Abstract

Les modes de réalisation de la présente invention présentent un procédé pour attribuer des ressources de communication, une station de base et un équipement d'utilisateur, qui concernent le domaine technique des communications. Le procédé consiste en ce que : une première station de base envoie des informations de configuration à un équipement d'utilisateur (UE), de sorte que l'UE envoie des données à la première station de base en utilisant des ressources de liaison montante conformément aux informations de configuration, et les informations de configuration sont utilisées pour indiquer qu'une ressource de liaison montante spécifique est réservée dans les ressources de liaison montante; et la première station de base envoie des informations de communication à une seconde station de base sur la ressource de liaison montante spécifique. La présente invention est appropriée pour la transmission d'informations de communication entre une pluralité de stations de base.
