Abstract: Mobile network is evolving from a communication-only network towards the onewith joint communication and radio radar sensing (JCAS) capabilities, that wecall perceptive mobile network (PMN). Radio sensing here refers to informationretrieval from received mobile signals for objects of interest in theenvironment surrounding the radio transceivers. In this paper, we provide acomprehensive survey for systems and technologies that enable JCAS in PMN, witha focus on works in the last ten years. Starting with reviewing the work oncoexisting communication and radar systems, we highlight their limits onaddressing the interference problem, and then introduce the JCAS technology. Wethen set up JCAS in the mobile network context, and envisage its potentialapplications. We continue to provide a brief review for three types of JCASsystems, with particular attention to their differences on the designphilosophy. We then introduce a framework of PMN, including the system platformand infrastructure, three types of sensing operations, and signals usable forsensing, and discuss required system modifications to enable sensing on currentcommunication-only infrastructure. Within the context of PMN, we reviewstimulating research problems and potential solutions, organized under eighttopics: mutual information, waveform optimization, antenna array design,clutter suppression, sensing parameter estimation, pattern analysis, networkedsensing under cellular topology, and sensing-assisted secure communication.This paper provides a comprehensive picture for the motivation, methodology,challenges, and research opportunities of realizing PMN. The PMN is expected toprovide a ubiquitous radio sensing platform and enable a vast number of novelsmart applications.
