Abstract

L'invention porte sur un procédé et un dispositif pour déterminer un secteur dans lequel un équipement utilisateur (UE) est situé. Le procédé pour déterminer un secteur dans lequel un UE est situé peut consister à : acquérir une première valeur de caractérisation de qualité de canal d'un premier secteur correspondant à un UE ; acquérir une seconde valeur de caractérisation de qualité de canal d'un second secteur correspondant à l'UE ; et acquérir une valeur relative de la première valeur de caractérisation de qualité de canal par rapport à la seconde valeur de caractérisation de qualité de canal, et en fonction de la valeur relative, déterminer un secteur dans lequel l'UE est situé. La solution de la présente invention facilite une amélioration de la précision de distinction d'un secteur auquel un UE appartient.
