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 8):
A base station, comprising:\n a receiver configured to receive channel state information (CSI) of M CSI-RS resources and indication information of the M CSI-RS resources that are fed back by user equipment (UE), wherein the M CSI-RS resources are selected by the UE from N CSI-RS resources, the N CSI-RS resources are configured by the base station and received by the UE, the CSI-RS resources comprise at least one port, N\u22652, and N is an integer; and a processor configured to perform precoding according to the M CSI-RS resources.
