METHODS AND APPARATUSES FOR GENERATING AND FEEDING BACK HIGH RANK ADAPTIVE CODEBOOK IN MULTIPLE INPUT MULTIPLE OUTPUT SYSTEM |
摘要 |
A method and device for generating and feeding back high rank adaptive codebook in multiple input multiple output system are disclosed in the embodiments of the invention. The method for generating high rank adaptive codebook includes: using different levels of a long time channel correlation matrix to transform different row vectors in high rank basic codebook, so as to aim at the directions of different eigenvectors of the long time channel correlation matrix; and using the transformed row vectors to construct the high rank adaptive codebook. The method of the invention has well system performance gain and no any additional feedback cost.
