Abstract

La présente demande concerne des procédés de communication sans fil et des dispositifs terminaux. Lorsqu'un dispositif terminal se trouve à l'extérieur d'une couverture réseau, le dispositif terminal peut acquérir des ressources de transmission fiables au moyen d'un terminal en vis-à-vis, et le dispositif terminal peut également garantir la fiabilité des ressources sans effectuer une opération de détection, ce qui permet de réduire la consommation d'énergie du dispositif terminal. Un procédé de communication sans fil comprend l'étape suivante : un premier dispositif terminal détermine qu'un service cible correspond à un premier mode d'attribution de ressources, le premier mode d'attribution de ressources étant un mode dans lequel un second dispositif terminal programme le premier dispositif terminal au moyen d'une connexion de diffusion individuelle (S210).
