Title:

INFORMATION FEEDBACK METHOD AND DEVICE, AND COMMUNICATION NODE AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2021/232890

Kind Code:

A1

Abstract:

Disclosed are an information feedback method and device, and a communication node and a storage medium. The information feedback method comprises: receiving a downlink data sending instruction sent by a second communication node; and triggering a first communication node to feed back demodulation capability information and CSI to the second communication node according to the downlink data sending instruction, the CSI comprising an SNR of a receiving signal and an SNR change rate.
