Transmission channel state sending method and device, transmission channel state receiving method and device, and storage medium

A method for receiving a channel state, comprising:

• receiving a channel state report that characterizes a channel state, wherein the channel state report indicates a precoding matrix,
• wherein the channel state report comprises two parts,
• wherein a first part of the channel state report is mapped on a first sequence,
• wherein a second part of the channel state report is mapped on a second sequence, wherein the second part comprises a plurality of fragments,
• wherein the plurality of fragments correspond to a plurality of coefficients in coefficient matrixes for the precoding matrix,
• wherein the plurality of fragments have different priorities,
• wherein a first fragment of the plurality of fragments in the second part of the channel state report has a higher priority than other fragments from the plurality of fragments sequenced after the first fragment,
• wherein a second fragment of the plurality of fragments has a higher priority than other fragments from the plurality of fragments sequenced after the second fragment,
• wherein the second fragment comprises a portion of a matrix that indicates reported coefficients in the coefficient matrixes for the precoding matrix,
• wherein the second fragment comprises a portion of the reported coefficients in the coefficient matrixes for the precoding matrix, and
• wherein the portion of the reported coefficients corresponds to the portion of the matrix.
