NR MIMO增强演进及标准化进展

Evolution and standardization progress for NR MIMO enhancement

大规模多输入多输出(multiple-input multiple-output,MIMO)技术作为5G的关键使能技术之一,在5G网络的商用部署中发挥了重要的作用。结合5G系统的演进与实际部署经验,3GPP Release 17在MIMO增强演进方面做了一系列标准化工作。聚焦3GPP标准化工作,介绍并分析了MIMO增强的标准化进展,并重点阐述了多波束增强与多传输点传输增强。最后对3GPP Release 18 MIMO增强标准化工作进行了展望。

As one of the key technologies of 5G,massive multiple-input multiple-output(MIMO)has played an im-portant role in the commercial deployment of 5G networks.Based on the deployment experience of 5G systems,3GPP Release 17 has done a series of standardization work on MIMO evolution enhancement.Focusing on 3GPP standardization work,the standardization progress of related MIMO enhancement schemes,especially for multi-beam enhancement and multi-TRP enhancement,was introduced and analyzed.In the end,potential future work of 3GPP Release 18 MIMO enhancement was summarized.
