Research on integrated sensing and communication technology towards 5G evolution

Abstract： Integrated Sensing and Communication (ISAC),as a core technology for 5.5G/6G systems,breaks the functional boundaries of traditional systems by deeply integrating communication and sensing capabilities,enabling shared spectrum and hardware resources,and driving communication networks toward multi-dimensional sensing.This paper systematically explores the core principles,technical challenges,and future directions of ISAC.Technically,ISAC leverages the transmission and reflection characteristics of wireless signals to achieve efficient fusion of environmental sensing and data transmission through joint waveform design,multi-station collaborative sensing architectures,and self-interference cancellation.However, its development faces critical challenges such as joint optimization of communication-sensing waveforms,dynamic scheduling of network resources,multi-station synchronization,and standardization.Typical application scenarios include intelligent transportation,industrial Internet,and space-air-sea-ground collaborative networks,requiring sub-meter-level sensing accuracy,millisecond-level latency,and high reliability.Future advancements focus on four key directions: optimization of terahertz-band devices and intelligent metasurfaces,AI-driven joint communication-sensing frameworks,intent-driven cloud-edge-terminal dynamic architectures,and lightweight security mechanisms.By addressing foundational theories like ISAC joint information theory and energy efficiency models,and promoting industry-academia-research collaborative validation,ISAC will accelerate the deep integration of the physical and digital worlds,emerging as a cornerstone enabling technology for global intelligent networks.
