Abstract

La estación de base receptora controla el error de sincronización horaria de la trama de acceso múltiple por división horaria (TDMA) correspondiente alas comunicaciones de ráfaga de estaciones móviles transmitidas en el canal de controldigital hacia atrás. La estación de base prepara luego una funciónde densidad de probabilidades, que refleja la cantidad de casos de cada una de determinada longitud de errores de sincronización horaria, controlados a lolargo de un período detiempo pre determinado. La función de densidad de probabilidades se procesa para idenficiar el porcentaje de comunicaciones deráfaga durante ese período de tiempo predeterminado que exceden un umbral de errores. Si el porcentajedeterminado excede un porcentaje dado, la estaciónde base ordena el modo de operación de comunicación de ráfaga de longitud abreviada. El error de sincronización horaria medido se procesacontinuamente para efectuar el control dinámico respectode la longitud especificada de las comunicaciones de ráfaga de estaciones móviles.
