Abstract

Se proporcionan sistemas y métodos para la señalización de la diversidad del Canal físico compartido de enlace descendente (PDSCH). En algunas realizaciones, un método realizado por un dispositivo inalámbrico para recibir una pluralidad de transmisiones de enlace descendente incluye determinar una asociación entre uno o más puertos de Señales de referencia de demodulación (DMRS) y uno o más Valores de redundancia (RV) asociados. El método también incluye recibir la pluralidad de transmisiones de enlace descendente utilizando la asociación. En algunas realizaciones, esto permite utilizar una única 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 (TRP), lo que ayuda a mejorar la confiabilidad en la decodificación de una transmisión exitosamente dentro de los estrictos requisitos de latencia.
