Abstract

La presente se refiere a la recuperación eficiente de datos de Acceso de Paquete de Enlace Descendente de Alta Velocidad (HSDPA) seguido de transferencia. La presente divulga un método y sistema para que el equipo de usuario (UE) lleve a cabo una serie de acciones para reducir la latencia y evitar, potencialmente, la pérdida de transmisión PDU durante el procedimiento de cambio de célula HS-DSCH en servicio. Se presenta un nuevo criterio para que el UE genere el informe de estado de RLC PDU. El UE genera el informe de estado de las PDUs tan pronto como le es posible, seguido de la notificación del cambio de célula HS-DSCH indicado por el procedimiento RRC para recuperar más eficientemente los datos almacenados del Nodo B fuente. El estado de la PDU puede ser senalizado para cada instancia de AMRLC asociada con el canal de transporte de HS-CSCH. Además, ante el cambio de célula de HS-DSCH en servicio del Inter-Nodo B, el SRNC puede esperar el informe de estado de la PDU antes de iniciar la transmisión de datos nuevos en la célula objetivo. También se divulga un equipo de usuario para facilitar el cambio de célula de canal compartido de enlace descendente de alta velocidad.
