Abstract

La présente invention concerne une technique pour un système de communication secondaire pour utiliser un spectre conçu pour un autre système de communication (ou système de communication primaire). En rangeant une pluralité de stations de base secondaires sur la base d’une puissance de transmission de station de base, d’une puissance de transmission nécessaire calculée et d’un affaiblissement de propagation, un jeu de critères est développé pour sélectionner une station de base secondaire de rang le plus élevé pour le fonctionnement au sein d’un spectre du système primaire. Le classement en rangs peut être adapté sur la base de la mobilité de l’abonné du système secondaire, et en tant que tel, le système secondaire communique au sein du spectre du système primaire en utilisant les stations de base qui ont subi un classement adaptatif. La sélection de canal peut également être classée en rangs. La technique et l’appareil permettent à un réseau radio cognitif (CR) de fonctionner au sein d’un spectre du réseau titulaire.
