摘要

本文介绍了超越5G的FD-MIMO技术的下一步发展,其中FD-MIMO系统的天线以分布式方式放置。与传统的FD-MIMO系统相比,该系统被称为分布式FD-MIMO (D-FD-MIMO)系统,能够提供更高的小区平均吞吐量以及更统一的用户体验。系统级仿真结果表明,所提出的D-FD-MIMO系统的小区平均吞吐量增益是FD-MIMO系统的1.4 ~ 2倍。提出了一种基于D-FD-MIMO的概念验证(PoC)系统。讨论了D-FD-MIMO中最重要的一环——UE辅助OTA (over- air)校准。最后给出了现场试验结果。

Distributed FD-MIMO (D-FD-MIMO): from Concept to Field Test
This paper presents the next evolution of FD-MIMO technology for beyond 5G, where antennas of the FD-MIMO system are placed in a distributed manner. This system, referred to as Distributed FD-MIMO (D-FD-MIMO) system, is capable of providing higher cell average throughput as well as more uniform user experience compared to the conventional FD-MIMO system. System level simulations results show that the proposed D-FD-MIMO system achieves 1.4 – 2 times cell average throughput gain compared to the FD-MIMO system. A proof of concept (PoC) system, which is developed for D-FD-MIMO, is presented. The UE assisted over-the-air (OTA) calibration, which is the most important process of D-FD-MIMO, is discussed. Finally, the field test results are presented.
