Abstract

Se proporcionan métodos, estaciones base y dispositivos inalámbricos para la indicación dinámica de recursos de información de estados de canal (CSI). De acuerdo con un aspecto, se proporciona un método para un dispositivo inalámbrico para determinar recursos de símbolo de referencia de información de estado de canal, CSI-RS, indicados por una estación base. El método incluye la determinación de un conjunto de recursos de CSI-RS con base en una indicación de una configuración de informes de CSI. La configuración de informes de CSI tiene una correspondencia biunívoca con un conjunto de recursos de CSI-RS.
