Abstract

Les modes de réalisation de la présente invention concernent un procédé et un appareil d'attribution de ressource, et un procédé et un appareil de vérification d'intégrité. Une première station de base ou une unité distribuée attribue à un dispositif terminal une ressource de liaison montante dédiée parmi des ressources de liaison montante gérées par la première station de base ou l'unité distribuée elle-même, et envoie la ressource de liaison montante dédiée au dispositif terminal ; la première station de base ou l'unité distribuée reçoit des informations envoyées par le dispositif terminal à l'aide de la ressource de liaison montante dédiée reçue. Selon le procédé et l'appareil d'attribution de ressource décrits dans l'invention, une ressource est attribuée et envoyée à un dispositif terminal avant que la vérification d'intégrité ne soit exécutée sur le dispositif terminal, ce qui réduit le délai d'attente durant l'attribution d'une ressource.
