Patent ID: 11251845

Abstract:
A channel information sending method, a data sending method, and a device are provided, to improve feedback precision of a precoding matrix. These include a receiver that receives a reference signal and a memory, configured to store at least one computer instruction which, when executed by the processor, cause the processor to measure the reference signal from the receiver to obtain first channel information and second channel information and send the first channel information and the second channel information to the second device. In some embodiments, the first channel information comprises identification information of N antenna ports in M antenna ports for the reference signal, M is an integer not less than 2, and N is a positive integer not greater than M, the second channel information comprises information about a weighted combination factor used for performing weighted combination on the N antenna ports, the weighted combination factor comprises an amplitude factor and a phase factor, and the first channel information and the second channel information are used to constitute a precoding matrix.
