非正交多址接入（NOMA）是潜在的能够绕过经典的正交多址接入方案的限制。因此，它最近在工业界和学术界都受到了极大的研究关注。本文主要研究多天线技术在NOMA网络中的应用，重点研究MIMO-NOMA网络的速率域，回顾了两种流行的多天线辅助NOMA结构，并着重分析了单载波和多载波MIMO-NOMA网络的资源管理问题。本文还指出了解决多天线NOMA网络实际实现约束的几种有效方法。最后，在多天线辅助NOMA的背景下，提供了一些有前途的开放式研究方向。
Non-orthogonal multiple access (NOMA) is potentially capable of circumventing the limitations of the classic orthogonal multiple access schemes. Hence, it has recently received significant research attention in both industry and academia. This article is focused on exploiting multiple antenna techniques in NOMA networks, with an emphasis on investigating the rate region of MIMO-NOMA, while reviewing two popular multiple antennas aided NOMA structures, as well as underlining resource management problems of both single-carrier and multi-carrier MIMO-NOMA networks. This article also points out several effective methods of tackling the practical implementation constraints of multiple-antenna NOMA networks. Finally, some promising open research directions are provided in the context of multiple- antenna-aided NOMA.
