Abstract
L'invention concerne un système et des procédés de coordination entre cellules. Le système comprend un macro-terminal et une macro-station de base attribuant à l'avance une ressource radio pour un signal sonore et déterminant une configuration de signal sonore. La macro-station de base délivre à une femto-station de base incluse dans le système des informations sur la configuration du signal sonore. La femto-station de base peut recevoir le signal sonore du macro-terminal sur la base de ces informations et, de cette manière, la femto-station de base peut déterminer si le macro-terminal existe et peut établir un canal entre le macro-terminal et la femto-station de base.
