摘要

TD-LTE主要部署在高频段，传播损耗和穿透损耗较大，给未来网络室内深度覆盖带来严峻的挑战。在明确TD-LTE室外覆盖室内部署需求的基础上，结合现网测试验证，对中继（relay）增强室内覆盖的性能进行了深入分析。结果表明，针对一些暂时不具备有线回传条件的楼宇，引入中继并以室外覆盖室内方式进行部署，可提供快速、灵活、低成本的深度覆盖解决方案。

Abstract

TD-LTE will be deployed on high frequency band，facing with the issue of larger propagation loss and penetration loss，which brings a big challenge to future indoor deep coverage. Based on clarifying the requirement of TD-LTE outdoor to indoor deployment，and also combined with the field trial in the real network，the performance of indoor coverage enhancement using relay was analyzed. Test results show that deploying relay outside buildings and enhancing the deep coverage from outdoor to indoor is a fast，flexible and low cost solution for the buildings without the wired backhau1.
