Abstract

La présente divulgation concerne un procédé de partage de ressources, un terminal, et un dispositif de réseau. Le procédé de partage de ressources, qui est appliqué à un terminal, consiste : à sélectionner une ressource d'accès aléatoire. La ressource d'accès aléatoire est utilisée pour indiquer s'il faut permettre à un dispositif de réseau de partager le temps d'occupation de canal (COT) du terminal.
