Abstract

La présente invention se rapporte : à un procédé adapté pour réduire un brouillage; à un dispositif; à une station de base; et à un contrôleur de réseau sans fil. L'invention appartient au domaine technique des communications. En transmettant un premier message de configuration et un second message de configuration à un équipement d'utilisateur et à une station de base respectivement, l'équipement d'utilisateur a la possibilité de surveiller un premier canal physique sur la base du premier message de configuration. De cette manière, après avoir acquis le second message de configuration, la station de base transmet un premier message d'indication à l'équipement d'utilisateur via le premier canal physique, et l'équipement d'utilisateur a la possibilité de déterminer une procédure sur laquelle l'équipement d'utilisateur doit exécuter une transmission sur la liaison montante, en déterminant si la procédure ou un ensemble de procédures sont en conflit, ou non; autrement, sur la base des données d'état de traitement qui sont contenues dans le premier message de configuration, une activation ou une désactivation sont directement exécutées sur une procédure HARQ. Cela peut permettre à l'équipement d'utilisateur d'éviter que la procédure employée ne soit en conflit avec la procédure employée par un équipement d'utilisateur d'une cellule de même fréquence qui est voisine d'une cellule de desserte, tout en exécutant une transmission de données sur la liaison montante. De cette manière, le brouillage de l'équipement d'utilisateur qui se trouve dans la cellule de même fréquence qui est voisine d'une cellule de desserte peut être réduit. La présente invention est ainsi apte à réduire le brouillage de l'équipement d'utilisateur sur un équipement qui se trouve dans une cellule de même fréquence qui est voisine d'une cellule de desserte, quand l'équipement d'utilisateur se trouve sur le bord de la cellule.
