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 2):
The user equipment according to  claim 1 , wherein:\n the CSI of each of the M CSI-RS resources comprises: a rank indication (RI), a first precoding matrix indicator (PMI 1) corresponding to a first codeword (W1), a second precoding matrix indicator (PMI 2) corresponding to a second codeword (W2), and a channel quality indicator (CQI), wherein the W1 and the W2 correspond, respectively, to a W1 and a W2 in a double codebook structure W, and W=W1*W2; and the transmitter is configured to feed back the CSI of the M CSI-RS resources and the indication information of the M CSI-RS resources to the base station according to a feedback mode and a feedback type, wherein the feedback type refers to a feedback parameter fed back by the user equipment at a time at a feedback moment, and the feedback parameter comprises at least one of the RI, the PMI 1, the PMI 2, the CQI, or the indication information.
