Abstract

La présente invention concerne un procédé de détermination d'une numérologie de base, un terminal et un dispositif de réseau. Le procédé comprend les étapes suivantes : un terminal désembrouille un code de contrôle de redondance cyclique (CRC) dans des informations de commande de liaison descendante au moyen d'au moins un premier identifiant temporaire de réseau radio (RNTI), et détermine un premier RNTI qui désembrouille avec succès le CRC parmi le ou les premiers RNTI, en tant que RNTI cible ; et, en fonction du RNTI cible et d'une correspondance entre le ou les premiers RNTI et numérologies de base, le terminal détermine une numérologie de base cible utilisée pour transmettre des données. Dans des modes de réalisation de la présente invention, un CRC dans des informations de commande de liaison descendante est brouillé à l'aide d'un premier RNTI, une numérologie de base est indiquée au moyen du premier RNTI, et, par conséquent, la nécessité d'ajouter un domaine d'indication utilisé pour indiquer le type de la numérologie de base dans les informations de commande de liaison descendante selon l'état de la technique est évitée, de sorte à réduire les surcharges de signalisation provoquées par la numérologie de base pour indiquer des données transmises.
