Positioning of High-speed Trains using 5G New Radio Synchronization Signals [PDF]

open access: yes, 2018
We study positioning of high-speed trains in 5G new radio (NR) networks by utilizing specific NR synchronization signals. The studies are based on simulations with 3GPP-specified radio channel models including path loss, shadowing and fast fading effects.
