Abstract

La présente invention concerne un procédé d'ordonnancement de ressources d'un canal physique partagé en liaison ascendante (PUSCH). Le procédé comprend les étapes au cours desquelles : une station de base à laquelle appartient une cellule obtient les informations sur les ressources d'un canal physique d'accès aléatoire (PRACH) relatives à un élément voisin de la cellule ; un ordonnancement de ressources du PUSCH pour un terminal d'utilisateur dans la cellule est exécuté en fonction des informations obtenues sur les ressources du PRACH relatives à l'élément voisin de la cellule. La présente invention concerne également un système correspondant d'ordonnancement de ressources d'un PUSCH. La présente invention permet à la station de base de commander l'attribution de ressources d'un PUSCH d'une cellule de façon à éviter les ressources utilisées par le PRACH de l'élément voisin de la cellule. L'ordonnancement de ressources d'un PUSCH de la cellule provoquera donc moins d'interférence sur le PRACH de l'élément voisin de la cellule, ce qui accroît la précision de l'analyse du signal du PRACH de l'élément voisin et, de plus, augmente la probabilité d'accès tout en diminuant le délai d'accès.
