摘要:

开放无线接入网(O-RAN)引入了一种新兴的RAN架构,其实现了开放性、智能性和自动化控制。RAN智能控制器(RIC)提供了设计和部署RAN控制器的平台。xApp是将通过利用机器学习(ML)算法并以接近实时的运行来承担这一责任的应用程序。尽管这种新架构提供了机会,但基于人工智能(AI)的实用网络控制和自动化解决方案的进展缓慢。这主要是因为缺乏一个端到端的解决方案来设计,部署和测试基于AI的xApp,这些xApp在真正的O-RAN网络中完全可执行。在本文中,我们介绍了一个端到端的O-RAN设计和评估过程,并提供了一个详细的讨论,开发一个基于强化学习(RL)的xApp通过使用两种不同的RL方法,并考虑最新发布的O-RAN架构和接口。

英文摘要:

Open Radio Access Network (O-RAN) has introduced an emerging RAN architecture that enables openness, intelligence, and automated control. The RAN Intelligent Controller (RIC) provides the platform to design and deploy RAN controllers. xApps are the applications which will take this responsibility by leveraging machine learning (ML) algorithms and acting in near-real time. Despite the opportunities provided by this new architecture, the progress of practical artificial intelligence (AI)-based solutions for network control and automation has been slow. This is mostly because of the lack of an endto-end solution for designing, deploying, and testing AI-based xApps fully executable in real O-RAN network. In this paper we introduce an end-to-end O-RAN design and evaluation procedure and provide a detailed discussion of developing a Reinforcement Learning (RL) based xApp by using two different RL approaches and considering the latest released O-RAN architecture and interfaces.
