Abstract:
This application discloses a precoding information sending solution and a precoding information feedback solution. A base station generates a signaling indicator and sends the signaling indicator to user equipment. The signaling indicator indicates related information about a precoding matrix set determined by the base station from a stored codebook, where the precoding matrix set belongs to a subset of the stored codebook. The user equipment selects a precoding matrix according to the signaling indicator sent by the base station, and sends a precoding matrix indicator PMI to the base station. The precoding matrix is selected according to a precoding matrix set and a feedback is performed. Therefore, complexity of searching for the precoding matrix and precoding feedback bits may be reduced.

Claim (Index 14):
The method according to  claim 13 , wherein the set of W 2  codewords in the precoding matrix set comprises one of the following:\n at least one W 2  codeword whose column selection vector value is a subset of column selection vector values of the W 2  codewords in the at least one codebook, at least one W 2  codeword whose phase rotation weighting factor value is a subset of phase rotation weighting factor values of the codewords W 2  in the at least one codebook , or at least one W 2  codeword whose column selection vector value and phase rotation weighting factor value are subsets of column selection vector values and phase rotation weighting factor values of the W 2  codewords in the at least one codebook.
