Abstract

La présente invention concerne un procédé d'ordonnancement des ressources qui peut prendre en charge la baisse des surcharges sur les ressources de transmission pour permettre un ordonnancement des ressources. Le procédé est appliqué à un réseau local sans fil et la position d'un bloc de ressources qui peut être divisé par rapport à une ressource de domaine de fréquence qui doit être allouée est fixée dans un protocole de prochaine génération suivi par le réseau local sans fil. Le procédé comprend les étapes suivantes : une extrémité d'envoi génère des informations d'ordonnancement des ressources, les informations d'ordonnancement des ressources comprenant une séquence de bit destinée à indiquer un bloc de ressources à allouer qui est en réalité divisé à partir d'une ressource de domaine de fréquence à allouer, et au moins quelques bits de la séquence de bit étant utilisés pour indiquer si un segment de ressource de domaine de fréquence ayant une largeur de domaine de fréquence spécifiée dans la ressource de domaine de fréquence à allouer est alloué à un nombre prédéfini d'extrémités de réception (S110) ; et envoie les informations d'ordonnancement des ressources aux extrémités de réception (S120).
