The NSCUs comparison versus \(R_{th}\). Under different QoS conditions, the more users are successfully decoded, the more effective users are accessed. Then the algorithm performance is better. The x-axis is the \(R_{th}\), and the y-axis is the NSCUs. The illustrations are the USDPA, AU + DQN, RU + DQN, AU + AP, US + AP
