Abstract

La présente invention concerne un procédé et un dispositif de transmission à base de liaison latérale. Le procédé consiste à : télécharger en amont les listes d'une pluralité de listes d'adresses alternatives dans une station de base ; déterminer un identifiant de type d'adresse cible et un premier numéro d'index cible conformément à l'adresse de destination courante correspondant aux données courantes à transmettre ; et rapporter l'identifiant de type d'adresse cible et le premier numéro d'index à la station de base, de sorte que la station de base détermine, après la détermination de la première adresse cible dans les listes de la pluralité de listes d'adresses alternatives conformément à l'identifiant de type d'adresse, l'adresse de destination courante conformément au premier numéro d'index cible dans la liste d'adresses cibles. Selon la présente invention, lors d'un processus de transmission à base de liaison latérale, les modes de transmission correspondant à différents identifiants de type d'adresse sont différentiés, de sorte que la station de base puisse ultérieurement employer des politiques de programmation de ressources correspondantes sur la base des différents modes de transmission, de façon à permettre au processus de programmation de ressources et de mesure de configuration de mieux satisfaire à des exigences de service.
