the function and performance of the products with 5G technique.By the end of 2019,there are many manufacturers of MMBS products have been tested by this solution.

Key words: 5G MMBS, performance emulation, performance test
