Abstract

Esta solicitud proporciona un método de transmisión de PPDU y un aparato relacionado. El método incluye: generar una PPDU, donde la PPDU incluye un campo de señal universal U SIG, y el U-SIG incluye un subcampo que indica que la PPDU es un paquete de datos nulo NDP; y enviar la PPDU. De esta manera, un Bfee que recibe el NDP puede identificar el NDP con anticipación. Esto ayuda a mejorar la eficiencia de la lectura del NDP por el Bfee. La PPDU es un NDP utilizado para un estándar después de 802.11ax. En un escenario en el cual se ejecuta comunicación inalámbrica utilizando el estándar (por ejemplo, 802.11be) después de 802.11ax, el Bfee puede ejecutar estimación de canal con base en el NDP.
