| 摘 要： | 随着无线通信5G/6G技术的发展，基于通信雷达一体化(RadCom)技术的新兴业务不断涌现。为实现基于5G新空口(NR)的RadCom，需考虑3GPP定义的最新5G NR无线通信标准所涵盖的多种部署场景，然而，在不同场景中雷达探测性能会受限于5G NR参数集。因此，需在特定的场景下，探索采用不同5G NR参数集的雷达探测性能。以车联网(IoV)场景的雷达探测需求和基础雷达性能参数计算准则为约束，给出了不同5G NR参数集条件下的雷达探测性能仿真分析，为未来基于5G NR标准及其部署场景的RadCom系统设计及优化给出指导性建议。

| Abstract: | With the development of wireless communication 5G/6G technology, a variety of new services based on the fusion of communications and radar (RadCom) technology continue to emerge. In order to implement RadCom based on 5G new radio (NR), many different deployment scenarios covered by the latest 5G NR wireless communication standard defined by 3GPP need to be considered. However, radar detection performance is limited by 5G NR numerology in different scenarios. Therefore, it is necessary to explore the radar detection performance with different 5G NR numerology in specific scenes. This paper takes the radar detection requirements of internet of vehicle (IoV) scenes and the calculation criteria of basic radar performance parameters as constraints, and presents the simulation analysis of radar detection performance under different 5G NR numerology. Some instructive suggestions are given for the designs and optimizations of RadCom systems based on 5G NR standard and deployment scenarios in the future. |
