Abstract

La presente invención se refiere a un método realizado por un nodo de red (260, 500) en un sistema de comunicaciones inalámbricas (200). El método comprende generar (401) una señal de banda base de tiempo continuo aplicando una compensación de fase que remueve una rotación de fase dependiente del bloque de recursos físicos (PRB) sobre un subportador. El método comprende convertir (402) la señal de banda base de tiempo continuo generada en una señal de frecuencia de radio. El método comprende transmitir (403) la señal de frecuencia de radio a un dispositivo inalámbrico sobre una interfaz de radio.
