Abstract:
A channel information sending method, a data sending method, and a device are provided, to improve feedback precision of a precoding matrix. A first device includes: a receiving module, configured to receive a reference signal; a processing module, configured to measure the reference signal to obtain first channel information and second channel information; and a sending module, configured to send the first channel information and the second channel information. When generating the precoding matrix, the second device may perform weighted combination on M first vectors based on the weighted combination factor indicated by the received second channel information, instead of selecting only one eigenvector from a plurality of eigenvectors, so that the generated precoding matrix is more precise.

Claim (Index 13):
A channel information sending method, comprising:\n receiving a reference signal sent by a second device, wherein the reference signal is sent on S antenna ports, the S antenna ports belong to H reference signal resource port groups, and S and H are integers greater than or equal to 1; measuring the reference signal to obtain first channel information and second channel information; and sending the first channel information and the second channel information to the second device, wherein the first channel information comprises identification information of M first vectors, wherein M is an integer not less than 2, the second channel information comprises information about a weighted combination factor used for performing weighted combination on N first vectors in the M first vectors, wherein N is a positive integer not greater than M, the weighted combination factor comprises at least one of following factors: a first factor and a second factor, the first factor is an amplitude factor, and the second factor is a phase factor, the first channel information and the second channel information are used to constitute a precoding matrix, and a dimension of the first vector is a quantity of antenna ports in each reference signal resource port group, or a dimension of the first vector is half of a quantity of antenna ports in each reference signal resource port group.
