Abstract

L'invention concerne un procédé, un dispositif et un support lisible par ordinateur destinés à l'attribution de ressources de liaison latérale. Un nouveau schéma d'attribution de ressources à des transmissions en liaison latérale est décrit. Chaque dispositif terminal (110-2,110-1,120) se voit affecter une opportunité d'accès au canal spécifique au dispositif terminal (110-2,110-1,120). La quantité de ressources attribuées aux dispositifs terminaux (110-2,110-1,120) est adaptée en fonction de la quantité de trafic de liaisons latérales entre les dispositifs terminaux (110-2,110-1,120). De cette façon, les collisions sont évitées et l'adaptation à la variation du trafic est réalisée.
