摘　　要：本文首先描述了LTE-A Relay系统架构;其次,介绍Relay的分类与回传链路设计;最终,通过系统仿真方法,给出了Relay对于覆盖性能、宏基站吞吐量的提升效果,并给出了回传链路的设计建议。In the network developments, there are some areas not covered by the network due to transmission, macrostation limited or skyscrapers impediments. Relay can solve these problems. This paper described thearchitecture of Relay in LTE-A system, introduced the classifi cation of Relay and the design of back-haul,gave the performance through the system simulation and the recommendations of the back-haul design.
