Abstract
Provided are a method and apparatus for transmitting and receiving channel state information, a communication node, and a storage medium. A CSI matrix H is decomposed to obtain a vector group, where the vector group comprises at least two vector matrices, element information of at least one vector matrix in the vector group is quantized, and the quantized element information is transmitted.
Claims47
A method for transmitting channel state information (CSI), comprising:
- decomposing, by a first communication node, a CSI matrix H to obtain a vector group, wherein the vector group comprises at least two vector matrices;
- quantizing element information of at least one vector matrix in the vector group;
- and
- transmitting the quantized element information.

A method for receiving channel state information (CSI), comprising:
- receiving, by a second communication node, quantized element information, wherein the element information is information corresponding to an element in at least one vector matrix in a vector group obtained by decomposing by a first communication node a CSI matrix H, and the vector group comprises at least two vector matrices;
- and
- restoring the quantized element information to obtain the CSI matrix H.
