Advancements in Vehicular Communication Technologies: C-V2X and NR-V2X Comparison

Abstract

Cellular vehicle-to-everything (C-V2X) is one of the key enabling vehicular communication technologies endorsed by the vehicular industry, scientists, and researchers. Introduced by the 3GPP, LTE device-to-device in Release 12 evolved into C-V2X with mode 3 and mode 4. In mode 4, semi-persistent -scheduling-based sensing is performed by vehicles to select resources. However, when the density of vehicles increases, the performance of C-V2X mode 4 degrades. To address this challenge, 3GPP Release 16 introduced New Radio (NR) for V2X services, also known as NR-V2X. Modes 1 and 2 along with four additional sub-modes were considered in NR-V2X to achieve high reliability and higher throughput with low latency. This article discusses and evaluates the advancements introduced in NR-V2X by comparative analysis with C-V2X. To compare the performance, an NR-V2X simulator based on a network simulator (ns-3) for sub-6 GHz band is also introduced. In addition, feasible practical solutions to resolve resource selection problems are also discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
