Abstract

Un método para operar un dispositivo de comunicación inalámbrica o un nodo de acceso de radio comprende direccionar recursos de sistema de varias subportadoras usando al menos una de múltiples numerologías diferentes disponibles dentro de una sola portadora, en donde las múltiples numerologías diferentes comprenden una primera numerología que tiene bloques de recursos con un primer ancho de banda y una primera separación de subportadora, ?f1, y una segunda numerología que tiene RBs con un segundo ancho de banda y una segunda separación de subportadora, ?f2, que es diferente de ?f1, y en donde la primera numerología está alineada en el dominio de frecuencia con respecto a una referencia de frecuencia, Fref, de acuerdo con m*?f1 + Fref, y la segunda numerología está alineada en el dominio de frecuencia en relación con la referencia de frecuencia, Fref, de acuerdo con n*?f2 + Fref, en donde m y n son enteros. El método comprende además transmitir y/o recibir información dentro de la portadora única de acuerdo con al menos una de las múltiples numerologías diferentes.
