Abstract

Cette invention concerne un procédé utilisé pour un accès aléatoire, un dispositif de réseau et un dispositif de terminal, le procédé comprenant les étapes consistant à : générer, par un dispositif de réseau, un premier identifiant provisoire de réseau radio à accès aléatoire (RA-RNTI), en fonction d'informations de ressource détectées d'un canal physique partagé en liaison montante (PUSCH) ; et utiliser, par le dispositif de réseau, le premier identifiant RA-RNTI pour brouiller un contrôle de redondance cyclique (CDC) d'un premier canal physique de contrôle de liaison descendante (PDCCH), le premier PDCCH étant utilisé pour planifier un message de réponse d'accès aléatoire pendant un premier processus d'accès aléatoire.
