Abstract

L'invention concerne un procédé et un appareil de localisation, un équipement utilisateur, une station de base, un dispositif de réseau central et un support de stockage, qui appartiennent au domaine technique des communications. Le procédé comprend : un dispositif de réseau central envoyant des informations d'indication à une station de base, les informations d'indication étant utilisées pour ordonner à la station de base de déterminer des informations de configuration d'un signal de référence de localisation de liaison montante pour un UE qui est appliqué dans un état non connecté de commande de ressources radio (RRC). Le procédé de localisation peut être appliqué à la localisation d'un UE dans un état RRC non connecté, avec une large gamme d'applications.
