Abstract

Se describen sistemas y métodos para determinar un primer indicador de control de enlace descendente (DCI) y un segundo DCI, determinar un conjunto de señales de referencia de información del estado de canal aperiódicas activas (A-CSI-RS) sobre la base del primer DCI y determinar un subconjunto del conjunto de A-CSI-RS activas sobre la base del segundo DCI. Una WTRU puede realizar silenciamiento de elemento de recurso RE sobre la base de un conjunto de A-CSI-RS activas. Una WTRU puede realizar la medición de la información del estado de canal (CSI) sobre la base de un subconjunto del conjunto de A-CSI*-RS activas.
