Title: METHOD AND DEVICE FOR FEEDING BACK CHANNEL STATE INFORMATION
Abstract:
Embodiments of the present application provide a method for feeding back channel state information (CSI). The method is applied to a wireless communication system and comprises: a user equipment (UE) receives time configuration signaling and feedback configuration signaling, the time configuration signaling being used for setting a feedback time period, the feedback configuration signaling being used for configuring one or more feedback cycles; the UE periodically obtains and sends CSI in the one or more cycles within the feedback time period. The provided method for periodically feeding back CSI within a feedback time period can reduce system overheads by means of the automatic feedback of a UE.
