Abstract

La présente invention concerne un procédé et un dispositif pour une attribution de ressource. Le procédé comprend les opérations suivantes : une requête de ressource de canal de commande de liaison montante physique (PUCCH) est reçue par une station de base primaire (P-eNB); en réponse à la requête de ressource de PUCCH, une première ressource de PUCCH cible est sélectionnée parmi N ressources de PUCCH disponibles préconfigurées, la première ressource de PUCCH cible étant utilisée pour une rétroaction de liaison montante correspondant à des premières données de liaison descendante au niveau d'un côté station de base secondaire (S-eNB), et N étant un nombre entier positif; et un indice correspondant à la première ressource de PUCCH cible est transmis au S-eNB.
