Abstract

L'invention concerne un procédé, un appareil et un dispositif de planification, ces derniers étant utilisés pour résoudre le problème, dans l'état de la technique, d'un retard de service accru durant la transmission d'un service entre un véhicule et tout (V2X) à l'aide d'une ressource SPS en raison du fait qu'un temps d'arrivée de service V2X ne correspond pas à une ressource SPS. Le procédé consiste : à déterminer une fenêtre SPS correspondant à une direction de transmission selon une occasion SPS et une longueur de fenêtre SPS configurée dans la direction de transmission, la fenêtre SPS prenant l'occasion SPS comme moment final ; lorsqu'il est déterminé que le temps d'arrivée de données dans la direction de transmission est situé dans la fenêtre SPS correspondant à la direction de transmission, à transmettre les données d'une manière SPS ; et lorsqu'il est déterminé que le temps d'arrivée de données dans la direction de transmission est situé en dehors de la fenêtre SPS correspondant à la direction de transmission, transmettre les données d'une manière de planification dynamique. De cette manière, le surdébit de signalisation peut être réduit autant que possible tout en garantissant le fait que l'exigence de retard de service est satisfaite.
