Information transmission method, device, and storage medium

An information transmission method, applied to a second communication node, comprising:

• determining configuration information;
• sending the configuration information to a first communication node to enable the first communication node to report channel state information according to the configuration information;
• and
• receiving the channel state information reported by the first communication node;
• wherein the channel state information comprises a precoding matrix indicator, and the precoding matrix indicator comprises a strongest coefficient indicator;
• wherein 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, and the strongest coefficient indicator is used to indicate index of a strongest coefficient in the first coefficients, wherein the strongest coefficient refers to a coefficient having a maximum amplitude in the first coefficients;
• and
• wherein the channel state information further comprises a first number indicator, wherein the first number indicator is used to indicate a number K of coefficients whose values are not 0 in the first coefficients, and the first number indicator is reported by a field formed by A bits, and K denotes a value of the first number indicator plus 1, wherein the value of the first number indicator is a value of the field formed by the A bits, and A is a non-negative integer.

A non-transitory storage medium storing a computer program which, when executed by a processor, causes the processor to perform an information transmission method, wherein the method comprises:

• receiving configuration information from a second communication node;
• and
• reporting channel state information to the second communication node according to the configuration information;
• wherein the channel state information comprises a precoding matrix indicator, and the precoding matrix indicator comprises a strongest coefficient indicator;
• wherein 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, and the strongest coefficient indicator is used to indicate an index of a strongest coefficient in the first coefficients, wherein the strongest coefficient refers to a coefficient having a maximum amplitude in the first coefficients;
• and
• wherein the channel state information further comprises a first number indicator, wherein the first number indicator is used to indicate a number K of coefficients whose values are not 0 in the first coefficients, and the first number indicator is reported by a field formed by A bits, and K denotes a value of the first number indicator plus 1, wherein the value of the first number indicator is a value of the field formed by the A bits, and A is a non-negative integer.
