Abstract

La présente invention se rapporte à un procédé et à un équipement permettant de déterminer un schéma de transmission dans un système de transmission multipoint coordonnée (CoMP). Le procédé comprend les étapes suivantes : une station de base de desserte transmet des signaux indicatifs de type rapport à une station mobile, et elle prévoit des schémas de transmission candidats ; sur la base des signaux indicatifs de type rapport, la station mobile calcule et rapporte des informations relatives au canal de transport sur la liaison descendante dans un groupe de mesures de CoMP d'au moins un schéma de transmission candidat parmi des schémas de transmission candidats prévus ; sur la base des informations de canal de transport rapportées par la station mobile, la station de base de desserte détermine le schéma de transmission devant être adopté ; et la station de base de desserte communique le schéma de transmission déterminé à la station mobile. Par le procédé et l'équipement de la présente invention, la commutation prenant en charge une pluralité de schémas de transmission peut être fournie et les informations en retour relatives au programme de sélection de fréquence dans l'existence d'une pluralité de schémas de transmission peuvent être prises en charge.
