Abstract

La présente invention concerne, dans certains modes de réalisation, un procédé, un appareil et un dispositif de programmation de ressources. Le procédé comprend les étapes suivantes : un dispositif terminal transmet des informations de distribution d'un paquet de données à un dispositif réseau; et le dispositif terminal reçoit des informations de configuration en provenance du dispositif réseau, les informations de configuration indiquant une ressource attribuée au dispositif terminal selon les informations de distribution. L'invention résout le problème d'utilisation inefficace de ressources due à l'attribution d'un trop grand nombre de ressources à un dispositif terminal, et atténue le problème de latence de transmission importante résultant de l'attribution d'un trop petit nombre de ressources au dispositif terminal.
