Channel information transmission method, data transmission method and equipment to improve the feedback accuracy of precoding matrix. A first device includes: a receiving module for receiving a reference signal, a processing module for measuring the reference signal to obtain the first channel information and the second channel information; a transmitting module for transmitting the first channel information and the second channel information; a first channel information includes the identification information of M first vectors, M being an integer of not less than 2; and a second channel information includes: The information of weighted merging factor of N first vectors in M first vectors is a positive integer not greater than M. The first channel information and the second channel information are used to form a precoding matrix. When the second device generates the precoding matrix, it can combine M first vectors according to the weighted merging factor indicated by the received second channel information, instead of selecting only one eigenvector from multiple eigenvectors, so the precoding matrix generated is more accurate.
