Abstract

A massive multiple-input multiple-output (M-MIMO) technology was introduced for 5G in millimeter-wave (mmW) bands such as 28 GHz. Further enhancement of 5G, so-called 5G Evolution (5GE) is expected to exploit advanced beamforming technologies and M-MIMO technologies combined with base station (BS) cooperation in order to achieve more stable and higher data-rate mmW transmission. For 6G, extremely high data rate exceeding 100 Gbps is required, and hence so-called sub-terahertz wave targeting the frequency from 100 GHz to 300 GHz has attracted much attention. This paper introduces our recent studies on M-MIMO technologies for 5GE and 6G. Concretely, it shows experimental results of M-MIMO BS cooperation technologies for mmW 5GE. For 6G, in link-level simulations using 100 GHz-band M-MIMO technology, over-100 Gbps downlink throughput and coverage performances are clarified. In addition, 100 GHz-band system-level performances are shown by our developed 6G simulator employing multiple M-MIMO BSs in a future shopping mall environment.
面向5G演进和6G的大规模MIMO技术研究进展
5G在28ghz等毫米波(mmW)频段引入了大规模多输入多输出(M-MIMO)技术。5G的进一步增强,即所谓的5G演进(5GE),预计将利用先进的波束成形技术和M-MIMO技术与基站(BS)合作相结合,以实现更稳定和更高数据速率的毫米波传输。对于6G,需要超过100gbps的极高数据速率,因此针对100ghz至300ghz频率的所谓次太赫兹波备受关注。本文介绍了我们在5g和6G的M-MIMO技术方面的最新研究成果。具体展示了mmw5ge下M-MIMO - BS协同技术的实验结果。对于6G,在使用100 ghz频段M-MIMO技术的链路级模拟中,阐明了超过100 Gbps的下行链路吞吐量和覆盖性能。此外,我们开发的6G模拟器在未来的购物中心环境中采用多个M-MIMO BSs,展示了100 ghz频段系统级性能。
