作为多址接入家族的最新成员，非正交多址接入（NOMA）最近已经被提出用于3GPP LIE，并且被设想为5G移动的网络的重要组成部分。NOMA的关键特征是在相同的时间/频率/代码，但具有不同的功率电平，这产生了显着的频谱效率增益比传统的正交MA服务多个用户。本文对这一新兴技术进行了系统的论述，从它与MIMO技术的结合到NOMA协作，以及NOMA与认知无线电之间的相互作用。本文还回顾了有关在LTE和5G网络中实施NOMA的标准化活动的最新进展。
As the latest member of the multiple access family, non-orthogonal multiple access (NOMA) has been recently proposed for 3GPP LIE and is envisioned to be an essential component of 5G mobile networks. The key feature of NOMA is to serve multiple users at the same time/frequency/code, but with different power levels, which yields a significant spectral efficiency gain over conventional orthogonal MA. The article provides a systematic treatment of this newly emerging technology, from its combination with MIMO technologies to cooperative NOMA, as well as the interplay between NOMA and cognitive radio. This article also reviews the state of the art in the standardization activities concerning the implementation of NOMA in LTE and 5G networks.
