Abstract

La présente invention utilise des ressources spécifiques à un utilisateur, telles qu'allouées sur la liaison montante, pour transporter un ou plusieurs signaux de référence de sondage (SRS) spécifiques à une antenne. Cette technique permet par exemple à un équipement d'utilisateur (UE) configuré pour un fonctionnement de liaison montante en mode entrée multiple/sortie multiple (MIMO) d'envoyer de façon avantageuse des SRS spécifiques à une antenne dans le cadre des ressources accordées allouées à l'UE via un ou plusieurs octrois de liaison montante programmés. Ainsi, à l'intérieur des ressources accordées allouées par un octroi de liaison montante donné, un UE utilise au moins une partie de ces ressources pour envoyer des SRS spécifiques à une antenne plutôt que pour envoyer des données de liaison montante (trafic utilisateur). La présente invention comprend donc, dans un ou plusieurs modes de réalisation, un procédé, au niveau de l'UE, de transmission de SRS spécifiques à une antenne pour deux antennes d'émission de liaison montante ou plus. Le procédé comprend la transmission d'un signal de référence de sondage spécifique à une antenne pour au moins une des antennes d'émission de liaison montante à l'intérieur d'une ressource accordée allouée à l'équipement d'utilisateur pour une transmission de données de liaison montante programmée.
