摘要:

移动网络正从单纯的通信网络向具有通信和雷达/无线电感知(JCAS)能力的感知移动网络(PMN)发展。在PMNs中,JCAS将传感集成到通信中,共享大部分系统模块和相同的传输信号。PMN有望提供一个无处不在的无线电传感平台,并实现大量新颖的智能应用,同时提供不受损害的通信。在本文中,我们提出了实现PMN的动机,方法,挑战和研究机会,提供了一个全面的调查,主要是在过去十年中开发的系统和技术。首先回顾了共存的通信和雷达系统的工作,我们强调他们的限制解决干扰问题,然后介绍JCAS技术。然后,我们建立了JCAS在移动网络的背景下,并设想其潜在的应用。我们将继续简要回顾三种类型的JCAS系统,特别关注它们在设计理念上的差异。然后,我们介绍了PMN的框架,包括系统平台和基础设施,三种类型的传感操作,和可用于传感的信号。随后,我们讨论了所需的系统修改,使目前的通信基础设施上的传感。在PMN的背景下,我们回顾了刺激的研究问题和潜在的解决方案,组织在九个主题:性能界限,波形优化,天线阵列设计,杂波抑制,传感参数估计,传感模糊的分辨率,模式分析,网络传感蜂窝拓扑结构下,和传感辅助通信。在论文的最后,我们列出了上述主题的关键开放研究问题,并分享了我们学到的一些教训。

英文摘要:

Mobile network is evolving from a communication-only network towards one with joint communication and radar/radio sensing (JCAS) capabilities, that we call perceptive mobile network (PMN). In PMNs, JCAS integrates sensing into communications, sharing a majority of system modules and the same transmitted signals. The PMN is expected to provide a ubiquitous radio sensing platform and enable a vast number of novel smart applications, whilst providing non-compromised communications. In this paper, we present a broad picture of the motivation, methodologies, challenges, and research opportunities of realizing PMN, by providing a comprehensive survey for systems and technologies developed mainly in the last ten years. Beginning by reviewing the work on coexisting communication and radar systems, we highlight their limits on addressing the interference problem, and then introduce the JCAS technology. We then set up JCAS in the mobile network context and envisage its potential applications. We continue to provide a brief review of three types of JCAS systems, with particular attention to their differences in design philosophy. We then introduce a framework of PMN, including the system platform and infrastructure, three types of sensing operations, and signals usable for sensing. Subsequently, we discuss required system modifications to enable sensing on current communication-only infrastructure. Within the context of PMN, we review stimulating research problems and potential solutions, organized under nine topics: performance bounds, waveform optimization, antenna array design, clutter suppression, sensing parameter estimation, resolution of sensing ambiguity, pattern analysis, networked sensing under cellular topology, and sensing-assisted communications. We conclude the paper by listing key open research problems for the aforementioned topics and sharing some lessons that we have learned.
