摘　　要：中继技术在LTE-Advanced系统设计中得到了极大的关注。首先介绍了转发协议层面的中继定义和实现策略层面的定义。此后,对比TypeⅠ中继和Type Ⅱ中继发现,Type Ⅱ中继可以同基站实现更好的协作功能。文中介绍了一种协作的Type Ⅱ中继系统实现方案。最后,总结了Type Ⅱ中继在今后发展中将面临的挑战。Relay technology has been great concerned in LTE-Advanced system.Firstly,we introduce the definition of relay in respective of protocol level and implementation strategic level.By comparing Type Ⅰ and Type Ⅱ relay,we find that Type Ⅱ relay can achieve better performance in collaboration with base station.Then,we introduce a scheme of collaborative Type Ⅱ system.Finally,this article summarizes some challenges of Type Ⅱ relay in future development.
