Abstract:
Embodiments of the present disclosure provide a channel state information feedback method, which includes: determining, by user equipment, N CSI-RS resources according to a quantity N, configured by a base station, of CSI-RS resources that need to be fed back; performing channel estimation on a port included in the N CSI-RS resources, to obtain channel state information in a horizontal dimension; then selecting M CSI-RS resources from the N CSI-RS resources; and feeding back channel state information of the M CSI-RS resources in the horizontal dimension and indication information of the M CSI-RS resources to the base station, so that the base station determines channel state information in a vertical dimension according to the indication information, so as to finally obtain channel state information in the two dimensions, thereby resolving a problem that channel state information in only a horizontal dimension is fed back during conventional channel estimation.

Claim (Index 14):
The base station according to  claim 9 , wherein:\n M\u22652; the PMIs 1 obtained by measurement according to the M CSI-RS resources are the same, and PMIs 2 obtained by measurement according to the CSI-RS resources are the same or different, a precoding matrix corresponding to the PMI 1 and the PMI 2 is obtained by measurement according to each CSI-RS resource, and an antenna quantity corresponding to the precoding matrix is a quantity of antenna ports comprised in each CSI-RS resource; the feedback mode is a second feedback mode; the feedback type comprises an eleventh feedback type, a twelfth feedback type, and a thirteenth feedback type; the eleventh feedback type corresponds to an eleventh feedback period, the twelfth feedback type corresponds to a twelfth feedback period, and the thirteenth feedback type corresponds to a thirteenth feedback period; and a feedback parameter of the eleventh feedback type comprises RIs obtained by measurement according to the M CSI-RS resources, a feedback parameter of the twelfth feedback type comprises the indication information and the PMIs 1 of the M CSI-RS resources, and a feedback parameter of the thirteenth feedback type comprises the PMIs 2 and CQIs that are obtained by measurement according to the M CSI-RS resources, wherein a quantity of the PMIs 1 is 1, and when the PMIs 2 obtained by measurement according to the CSI-RS resources are the same, a quantity of the PMIs 2 is 1, or when the PMIs 2 obtained by measurement according to the CSI-RS resources are different, the PMIs 2 are M PMIs 2.
