Abstract

Procédé et dispositif d’émission avec pilote commun, le procédé d’émission avec pilote commun comportant l’étape où, pour l’équipement d’utilisateur configuré avec un pilote dédié à la liaison descendante, les quatre premiers symboles de multiplexage par répartition orthogonale de la fréquence de chaque sous-trame de l’équipement d’utilisateur émettent le pilote commun. Le nombre de ports d’antenne, qui correspond au pilote commun, est le nombre maximal de ports d’antenne configuré par la station de base.
