Abstract

En una disposición de ejemplo, una estación base (16) que sirve a un dispositivo inalámbrico (14), controla el tiempo de activación para la transmisión por parte del dispositivo inalámbrico (14) de señales de referencia de sondeo (SRS) aperiódicas o semipersistentes, pero tiene en cuenta una recomendación de tiempo de activación realizada por un servidor de ubicación (20) con el que la estación base de servicio (16) proporciona su información de tiempo. La disposición permite que el servidor de ubicación (20), que tiene una vista de la línea de tiempo general, recomiende un tiempo de activación mientras deja a la estación base de servicio (16) en control del tiempo de activación, que comparte la estación de base de servicio (16) con el servidor de ubicación (20). A su vez, el servidor de localización (20) utiliza el tiempo de activación para configurar estaciones base vecinas (16), por ejemplo, para la recepción coordinada de SRS, para posicionar el dispositivo (14) mediante determinaciones de diferencia horaria observada de llegada (UTDOA) de enlace ascendente. La activación de la SRS proporciona, por ejemplo, una mayor densidad de SRS en comparación con cualquier transmisión SRS periódica en curso realizada por el dispositivo inalámbrico (14).
