Abstract

La présente invention concerne un procédé de détermination de ressources et un dispositif de communication. Le procédé de détermination de ressources comprend les étapes suivantes: un premier dispositif terminal détermine un ensemble de ressources de fenêtre de sélection, et lorsque la proportion de ressources après l'ensemble de ressources de fenêtre de sélection exclut un premier ensemble de ressources et un ensemble de ressources non recommandé est inférieure à X% de l'ensemble de ressources de fenêtre de sélection, un premier ensemble de ressources de liaison latérale candidates est une ressource restant après l'exclusion de certaines ressources dans l'ensemble de ressources non recommandé depuis l'ensemble de ressources de fenêtre de sélection, ou d'une ressource restant après l'exclusion supplémentaire du premier ensemble de ressources. La ressource du premier ensemble de ressources comprend des ressources de réservation périodiques dans l'ensemble de ressources de fenêtre de sélection correspondant à des intervalles de temps non surveillés dans une fenêtre d'interception. La proportion de la ressource du premier ensemble de ressources de liaison latérale candidates dans l'ensemble de ressources de fenêtre de sélection est supérieure ou égale à X%, X étant un paramètre de proportion configuré. Au moyen du procédé, il est garanti que le dispositif terminal effectue une sélection de ressources de liaison latérale dans des ressources candidates suffisantes, permettant ainsi d'améliorer la fiabilité de communication.
