Abstract

La présente invention concerne un procédé de transmission de données de liaison latérale. Le procédé consiste : à transmettre, à une station de base, des informations d'une première ressource temps-fréquence pour transmettre un premier type de service de données ; à recevoir des informations de configuration transmises par la station de base, les informations de configuration étant utilisées pour indiquer qu'un équipement utilisateur transmet un second type de service de données sur une seconde ressource temps-fréquence, et la première ressource temps-fréquence étant différente de la seconde ressource temps-fréquence ; et à transmettre le premier type de service de données sur la première ressource temps-fréquence, et à transmettre le second type de service de données sur la seconde ressource temps-fréquence. Selon les modes de réalisation de la présente invention, la station de base peut déterminer les emplacements de la première ressource temps-fréquence dans un domaine temporel et un domaine fréquentiel, de sorte que la station de base détermine la seconde ressource temps-fréquence qui est différente de la première ressource temps-fréquence, de telle sorte que l'équipement utilisateur puisse transmettre respectivement le premier type de service de données et le second type de service de données sur différentes ressources temps-fréquence, ce qui assure une transmission régulière des deux types de données de service et garantit ainsi un bon effet de communication de l'équipement utilisateur.
