Abstract

Una unidad inalámbrica de transmision/recepcion (WTRU) utiliza un oscilador que provee exactitud para parámetros de comunicaciones sincronizadas en un modo activo, y opera a potencia reducida durante un modo de recepcion discontinua (DRX). Un reloj de tiempo real (RTC) es utilizado como estándar de frecuencia durante la operacion de potencia reducida, y se efectua un ajuste de frecuencia mientras que el RTC es utilizado como el estándar de frecuencia. Al efectuar el ajuste de frecuencia, el RTC es capaz de ser utilizado como el estándar de frecuencia para períodos de tiempo sustanciales, reduciendo así el consumo de potencia de la WTRU durante el modo DRX.
