Abstract
Las modalidades de la presente describen aparatos, sistemas y métodos para señalización para soportar comunicaciones de puntos múltiples coordinados (CoMP) de enlace descendente con un equipo de usuario (UE) en una red de comunicación inalámbrica. En algunas modalidades, la UE puede estar configurada con una pluralidad de procesos de información del estado del canal (CSI) (por ejemplo, por medio de señales de control de recursos vía radio (RRC) para uso en proporcionar realimentación de CSI a un nodo B evolucionado (eNB) para que soporte comunicaciones de CoMP de enlace descendente. El UE puede estar configurado con una pluralidad de series de procesos de CSI. El UE puede recibir además un mensaje de información de control de enlace descendente (DCI) desde el eNB que indique uno de las series configuradas de procesos de CSI por los cuales el UE va a proveer realimentación de CSI al UE. El UE puede generar la realimentación de CSI para la serie indicada de procesos de CSI y trasmitir la realimentación de CSI al eNB, en un informe de CSI.
