摘要
3GPP Release 10标准引入中继的目标是通过在存在覆盖问题的区域内增加新节点,来改善LTE网络性能,它可用于在难于实现有线回程的区域构建LTE网络。文章给出了作为直接链路质量函数的中继性能,分析了3GPP Release 10中继的设计原理,描述了中继节点链路设计流程,最后介绍了中继部署的典型场景。
The objective of relaying in 3GPP Release 10 is to improve performance of the LTE network by adding new nodes in areas where there are coverage problems.Relays can be used to build LTE network to areas where it is hard to get wire line backhaul.This paper presents the relay performance as function of direct link quality,analyzes the architecture and design principles of Release 10 relays and describes the link design procedures of relay nodes.In conclusion,we introduce the typical scenarios of relay deployment.
