Abstract

Se proporcionan un método y aparato para transmitir tramas que tienen un campo de señalización (SIG) para un segundo tipo de estación (STA) en un sistema de comunicación inalámbrica. Para esto, STA prepara una trama que tiene una primera parte para un primer tipo de STA y una segunda parte para el segundo tipo de STA. Aquí, la segunda parte incluye un primer campo de señalización (HE-SIG A) para información de control común y un segundo campo de señalización (HE-SIG B) para la señalización de información que comprende información de control específico del usuario. En cuanto al segundo campo de señalización, la información de señalización independiente para el segundo campo de señalización (HE-SIG B) ha de ser transmitida para cada ancho de banda de 20 MHz dentro de un primer ancho de banda de 40 MHz. Y la información de señalización del primer ancho de banda de 40 MHz se duplica en un segundo ancho de banda de 40 MHz, cuando la trama se va a transmitir en un ancho de banda igual o superior a 80 MHz. La STA transmite esta trama preparada para una o más STA.
