Abstract

L'invention porte sur un procédé et un appareil pour supporter l'agrégation de multiples porteuses composantes. Une unité d'émission/réception sans fil (WTRU) dans un état de veille effectue une recherche de cellule pour détecter une porteuse d'ancrage de liaison descendante et campe sur la porteuse d'ancrage de liaison descendante. La porteuse d'ancrage de liaison descendante est une porteuse composante et peut être attribuée pour une synchronisation et des opérations en mode de veille pour la WTRU. La WTRU par l'intermédiaire de la porteuse d'ancrage de liaison descendante reçoit un canal de diffusion pour un message de diffusion, un canal d'appel pour un message d'appel, et un canal de commande pour des informations de commande nécessaires dans l'état de veille. La WTRU reçoit des données par l'intermédiaire d'une porteuse agrégée comprenant au moins deux porteuses composantes comprenant une porteuse de données. La porteuse de données est une porteuse composante attribuée pour un transfert de données à la WTRU dans un état connecté.
