Abstract

La présente invention concerne un procédé de transmission d'informations, un dispositif de réseau et un dispositif terminal. Le procédé comprend les étapes suivantes : un dispositif de réseau détermine si une préemption de ressource existe ; lorsqu'il est déterminé que la préemption de ressource existe, le dispositif de réseau envoie un premier canal de commande dans une première région de ressource, le premier canal de commande comprenant des premières informations d'indication, les premières informations d'indication étant utilisées pour indiquer une deuxième région de ressource, et la deuxième région de ressource étant une ressource sur laquelle se produit une préemption de ressource ; lorsqu'il est déterminé que la priorité de ressource n'existe pas, le dispositif de réseau envoie un second canal de commande dans une troisième région de ressource, le second canal de commande comprenant des secondes informations d'indication, les secondes informations d'indication n'étant pas utilisées pour indiquer la deuxième région de ressource, et la troisième région de ressource étant différente de la première région de ressource. Au moyen du procédé de transmission d'informations, du dispositif de réseau et du dispositif terminal, le dispositif terminal peut différencier différentes signalisation selon différentes régions de ressource, ce qui contribue à réduire les surdébits de détection aveugles du dispositif terminal.
