Abstract

L'invention concerne des procédés et des dispositifs de communication permettant de transmettre des données sur un canal radio. Ces procédés consistent : à déterminer (32) un premier format de préambule à utiliser dans une cellule du deuxième dispositif de communication; à déterminer (34) une valeur de décalage circulaire de base à partir d'un ensemble de valeurs de décalage circulaire de base, cet ensemble étant sélectionné en fonction du format de préambule; et à transmettre (36) des données contenant une indication du premier format de préambule déterminé et un pointeur de valeur de décalage circulaire de base indiquant la valeur de décalage circulaire de base dans l'ensemble de valeurs.
