Radio Resource Management in Joint Radar and Communication: A Comprehensive Survey

Abstract

Joint radar and communication (JRC) has recently attracted substantial attention. The first reason is that JRC allows individual radar and communication systems to share spectrum bands and thus improves the spectrum utilization. The second reason is that JRC enables a single hardware platform, e.g., an autonomous vehicle or a UAV, to simultaneously perform the communication function and the radar function. As a result, JRC is able to improve the efficiency of resources, i.e., spectrum and energy, reduce the system size, and minimize the system cost. However, there are several challenges to be solved for the JRC design. In particular, sharing the spectrum imposes the interference caused by the systems, and sharing the hardware platform and energy resource complicates the design of the JRC transmitter and compromises the performance of each function. To address the challenges, several resource management approaches have been recently proposed, and this paper presents a comprehensive literature review on resource management for JRC. First, we give fundamental concepts of JRC, important performance metrics used in JRC systems, and applications of the JRC systems. Then, we review and analyze resource management approaches, i.e., spectrum sharing, power allocation, and interference management, for JRC. In addition, we present security issues to JRC and provide a discussion of countermeasures to the security issues. Finally, we highlight important challenges in the JRC design and discuss future research directions related to JRC.

OFDM-IM for Joint Communication and Radar-Sensing: A Promising Waveform for Dual Functionality

“…Fundamental concepts and important performance metrics have been discussed, and resource management approaches have been analyzed for JCR in the study by Luong et al (2021). Waveform design plays a critical role in the JCR concept, and a single novel waveform for both radar and communication functionalities, without a reduction in performance of either, is yet to exist.…”

Novel Cooperative Scheme Based on Joint Band Assignment and Power Allocation for a Coexisting Radar-Communications System

“…Motivated by the great demand for performance improvement and resource management in CRC systems, a cooperative design has attracted substantial attention for recent years. Unlike the conventional noncooperative systems, the cooperative schemes aim to share the information and adaptively allocate the resources between the subsystems so as to enhance the performance of the radar and communication functions [ 20 ]. For example, a cooperative CRC system is developed in [ 21 ], where a water-filling successive interference cancellation (SIC) technique is employed at the joint radar-communications receiver to maximize the data rate.…”

Maximum-Service Channel Assignment in Vehicular Radar-Communication

“…Radar-communication spectrum sharing has two main forms; spectral coexistence and Dual Function Radar Communication (DFRC) [2], [3]. In coexistence scenarios, different radar and communication devices share the same spectrum, and consequently mutual interference should be managed either proactively or reactively.…”
