多基站协作通感一体化体系架构及关键技术研究
Architecture and Key Technologies for Multi-Base Station Cooperative Integrated Sensing and Communication
摘要
Abstract
As one of the key technologies for 6G,ISAC enhances network intelligence and efficiency by integrating wireless communication and sensing functions to realize the coexistence and mutual collaborative gains.Limited by of single BS solutions in terms insufficient communication coverage and inadequate sensing accuracy,the multi-BS cooperative ISAC approach significantly improves the network capacity and coverage through joint data transmission and information sharing among BSs to meet the demands of network intelligence and emerging services.This paper first outlines the current research status and clarifies related concepts on mutli-BS cooperative ISAC,and summarizes the existing network architectures and the corresponding advantages.Then the key enabling technologies are reviewed,including multi-antenna techniques and their coherence design,multi-BS resource management strategies and interference suppression control,as well as intelligent clustering strategies and signal synchronization schemes under ISAC access technologies.Finally,this paper discusses the technical challenges and future development directions of multi-BS cooperative ISAC from the perspectives of computational power support and performance evaluation metrics for ISAC systems.关键词
