Abstract

In fifth generation (5G) networks one target is to provide very high capacity wireless access for the places where a lot of people consume a lot of data. Wireless communication is needed to provide access to high moving vehicles, however, extreme velocities must be taken into account in the design. Specific problems for air interface design to support extreme velocities are: high Doppler shifts, Inter-Carrier Interference (ICI), and difficulties in channel measurements needed for demodulation and hand-over measurements. Furthermore, very high data rates on outdoor macro cellular environment is challenging due to path loss. In high speed train (HST) deployments, the presence of line-of-sight connection enables the usage of wide bandwidths that are available on cmWave and mmWave spectrum. In this paper, we investigate the performance of mmWave single frequency network (SFN) in HST scenario. The performance of orthogonal frequency division multiplexing (OFDM) transmission with different new radio (NR) parameters is analyzed. Especially, the effect of Doppler and cyclic prefix (CP) is analyzed. Moreover, we conduct link level simulations and analyze the spectral efficiency in ideal HST scenario. Results show that it is possible to achieve very high data rates up to 10 Gbps.
