Le procédé comprend les étapes suivantes : un dispositif de réseau envoie des premières DCI, les premières DCI étant utilisées pour planifier une transmission de données de liaison descendante qui est portée sur un PDSCH d'une première priorité et/ou pour planifier une transmission de données de liaison descendante qui est portée sur un PDSCH d'une seconde priorité, et de manière correspondante, un dispositif terminal détecte les premières DCI dans un PDCCH ; le dispositif de réseau envoie des secondes DCI, les secondes DCI étant utilisées pour planifier un PUSCH de la seconde priorité, et les secondes DCI comprenant un DAI_UL, et de manière correspondante, le dispositif terminal recevant les secondes DCI ; et le dispositif terminal envoie des premières informations HARQ et/ou des secondes informations HARQ sur le PUSCH selon une situation de détection des premières DCI, et le DAI_UL, et de manière correspondante, le dispositif de réseau reçoit les premières informations HARQ et/ou les secondes informations HARQ.
