Abstract:
Disclosed are CSI feedback method, a precoding method, and an apparatus. In the present invention, after a terminal determines first precoding matrices on a first subband, the terminal obtains second precoding matrices corresponding to physical resources in the first subband according to the first precoding matrices and a column vector arrangement mode corresponding to the first precoding matrices; and then, the terminal determines CSI on a second subband according to the second precoding matrices. In the embodiment, precoding matrices are expanded according to a column vector arrangement mode, so as to obtain second precoding matrices corresponding to different physical resources; accordingly based on the second precoding matrices, CSI is measured by using the corresponding second precoding matrices on different physical resources. In the embodiment, precoding matrices are expanded according to a column vector arrangement mode, so that precoding can be performed on each data flow in transmission by using different column vectors, thereby improving the robustness of a transmission solution, and obtaining a stabler precoding gain.

Claim (Index 5):
The method according to  claim 1 , wherein the first sub-band comprises one or more PRBs; and\n the second sub-band is same as the first sub-band; or the second sub-band comprises a plurality of first sub-bands.
