The 5G Cellular Downlink V2X Implementation Using V2N With Spatial Modulation

Abstract

Fifth generation (5G) New Radio (NR) technology provides cellular vehicle-to-everything (C-V2X) communication. The 5G NR will utilize the existing uplink (UL) and downlink (DL) to furnish vehicle-to-network (V2N) communication via the cellular network. The new technology provides the enhanced throughput, edgeless connectivity, high reliability and the reduced latency for 5G DL V2X. With significantly reduced latency of NR, this paper shows that C-V2X can be implemented via 5G V2N communication. Spatial modulation is a good candidate to support unicast and groupcast for V2X services. We also discuss keyless security of 5G NR using physical layer security. The security of 5G NR can be implemented employing spatial modulation (SM) for unicast and groupcast in millimeter-wave (mmWave) communications with multiple-input and multiple-output (MIMO) channels.
