METHOD AND DEVICE FOR GENERATING PRECODING MATRIX CODEBOOK AND METHOD FOR DESIGNATING PRECODING MATRIX |
摘要 |
The present invention discloses a method and device for generating precoding matrix codebook and a method for a base station designating precoding matrix in multi-antenna communication system. The method for generating a precoding matrix codebook includes the following steps: the step of obtaining a selection probability: obtaining a selection probability allowed for each Rank by the multi-antenna communication system in the case of a certain Signal Noise Ratio (SNR); the step of determining a codebook size: determining a precoding matrix codebook size for a corresponding Rank according to the selection probability for each Rank in the case of the certain SNR; and the step of determining a codebook: determining a precoding matrix codebook for each Rank from the precoding matrix complete set according to the codebook size for each Rank in the case of the certain SNR.
