阅读说明：本技术 利用非对称发射和接收天线的经预编码探通参考信号传输 (Precoded sounding reference signal transmission with asymmetric transmit and receive antennas ) 是由 S·A·A·法科里安 X·张 T·刘 于 2018-04-18 设计创作，主要内容包括：描述了用于无线通信的方法、系统和设备。用户装备(UE)可以获得关于UE的多个天线的干扰和噪声协方差矩阵。UE可以基于该干扰和噪声协方差矩阵和该多个天线中与该UE处的传送操作相关联的天线数目来生成近似协方差矩阵。与UE处的传送操作相关联的天线数目可少于天线总数。UE可以使用近似协方差矩阵对探通参考信号(SRS)进行预编码,并使用与传送操作相关联的天线来传送经预编码SRS。(Methods, systems, and devices for wireless communication are described. A User Equipment (UE) may obtain interference and noise covariance matrices for multiple antennas of the UE. The UE may generate an approximate covariance matrix based on the interference and noise covariance matrix and a number of antennas of the plurality of antennas associated with a transmit operation at the UE. The number of antennas associated with a transmit operation at the UE may be less than the total number of antennas. The UE may precode a Sounding Reference Signal (SRS) using the approximate covariance matrix and transmit the precoded SRS using antennas associated with the transmit operation.)
