Abstract

La présente invention concerne un procédé et équipement destinés à configurer un mode de transmission de signaux d'un système de communications sans fil. Au moins deux modes de transmission sont configurés pour un UE au moyen d'une signalisation de configuration semi-statique, des ensembles de TTI différents correspondant à des modes de transmission différents, de telle façon qu'un équipement de réseau puisse envoyer à l'UE la signalisation d'un format de DCI correspondant à un mode de transmission correspondant à l'ensemble de TTI auquel appartient le TTI avec différents TTI, de façon à déléguer à l'UE l'emploi du mode de transmission correspondant à la signalisation pour transférer des signaux, réduisant ainsi efficacement la surcharge de signalisation causée par la configuration du mode de transmission, réduisant la charge du canal et améliorant le rendement de la configuration.
