Abstract

Se describen un aparato y métodos para la señalización del índice de puertos. En una modalidad, un método para un nodo de red incluye generar al menos una indicación de puerto de una manera anidada por rango como no anidada por rango; y señalizar la al menos una indicación de puerto en una de las maneras anidada por rango como no anidada por rango. En otra modalidad, un método para un dispositivo inalámbrico (WD) incluye recibir al menos una indicación de puerto de un nodo de red, la al menos una indicación de índice de puertos que es recibida de una manera anidada por rango como no anidada por rango; y generar la retroalimentación de la información del estado del canal, CSI, en base al menos a una indicación de puerto.
