- Abstract
- It is one of important 5G applications of 3GPP New Radio (NR) to provide high data rate services including HD video streaming or high speed Internet access on smartphone in a high speed train (HST). However, the current NR specification is not enough to satisfy QoS for the services in the HST scenario. In this paper, we evaluate NR system, and also provide the enhancements of physical layer aspects of NR system which includes demodulation reference signal pattern, resource element mapping, and numerology in order to improve the quality of high data rate services in the HST scenario. Link level simulations are used to supplement our considerations for the enhancements.
