Abstract

La présente invention concerne un procédé, un dispositif terminal et un dispositif réseau de transmission de données. Le procédé comprend les étapes suivantes : un terminal détermine une première numérologie selon une première identification (ID) de processus de demande de répétition automatique hybride (HARQ) et des relations de mappage entre des ID de processus HARQ et des numérologies ; le terminal utilise un paramètre de transmission dans la première numérologie pour effectuer une transmission de données à l'aide d'un dispositif réseau. Une numérologie peut être déterminée au moyen d'un identifiant de processus HARQ sur la base de relations de mappage entre des ID de processus HARQ et des numérologies, ce qui permet de résoudre un problème dans l'état de la technique selon lequel un domaine associé à une numérologie doit être ajouté à des DCI pour indiquer la numérologie, et de réduire en conséquence les surdébits de signalisation requis pour indiquer une numérologie utilisée pour la transmission de données.
