Abstract

L'invention concerne un procédé et un appareil de commande d'activation de protocole HARQ-ACK, et un dispositif et un support de stockage. Lors du procédé selon la présente invention, un dispositif de réseau transporte une information de commande d'activation de protocole HARQ-ACK dans un domaine d'information spécifique d'information de commande liaison descendante (DCI), et la transmet à un dispositif de terminal; et le dispositif de terminal détermine, selon l'information de commande d'activation de protocole HARQ-ACK, s'il faut renvoyer une information de rétroaction de protocole HARQ-ACK au dispositif de réseau. Par conséquent, la décision quant à savoir si un équipement utilisateur (UE) doit renvoyer une information de rétroaction de protocole HARQ-ACK à un dispositif de réseau peut être contrôlée de manière flexible selon une information de commande d'activation de HARQ-ACK, et une commande d'activation de protocole HARQ-ACK est réalisée, de sorte que la consommation de ressources provoquée par une rétroaction de protocole HARQ-ACK inutile peut être réduite. En outre, l'information de commande d'activation de protocole HARQ-ACK est transportée dans un domaine d'information spécifique dans l'information DCI, et, par conséquent, il n'y a aucune nécessité d'ajouter un domaine d'information supplémentaire dans l'information DCI, de sorte qu'il n'y aucune influence sur la performance de réception d'un canal PDCCH et la complexité de la détection de canal PDCCH.
