TD-SCDMA到TD-LTE平滑过渡的建设方案浅析

摘要

The evolution from TD-SCDMA to TD-LTE is briefly is introduced and the common platform scheme of TD-SCDMA and TD-LTE is analyzed. It is concluded that the smooth transition of TD-LTE base station (BS) is mainly based on the original TD-SCDMA BS. The evolution of BBU, RRU, antenna and other devices in TDS/TDL dual mode BS is described. Finally, some details in smooth transition are expounded.%对TD-SCDMA向TD-LTE演进进行了简要概述，并分析了TD-SCDMA与TD-LTE共平台方案，得出TD-LTE基站的平滑过渡主要是基于原有TD-SCDMA基站进行的结论，描述了从BBU、RRU、天线等设备上到TDS/TDL双模基站的演进，最后还阐述了平滑过渡中需要注意的问题。
