Abstract

Se proporcionan mecanismos para la sincronización en una red de comunicación inalámbrica. Un método se realiza por un dispositivo de transmisión. El método comprende transmitir una primera señal de sincronización en un primer recurso de tiempo/frecuencia en una rejilla de tiempo/frecuencia. El método comprende recibir una respuesta a la primera señal de sincronización de un dispositivo de recepción. El método comprende transmitir una segunda señal de sincronización en un segundo recurso de tiempo/frecuencia en la rejilla de tiempo/frecuencia al dispositivo de recepción, en donde el segundo recurso de tiempo/frecuencia abarca una porción más larga de la rejilla de tiempo/frecuencia que el primer recurso de tiempo/frecuencia.
