Abstract

Des modes de réalisation de la présente divulgation concernent un procédé d'envoi de demande d'informations de coordination interne entre des dispositifs terminaux de liaison latérale, et un appareil associé, applicables à des systèmes tels que l'internet des véhicules, V2X et V2V. Le procédé est mis en œuvre par un premier dispositif terminal, et consiste à : selon une durée définie d'un temporisateur et une valeur de comptage d'un compteur, déterminer s'il faut arrêter l'envoi ou la génération d'une demande d'informations de coordination entre des dispositifs terminaux. Par la mise en œuvre des modes de réalisation de la présente divulgation, le premier dispositif terminal peut être empêché d'envoyer ou de générer en continu une demande d'informations de coordination entre des dispositifs terminaux sans connaître le mode d'attribution de ressources et/ou la capacité d'un second dispositif terminal, ce qui permet d'éviter un gaspillage de signalisation et de réduire les interférences vers d'autres dispositifs terminaux.
