CHANNEL STATUS INFORMATION FEEDBACK AND CONTROL METHOD AND DEVICE
First Claim
1. A method for feeding back channel state information, the method comprising:
- receiving, by a user equipment, a trigger signaling transmitted by a base station, wherein the trigger signaling is configured to indicate the user equipment to report Channel State Information (CSI) obtained in a specified measurement window; and
reporting, by the user equipment, the CSI measured by the user equipment in the measurement window to the base station.

Abstract
Disclosed are a channel status information (CSI) feedback and control method and device. The method comprises: a terminal receives trigger signaling sent by a base station, the trigger signaling being used for instructing the terminal to report CSI obtained within a specified measurement window; and the terminal reports the CSI that is measured by the terminal within the specified measurement window to the base station. Because a terminal reports only CSI that is measured by the terminal within a specified measurement window, the frequency of feeding back CSI by the terminal is reduced, and CSI feedback overheads are also reduced.
