Abstract
Se describen modalidades de métodos para proporcionar detección de cambio de avance de sincronización. En algunas modalidades, un método llevado a cabo por un dispositivo inalámbrico para determinar la validez de una configuración de avance de sincronización del dispositivo inalámbrico para una transmisión en modo inactivo comprende obtener, mientras el dispositivo inalámbrico está operando en un modo conectado, un valor de avance de sincronización para el dispositivo inalámbrico. El método comprende además pasar del modo conectado a un modo inactivo y llevar a cabo una medición en una o más células de servicio del dispositivo inalámbrico mientras el dispositivo inalámbrico está en el modo inactivo. El método también comprende determinar si el avance de sincronización es válido para una transmisión en modo inactivo en función de la medición. En algunas modalidades, la medición puede ser una medición de intensidad de señal tal como, por ejemplo, una medición de potencia recibida de señal de referencia y/o una medición de calidad de señal tal como, por ejemplo, una medición de calidad recibida de señal de referencia.
