摘　　要：随着无线通信的发展,以中继为代表的协作通信技术被认为是未来无线通信系统中的关键技术之一。利用中继可以以较小的代价扩展小区覆盖范围和增加系统容量。目前,固定中继的研究已日趋成熟,移动中继正成为一个新的研究热点。由于移动中继本身的特性,它在带来诸多好处的同时也面临一些挑战。文中阐述了移动中继的研究现状,介绍了移动中继的应用场景,对其关键技术进行了综述与展望。With the development of wireless communication,cooperative communication technology,such as relay,is regarded as one of the key technologies in future wireless communication system. Relay can be configured to provide coverage extension and capacity increase in a cost-effective manner. Currently,the study on fixed relay has been fruitful,and mobile relay is becoming a hot topic. Due to the characteristic of the mobile relay itself,it brings many benefits while posing some new challenges. In this paper,a survey on mobile relay is presented,which first demonstrates the applications of mobile relay and then summarizes the related key technologies.
