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 2):
The method according to  claim 1 , wherein determining, by the UE, the first pre-coding indication information and the second pre-coding indication information comprises:\n selecting, by the UE, a first level of pre-coding matrix from a set of first level of pre-coding matrixes, and determining the first pre-coding indication information corresponding to the selected first level of pre-coding matrix; and selecting, by the UE, a direction weighting vector from a set of direction weighting vector, and selecting a phase adjusting factor from a set of phase adjusting factor; and determining index information of a combination of the selected direction weighting vector and the selected phase adjusting factor among all the possible combinations as the second pre-coding indication information, or determining index information of the selected phase adjusting factor in the set of phase adjusting factors, and bit information representing a value of the selected direction weighting vector as the second pre-coding indication information.
