摘要:

随着新兴的集成感知与通信(ISAC)技术的发展,利用具有多域资源、多个网络元素和大规模基础设施的移动通信系统来实现协作感知,是满足万物互联(IoE)中高精度和大规模感知需求的关键途径。本文从三个视角研究了ISAC系统中的深度协作。在微观视角下,即在单个节点内部,对时-频-空-码域资源所承载的感知信息进行处理,例如相位补偿、相干积累等操作,从而提高感知精度。在中观视角下,通过多个节点的协作可以提高感知精度。我们探索了各种多节点协作感知场景,并提出了相应的挑战和未来研究趋势。在宏观视角下,来自同一运营商或不同运营商的海量基础设施可以执行协作感知,以扩展感知覆盖范围并提高感知连续性。我们研究了网络架构、目标跟踪方法以及大规模感知辅助的数字孪生构建。仿真结果证明了多节点和多资源协作感知相对于单资源或单节点感知的优越性。本文可为ISAC系统中的协作感知提供一个深入而全面的视角,以增强感知性能,支持万物互联的应用。

英文摘要:

With the emerging Integrated Sensing and Communication (ISAC) technique, exploiting the mobile communication system with multi-domain resources, multiple network elements, and large-scale infrastructures to realize cooperative sensing is a crucial approach satisfying the requirements of high-accuracy and large-scale sensing in IoE. In this article, the deep cooperation in ISAC system including three perspectives is investigated. In the microscopic perspective, namely, within a single node, the sensing information carried by time-frequency-space-code domain resources is processed, such as phase compensation, coherent accumulation and other operations, thereby improving the sensing accuracy. In the mesoscopic perspective, the sensing accuracy could be improved through the cooperation of multiple nodes. We explore various multi-node cooperative sensing scenarios and present the corresponding challenges and future research trends. In the macroscopic perspective, the massive number of infrastructures from the same operator or different operators could perform cooperative sensing to extend the sensing coverage and improve the sensing continuity. We investigate network architecture, target tracking methods, and the large-scale sensing assisted digital twin construction. Simulation results demonstrate the superiority of multi-nodes and multi-resources cooperative sensing over single resource or node sensing. This article may provide a deep and comprehensive view on the cooperative sensing in ISAC system to enhance the performance of sensing, supporting the applications of IoE.
