Le procédé consiste à : déterminer des premières informations de configuration; les premières informations de configuration étant utilisées pour configurer une première avance temporelle (TA) correspondant à un premier index de groupes d'ensembles de ressources de commande CoresetPoolIndex et/ou une seconde TA correspondant à un second CoresetPoolIndex, le premier CoresetPoolIndex et le second CoresetPoolIndex étant chacun associé à une première cellule; et envoyer les premières informations de configuration. De cette manière, une configuration de TA peut être mise en œuvre pour un ou plusieurs CoresetPoolIndex associés à la première cellule, ce qui facilite la synchronisation temporelle du côté dispositif de réseau.
