Abstract

La présente invention concerne un procédé de communication et un dispositif associé qui sont utilisés pour la transmission de données dans l'Internet des véhicules. Le procédé comprend les étapes suivantes : un dispositif de terminal envoie un premier message à un dispositif de réseau d'accès radio, le premier message pouvant comprendre un premier ensemble et des premières informations d'indication, le premier ensemble étant un ensemble de ressources de fréquence d'une première liaison latérale de format prise en charge par le dispositif de terminal, les premières informations d'indication comprenant des informations indiquant si le premier ensemble et au moins un ensemble peuvent prendre en charge une transmission de données en même temps et le au moins un ensemble étant un ensemble de ressources de fréquence d'une seconde liaison latérale de format prise en charge par le premier dispositif de terminal. Le dispositif de terminal reçoit un second message provenant du dispositif de réseau d'accès radio, le second message pouvant comprendre : des informations de ressource de fréquence de la première liaison latérale de format et/ou des informations de ressource de fréquence de la seconde liaison latérale de format qui sont configurées par le dispositif de réseau d'accès radio pour le dispositif de terminal. En mettant en œuvre le présent procédé, des conflits de transmission peuvent être évités lorsque le dispositif de réseau d'accès radio configure les ressources de fréquence de la liaison latérale pour le dispositif de terminal.
