Method for generating codebook, method and apparatus for data transmission |
摘要 |
<p>A method for generating a codebook and a method and an apparatus for data transmission are provided. The method for data transmission includes: receiving a label of a codeword in a codebook for an eight-antenna sent by a user equipment (UE); searching for the codeword identified by the label in the codebook for eight-antenna; and coding data to be sent by using the codeword, and sending the coded data. The codebook for eight-antenna includes at least one rank-8 codeword for eight-antenna. The rank-8 codeword for eight-antenna is obtained by multiplying an inverse matrix of a rotation matrix for eight-antenna with an eight-dimensional matrix formed by rank-4 codewords for four-antenna; or obtained by extending rank-4 codewords for eight-antenna, where the rank-4 codeword for eight-antenna is obtained according to codewords for four-antenna. Therefore, the codeword in the codebook for eight-antenna is applicable to scenarios including dual-polarization strong correlation, dual-polarization weak correlation, single-polarization strong correlation, and single-polarization weak correlation, etc.
