Abstract

La présente invention concerne un appareil et un procédé de communication (D2D) de dispositif à dispositif. Le procédé comprend les étapes suivantes : un terminal de réseautage de véhicule, conformément à des informations de configuration de ressource reçues, établit une période d'envoi d'une ressource D2D du terminal de réseautage de véhicule et un créneau temporel pour envoyer un message périodique D2D; et en fonction de chaque période d'envoi, lors de la détection du fait que le créneau temporel destiné à envoyer le message périodique D2D dans la période est atteint, le terminal de réseautage de véhicule envoie le message périodique D2D courant à un récepteur.
