摘要:

下一代无线网络需要更严格的性能水平。可重构智能表面(RIS)和速率分割多址(RSMA)等新技术有望满足部分性能要求,包括以更低成本实现更高用户速率。RSMA提供了一种混合多用户消息的新方式,而RIS则提供可控的无线环境。本文针对下一代(xG)无线通信系统,全面综述了可重构智能表面(RIS)与速率分割多址(RSMA)协同作用的各个方面。具体而言,本文研究了60多篇论文,涉及20多种不同系统模型;在这些模型中,RIS辅助的RSMA系统在和速率或中断概率方面相较传统RSMA模型表现出性能优势。这些模型包括反射式RIS、同时透射与反射表面(STAR-RIS)以及透射式表面。用于RIS辅助RSMA通信的最新资源管理方法采用传统优化技术和/或机器学习技术。我们概述了主要研究挑战和多个未来研究方向。

英文摘要:

Next generation wireless networks require more stringent performance levels. New technologies such as Reconfigurable intelligent surfaces (RISs) and rate-splitting multiple access (RSMA) are candidates for meeting some of the performance requirements, including higher user rates at reduced costs. RSMA provides a new way of mixing the messages of multiple users, and the RIS provides a controllable wireless environment. This paper provides a comprehensive survey on the various aspects of the synergy between reconfigurable intelligent surfaces (RISs) and rate splitting multiple access (RSMA) for next-generation (xG) wireless communications systems. In particular, the paper studies more than 60 articles considering over 20 different system models where the RIS-aided RSMA system shows performance advantage (in terms of sum-rate or outage probability) over traditional RSMA models. These models include reflective RIS, simultaneously transmitting and reflecting surfaces (STAR-RIS), as well as transmissive surfaces. The state-of-the-art resource management methods for RIS-assisted RSMA communications employ traditional optimization techniques and/or machine learning techniques. We outline major research challenges and multiple future research directions.
