摘要：

5G communication introduces analog beamforming (BF) using massive MIMO (M-MIMO) in millimeter-wave (mmW) bands. 5G evolution, which will be actualized around 2025, replaces analog BF with hybrid or fully digital BF that improves mmW-band downlink and uplink transmission performances. In addition, cooperation technologies among of multiple base stations (BSs) are required to provide stable and reliable while cell switching in the mmW bands, even when mobile stations (MSs) travel at high speed. This paper verifies effectiveness of proposed BS cooperation technologies by both computer simulations and outdoor experimental trials. In this paper, three BSs using digital BF are cooperated to transmit signals while orthogonalizing two MSs that move at velocity of 90 km/h simultaneously. These evaluation shows that BS cooperation maintains the higher throughput in a wider area than non-BS cooperation.
