Abstract:
Methods and apparatuses for transmitting coding indication information and determining a precoding matrix, for use in resolving the problem that the resolution of code words in a codebook generated by using a combination of a beam vector subgroup and column selection cannot be flexibly adjusted. The method comprises: determining first precoding indication information and second precoding indication information, the first precoding indication information corresponding to a first-stage precoding matrix, the second precoding indication information corresponding to a direction weighting vector and a phase adjustment factor, the direction weighting vector being used for performing interpolation processing on parts representing angles corresponding to beam vectors in the all beam vectors in each polarization direction in the first-stage precoding matrix, the phase adjusting factor being used for performing phase adjustment on different polarization directions of the first-stage precoding matrix, and the first-stage precoding matrix, the direction weighting vector, and the phase adjustment factor being used for generating a precoding matrix. The resolution of a precoding matrix is flexibly adjusted by using a direction weighting vector.

Claim (Index 5):
A method for determining a pre-coding matrix, the method comprising:\n receiving, by the network side, first pre-coding indication information and second pre-coding indication information transmitted by a User Equipment, UE; and determining, by the network side, a pre-coding matrix from the first pre-coding indication information and the second pre-coding indication information; wherein the first pre-coding indication information corresponds to a first level of pre-coding matrix, the second pre-coding indication information corresponds to direction weighting vectors and phase adjusting factors, the direction weighting vectors are used for interpolation on such components of respective beam vectors in each polarization direction in the first level of pre-coding matrix that represent angles corresponding to the beam vectors, the phase adjusting factors are used for phase adjustment on the different polarization directions of the first level of pre-coding matrix, and a pre-coding matrix is generated from the first level of pre-coding matrix, the direction weighting vector, and the phase adjusting factor.
