阅读说明：本技术 一种信道估计方法和装置 (Channel estimation method and device ) 是由 王潇涵 金黄平 任翔 韩玮 毕晓艳 于 2019-01-08 设计创作，主要内容包括：本申请实施例公开了一种信道估计方法和装置,涉及通信技术领域,有助于降低指示开销。该方法可以包括：生成并发送指示信息,指示信息用于指示M个N维预编码向量,每个预编码向量应用于M个频带中的一个频带,M个N维预编码向量构成一个空频矩阵,空频矩阵由多个空频分量矩阵加权合并生成；空频矩阵是一个M×N维空频向量或者X×Y的空频矩阵,其中X和Y分别为M和N之中的一个和另一个,M≥1,N≥2,M和N均是整数。(The embodiment of the application discloses a channel estimation method and a channel estimation device, relates to the technical field of communication, and is beneficial to reducing indication overhead. The method can comprise the following steps: generating and sending indication information, wherein the indication information is used for indicating M N-dimensional precoding vectors, each precoding vector is applied to one frequency band of the M frequency bands, the M N-dimensional precoding vectors form a space-frequency matrix, and the space-frequency matrix is generated by weighting and combining a plurality of space-frequency component matrixes; the space-frequency matrix is an M multiplied by N dimensional space-frequency vector or an X multiplied by Y space-frequency matrix, wherein X and Y are respectively one and the other of M and N, M is more than or equal to 1, N is more than or equal to 2, and M and N are integers.)
