Abstract
Official abstract text for this publication.
A method, an apparatus and a communication unit for generating precoding feedback information in a multiple frequency radio transmission system are disclosed. A rank for precoding matrices, wherein the rank is constant over the multiple frequencies, is selected and a plurality of precoding matrices having the selected rank are selected. A different precoding matrix is selected for each frequency subset of the multiple frequencies.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method, comprising: determining a rank for a set of sub-bands; generating a rank feedback regarding the rank; selecting a sub-band precoding matrix for a sub-band from the set of the sub-bands; generating a sub-band precoding matrix index regarding the sub-band precoding matrix based on the rank that is determined for the set of sub-bands; and decoding a data stream to be transmitted based on the sub-band precoding matrix.…
