Abstract

La présente demande se rapporte au domaine des communications mobiles. Des procédés et des appareils de configuration d'un signal de référence de positionnement de liaison montante, un dispositif, et un support de stockage sont divulgués. Un procédé de configuration d'un signal de référence de positionnement de liaison montante consiste à : envoyer des informations d'état de configuration de signal de référence de positionnement de liaison montante d'un terminal. Un terminal envoie des informations d'état d'une configuration de signal de référence de positionnement de liaison montante, de sorte qu'un dispositif de réseau qui configure un signal de référence de positionnement de liaison montante pour le terminal peut apprendre la condition de configuration de signal de référence de positionnement de liaison montante actuelle du terminal. Ainsi, le dispositif de réseau qui configure un signal de référence de positionnement de liaison montante pour le terminal peut configurer un signal de référence de positionnement de liaison montante pour le terminal de manière ciblée selon l'état de configuration de signal de référence de positionnement de liaison montante du terminal. Le fait que des configurations de signal de référence de positionnement de liaison montante stockées dans un dispositif de réseau et un terminal soient différentes peut être évité, et l'utilisation par le terminal d'une mauvaise configuration de signal de référence de positionnement de liaison montante peut être évitée.
