Abstract
Varias modalidades de la presente invención proporcionan un método para acceso aleatorio. El método que puede ser llevado a cabo por un dispositivo terminal comprende recibir, desde un nodo de red, información que indique una asociación entre una transmisión de enlace descendente y una transmisión de enlace ascendente (por ejemplo, una asociación entre una señal de sincronización y un bloque de canal de transmisión físico y una ocasión de canal compartido) en un procedimiento de acceso aleatorio. La asociación se basa, al menos en parte, en la configuración de recurso de acceso aleatorio (por ejemplo, una ocasión de acceso aleatorio) y recurso de canal compartido (por ejemplo, la ocasión de canal compartido) para un mensaje de enlace ascendente (por ejemplo, que incluya un preámbulo y datos de canal compartido de enlace ascendente físico) en el procedimiento de acceso aleatorio. De acuerdo con las modalidades de la presente invención, una asociación entre una señal de sincronización y un bloque de canal de transmisión físico y una ocasión de canal compartido en un procedimiento de acceso aleatorio se pueden configurar de manera flexible y eficiente.
