Abstract

La présente invention concerne des procédés, des systèmes et des dispositifs destinés à des communications sans fil. Un équipement d'utilisateur (UE) peut recevoir, d'une entité de réseau, des informations de commande qui indiquent un indice de précodage associé à une matrice de précodage à utiliser par l'entité de réseau dans la transmission d'un message de liaison montante selon un rang de précodage. L'UE peut identifier, sur la base de l'indice de précodage, la matrice de précodage dans une structure de données particulière incluant un sous-ensemble particulier de matrices de précodage, et le sous-ensemble particulier de matrices de précodage peut avoir moins qu'un nombre total de matrices de précodage associées au rang de précodage et à un nombre d'antennes. Chaque matrice de précodage du sous-ensemble particulier est associée à une combinaison respective d'antennes de l'entité de réseau, et chaque combinaison respective d'antennes est configurée pour atténuer un emplacement d'antenne partielle respectif. L'UE peut également transmettre le message de liaison montante précodé selon la matrice de précodage identifiée.
