The average sum rate comparison versus \(R_{th}\). Different QoS can detect the stability of the algorithm. When a certain value is reached, the algorithm starts to converge. The x-axis is \(R_{th}\), and the y-axis is the average sum rate. The illustrations are the USDPA, AU + DQN, RU + DQN, AU + AP, US + AP
