Le procédé comprend les étapes suivantes : un dispositif terminal reçoit les premières informations d'indication envoyées par un dispositif de réseau, les premières informations d'indication indiquant les premières ressources temps-fréquence pour transmettre un canal cible ; le dispositif de terminal détecte un signal de référence cible dans les premières ressources temps-fréquence ; le dispositif de terminal démodule le canal cible en fonction du résultat de détection du signal de référence cible. De cette manière, le dispositif de terminal peut démoduler de manière flexible le canal reçu.
