论文摘要
在过去的几年中，已经开发了两种技术来使车辆之间直接交换信息。这些技术目前被视为替代方案，是欧洲通常提到的G5，以及Sidelink LTE-LET-VEHILLE到全部用途（LTE-V2X）（所谓的细胞-V2X，C-V2X的解决方案之一）。因此，注意力集中在比较它们上，并评论他们的优势和缺点以激发选择。不同的是，在这项工作中，我们专注于在同一区域和使用相同频率通道的情况下，而没有任何基础架构的帮助。我们的结果表明，在共同通道共存下，其G5的范围严重降解，而对LTE-V2X的影响是边缘的。此外，将CAM数据生成的缓解方法显示为定期间隔，以减少共同通道共存的影响，而对LTE-V2X的降解较少，甚至对LTE-V2X的改进也更少。
In the last few years, two technologies have been developed to enable direct exchange of information between vehicles. These technologies, currently seen as alternatives, are ITS-G5, as commonly referred in Europe, and sidelink LTE-vehicle-to-everything (LTE-V2X) (one of the solutions of the so-called cellular-V2X, C-V2X). For this reason, the attention has been mostly concentrated on comparing them and remarking their strengths and weaknesses to motivate a choice. Differently, in this work we focus on a scenario where both are used in the same area and using the same frequency channels, without the assistance from any infrastructure. Our results show that under co-channel coexistence the range of ITS-G5 is severely degraded, while impact on LTE-V2X is marginal. Additionally, a mitigation method where the CAM data generation is constrained to periodical intervals is shown to reduce the impact of co-channel coexistence, with less degradation on ITS-G5 performance and even improvement for LTE-V2X.
