论文摘要
这封信是三部分教程的第三部分，该教程的重点是降低速率的多访问（RSMA）6G。作为教程的第三部分，这封信提供了整合RSMA和可重构智能表面（RIS）的概述。我们首先介绍了两种潜在的PHY层技术，即RSMA和RI，包括需要将RSMA与RIS集成以及它们如何互相帮助。接下来，我们提供了RIS AID的RSMA系统的一般模型，并总结了一些关键的性能指标。然后，我们讨论了RIS AID的RSMA网络的主要优势，并说明了RIS AID的RSMA的速率区域对于完美和不完美的渠道条件。最后，我们总结了RIS AID的RSMA系统的研究挑战和开放问题。总之，RSMA是下一代多元访问（NGMA）和6G及以后的未来网络的有前途的技术。
This letter is the third part of a three-part tutorial that focuses on rate-splitting multiple access (RSMA) for 6G. As Part III of the tutorial, this letter provides an overview of integrating RSMA and reconfigurable intelligent surface (RIS). We first introduce two potential PHY layer techniques, namely, RSMA and RIS, including the need for integrating RSMA with RIS and how they could help each other. Next, we provide a general model of an RIS-aided RSMA system and summarize some key performance metrics. Then, we discuss the major advantages of RIS-aided RSMA networks, and illustrate the rate region of RIS-aided RSMA for both perfect and imperfect channel conditions. Finally, we summarize the research challenges and open problems for RIS-aided RSMA systems. In conclusion, RSMA is a promising technology for next generation multiple access (NGMA) and future networks such as 6G and beyond.
