Mimo Csi(咪咪芝)研究综述
Mimo Csi 咪咪芝 - Because of this mismatch, uplink sounding reference signals (SRSs) from the UE are not enough for the BS to obtain full downlink MIMO CSI. [1] Since uplink sounding reference signals (SRSs) are transmitted from only the transmit antennas of the UE, the BS is not able to obtain full downlink MIMO CSI by using channel reciprocity for spatial multiplexing. [2] By using multipath MIMO CSI in the time domain, instead in the frequency domain, our hierarchical scheme uses coarse-to-fine process and can achieve accurate positioning, which is demonstrated by simulation results. [3]由于这种不匹配，来自 UE 的上行链路探测参考信号 (SRS) 不足以让 BS 获得完整的下行链路 MIMO CSI。 [1] 由于仅从 UE 的发射天线发送上行链路探测参考信号 (SRS)，因此 BS 无法通过使用信道互易性进行空间复用来获得完整的下行链路 MIMO CSI。 [2] 通过在时域使用多径 MIMO CSI，而不是在频域，我们的分层方案使用从粗到细的过程，可以实现精确定位，仿真结果证明了这一点。 [3]
