Abstract

Se dan a conocer sistemas y métodos para validar un mensaje de control para la activación o desactivación de notificación de información de estado de canal semi-persistente (SP-CSI) en un sistema de comunicación inalámbrica. En algunas modalidades, un método llevado a cabo por un dispositivo inalámbrico para validar un mensaje de control para la activación o desactivación de notificación de SP-CSI en un sistema de comunicación inalámbrica comprende recibir, desde un nodo de red, un mensaje de control para la activación o desactivación de la notificación de SP-CSI. El método comprende además llevar a cabo, con base en el mensaje de control, una determinación sobre si activar la notificación de SP-CSI o desactivar la notificación de SP-CSI, y activar o desactivar la notificación de SP-CSI de acuerdo con la determinación. De esta manera, el dispositivo inalámbrico está habilitado para distinguir entre un mensaje de control que active la notificación de SP-SCI y un mensaje de control que desactive la notificación de SP-SCI.
