对于C-V2X，30 MHz是否足够？
Is 30 MHz Enough for C-V2X?
摘要：
联网汽车不再是科幻小说中的未来梦想，但它们正在迅速占据人们日常生活的更大部分。实现互联车辆的关键技术之一是车联网通信（V2X）。尽管如此，美国（U.S.）联邦政府决定重新分配曾经专用于V2X用途的频谱带（即，“5.9GHz频带”），并且仅留下原始块的40%（即，30 MHz带宽）。这引发了人们对30 MHz频谱是否足以满足关键V2X安全信息和相应应用的担忧。我们对安全消息类型及其延迟要求进行了广泛的研究。然后，我们提出了我们的模拟结果，检查它们是否可以支持在30 MHz的频谱设置。
英文摘要：
Connected vehicles are no longer a futuristic dream coming out of a science fiction, but they are swiftly taking a bigger part of one's everyday life. One of the key technologies actualizing the connected vehicles is vehicle-to-everything communications (V2X). Nonetheless, the United States (U.S.) federal government decided to reallocate the spectrum band that used to be dedicated to V2X uses (namely, the ``5.9 GHz band'') and to leave only 40\% of the original chunk (i.e., 30 MHz of bandwidth) for V2X. It ignited concern of whether the 30-MHz spectrum suffices key V2X safety messages and the respective applications. We lay out an extensive study on the safety message types and their latency requirements. Then, we present our simulation results examining whether they can be supported in the 30-MHz spectrum setup.
