Abstract

Método para proporcionar información de calidad de canal en una red de telecomunicaciones inalámbricas, donde la red comprende una estación de base radial en comunicación inalámbrica con múltiples equipos de usuario por medio de los respectivos canales de transmisión de usuario, y donde la estación de base radial: detecta un ancho de banda de coherencia asociado a un canal de transmisión completo, comprendiendo el canal de transmisión completo los canales de transmisión de usuario de los múltiples equipos de usuario; selecciona una técnica de información para proporcionar información de calidad de canal entre múltiples técnicas de información disponibles, basándose la selección en el ancho de banda de coherencia; transmite un primer mensaje a cada uno de los múltiples equipos de usuario, proporcionando el mensaje una indicación de la técnica de información seleccionada. También se divulgan una estación de base radial, una red móvil pública y un equipo de usuario adecuados para implementar el método.
