Abstract

Selon ses modes de réalisation, la présente invention concerne un procédé de configuration de ressources, un appareil de configuration de ressources et un système. Au cours dudit procédé, une station de base envoie à un utilisateur D2D des informations de configuration de ressources qui indiquent l'envoi et la réception de ressources de l'utilisateur D2D pour la découverte et/ou la communication D2D. Grâce à l'envoi direct des informations de configuration de ressources à l'utilisateur D2D, ce dernier peut envoyer et recevoir des données selon les ressources configurées pour l'utilisateur, ce qui améliore l'utilisation des ressources et évite les erreurs système.
