摘要：

In this paper, performance evaluation and system level simulation have been done for the communication between the base station and train users, macro users. And an improved proportional fair algorithm has been proposed to ensure that train users are prioritized to get the resources and differentiate service priority transmission. By using this algorithm, train users will access to resources first. Under this premise, the service with higher priority will be assigned to resources preferentially. The simulation results show the proposed algorithm can improve the performance of the train users, as well as which of the service with a higher priority by the simulator.
