Abstract

La présente demande se rapporte au domaine des communications mobiles. La présente invention divulgue un procédé et un appareil de planification de ressources, ainsi qu'un dispositif et un support de stockage. Le procédé comprend les étapes suivantes : envoyer des premières informations de planification de ressources à un premier terminal, les premières informations de planification de ressources indiquant un premier ensemble de ressources, le premier ensemble de ressources comprenant au moins une ressource de transmission de liaison latérale qui est utilisée par le second terminal pour effectuer une transmission de liaison latérale, et un premier terminal envoyant les premières informations de planification de ressources au second terminal, de façon à programmer, pour le second terminal, la ressource de transmission de liaison latérale pour une transmission de liaison latérale ; et le second terminal effectuant une transmission de liaison latérale sur la base de la ressource de transmission de liaison latérale, qui est programmée par le premier terminal. De cette manière, il n'est pas nécessaire que le second terminal effectue une détection de ressources, ce qui permet d'éviter un conflit avec des ressources qui sont utilisées par d'autres terminaux et d'améliorer les performances de transmission de liaison latérale du second terminal. En outre, il n'est pas nécessaire que le second terminal effectue une détection de ressources, réduisant ainsi la consommation d'énergie du second terminal.
