Abstract (in Japanese) (See Japanese page) 
(in English) In 5G mobile communication systems, an effective high-capacity technology is expected by using high-density small cells. We are proposing the ultra high-density distributed antenna systems and studying the coordinated radio resource scheduling. In MU-MIMO, scheduling methods including UE selection and control of the number of multiplexed UEs affects system throughput performance. In previous work, we proposed low complexity UE selection method and evaluated the system throughput via computer simulation. In this paper, we show the proposed method can optimally control the number of multiplexed UEs in the experiment system which can transmit 32 streams at maximum.
