Abstract

Les modes de réalisation de la présente invention concernent un procédé de configuration de ressources de transmission, un dispositif d'accès et un terminal ; le dispositif d'accès configure un premier ensemble CBB pour le terminal, un premier CBB dans le premier ensemble CBB étant divisé en un ou plusieurs sous-CBB ; le dispositif d'accès envoie au terminal des premières informations d'indication contenant des informations du CBB dans le premier ensemble CBB et des informations du sous-CBB, de telle sorte que le terminal sélectionne une sous-CBB cible à partir du premier ensemble CBB sur la base des premières informations d'indication, et transmet des informations de liaison montante ; lorsque le taux de pénétration du terminal est faible, les ressources basées sur la contention sont ainsi économisées.
