Abstract

La présente invention se rapporte à un procédé et à un dispositif adaptés pour traiter des interférences de coexistence à l'intérieur d'un même module. Le procédé selon l'invention consiste : à déterminer si un état d'interférence d'un premier module de communication radio dans un équipement d'utilisateur (UE, User Equipment) sur une fréquence de fonctionnement change ou non et/ou à déterminer si un état d'interférence du premier module de communication radio dans l'UE sur des fréquences autres que la fréquence de fonctionnement change ou non; et, si le résultat de la détermination est positif, à rapporter à un côté réseau un niveau d'interférence sur la fréquence de fonctionnement et/ou les autres fréquences. La présente invention permet de garantir que le côté réseau maîtrise des interférences de coexistence à l'intérieur d'un même module pour l'UE sur la durée. Ceci permet de régler la fréquence de fonctionnement de l'UE sur la durée, en fonction de la sévérité des interférences de coexistence à l'intérieur d'un même module via le côté réseau.
