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 well. Key words: network planning target, common reference signal received power, common reference signal interference noise ratio, UL/DL subframe configuration 式，如随机序列加扰、跳频传输、功率控制及干扰抑制技术 1 引言
