Abstract

Los niveles de potencia de transmisión de comunicación de enlace ascendente/enlace descendente están controlados en un sistema de comunicación inalámbrica. Una estación de recepción produce y provee información a un control de potencia de estación de transmisión en base a senales recibidas desde la estación de transmisión. Se obtiene una tasa de error de bloque medida (BLERmsr) a partir del número de bloques erróneos en una ventana deslizante de los últimos bloques de datos recibidos N, y se configuran ajuste de SIR en base a la BLERmsr y una BLER objetivo (BLERobjetivo). Una SIR objetivo de senales recibidas se ajusta de acuerdo con los ajustes de SIR.
