Abstract

La presente invención se refiere a un sistema de comunicación radio digital para utilizarse con radios digitales, caracterizado porque comprende: una pluralidad de celdas, cada una de las cuales incluye una estación base que tiene un transmisor y un receptor para proporcionar comunicación radio-digital bidireccional con dichos radios digitales, la estación base de cada una de las celdas comunican con los radios digitales usando marcos de comunicación que tienen por lo menos un intervalo de comunicación de entrada y un intervalo de comunicación de salida a fin de comunicarse con los radios digitales, por lo menos un intervalo de entrada es utilizado por el receptor de la estación base para recibir información de uno de los radios digitales y por lo menos un intervalo de salida es utilizada por el transmisor de la estación base para transmitir información a por lo menos uno de los radios digitales, los marcos de comunicación de cada de la pluralidad de celdas son uniformes en longitud, una primera de dichas celdas tiene un regimen de datos del transmisor de la estación base que difiere de por lo menos del regimen de datos del transmisor de la estación base de una segunda celda.
