Abstract

Las realizaciones incluyen métodos implementados por un equipo de usuario (EU) para transmitir o recibir una pluralidad de canales de datos físicos de una red inalámbrica. Dichos métodos incluyen la recepción, desde la red inalámbrica, de una indicación del estado de un Indicador de Configuración de Transmisión (ICT) que incluye uno o más pares de señal de referencia de (SR) fuente. Cada par de SR de fuente de cuasi colocación (QCL) se relaciona con los puertos de antenas, para las señales de referencia para demodulación (DM-SR), que están mapeadas a una pluralidad de grupos de multiplexación por división de código (CDM). Dichos métodos incluyen la recepción / transmisión de los canales de datos físicos según las reacciones de QCL para los pares de SR de fuente del estado de ICT indicado. Cada canal de datos físicos corresponde a un grupo de CDM y se recibe / transmite en asociación con la DM-SR con puertos de antenas mapeados al grupo CDM correspondientes. Otras realizaciones incluyen métodos complementarios implementados por una red inalámbrica, y los EU y las redes inalámbricas configuradas para implementar dichos métodos.
