Review of RIS-assisted Integrated Sensing and Communication Beamforming Technology
摘要
Abstract
Integrated Sensing and Communication(ISAC)is one of the key technologies for 6th Generation Mobile Networks,(6G),effectively addressing the increasingly severe spectrum congestion issue while meeting the ubiquitous demands for sensing and communication.Meanwhile,Reconfigurable Intelligent Surfaces(RIS)have emerged as a promising solution to assist ISAC systems due to their ability to intelligently manipulate wireless propagation environments in an energy-efficient and effective manner.The focus is mainly placed on the beamforming technology of RIS-assisted ISAC.First,traditional ISAC technologies are introduced,and then the basic principles of different RIS and their applications in ISAC systems are discussed.The research status of RIS-assisted ISAC beamforming technology from the perspectives of Radar Communication Coexistence(RCC)and Dual-Functional Radar Communication(DFRC)is reviewed.Finally,the challenges faced in the design of RIS-assisted ISAC beamforming and future research directions are also discussed,laying a foundation for advancing the development and practical application of this field.关键词
