ABSTRACT
The rapid increase of mobile data rates and the use of smartphones on board of trains present a challenge. Mobile Relay Nodes (MNRs) are a technology for High-Speed Railway (HSR) communications capable of improving the capacity of network. This paper provides a performance study for a communications architecture based on LTE evolved Node-B (eNB) and MRNs with Multi-Input Multi-Output (MIMO)-Beamforming capacity, deployed on HSR. It will be shown that a railway communication system with MIMO-Beamforming capacity offers significant improvements to the throughput achievable by on board users. Besides, the throughput of macro users located in cells where the train moves through is presented. The numerical results indicate that MIMO-Beamforming techniques have substantial benefits for the throughput of the MRN and on-board users.
