TD-LTE系统可在TM7单流模式及TM8双流模式的基础上进一步引入增强的多天线技术,包括上行MU-MIMO和下行MU-MIMO算法。MU-MIMO算法将空间隔离度较好的一对用户进行配对,使两用户采用同一时频资源进行上行或下行传输,从而大幅提升上行或下行可用资源数量,提高双终端或小区的吞吐量性能。详细结合目前TD-LTE 上行和下行MU-MIMO 的设备实现,分析上行及下行MU-MIMO 算法在外场测试的性能表现。
Based on TM7 single-stream and TM8 dua1-stream transmission mode,multiple antenna enhancement technology can be introduced in TD-LTE system,including uplink MU-MIMO and downlink MU-MIMO. In MU-MIMO algorithm,two terminals with space division can be paired to share the same downlink resource blocks for uplink or downlink transmission. Due to the multiplexing of time-frequency resource,the valid transmission resource can be increased remarkably,thus the gain on dua1-terminal throughput and the cell overall throughput performance can be obtained. Detailed analysis on field test of uplink and downlink MU-MIMO was given,based on the algorithm implement of TD-LTE network equipment vendors.
