摘　　要：无线中继是一种接收其他站点无线信号,并根据接收到的信号生成自身发射信号的装置,下一代移动通信系统中会大量运用一种decode-forward模式的无线中继。这种中继本身有相对简单的协议栈,对接收信号进行解调和基带处理,然后生成发射信号。根据中继协议栈的完备程度,这种中继可以完成差错控制、功率调整、信道测量、干扰协调,甚至有调度功能。本文主要介绍无线中继对移动通信系统的影响、应用场景、相关技术,标准化组织和研究组织对其研究的进展。Wireless relay is a kind of device that receives signals from other station and generate own signals accordingly. In the next generation mobile communication system, a so called decode-forward wireless relay will be deployed. This kind of relay has simplified protocol stacks and can decode received signal. After base-band processing, it generate new version of signal for transmitting. According to complexity of protocol stacks, this kind of relay can perform error control, power control, channel measure, interference mitigation and even handover. This paper introduce wireless relay impact on communication system, deployment scenarios, related techniques and progress of related standardization and research.
