Abstract

L'invention concerne des techniques pour supporter une communication dans un scénario d'interférences dominantes. Un équipement d'utilisateur (UE) peut communiquer avec une première station de base et peut observer de fortes interférences et/ou peut provoquer de fortes interférences vers une seconde station de base. Dans une conception, la première station de base peut utiliser une première bande de fréquences, qui peut chevaucher au moins partiellement une seconde bande de fréquences pour la seconde station de base et peut en outre s'étendre au-delà de la seconde bande de fréquences. La première station de base peut envoyer au moins un signal de synchronisation et un canal de diffusion dans une partie centrale de la première bande de fréquences destinés à être utilisés par des UE pour détecter la première station de base. La seconde bande de fréquences peut ne pas être chevauchée par la partie centrale de la première bande de fréquences. La première station de base peut également communiquer avec au moins un UE sur la première bande de fréquences.
