摘　　要：第六代移动通信系统面临着前所未有的技术挑战,NOMA作为解决6G关键问题的重要手段,近年来得到了广泛的研究讨论。与传统正交多址接入方案相比,NOMA的主要特点是通过非正交资源分配服务更多数量的用户,并通过干扰消除技术抵消用户间干扰的影响。首先介绍了NOMA的基本理论,然后讨论了6G场景下NOMA关键技术的理论研究及工程实现情况,最后对NOMA的应用场景和未来研究方向进行了描述与展望。The sixth-generation mobile communication systems are facing the unprecedented technical challenges.As one of important techniques to address those challenges,non-orthogonal multiple access(NOMA)has been widely investigated and discussed in recent years.Compared with conventional orthogonal multiple access,the main characteristic of NOMA is able to serve more users by non-orthogonal resource allocation and eliminate the inter-user interference by interference cancellation techniques.This paper first introduces the basic theory of NOMA.Then the theoretical research and practical implementations of NOMA key technologies in 6G scenarios are discussed.Finally,the application scenarios and future research directions are described and prospected for NOMA.
