Abstract
Official abstract text for this publication.
In a codebook-based closed loop type MIMO, improvement for complexity in a mobile station apparatus, and reduction of amount of overhead needed for notification from the mobile station apparatus should be provided. A wireless transmission apparatus that includes a plurality of transmission antennas, performs precoding on a data signal for each of a plurality of reception apparatuses and spatially multiplexes and transmits the signal after the precoding. The wireless transmission apparatus performs sharing a codebook describing a plurality of linear filters associated with each other is shared with the each reception apparatus, and precoding on the data signal for each reception apparatus, based on a first linear filter that is extracted from the codebook in each reception apparatus based on the association and that is notified from each reception apparatus.
First claim
Opening claim text (preview).
