Abstract

L'invention se rapporte à un procédé qui permet de multiplexer et transmettre les données d'une pluralité d'équipements utilisateurs dans un système de communication mobile, et à un système associé. Le système et le procédé de l'invention réduisent la charge de traitement qui s'exerce sur l'équipement utilisateur et les exigences de retransmission du noeud B lors du multiplexage des données d'une pluralité d'équipements utilisateur dans un TTI d'un HS-PDSCH. Selon l'invention, les équipements utisateur sont groupés et après le multiplexage, les données du groupe sont transmises en aval, l'identification temporaire étant divisée en deux parties, l'une des parties indiquant l'identification du groupe d'équipements utilisateur et l'autre partie indiquant s'il y a une transmission de données pour chaque équipement utilisateur du groupe. Chaque équipement utilisateur du groupe analyse le H-RNTI reçu et ne reçoit les données respectives en provenance du canal partagé que lorsque la transmission de données lui est destinée. Lorsque l'équipement utilisateur du groupe est informé de l'existence d'une transmission de données qui lui est destinée, l'équipement utilisateur détermine si les données sont des données de retransmission et si ces données ont déjà été reçues correctement par l'équipement utilisateur, ce dernier ne les reçoit plus.
