Patent

CA 2755399

A method for transmitting and receiving uplink signals using an optimized rank 3 codebook is disclosed. The opti-mized rank 3 codebook includes 6 precoding matrix groups, each of which has 1 variable having an amplitude of 1. Preferably, the optimized 4Tx rank 3 codebook has 12 precoding matrix, two precoding matrixes are selected from each the above 6 precoding matrix groups considering chordal distance and the number of precoding matrix.

L'invention concerne un procédé d'émission et de réception de signaux montants en utilisant un livre de code de rang 3 optimisé. Le livre de code de rang 3 optimisé comprend 6 groupes de matrices de précodage dont chacune contient une variable ayant une amplitude égale à 1. De préférence, le livre de code de rang 3 optimisé de type 4Tx comporte 12 matrices de précodage, deux matrices de précodage sont sélectionnées parmi chacun des 6 groupes de matrices de précodage mentionnés ci-dessus en tenant compte de la distance à la corde et du nombre de matrices de précodage.
