Abstract

L'invention concerne un appareil et un procédé de transmission d'information programmée, permettant à la station de base de programmer un paquet de liaison montante E0DCH selon le rapport d'information programmée (SI) mise à jour. Selon l'invention, on détermine si les données reçues proviennent de la première transmission moyennant le nombre de séquences de retransmission (RSN) transmis par le E-DPCCH, le cas échéant, on enregistre le moment d'arrivée pour la première transmission des données par mémorisation du nombre de trames de connexion et du nombre de sous-trames correspondant à l'intervalle temporel de transmission (TTI) des données. Après réception des données contenant la SI, on détermine si le moment d'arrivée pour la première transmission de données succède le moment de réception de la dernière SI mémorisée, le cas échéant, on effectue une programmation selon la SI contenue dans les données avant de mettre à jour le moment de réception de la dernière SI mémorisée qui devient alors le moment d'arrivée de la première transmission de données; dans le cas contraire, la SI contenue dans les données est ignorée.
