摘要 |
An apparatus and method for a precoding matrix are disclosed. A codebook used for selecting a precoding matrix is comprised of m subgroups each including n precoding matrices. A user equipment indicates a specific precoding matrix selected from the codebook by transmitting to a base station a first codebook index indicating one of the m subgroups and a second codebook index indicating one of n precoding matrices in a subgroup.
