Abstract (in Japanese) (See Japanese page) 
(in English) In order to rapidly increasing traffic, 5G radio access network in mobile communications introduces higher frequency bands to expand channel capacity, and aims to achieve super high bit rate transmission realizing several tens Gbps by using massive MIMO. The beam tracking technique to support user mobility with narrow beam which compensates remarkable pathloss at higher frequency band is necessary. In our previous work, we evaluated the performance of beam tracking simulated as pseudo dynamic environment by turning base station using 5G testbed in an anechoic chamber. However, it is not evaluated in realistic environment that is considered practical usage cases of mobile broadband communications. Therefore, in this report, we evaluate the performance of beam tracking using 5G testbed at 15 GHz band in indoor environment. Specifically, we clarify throughput performance of downlink MIMO space multiplexing transmission with 730.5 MHz bandwidth using carrier aggregation in indoor environment using beam selection criteria based on the received power of each beam at user equipment. Experimental results in an indoor multi-path rich environment show that the peak throughput is 14.5 Gbps in a LOS environment with high mobility-reference signal received power and low antenna correlation. The results also show that the throughput of 12.5 Gbps is achieved at the cell edge 50-m away from the base station. As a result, in this experiment, over -40 dBm of received power is needed to achieve 10 Gbps.
