Abstract

La présente invention concerne un procédé et un dispositif de transmission d'informations, aptes à résoudre le problème selon lequel, lorsque les ressources de canal de différents types de service se chevauchent, si les règlements Rel-15 sont suivis, les exigences de temps doivent être satisfaites entre les canaux avec des ressources chevauchantes, et le retard de transmission du service URLLC augmentera. Un procédé de transmission d'informations fourni par le mode de réalisation de la présente invention consiste à : déterminer que les ressources de canal de différents types de service se chevauchent ; et transmettre les informations du type de service d'après la priorité du type de service. Selon la présente invention, lorsque les ressources de canal de différents types de service se chevauchent, les informations du type de service d'après la priorité du type de service peuvent être transmises d'après la priorité du type de service, et l'augmentation du retard de transmission du service URLLC peut être évitée.
