Abstract

La présente invention concerne un procédé d'attribution de porteuses, une station de base, un équipement d'utilisateur et un support de stockage lisible par ordinateur. Le procédé d'attribution de porteuses comprend : la réception d'informations de configuration de porteuses émises par une station de base, les informations de configuration de porteuses comprenant un ensemble de porteuses fixes, correspondant à chaque niveau de couverture, et un ensemble de porteuses variables ; la réception d'informations de mise à jour de porteuses émises par la station de base, les informations de mise à jour de porteuses étant générées par la station de base après une mise à jour, lorsque cette dernière détecte qu'une condition prédéfinie est satisfaite, d'un élément de porteuse variable attribué à l'ensemble de porteuses fixes ; et selon les informations de mise à jour de porteuses, l'acquisition de l'élément de porteuse variable mis à jour dans l'ensemble de porteuses fixes. La solution permet d'ajuster un élément de porteuse variable dans un ensemble de porteuses fixes dans un niveau de couverture, ce qui permet de réaliser le placement d'une pluralité d'équipements d'utilisateur.
