Abstract

La présente invention concerne un procédé de suppression d'interférences entre cellules adjacentes faisant appel : à la réception d'une signalisation d'interférences envoyée par une quelconque station de base et à l'obtention d'informations d'un équipement d'utilisateur (UE) dans une zone d'interférences de la station de base, la zone d'interférences étant une zone dans laquelle l'UE qui se trouve dans la zone interfère avec la station de base lors d'un envoi de données mais dans laquelle la station de base ne peut pas commander l'UE qui se trouve dans la zone; à l'obtention d'informations d'une partie des stations de base ou de toutes les stations de base qui commandent l'UE; et à l'envoi des premières informations d'instruction de diminution de puissance d'émission à la partie des stations de base ou à toutes les stations de base de façon à amener la partie des stations de base ou toutes les stations de base à réduire la puissance d'émission de l'UE. Le procédé de suppression des interférences entre cellules adjacentes des modes de réalisation de la présente invention peut faire appel à un appareil de commande de réseau et à d'autres stations de base pour réduire la puissance d'émission de l'UE, en supprimant ainsi les interférences d'une cellule adjacente.
