Abstract

La présente invention concerne un procédé et un appareil de renvoi de livres de codes d'acquittement de demande de répétition automatique hybride (HARQ-ACK). Lorsque des positions, dans le domaine temporel, de tous les PUCCH dans N ressources de PUCCH se recouvrent toutes sur la position, dans le domaine temporel, d'un CG-PUSCH, un dispositif de terminal code conjointement un ou plusieurs livres de code de HARQ-ACK dans N livres de codes de HARQ-ACK et des CG-UCI, et envoie, au moyen du CG-PUSCH, des informations des CG-UCI et du ou des livres de codes de HARQ-ACK qui ont été codés conjointement de sorte que les CG-UCI et le ou les livres de codes de HARQ-ACK peuvent tous être envoyés normalement, et par conséquent, la fiabilité des transmissions de données est assurée ; ou le dispositif de terminal détermine de ne pas coder conjointement les livres de codes de N HARQ-ACK et les CG-UCI, annule l'envoi du CG-PUSCH et envoie uniquement les N livres de codes de HARQ-ACK. L'envoi de N livres de codes de HARQ-ACK est de préférence assuré de sorte qu'un retard temporel de transmission de données de service de liaison descendante est réduit et la fiabilité d'un service est ainsi assurée.
