Abstract

La présente demande concerne un procédé et un appareil de configuration, ainsi qu'un support de stockage lisible. Le procédé de configuration comprend les étapes suivantes : un dispositif de réseau envoie un message de reconfiguration à un dispositif terminal, le message de reconfiguration étant utilisé pour mettre à jour des informations de configuration, le message de reconfiguration étant planifié sur la base de premières informations de commande de liaison descendante (DCI), les premières DCI étant transportées sur un premier canal de commande de liaison descendante physique (PDCCH), le premier PDCCH étant associé à des premières informations de configuration, et les premières informations de configuration étant des informations de configuration avant que les informations de configuration ne soient mises à jour ; et le dispositif de réseau reçoit un message d'achèvement de reconfiguration, qui provient du dispositif terminal et répond au message de reconfiguration. Sur la base de la solution technique, un dispositif de réseau planifie un message de reconfiguration en utilisant des informations de configuration avant que les informations de configuration ne soient mises à jour, de manière à pouvoir réduire la consommation de PDCCH communs tout en améliorant la fiabilité de réception du message de reconfiguration par un dispositif terminal.
