Summary:The coming 5G standard aims to support high mobility use cases where the user travels at high speeds in a car or a train. In this paper, measurement results are presented from high speed vehicle tests using a 5G radio access test system with beam tracking operating at a carrier frequency of 28 GHz. The tests were performed in a multi-transmission point deployment, where transmission point (TP) switching, beam tracking and operation at high vehicle speeds were successfully demonstrated. Beam tracking was demonstrated at a vehicle speed of 170 km/h while providing a downlink (DL) throughput of 3.6 Gbps. Furthermore, successful TP switching was demonstrated at vehicle speeds exceeding 160 km/h while maintaining a downlink bitrate of over 1 Gbps. Different user speeds show only a small impact in user throughput as long as the same beam is used.
