Abstract

Se proporcionan sistemas y métodos para activar una señal de referencia de información de estado de canal (CSI-RS) de potencia cero (ZP) semipersistente (SP). En algunas modalidades, un método llevado a cabo por un dispositivo inalámbrico para activar SP ZP CSI-RS incluye recibir, desde un nodo de red, un mensaje de control que indique la activación de uno o más recursos de SP ZP CSI-RS; y activar, con base en el mensaje de control, uno o más recursos de SP ZP CSI-RS. De esta forma, ZP CSI-RS se puede usar para la igualación de tasa alrededor de otros dispositivos inalámbricos y se puede activar un recurso de SP ZP CSI-RS sin activar ninguna medición de interferencia de CSI, (CSI-IM) de CSI-RS de potencia no cero (NZP), o notificación de CSI para el dispositivo inalámbrico.
