METHODS AND APPARATUSES FOR TRANSMITTING CODING INDICATION INFORMATION AND DETERMINING PRECODING MATRIX |
摘要 |
Disclosed are methods and apparatuses for transmitting coding indication information and determining a precoding matrix, for use in resolving the problem that the resolution of code words in a codebook generated by using a combination of a beam vector subgroup and column selection cannot be flexibly adjusted. The method comprises: user equipment determines first precoding indication information and second precoding indication information, the first precoding indication information corresponding to a first-stage precoding matrix, the first-stage precoding matrix comprising beam vectors in different polarization directions, the second precoding indication information corresponding to a second-stage precoding matrix, the second-stage precoding matrix being used for performing amplitude weighting and phase adjusting on all beam vectors in each polarization direction in the first-stage precoding matrix, and the first-stage precoding matrix and the second-stage precoding matrix being used for generating a precoding matrix. Amplitude weighting and phase adjusting are performed on all beam vectors in each polarization direction in a first-stage precoding matrix, so that the resolution of a precoding matrix is flexibly adjusted, and the system performance is improved. |
