Abstract

La présente demande concerne un procédé d'activation de transmission sans autorisation et un appareil. Dans le procédé, lorsque des DCI de planification de retransmission sont utilisées pour activer simultanément une transmission sans autorisation, un terminal peut déterminer, sur la base des DCI de planification de retransmission, un mode d'application d'application d'un premier paramètre, et déterminer que le mode d'application est cohérent avec un mode d'application d'un dispositif réseau appliquant le premier paramètre. La cohérence du dispositif réseau et du terminal appliquant le premier paramètre utilisé évite une défaillance de retransmission de canal partagé de liaison montante physique (PUSCH) et/ou une défaillance de transmission sans autorisation.
