Abstract

L'invention concerne un procédé et un dispositif de détermination de ressources de transmission. Dans le procédé, un dispositif ou terminal réseau obtient une séquence de RV correspondant à une pluralité d'opportunités de transmission pour la transmission répétée de données, et selon la séquence de RV et n, une RV correspondant à la n-ième opportunité de transmission parmi des opportunités de transmission dont le nombre de symboles répond à une condition prédéfinie parmi K opportunités de transmission est déterminée. Dans le procédé décrit, selon la longueur d'une ressource de domaine temporel et la séquence de RV, la ressource de domaine temporel utilisée par les données est associée à la RV utilisée par les données, et le dispositif ou terminal réseau peut sélectionner pour associer une RV contenant davantage de bits d'informations à une ressource de domaine temporel relativement longue, ce qui permet d'améliorer les capacités de décodage d'une extrémité de réception.
