Abstract  Abstract

The embodiment of the invention claims a codebook generating method data transmission method and device wherein the data transmission method comprises the following steps: receiving the label in 8 antenna codebook the code word transmitted by UE in 8 antenna codebook searching for the codeword identified by the label; using said code word for encoding data to be transmitted encoded data sent by said 8 antenna codebook at least comprises code word that 8 antenna order is 8 code word the 8 antenna order is 8 using the rotation matrix of 8 antenna of inverse matrix with 4 antenna order is 8 dimensional matrix multiplication 4 of code word is obtained; Alternatively the code word of 8 antenna order is 8 is code word is formed by expansion forming rank 4 8 antenna the 8 antenna order is 4 is code word according to 4 antenna code word. Using the technical solution provided by the embodiment of the invention the code words in the 8 antenna codebook suitable for double-polarization strong correlation dual polarization weak correlation polarization strong correlation and single-polarization weak related and other scene.
