Abstract (in Japanese) (See Japanese page) 
(in English) In fifth generation mobile communication systems, enhancement of spectral efficiency per unit area by increasing the density of transmission points per unit area is required. We have been studying large scale coordinated multi-user MIMO to enhance system capacity for 5G technology. Channel mismatch between channel estimation timing and data transmission timing due to channel variation drastically degrades throughput performance in ZF (Zero Forcing) MU-MIMO. In this paper, we propose a novel method that preferentially schedule high speed UEs experiencing severe channel variation in small-delay slots from channel estimation timing. This scheduling is realized by inputting the predicted SINR, which is estimated from channel variation between most two recent channel estimates, to PF (Proportional Fairness) scheduler. Computer simulations show that the proposed method improve mean UE throughput of high speed UEs.
