Recent Advances,Challenges,and Prospects of RIS-assisted Joint Beamforming Techniques
摘要
Abstract
Reconfigurable intelligent surface(RIS)stands as a pivotal enabling technology for sixth-generation(6G)wireless communication systems.RIS-aided joint beamforming,through the co-optimization of base station precoding vectors and RIS reflection phase configurations,can effectively enhance the signal-to-noise ratio(SNR)of target users and mitigate multi-user interference without augmenting radio frequency(RF)chains or transmit power,thereby concurrently improving spectral efficiency(SE)and energy efficiency(EE).This paper presents a comprehensive review of the state-of-the-art research on RIS-based joint beamforming for SE and EE optimization,encompassing single/multi-cell architectures,theoretical performance bound analysis,and simulation validation results.It further delineates the core challenges at the current stage:the limited accuracy of channel state information(CSI)estimation and the risks of physical-layer security vulnerabilities associated with RIS.Finally,it outlines future key research directions,including the design of robust optimization algorithms with global convergence and low computational complexity,as well as the promotion of their engineering deployment and performance evaluation in typical power communication scenarios.关键词
