基于开放和智能的原则，运营商们在全球范围内齐心协力致力于增强无线接入网（RAN）架构。其目标是在开放硬件上构建由运营商定义的RAN架构（以及相关接口），为超五代（5G）以及未来的六代（6G）无线网络提供智能无线控制。具体而言，开放无线接入网（O - RAN）联盟通过合并xRAN论坛和C - RAN联盟而成立，以正式确定有助于实现这一目标的要求。鉴于O - RAN在当前无线领域的重要性，本文介绍了O - RAN联盟所规定的开放RAN的概念、原则和要求。为了说明智能在O - RAN中的作用，我们提出了一种智能无线资源管理方案来处理交通拥堵，并在从一家大型运营商获取的真实数据集上证明了其有效性。还讨论了符合O - RAN要求的这种部署场景的高层架构。文章最后指出了未来研发的关键技术挑战和未解决的问题。
Building on the principles of openness and intelligence, there has been a concerted global effort from the operators towards enhancing the radio access network (RAN) architecture. The objective is to build an operator-defined RAN architecture (and associated interfaces) on open hardware that provides intelligent radio control for beyond fifth generation (5G) as well as future sixth generation (6G) wireless networks. Specifically, the open-radio access network (O-RAN) alliance has been formed by merging xRAN forum and C-RAN alliance to formally define the requirements that would help achieve this objective. Owing to the importance of O-RAN in the current wireless landscape, this article provides an introduction to the concepts, principles, and requirements of the Open RAN as specified by the O-RAN alliance. In order to illustrate the role of intelligence in O-RAN, we propose an intelligent radio resource management scheme to handle traffic congestion and demonstrate its efficacy on a real-world dataset obtained from a large operator. A high-level architecture of this deployment scenario that is compliant with the O-RAN requirements is also discussed. The article concludes with key technical challenges and open problems for future research and development.
