摘　　要：通信感知一体化作为下一代无线通信的关键技术之一,将共享软硬件资源或信息,同时实现感知与通信双功能,满足多样化业务需求。目前,学术界和产业界已对通信感知一体化展开初步研究,但是其主要针对单个通信感知一体化基站的性能分析,没有考虑多小区间的干扰问题。因此,亟需针对现有研究进行系统级仿真性能评估,基于NR标准搭建系统级仿真平台,针对不同的时频域资源分配情况,分析OFDM一体化波形和OTFS一体化波形在通信感知一体化系统中的性能,并给出通信感知一体化网络的部署建议。As a pivotal technique for the next generation of wireless communication,integrated sensing and communication(ISAC)leverages shared software and hardware resources or information to simultaneously achieve dual functionalities of sensing and communication,catering to a variety of service demands.While the academic and industrial sectors have initiated preliminary research on ISAC,the focus predominantly lies on the performance analysis of individual ISAC base stations without addressing the interference issues prevalent across multiple cells.Consequently,there is an urgent need for a comprehensive system-level simulation performance evaluation.A system-level simulation platform,constructed based on the NR standard,is proposed to analyze the performance of integrated OFDM waveforms and OTFS waveforms in ISAC systems under various timefrequency domain resource allocation scenarios.This evaluation will offer insightful recommendations for the deployment of ISAC networks.
