Abstract

La présente invention concerne un procédé et un dispositif de communication se rapportant au domaine technique des communications. Dans le procédé, un second dispositif détermine un paramètre de configuration d'un signal de demande de répétition automatique hybride (HARQ) sur la base d'une valeur de décalage de fréquence du second dispositif, et transmet le signal HARQ sur la base du paramètre de configuration du signal HARQ. De cette manière, l'effet indésirable de la valeur de décalage de fréquence du second dispositif sur le processus de communication entre le second dispositif et un premier dispositif peut être réduit. Par exemple, le premier dispositif peut démoduler correctement le signal HARQ, etc.
