GENERATING A NODE-B CODEBOOK

摘要

A method and apparatus generates a codebook and associated scheduling and control signaling. A plurality of channel combinations is generated for a plurality of wireless transmit receive units (WTRUs). The channel for each WTRU is quantized based on the WTRU codebook. A codebook for beamforming is generated for a plurality of WTRUs. The codebook includes a plurality of beamforming matrices. All possible beamforming matrices may be computed and the codebook may be quantized.
