摘要:

本文提出了一种基于视觉的智能控制框架,用于动态无线环境中操作的移动开放式无线接入网络(O-RAN)基站(gNB)的智能控制。该框架包含三个创新组件:首先是在视觉增强的O-RAN架构中引入新的服务模型(SMs),称为VisionRAN,这些SMs通过传输基于视觉的传感数据和gNB位置控制消息扩展了最先进的O-RAN架构。其次是一个O-RAN xApp,称为VisionApp,它融合视觉和无线数据,并利用这些信息通过深度Q网络(DQN)控制移动gNB的位置。第三是一个数字孪生环境,称为VisionTwin,它整合了视觉数据并可以模拟现实无线场景;该数字孪生用于训练VisionApp中运行的DQN并验证整个系统。实验结果表明,使用真实视觉数据和模拟无线电获得的结果显示,所提出的方法相比静态gNB可将视线阻断时间减少高达75%。这些发现证实了在RAN中集成多模态感知和基于学习的控制的可行性。

英文摘要:

This paper proposes a vision-based framework for the intelligent control of mobile Open Radio Access Network (O-RAN) base stations (gNBs) operating in dynamic wireless environments. The framework comprises three innovative components. The first is the introduction of novel Service Models (SMs) within a vision-enabled O-RAN architecture, termed VisionRAN. These SMs extend state-of-the-art O-RAN-based architectures by enabling the transmission of vision-based sensing data and gNB positioning control messages. The second is an O-RAN xApp, VisionApp, which fuses vision and radio data, and uses this information to control the position of a mobile gNB, using a Deep Q-Network (DQN). The third is a digital twin environment, VisionTwin, which incorporates vision data and can emulate realistic wireless scenarios; this digital twin was used to train the DQN running in VisionApp and validate the overall system. Experimental results, obtained using real vision data and an emulated radio, demonstrate that the proposed approach reduces the duration of Line-of-Sight (LoS) blockages by up to 75% compared to a static gNB. These findings confirm the viability of integrating multimodal perception and learning-based control within RANs.
