Abstract

La présente invention concerne un procédé et un appareil de configuration de ressources, un dispositif informatique et un support d'informations. Un UE reçoit une commande de transfert intercellulaire, effectue un transfert intercellulaire non RACH, et envoie des données de liaison montante à une station de base cible selon une configuration de ressources ordonnée par la commande de transfert intercellulaire ; étant donné que la commande de transfert intercellulaire est utilisée pour ordonner à l'UE d'envoyer la configuration de ressources des données de liaison montante à la station de base cible, et la configuration de ressources est utilisée pour indiquer des ressources à base de configuration de faisceau de l'UE, c'est-à-dire que la station de base cible configure, sur la base d'un faisceau, des ressources de liaison montante utilisées pour envoyer les données de liaison montante ; lorsque l'UE se déplace, le faisceau et les ressources de liaison montante correspondantes sur le faisceau peuvent être sélectionnés dans la configuration de ressources de façon à envoyer les données de liaison montante, ce qui évite le problème du transfert intercellulaire de faisceau provoqué par le mouvement de l'UE qui conduit alors à l'échec d'envoi de données de liaison montante, ce qui permet d'assurer la fiabilité de la transmission de données de liaison montante.
