| 将非正交多址接入(Non-orthogonal Multiple Access,NOMA) 与通信感知一体化(Integrated Sensing and Communications,ISAC) 结合的NOMA-ISAC系统成为6G的一个重要研究方向。通过文献梳理，将NOMA-ISAC系统的资源分配问题分成两个大类和四个小类进行概述。首先，从技术理论创新的角度对NOMA-ISAC系统功率资源分配和时频资源分配进行了概述；其次，从系统架构创新的角度对可重构智能反射面(Intelligent Reconfigurable Surfaces,IRS)结合的NOMA-ISAC系统资源分配、其他新兴技术结合的NOMA-ISAC系统资源分配两方面概述了 NOMA-ISAC系统资源分配的研究现状；最后，总结了当前研究中面临的主要挑战，并展望了 NOMA-ISAC系统未来的研究趋势。 |

| Abstract: |
| Combining non-orthogonal multiple access(NOMA) with integrated sensing and communications(ISAC) will become an important research direction for 6G.Through a review of the literatures,the resource allocation problem in NOMA-ISAC system is categorized into two main categories and four subcategories for comprehensive discussion.Firstly,an overview of power resource allocation,time and frequency resource allocation in the NOMA-ISAC system is provided from the perspective of technological theoretical innovation.Secondly,the research status in NOMA-ISAC system resource allocation is summarized from the perspective of system architecture innovation,including the combination of intelligent reconfigurable surfaces(IRS) and other emerging technologies.Finally,the main challenges faced in current research are summarized,and the future research trends of NOMA-ISAC systems are discussed. |
| Key words: non-orthogonal multiple access(NOMA) integrated sensing and communications(ISAC) intelligent reconfigurable surfaces(IRS) resource allocation |
