Abstract

Se proporcionan sistemas y métodos de señalización para la diversidad de canal compartido de enlace descendente físico (PDSCH). En algunas modalidades, un método llevado a cabo por un dispositivo inalámbrico para recibir una pluralidad de transmisiones de enlace descendente incluye determinar una asociación entre uno o más puertos de señal de referencia de desmodulación (DMRS) y uno o más valores de redundancia (RVs) asociados. El método también incluye recibir la pluralidad de transmisiones de enlace descendente usando la asociación. En algunas modalidades, esto permite usar una sola información de control de enlace descendente (DCI) para programar diferentes versiones de redundancia del mismo bloque de transporte desde los diferentes puntos de transmisión/recepción (TRPs), lo que ayuda a mejorar la confiabilidad de la decodificación de una transmisión con éxito dentro de estrictos requisitos de latencia.
