摘要
面向6G通信感知一体化(ISAC)系统,从业务共存、能力互助、网络共惠3个阶段研究了技术演进趋势,明确给出各阶段的系统设计目标和性能指标需求。从通信性能、感知性能、资源分配和应用场景等维度,提出影响6G ISAC系统性能的四维边界因素。基于提出的通感效率和通感效用两个新的性能指标,仿真评估了典型场景下的通信感知一体化系统性能,为后续进一步开展6G ISAC的系统设计和评估验证工作提供了重要参考。
The development of 6G integrated sensing and communication(ISAC)systems is studied from three stages:traffic coexistence,capability cooperation,and network mutualism.The target of system design and requirement of performance metrics are proposed.The influence factors called four-dimension boundary factors of ISAC are presented in the four aspects:communication performance,sensing performance,resource allocation,and application scenario.Based on two new performance metrics called ISAC efficiency and utility,the performance of ISAC is simulated in typical scenarios.Some key suggestions for system design and evaluation are proposed for the evolution of6G ISAC.
