Abstract:
The present invention discloses a channel state information (CSI) feedback method and related device for an FD MIMO system, and is configured to support the scenario in which various CSI related information needs to be fed back after a CSI measurement in an FD MIMO system. The method comprises: a terminal receives a CSI feedback configuration group indicated by a base station and configuration information for performing a CSI feedback based on the CSI feedback configuration group; and the terminal performs a CSI measurement and feedback according to the CSI feedback configuration group and the configuration information, wherein the CSI feedback configuration group comprises at least one CSI feedback configuration, and the CSI feedback configuration is a downlink signal configuration for a downlink CSI measurement and feedback.

Claim (Index 3):
The method according to  claim 1 , wherein the configuration information comprises any one or more of:\n transmission mode indication information, wherein the transmission mode is a beamformed CSI measurement pilot transmission mode, or a non-precoded CSI measurement pilot transmission mode; CSI feedback mode indication information, wherein the CSI feedback mode is to feed back CSI corresponding to all the CSI feedback configurations in the set of CSI feedback configurations, or to feed back positional information and CSI corresponding to the optimum CSI feedback configuration in the set of CSI feedback configurations; indication information of a downlink channel information item to be fed back over a Physical Uplink Control Channel, PUCCH; indication information of a downlink channel information item to be fed back over a Physical Uplink Shared Channel, PUSCH; codebook indication information of a codebook to be used in calculating CSI; and a codebook subset restriction indicator indicating codewords currently available in a predefined codebook to be used in calculating CSI.
