Abstract

L'invention concerne un procédé de traitement d'interférences, un appareil de traitement d'interférences, et un support de stockage informatique. Lorsque des interférences se produisent dans un réseau sans fil, une planification coordonnée de liaisons utilisées pour transmettre des données dans le réseau sans fil est exécutée, ce qui supprime les interférences entre liaisons et améliore le taux d'utilisation de ressources sans fil. Le procédé décrit dans les modes de réalisation de la présente invention consiste à : recevoir, au moyen d'une sous-trame de mesure, un signal de référence envoyé par un nœud dans un groupe de liaisons, le groupe de liaisons étant un groupe de liaisons utilisées pour transmettre simultanément des données de fréquence identique, les liaisons étant des canaux lorsque la transmission de données est exécutée entre deux nœuds dans le groupe de liaisons, et le signal de référence étant un signal prédéfini du nœud stocké dans le groupe de liaisons ; détecter la condition d'interférence des liaisons du groupe de liaisons d'après le signal de référence, la condition d'interférence comprenant une liaison, du groupe de liaisons, où des interférences se produisent, l'intensité d'interférence, et une source d'interférence ; et exécuter une planification coordonnée sur les liaisons du groupe de liaisons d'après la condition d'interférence.
