Abstract	Along with the wide deployment of high-speed railway at more than 300 km/h, providing various services effectively for users in the train becomes both practical demand and interesting challenge for wireless communication. Due to the specific environment for high-speed railway, existing radio admission control (RAC) algorithms could not suit the requirements such as frequent handover, quick decision-making duration and fast-changing physical transmission condition. The investigation on novel and proper RAC is of great importance. In this paper, we propose an effective radio admission control scheme based on Rician shading model for high-speed railway communication with MIMO antennas. Layered networks access architecture is designed in which Rician channel is used to analyze physical transmission condition. The effect of bit error rate on data rate at high moving speeds is taken into account for the RAC decision-making to get better quality of service (QoS). Moreover, different priorities for different services are considered to resolve simultaneous multiple users' access requests. Simulation results have proved that the proposed scheme may improve QoS obviously compared to the scheme that does not consider bit error rate and service priority.
