摘要：
公共参考信号接收功率和公共参考信号干扰噪声比是TD-LTE无线网络规划的两个重要指标，与室内深度覆盖和边缘速率要求直接相关，同时TD-LTE是TDD系统，具有灵活的子帧配比方式，以适应不同的上下行业务速率需求。就TD-LTE同频组网情况下的参考信号接收功率和信号干扰噪声比这两个规划指标需要考虑的因素及两者之间的关系展开分析，并对TD-LTE的子帧结构进行分析，给出了不同频段的子帧配置建议。
关键词: 网络规划指标, 公共参考信号接收功率, 公共参考信号干扰噪声比, 上下行子帧配比
Abstract:
Common reference signal received power（CRS RSRP）and signal interference noise ratio（CRS SINR）are two important wireless network planning factors，which are directly related to indoor deep coverage and edge data rate. Besides，TD-LTE has flexible UL/DL configuration for different requirements of UL/DL throughput. The influences of different planning CRS RSRP and SINR targets on network performance and the relationship between CRS RSRP and SINR were mainly analyzed based on same frequency networking；UL/DL configuration for different bands was recommended after analyzing TD-LTE subframe structure as we11.
Key words: network planning target, common reference signal received power, common reference signal interference noise ratio, UL/DL subframe configuration
