Abstract

L'invention porte sur un procédé d'accès aléatoire, sur un nœud B évolué et sur un équipement terminal. Le procédé comprend les étapes suivantes consistant à : déterminer une ou plusieurs porteuses de composition devant être détectées par l'équipement utilisateur (UE) dans l'état de réception discontinue (DRX), informer l'équipement utilisateur de la ou des porteuses de composition, et transmettre le message de réponse d'accès aléatoire sur l'une des porteuses de composition déterminées après réception du préambule d'accès aléatoire dédié envoyé par l'UE. Par conséquent, le nœud B évolué pourrait déterminer la porteuse de liaison descendante détectée par l'UE lorsque l'UE est dans le processus d'accès aléatoire non compétitif de l'état DRX, le taux d'utilisation de la ressource de liaison descendante est augmenté et la consommation d'électricité de l'UE est réduite.
