Methods, apparatuses, and systems for performing analog CSI feedback
The present disclosure discloses a method for performing analog CSI feedback in a user equipment, comprising: a. obtaining an analog CSI matrix corresponding to the user equipment, the analog CSI matrix satisfies a condition below: X XH=D, where X denotes the analog CSI matrix, H denotes conjugate transpose of matrix, and D denotes a diagonal matrix; b. obtaining dominated element information corresponding to the analog CSI matrix according to predetermined index information, and transmitting the dominated element information to a base station. The solution according to the present disclosure can reduce feedback overheads to a greater extent, has a high CSI feedback quality, and can reliably implement CSI recovery at the base station side.
