Cellular vehicle-to-everything (C-V2X) was introduced to support autonomous driving through 5G and beyond networks. C-V2X leverages cellular network infrastructure to integrate vehicle-to-network, vehicle-to-pedestrian, vehicle-to-infrastructure, and vehicle-to-vehicle communications. It has been suggested that Open RAN can be used to achieve the latency requirements essential to realize C-V2X as it achieves real-time optimization through the use of AI in Near real-time RAN Intelligence Controller (Near-RT RIC). The Open RAN will allow the access to historical traffic data or acquisition of data from vehicles. The data will then be transferred to Near-RT RIC for detecting network anomalies while maintaining reliable communication, which is essential for realizing autonomous driving. Open RAN also supports non-real-time RAN intelligent controller (Non-RT RIC) that allows more complex ML workflows such as policy-based feature extraction and optimization to guide vehicles when real-time acquisition is not available. Open RAN provides support for edge cloud, i.e. Open Cloud that helps to interface the Near-RT RIC with Open RAN central unit's user and control plane. Together, the Open RAN and C-V2X are considered to be the key-enabling technologies for achieving low-latency in autonomous vehicular communication networks. The issue attracted over 100 high-quality submissions from all over the world, among which 12 original contributions were eventually selected for publication. The novelty and key contributions of these articles are summarized as follows.

客座社论介绍开放式无线电接入网络特别章节：车载网络中的架构、挑战、机遇和用例


蜂窝车联网 (C-V2X) 的推出是为了通过 5G 及其他网络支持自动驾驶。 C-V2X 利用蜂窝网络基础设施来集成车辆到网络、车辆到行人、车辆到基础设施以及车辆到车辆通信。有人建议，Open RAN 可用于满足实现 C-V2X 所必需的延迟要求，因为它通过在近实时 RAN 智能控制器（Near-RT RIC）中使用 AI 来实现实时优化。 Open RAN 将允许访问历史交通数据或从车辆获取数据。然后，数据将传输到Near-RT RIC，用于检测网络异常，同时保持可靠的通信，这对于实现自动驾驶至关重要。 Open RAN 还支持非实时 RAN 智能控制器 (Non-RT RIC)，该控制器允许更复杂的 ML 工作流程，例如基于策略的特征提取和优化，以在实时采集不可用时指导车辆。 Open RAN 提供对边缘云的支持，即有助于将 Near-RT RIC 与 Open RAN 中央单元的用户和控制平面连接起来的开放云。 Open RAN 和 C-V2X 一起被认为是实现自主车辆通信网络低延迟的关键支持技术。该期吸引了来自世界各地的100多篇高质量投稿，其中12篇原创稿件最终被选中出版。这些文章的新颖性和主要贡献总结如下。
