Abstract

La présente invention concerne un procédé et un dispositif de communication, le procédé comprenant les étapes suivantes : un premier dispositif de communication reçoit des informations de commande, les informations de commande indiquant le nombre L de blocs de ressources attribués au premier dispositif de communication et le nombre N de répétitions ; et le premier dispositif de communication envoie un canal de données à un second dispositif de communication en fonction du nombre L de blocs de ressources et du nombre N de répétitions, le nombre L de blocs de ressources se rapportant à un premier ensemble de nombres de blocs de ressources parmi de multiples ensembles de nombres de blocs de ressources, chaque ensemble de nombres de blocs de ressources parmi les multiples ensembles de nombres de blocs de ressources étant associé à un certain nombre d'ensembles de répétitions, le nombre N de répétitions se rapportant à un premier nombre d'ensembles de répétitions et le premier nombre d'ensembles de répétitions étant le nombre d'ensembles de répétitions qui est associé au premier ensemble de nombres de blocs de ressources. La présente invention est avantageuse pour améliorer la rationalité du procédé de combinaison entre le nombre de blocs de ressources et le nombre de répétitions.
