摘　　要：随着第五代移动通信技术(5th Generation Mobile Communication Technology,5G)网络的大规模商业化部署,超5G(Beyond 5G,B5G)和第六代移动通信技术(6th Generation Mobile Communication Technology,6G)逐渐成为研究热点。非正交多址接入(Non-Orthogonal Multiple Access,NOMA)作为一种新型接入技术,有望成为B5G和6G网络中的关键多址接入技术。与此同时,多载波通信具有抗频率选择性衰落和高频谱效率的特点,因此将多载波技术与NOMA相结合成为B5G和6G的一个重要研究方向。从能效、功耗以及速率方面概述了多载波非协作NOMA、多载波协作NOMA的资源分配问题。探讨当前研究存在的一些缺陷与不足,并展望多载波NOMA系统资源分配问题的未来研究方向。With the large-scale commercial deployment of the 5th Generation Mobile Communication Technology(5G)networks,concepts such as Beyond 5G(B5G)and the 6th Generation Mobile Communication Technology(6G)have gradually become research hotspots.As a new access technology,Non-Orthogonal Multiple Access(NOMA)is expected to become the key multiple access technology in B5G and 6G networks.Meanwhile,multi-carrier communication can overcome frequency selective fading and achieve high spectral efficiency.Therefore,the combination of multi-carrier technology and NOMA will become an important research direction for B5G and 6G.The resource allocation of multi-carrier NOMA and multi-carrier cooperative NOMA from the aspects of energy efficiency,power consumption and rate are summarized.Some shortcomings and deficiencies of current research are discussed,and the future research direction of multi-carrier NOMA resource allocation problem is prospected.
