摘要:
The present invention provides a method and device for obtaining precoding matrix. A network apparatus comprises a plurality of groups of cross-polarized linear array antennas. The method comprises: obtaining first channel indicating information indicating a first code word; obtaining second channel indicating information indicating a second code word; determining the precoding matrix, according to the first channel indicating information and the second channel indicating information, the first code word and/or the second code word comprises phase shifts and/or amplitude differences among the plurality of groups of cross-polarized linear array antennas. Since the first code word and the second code word for determining the precoding matrix by the network apparatus comprise phase shifts and amplitude differences among cross-polarized linear array antennas, the phase shifts and amplitude differences among cross-polarized linear array antennas are considered when the network apparatus sends downlink data according to the precoding matrix, so as to be able to improve the receiving quality of the sent data, thereby improving the system performance effectively.
摘要(中):
本发明提供一种获取预编码矩阵的方法和装置。 网络装置包括多组交叉极化线性阵列天线。 该方法包括:获得指示第一码字的第一信道指示信息; 指示第二码字的第二频道指示信息; 根据第一信道指示信息和第二信道指示信息确定预编码矩阵,第一码字和/或第二码字包括多组交叉极化线性阵列天线之间的相移和/或幅度差异 。 由于用于由网络装置确定预编码矩阵的第一码字和第二码字包括交叉极化线性阵列天线之间的相移和幅度差,所以当交叉极化线性阵列天线的相移和幅度差异 网络设备根据预编码矩阵发送下行链路数据,从而能够提高发送数据的接收质量,从而有效提高系统性能。
