Abstract

Les modes de réalisation de l'invention concernent un procédé et un dispositif d'attribution de ressources inverses, ainsi qu'un support de stockage informatique, le procédé consistant : à déterminer dans une plage de rapport signal sur bruit de communication inverse un intervalle de rapport signal sur bruit auquel appartient le rapport signal sur bruit d'un canal cible ; la plage de rapport signal sur bruit de communication inverse comprenant au moins deux intervalles de rapport signal sur bruit, chaque intervalle de rapport signal sur bruit desdits deux intervalles au moins correspondant à un rapport signal sur bruit différent ; et à attribuer au canal cible des ressources inverses correspondantes en fonction des intervalles de rapport signal sur bruit différents auxquels appartient le rapport signal sur bruit du canal cible.
