Abstract

Un método para transmitir una trama de datos en un sistema de comunicación inalámbrico comienza creando una ventana de tiempo de llegada (TOA), que incluye un inicio de ventana (WS) y un final de ventana (WE). Se determina el TOA de la trama de datos en la interfase de aire para su transmisión, y se toma una acción adicional según el momento en que llegue la trama de datos relativa a la ventana TOA. La trama de datos bufferizada si el TOA está antes del WS. La trama de datos es transmitida si el TOA está dentro de la ventana TOA. La trama de datos es descarga si el TOA está después del WE.
