非正交多址接入（NOMA）作为一种有效的无线资源共享方式，其理论基础是网络信息论。对于几代无线通信系统设计，由于收发器硬件中的有限处理能力以及延迟和连接性两者中的适度业务需求，时域、频域或码域中的正交多址方案一直是主要选择。然而，对于下一代无线电系统，鉴于其连接一切的愿景和不断发展的硬件能力，NOMA已被确定为一种有前途的技术，可帮助实现系统容量，用户连接和服务延迟的所有目标。本文系统地概述了基于统一收发器设计框架的NOMA传输的最新设计、相关标准化进展以及未来蜂窝网络中一些有前景的用例，感兴趣的研究人员可以在此基础上快速开始这一领域的研究。
Non-orthogonal multiple access (NOMA) as an efficient method of radio resource sharing has its roots in network information theory. For generations of wireless communication systems design, orthogonal multiple access schemes in the time, frequency, or code domain have been the main choices due to the limited processing capability in the transceiver hardware, as well as the modest traffic demands in both latency and connectivity. However, for the next generation radio systems, given its vision to connect everything and the much evolved hardware capability, NOMA has been identified as a promising technology to help achieve all the targets in system capacity, user connectivity, and service latency. This article provides a systematic overview of the state-of-the-art design of the NOMA transmission based on a unified transceiver design framework, the related standardization progress, and some promising use cases in future cellular networks, based on which interested researchers can get a quick start in this area.
