Method, Apparatus and System for Forming Time Division Duplex Multi-Input Multi-Output Downlink Beams |
摘要 |
In a method for forming TDD MIMO downlink beams, a BS receives an index of a codebook element from a mobile terminal. The codebook element refers to a codebook element whose correlation value has a greatest modulus value among correlation values that are calculated by the mobile terminal and are about correlation between the codebook element and a channel corresponding to a non-transmitting antenna of the mobile terminal. The BS calculates a channel vector corresponding to the non-transmitting antenna of the mobile terminal. The BS calculates channel vectors of the transmitting antennas of the mobile terminal, and performs SVD to determine a best transmitting precoding matrix.
