Abstract

La présente invention concerne un procédé, une station de base, un serveur de localisation et un système pour configurer un signal de référence de liaison montante. Le procédé comprend les étapes suivantes: une station de base reçoit des informations de configuration transmises par un serveur de localisation (101); la station de base se rapporte aux informations de configuration pour déterminer un paramètre de configuration pour l'émission d'un signal de référence de liaison montante d'un équipement utilisateur (UE); la station de base configure un paramètre d'émission pour le signal de référence de liaison montante de l'UE sur la base du paramètre de configuration (103); et l'UE émet le signal de référence de liaison montante à la station de base sur la base d'un mode d'émission configuré par la station de base. La présente invention est principalement applicable dans un processus de localisation d'UE et permet de résoudre le problème de réduction de la précision de localisation dû à une mauvaise qualité de signal de référence de liaison montante.
