Abstract

Se desvela tecnología para descarga de tráfico para generar una subtrama flexible de baja interferencia (FlexSF) de una configuración de subtrama de duplexación por división de tiempo (TDD) de enlace ascendente-enlace descendente (UL-DL) adaptativa en una red heterogénea (HetNet). Un procedimiento puede incluir un Nodo B evolucionado (eNB) que monitoriza una métrica de carga de tráfico para una condición de carga de tráfico especificada. El eNB puede descargar tráfico planeado para un paquete de un equipo de usuario (UE) macro desde una macrocélula hasta una FlexSF de una configuración de subtrama de UL-DL de una célula pequeña cuando existe la condición de carga de tráfico especificada. El eNB puede ser un macro eNB de la macrocélula o un eNB pequeño de la célula pequeña.
