Abstract

Se describe una estrategia para ahorro de batería con capacidad de respuesta al tráfico de datos para un dispositivo de equipo de usuario (UE) inalámbrico tal como un teléfono celular con capacidad de paquete de datos que incorpora transmisión y recepción discontinuas (DTX-DRX) flexibles cuando está en modo activo de evolución a largo plazo (LTE) como queda dictado por una red de acceso de radio (RAN) evolucionada tal como un nodo de base evolucionado (eNodo B). La duración del alargamiento de DRX y la reducción de requerimientos para sincronización de transmisiones de enlace ascendente da como resultados ahorros de energía de aproximadamente 75%, así como la creación de oportunidades para reducir interferencia y para asignar ranuras de tiempo adicionales para datos. Estos ahorros de energía son compatibles con otras propuestas de programación de enlace descendente, con Voz a través de IP (VoIP) sin canales de control, y no necesita elegir como blanco dispositivos de UE en condiciones de radio inadecuadas. Los dispositivos de UE de legado que pueden interactuar con el eNodo B mediante señalización de control de recursos de radio (RRC) siguen siendo compatibles.
