Abstract

Las realizaciones de la presente divulgación se refieren a un acceso aleatorio en un sistema de comunicación. Un primer dispositivo recibe un criterio para seleccionar un tipo de acceso aleatorio para realizar acceso aleatorio a un segundo dispositivo. El primer dispositivo determina adicionalmente si al primer dispositivo se le asigna un recurso de acceso aleatorio sin contención para un cuerpo tipo de acceso aleatorio, y a continuación realiza el acceso aleatorio al segundo dispositivo basándose en la determinación y basándose condicionalmente en el criterio. Como tal, en el caso donde se haya asignado el recurso de acceso aleatorio sin contención para un cierto tipo de acceso aleatorio, el dispositivo puede aplicar condicionalmente el criterio para selección del tipo de acceso aleatorio y puede por lo tanto realizar acceso aleatorio con eficacia mejorada.
