Abstract
En las comunicaciones de multiplex de dominio de tiempo/acceso multiple de dominio de tiempo entre una estacion de base de unidad suscriptora, la estacion de base envía una señal de referencia. Una unidad suscriptora responde a con un paquete de datos (a) suficientemente corto para asegurara la correcta recepcion de la base sin importar el tiempo de transmision. La base determina el tempo de transmision tomado e instruye la unidad suscriptora para avanzar sus controles de tiempo de manera que paquetes de datos más grandes (b) pueden ser enviados para ser recibidos cuando se esperan. El ajuste de control de tiempo incluye un componente fijo dependiente de la separacion aproximada de la seccion de base y, un segundo componente a partir de la medicion del tiempo de transmision tomado.
