Abstract

Un método y aparato en un sistema de comunicaciones de radio (100, 101) proporciona canales de control de transmision simultánea para un área de cobertura (500) y canales de mensajes transmitidos en zonas de cobertura (502) dentro del área de cobertura (500) sobre una base de mulplexion por division de tiempo (Fig.4). Una primera técnica de modulacion genera (814, 816, 818) cada uno de los canales de mensajes a una primera potencia de salida promedio menor que una potencia de salida pico de un transmisor (202). Una segunda técnica de modulacion genera (806,808,810) cada uno de los canales de control a una segunda potencia de salida promedio aproximadamente igual a la potencia de salida pico del transmisor (202), aumentando así la distancia de cobertura utilizable desde el transmisor (202) para el canal de control comparado con el canal de mensajes. Los canales de control se distribuyen (Fig. 5) en las zonas de cobertura (502) en un patron geográfico escalonado de manera tal que la recepcion de los canales de control se mantiene sustancialmente en todo el área de cobertura (500).
