阅读说明：本技术 预编码矩阵的指示方法、通信装置及存储介质 (Method for indicating precoding matrix, communication device and storage medium ) 是由 张瑞齐 李雪茹 于 2018-09-28 设计创作，主要内容包括：本申请实施例提供一种预编码矩阵的指示方法、通信装置及存储介质,K个频域单元的每个频域单元的预编码矩阵满足W＝W-1×W-2,将K个频域单元上的W-2中的元素用较少的P个元素表征。终端设备上报第三指示信息,所述第三指示信息包括第一指示信息和所述第二指示信息,所述第一指示信息和第二指示信息独立编码,其中所述第一指示信息用于指示P个元素,所述第二指示信息用于指示P。从而所述终端设备可以根据信道条件变化而调整第二指示信息的信息比特个数,提高预编码矩阵上报的效率。(An embodiment of the present application provides an indication method of a precoding matrix, a communication device, and a storage medium, where a precoding matrix of each of K frequency domain units satisfies W ═ W 1 ×W 2 W over K frequency domain units 2 Is characterized by fewer P elements. And the terminal equipment reports third indication information, wherein the third indication information comprises first indication information and second indication information, and the first indication information and the second indication information are independently coded, the first indication information is used for indicating P elements, and the second indication information is used for indicating P. Therefore, the terminal equipment can adjust the number of information bits of the second indication information according to the change of the channel condition, and the reporting efficiency of the precoding matrix is improved.)
