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 25):
The terminal according to  claim 17 , wherein the processor is configured:\n if the configuration information comprises the codebook indication information, to determine a codebook to be used in calculating CSI during CSI measurement, according to the codebook indication information; wherein the processor configured to determine a codebook to be used in calculating CSI during CSI measurement, according to the codebook indication information is further configured:\n to determine a codebook in a set of preset codebooks, an index of which is the codebook indication information, and to take the determined codebook as the codebook to be used in calculating CSI; \n or \n to determine a subset of a preset codebook according to values of respective bits in the codebook indication information, and to take the determined subset as the codebook to be used in calculating CSI, wherein each bit in the code indication information corresponds to a codeword in the preset codebook; \n or \n to obtain a generation matrix of a target codebook according to the codebook indication information, to determine the target codebook according to the generation matrix and a preset codebook, and to take the target codebook as the codebook to be used in calculating CSI; \n or \n to obtain generation parameters of a target codebook according to the codebook indication information, and to generate the target codebook according to the generation parameters of the codebook, and a preset rule; \n and/or wherein the processor is configured:\n if the configuration information comprises the codebook subset restriction indicator, to determine codewords currently available in a predefined codebook according to the codebook subset restriction indicator.
