Abstract

L'invention concerne un procédé permettant à un premier terminal de communiquer dans un système de communication sans fil, et un dispositif le prenant en charge. Le procédé peut comprendre: une étape de réception, en provenance d'une station de base, d'informations concernant un premier groupement de ressources et d'informations concernant un second groupement de ressources; une étape de détermination d'un groupement de ressources pour une liaison latérale parmi le premier groupement de ressources et le second groupement de ressources sur la base d'un état de gestion des ressources radioélectriques (RRC) du premier terminal et suivant que le premier terminal est compris ou non dans la couverture de la station de base; et une étape de transmission, à un second terminal, d'informations concernant le groupement de ressources pour la liaison latérale.
