Lorsque la station de base planifie, pour le premier terminal, une instruction de planification transportant des informations d'indication de ressource, le second terminal peut également écouter l'instruction de planification. Lorsque le premier terminal envoie des données au second terminal, le premier terminal n'a pas besoin de transmettre des informations de planification au second terminal et le second terminal n'a pas besoin d'effectuer une détection aveugle sur SA. Par conséquent, des retards manuels peuvent être réduits et, puisque le processus de transmission d'informations de planification est omis, des surdébits sont fortement réduits.
