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 1):
A first device, comprising:\n a memory, configured to store at least one computer instructions; a processor, configured to execute the instructions on the memory, to perform following operations:\n receive 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, measure the reference signal to obtain first channel information and second channel information, and send 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, 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, N is a positive integer not greater than M, the weighted combination factor comprises at least one of 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.
