Title:

CHANNEL STATE INFORMATION FEEDBACK METHOD AND RELATED DEVICE FOR FD MIMO SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/020749

Kind Code:

A1

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.
