Abstract
Official abstract text for this publication.
The invention relates to a technical field of multiple-antenna transmission in a wireless communication system. Communication of feedback representation of and generating a codebook suitable for precoding of multiple-antenna transmission is disclosed. An example matrix representation of precoding of a first number of antenna ports comprises precoding sub-matrices of less antenna ports.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of generating a first codebook A for M′ transmit antenna ports, of multiple-antenna communication in a wireless communication system, comprising at least a first precoding matrix a p , said first precoding matrix a p having M′ rows and R′ columns, where M′ and R′ are natural numbers and comprising at least a first and second sub-matrix having M rows and R 1 columns, wherein a first sub-matrix is located at rows m=1 . . . M and columns r=1,2,…
