Abstract

L'invention concerne un procédé et un dispositif d'attribution de ressources de D2D. Le procédé consiste à : apprendre qu'une collision de ressources s'est produite sur une sous-trame de D2D sélectionnée par auto-organisation; et demander à une station de base de commander l'attribution de ressources de D2D. Etant donné que la station de base participe à l'attribution de ressources de D2D, des opérations de sécurité telles qu'une authentification sont mises en œuvre, la nécessité de transmettre des informations sécurisées sur une liaison de D2D est soit inutile soit réduite, ce qui permet, par comparaison avec une solution faisant uniquement appel à l'auto-organisation pour l'attribution de ressources de D2D, de réduire des surcharges de sécurité et d'obtenir un débit de système. En outre, l'utilisation d'une combinaison d'auto-organisation et de commande par une station de base pour l'attribution de ressources de D2D, par comparaison avec une attribution de ressources de D2D par une station de base uniquement, offre une efficacité d'attribution de ressources.
