Radio Admission Control Scheme for High-Speed Railway Communication With MIMO Antennas
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, the authors propose an effective radio admission control scheme based on Rician shading model for high-speed railway communication with MIMO antennas.
