According to one embodiment of the invention, a system and a method for maintaining a first history of strength of a first transmission path between a first wireless node and a second wireless node in a multiple input multiple output (MIMO) communication system, maintaining a second history of strength of a second transmission path between a third wireless node and the second wireless node in the MIMO communication system, performing a spatiotemporal correlation between the first history and the second history to determine if any changes in the strength of the first transmission path is observed, and predicting future changes to strength of the second transmission path between the third wireless node and the second wireless node based on the performed special correlation between the first history and the second history.

Dans un de ses modes de réalisation, la présente invention concerne un système et un procédé destinés à la maintenance d'un premier historique de force d'un premier trajet de transmission entre un premier nAEud sans fil et un deuxième nAEud sans fil dans un système de communication MIMO (multiples entrées multiples sorties), la maintenance d'un second historique de force d'un second trajet de transmission entre un troisième nAEud sans fil et le deuxième nAEud sans fil dans le système de communication MIMO, la réalisation d'une corrélation spatiotemporelle entre le premier historique et le second historique afin de déterminer si l'on observe des modifications dans la force du premier trajet de transmission, et la prédiction de modifications à venir de la force du deuxième trajet de transmission entre le troisième nAEud sans fil et le deuxième nAEud sans fil en fonction de la corrélation spéciale réalisée entre le premier historique et le second historique.
