Abstract: Provided are an information transmission method, a device and a storage medium. The information transmission method applied to a first communication node includes: receiving configuration information of a second communication node and reporting channel state information to the second communication node according to the configuration information. The channel state information includes a precoding matrix indicator, and the precoding matrix indicator includes a strongest coefficient indicator. A precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors, or a precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors and a second group of vectors. The strongest coefficient indicator is used to indicate index of a strongest coefficient in the first coefficients.
