Abstract
En un sistema de comunicaciones inalámbricas, la informacion se comunica a través de un primer canal de comunicaciones que tiene un primer nivel deredundancia o de un segundo canal de comunicaciones que tiene un segundo nivel de redundancia sobre labase de determinacion de la calidad de las comunicaciones para uno de los canales, como mínimo. En formas de realizacion de acuerdo con la presente, las comunicaciones tienen lugar a través de un primer canal, porejemplo un canal estándar hasta queu na medida de la calidad de las comunicaciones para ese canal, como por ejemplo, la tasa de errores de bits o tasa deerrores de trama, satisface un criterio predeterminado. Cuando la calidad de las comunicaciones satisface el criteriopredeterminado, las comunicaciones pasana un canal robusto de alta penetracion que utiliza, sustancialmente, la misma cantidad de recursos espectrales que el primer canal, pero proporcionaredundancia significativamente aumentada. En otras formas derealizacion, una terminal, por ejemplo un radioteléfono celular u otra terminal de radio, seregistra en un sistema de comunicaciones mediante un canal de control de difusion estándar o un canal de control de difusion de alta penetracion, yconmutaentre ellos sobre la base de una determinacion de la calidad de las comunicaciones para el canal de control de difusion estándar. Por ejemplo, la terminalpuede conmutar a un canal de control de difusion de alta penetracion cuando no puedeadquirir el canal de control de difusion estándar en un área de recepcionque se encuentra en desventaja.
