Abstract

a presente invenção refere-se a um método implementado por uma unidade de fronthaul sem fio, o método compreende agregar uma pluralidade de primeiros sinais de canal sem fio para produzir um primeiro sinal agregado através de mapeamento de domínio de frequência digital (fdm), em que os primeiros sinais de canal sem fio estão posicionados no primeiro sinal agregado em primeiras bandas de frequência não sobrepostas, cada primeira banda de frequência não sobreposta tendo uma primeira largura de banda e uma frequência central, em que cada respectiva frequência central é um inteiro ímpar múltiplo de uma frequência central mais baixa, converter o primeiro sinal agregado em um primeiro sinal modulado, e transmitir o primeiro sinal modulado para uma conexão de fronthaul sem fio
