Abstract

Un procedimiento para enviar datos en un sistema de comunicación inalámbrica (100), que comprende: enviar, por un terminal de acceso, AT, (120a - 120i, 120x, 120y) primeros datos en un primer conjunto de sub-portadoras en un primer intervalo de tiempo (TCDMA) utilizando un primer esquema de modulación, en donde el primer conjunto incluye un número configurable de sub-portadoras; enviar, por el AT (120a - 120i, 120x, 120y), segundos datos en un segundo conjunto de sub-portadoras en un segundo intervalo de tiempo (TOFDMA) utilizando un segundo esquema de modulación diferente del primer esquema de modulación; y enviar, por el AT (120a - 120i, 120x, 120y), terceros datos en un tercer conjunto de sub-portadoras en el primer intervalo de tiempo (TCDMA) utilizando el segundo esquema de modulación, en donde los primer y tercer conjuntos incluyen diferentes sub-portadoras.
