Abstract

Un método, sistemas, y aparatos para reducir la latencia en transmisiones de LTE avanzado mediante el uso de tipos de recursos de intervalo de tiempo de transmisión corto (sTTI) y configuraciones de recurso de sTTI para transmisiones de latencia reducida. Además, puede describirse el diseño de un indicador de sTTI para la indicación dinámica de la presencia de recursos de sTTI y/o el tipo de recurso de sTTI. Las modalidades pueden incluir el manejo de la complejidad de la decodificación ciega de sPDCCH basada en el número de regiones de sPDCCH dentro de una ventana de sTTI. Pueden describirse configuraciones conjuntas del espacio de búsqueda de sPDCCH y PDCCH normal (nPDCCH). Puede describirse el control de la sobrecarga de la señal de referencia para sPDCCH/sPDSCH basado en el número de sTTI agrupados y/o uno o más parámetros de adaptación de enlace (p. ej. nivel de MCS). Puede describirse, además, un esquema de transmisión de sPDCCH y sPDSCH basado en sCCE.
