Abstract
Official abstract text for this publication.
The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting/receiving a signal by using a codebook. According to an embodiment of the present invention, the method for a transmitter supporting Nt antennas to attain the technical objects thereof and transmit a signal to a receive includes selecting the precoding matrix indicated by the combination of a first precoding matrix indicator (PMI) and a second PMI, precoding the signal by using the selected precoding matrix, and transmitting the precoded signal through the Nt antennas. Here, the first PMI may indicate one matrix group among N matrix groups (N≧1) including matrices representing channel directions related to the Nt antennas. Additionally, the precoding matrix may be selected by multiplying the one matrix group indicated by the first PMI by the matrix indicated by the second PMI.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for transmitting a signal from a transmitter, which supports Nt antennas, to a receiver, the method comprising: selecting a precoding matrix indicated by a combination of a first precoding matrix indicator (PMI) and a second PMI; precoding the signal by using the selected precoding matrix; and transmitting the precoded signal through the Nt antennas, wherein the first PMI indicates one matrix group among N matrix groups (N≧1) including m…
