Abstract

Massive MIMO is a key feature for improving spectral efficiency in 5G system. Since massive MIMO has been standardized in 3GPP Re1-13 (LTE-Advanced Pro), a next generation of massive MIMO standard is now available in Rel-15, a.k.a New Radio (NR), for 5G, which is aiming at further improving the average spectral efficiency with more antenna elements over the higher frequency band. In particular, beam-based air interface for above 6GHz band involves with various antenna configurations and feedback schemes, requiring a more complex testbed for system-level performance evaluation. In this paper, we examine the multi-antenna technologies in 3GPP NR specification, so as to develop its system-level model in 5G K-SimSys, which has been designed and implemented to provide an open platform and testbed for evaluating the system-level performance for 5G system. Its actual implementation is detailed along with the overall platform architecture for modular and flexible design. Then, its actual performance is demonstrated for one of the precoding matrices in the NR specification as an example.

大规模MIMO系统级评估的5G K-SimSys

大规模MIMO是5G系统提高频谱效率的关键特征。由于大规模MIMO已在3GPP Re1-13 (LTE-Advanced Pro)中标准化，因此下一代大规模MIMO标准现已在Rel-15中推出，即5G的新无线电(NR)，旨在通过在更高频段上使用更多天线单元进一步提高平均频谱效率。特别是6GHz以上频段的波束空中接口涉及各种天线配置和反馈方案，需要更复杂的测试平台进行系统级性能评估。本文对3GPP NR规范中的多天线技术进行了研究，建立了5G K-SimSys系统级模型，并设计实现了该模型，为评估5G系统级性能提供了一个开放的平台和测试平台。详细介绍了其实际实现以及模块化和灵活设计的整体平台架构。然后，以NR规范中的一个预编码矩阵为例，演示了其实际性能。
