Abstract

La tecnología presentada se refiere a un método, un método en un UE configurado con recepción discontinua, DRX, y un método en un nodo de red para la programación de DL del UE. El UE está configurado además con programación semipersistente, SPS, que otorga al UE una serie de oportunidades para la transmisión de UL. La SPS reduce la latencia en la transmisión de UL, mientras que puede tener un impacto negativo en la latencia en las transmisiones de DL. El nodo de red monitorea una recepción de datos de UL en cualquiera de los recursos de SPS otorgados al UE, se envía una asignación o concesión de activación en el PDCCH y al mismo tiempo se envía una información HARQ en respuesta a los datos de UL recibidos. La concesión/asignación de activación activa un temporizador de inactividad drx para que se ejecute en el UE, y que mientras se ejecuta el UE está DRX activo. Mientras el UE está DRX activo, el nodo de red puede programar una transmisión de datos de DL y enviar una asignación de DL y los datos de DL al UE. La tecnología presentada se refiere además a un UE que recibe una concesión/asignación de activación que activa un temporizador de inactividad drx para que se ejecute y, mientras se ejecuta, el UE es DRX activo. Mientras es DRX activo el UE una asignación de DL programa datos de DL en el PDSCH y que también son recibidos por el UE. Pueden seguir más asignaciones de DL antes de que el UE se convierta en DRX inactivo.
