Abstract

La présente divulgation concerne un procédé et un appareil d'accès au réseau, un équipement utilisateur, un dispositif de réseau d'accès et un support de stockage, et appartient au domaine technique des communications. Le procédé comprend l'étape suivante : un dispositif de réseau d'accès envoie des premières informations d'indication et/ou des secondes informations d'indication à un UE, les premières informations d'indication et/ou les secondes informations d'indication étant utilisées pour indiquer un état d'autorisation d'une bande de fréquences cible à l'UE. Ainsi, le mode de réalisation de la présente divulgation concerne un procédé spécifique permettant à un UE d'accéder à une bande de fréquences dans une attribution de spectre incohérente, ce qui résout le problème de l'attribution de spectre incohérente dans différents pays, tout en réduisant également l'impact sur des protocoles existants, et assure une communication normale d'UE entre différents pays.
