Patent ID: 10516450

Abstract:
A method, system, and device for transmitting coding instruction information, for use in solving the problem as current codebooks are designed for horizontal beamforming/pre-coding, direct application of the codebooks to a three-dimensional beamforming/pre-coding technology causes performance degradation. The method of embodiments of the present invention comprises: a user equipment determines and transmits to a network side first pre-coding instruction information and second pre-coding instruction information, where a first component pre-coding matrix is a block diagonal matrix, a submatrix on the diagonal is equal to the Kronecker product of two matrices, a second component pre-coding matrix is constituted by a weighted column selection vector, with the exception of a P-number of nonzero elements, the remainder of the weighted column selection vector is all zeros, and P is a positive integer. Employment of the method of the embodiments of the present invention increases the performance of the three-dimensional beamforming/pre-coding technology.
