Abstract:
A method, system and apparatus for realizing FD_MIMO in codebook-based transmissions. The method, system and apparatus include the combing of one or more horizontal codebooks and one or more vertical codebooks. A 2D beamformer for downlink transmissions is generated based on the combination of the one or more horizontal codebooks and one or more vertical codebooks.
