Abstract:
A precoding matrix set determining method and apparatus, and a parameter indication information sending method and apparatus are provided. The precoding matrix set determining method include: determining, by a first network device, a parameter used for determining a precoding matrix set, where the parameter includes at least one of a phase parameter, an amplitude parameter, a quantity of vectors in the precoding matrix set, a quantity of vectors in a first codebook set in dual-codebook feedback, and a quantity of vectors in a second codebook set in the dual-codebook feedback, and the parameter is not fixed; and using the parameter to determine the precoding matrix set, where the precoding matrix set includes at least one precoding matrix. By using this solution, flexibility of feeding back a precoding matrix indicator is improved.

Claim (Index 18):
The apparatus according to  claim 13 , wherein the parameter comprises at least one of a first phase value \u03c6 1 , a phase interval \u0394, the quantity N of vectors in the precoding matrix set, and a quantity M of elements in each vector in the precoding matrix set, and others, except the parameter, in the first phase value \u03c6 1 , the phase interval \u0394, the quantity N of vectors in the precoding matrix set, and the quantity M of elements in each vector in the precoding matrix set are preset; and\n the set determining unit is specifically configured to determine, by using a phase range [0,\u03c6 1 ], the phase interval \u0394, the quantity N, and the quantity M, a vector that forms the precoding matrix set; wherein 0 is a minimum value of a phase difference between two adjacent antennas in a vector in the precoding matrix set; and the first phase value \u03c6 1  is a maximum value of the phase difference between two adjacent antennas in the vector in the precoding matrix set.
