Abstract
The invention claims a codebook generation method data transmission method and device; wherein said data transmission method comprises the follows: receiving label of code word transmitted by UE in 8 antenna codebook; searching code word labelled by said label in said 8 antenna codebook; coding data to be transmitted through said code word and transmitting coded data; said 8 antenna codebook at least comprises code word that 8 antenna order is 8; said code word that 8 antenna order is 8 is obtained through multiplying the reversed matrix of rotation matrix of 8 antenna with 8-dimensional matrix formed by code word that 4 antenna order is 4; or code word that 8 antenna order is 8 is obtained through expanding the code word that 8 antenna order is 4; said code word that 8 antenna order is 4 is obtained according to 4 antenna code word. The code word in 8 antenna codebook of the invention is adaptive to several kinds of dual-polarized strongly correlated dual-polarized weakly correlated single-polarized strongly correlated and single-polarized weakly correlated scenes.
