1. An information feedback method which is applicable to a first communication node, comprising:
receiving a downlink data transmission instruction sent by a second communication node; and
triggering, according to the downlink data transmission instruction, the first communication node to feed back demodulation capability information and channel state information (CSI) to the second communication node;
the CSI comprising: a signal-to-noise ratio (SNR) and an SNR change rate of a received signal; and
the demodulation capability information refers to the SNR corresponding to a block error rate (BLER) reaching a preset value, each time the first communication node checks data scheduled by using a Modulation and Coding Scheme (MCS).
