Abstract
L'invention concerne un procédé de retour, un dispositif terminal et un dispositif réseau. Le procédé de retour comprend les étapes suivantes : un dispositif terminal reçoit une première signalisation, la première signalisation étant utilisée pour ordonner au dispositif terminal de renvoyer des informations de retour correspondant à un premier groupe de processus HARQ ; le dispositif terminal reçoit une seconde signalisation, la seconde signalisation étant utilisée pour ordonner au dispositif terminal de renvoyer des informations de retour correspondant à un second groupe de processus HARQ, et les processus HARQ compris dans le premier groupe de processus HARQ étant partiellement différents ou complètement différents des processus HARQ compris dans le second groupe de processus HARQ ; et le dispositif terminal génère un livre de codes de retour, le livre de codes de retour comprenant des informations de retour d'un troisième groupe de processus HARQ, et le troisième groupe de processus HARQ comprenant le premier groupe de processus HARQ et le second groupe de processus HARQ. Dans des modes de réalisation de la présente demande, une pluralité de combinaisons de signalisation sont utilisées pour indiquer quelles procédures HARQ du dispositif terminal doivent être renvoyées par le livre de codes de retour, de sorte à fournir un mode de génération relativement flexible du livre de codes de retour sur la base d'une commande de manière raisonnable du surdébit de signalisation.
