l correlation. The correlation is low enough, achieving more than 4.8 Gbps even in Rank-8 of 64-QAM R = 0.8 when the UE side is using an OMNI antenna and the space of the BTS antenna branch is changed to 102 in the horizontal direction and 6.61 in the vertical direction. Moreover, we also showed that Rank-8 transmission of more than 9.6 Gbps in the downlink can be achieved in the long corridor environment exhibiting LOS propagation with many reflection paths. Section 11.4 presented field experiments on the downlink throughput and SNR per- formance of a beam tracking PoC system targeting 5G millimeter wave radio access at 73 GHz with 1 GHz bandwidth in courtyard, shopping mall, and street canyon envi- ronments. The majority of the area in the courtyard and street canyon environment is LOS, while the shopping mall environment is 69% NLOS. The results show that a maxi- mum throughput of over 2 Gbps using rate 7/8 coded 16-QAM modulation is achieved for 87%, 34%, and 28% of each of the respective environments. 1 Gbps is achieved in the downlink for 95%, 45%, and 91% of each of the respective environments. The beam tracking achieves high availability of coverage and seamless mobility not only in LOS environments but also NLOS conditions through reflected paths. References 1 N. Tran, T. Imai, K.
