Abstract

The invention provides a CSI feedback configuration method, a network side device, and a terminal. The method comprises the following steps: the network side device sends indication information to theterminal through first signaling, wherein the indication information is used for indicating the terminal to obtain feedback configuration, and the feedback configuration is used for indicating the CSI that needs to be fed back by the terminal; and the network side device receives the CSI fed back by the terminal according to the feedback configuration. In this way, the terminal can feed back theCSI according to the feedback configuration configured by the network side device, so that the accuracy of the CSI feedback can be improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a channel state information (Channel State Information, CSI) feedback configuration method, network side equipment and terminal. Background technique [0002] In order to improve the communication performance in the communication system, the terminal often feeds back CSI to the network side device, which can allow the network side device to perform corresponding data transmission processing based on the CSI fed back by the terminal. However, the current way for the terminal to feed back CSI to the network side device is fixed, which leads to poor accuracy of CSI feedback. Summary of the invention [0003] The purpose of the present invention is to provide a CSI feedback configuration method, network side equipment and terminal to solve the problem of poor accuracy of CSI feedback. [0004] In order to achieve the foregoing objective, an embodiment of the present invention...
