Abstract: A method for correcting indication information is described; the method includes that: a Signal-to-Noise Ratio (SNR) value of a first layer at current time and an SNR value of a second layer at the current time are obtained; a channel correlation value at the current time is calculated according to the SNR value of the first layer and the SNR value of the second layer; a smoothing value of the channel correlation value at the current time is calculated according to the calculated channel correlation value and a preset forgetting factor; and a Rank Indicator (RI) value and/or a Channel Quality Indicator (CQI) value are/is corrected according to the obtained smoothing value. A system and a storage medium for correcting indication information are also described.
