Abstract

La présente invention concerne le domaine des communications mobiles, et divulgue un procédé et un appareil de retour d'informations d'accusé de réception de demande automatique de répétition hybride (HARQ-ACK), un dispositif et un support. Le procédé de retour d'informations HARQ-ACK comprend les étapes consistant : à recevoir un premier canal physique, le premier canal physique correspondant à une première unité de temps de retour ; et à déterminer, en fonction de la réception du premier canal physique, s'il faut transmettre des informations HARQ-ACK au moyen de la première unité de temps de retour. Selon le procédé de retour d'informations HARQ-ACK décrit par la présente invention, un terminal peut déterminer, en fonction de la réception du premier canal physique, s'il faut renvoyer les informations HARQ-ACK, permettant ainsi d'assurer la cohérence d'un dispositif réseau et du terminal sur la nécessité de renvoyer les informations HARQ-ACK.
