Abstract

Se describe un método para decidir en forma adaptiva el número de bloques de recursos de retroalimentación en un enlace descendente. El método incluye las siguientes etapas: una estación base (500) determina el modo que corresponde al número de bloques de recurso de retroalimentación que un equipo de usuario retroalimenta al monitorear el desempeño de una zona inalámbrica y el número de equipos de usuario; la estación base (500) transmite el modo al equipo de usuario (100) por señalización; el equipo de usuario (100) escucha al modo y decide en forma adaptiva el número de bloques de recursos de retroalimentación de acuerdo con su propio estado; el equipo de usuario (100) alimenta la información del indicador de calidad de canal de enlace descendente a la estación base (500) usando un algoritmo de retroalimentación con base en el número de indicadores de mejor calidad de canal o un algoritmo de retroalimentación a base de un umbral de indicadores de calidad de canal; finalmente, la estación base (500) lleva a cabo programación de recursos de acuerdo con la información de retroalimentación. La presente invención describe un método para decidir en forma adaptiva el número de bloques de recursos de retroalimentación con base en señalización de estación base y decisión de equipo de usuario, con respecto a un algoritmo de retroalimentación con base en el número de indicadores de mejor calidad de canal o un algoritmo de retroalimentación a base de un umbral de indicadores de calidad de canal en el enlace descendente, asegurando de esta manera el desempeño de la zona inalámbrica.
