Speech Title: Holistic Network Virtualization: AI-Native 6G

Abstract: With the commercialization of 5G communication networks, the global telecommunication community has shifted its focus to R&D for 6G networks. To support disruptive new applications along with growing service demands, it is envisioned that 6G will require agile network architectures in the presence of network dynamics, intelligent network management to address complexity due to extreme connectivity, and customized service provision to meet diverse service requirements. In this presentation, we will discuss potential ideas and solutions towards intelligent network architectures and flexible network management. First, we will briefly introduce network slicing and digital twin, and present how network slicing and digital twin can support flexible network management, taking advantage of advances in artificial intelligence. Then, we will focus on potential realization of intelligent network architectures, followed by our recent work on digital twin empowered resource allocation for collaborative sensing as a case study.

Speech Title: Fast Adaptation for Deep Learning based Wireless Communications

Abstract: The integration with artificial intelligence (AI), especially deep learning (DL), is recognized as one of the six usage scenarios in next-generation wireless communication. In this talk, we first provide a brief overview on DL for wireless communications in the past around 10 years and present several critical challenges hinder the widespread applications of DL techniques in wireless communications. Since the existing DL-based wireless communications struggle to address the dynamic environments, we then discuss fast adaptation for DL-based wireless communications by using the few-shot learning (FSL) techniques. After identifying the difference between fast adaptation in wireless communications and traditional AI tasks, we outline two design requirements for applying FSL techniques to wireless communications and provide a comprehensive discussion on FSL techniques in wireless communications that satisfy these two design requirements. In particular, we emphasize the crucial role of domain knowledge in achieving fast adaptation. At the end of this talk, we highlight several open issues for future research.

Speech Title: User-centric distributed massive MIMO for the ultimate cellular communication system

Abstract: As the high data rate communication services proliferate in mobile communications, there is a demand for very high peak data rates in excess of Gbps is demanded, while the available radio bandwidth is limited. To achieve this goal, we need to improve the spectrum efficiency further and expand the transmission bandwidth. In 5G systems, the mmWave band has been allocated. However, mmWave signals have high pathloss and rectilinear propagation characteristics, resulting in short communication distances and frequent blockages caused by obstacles such as buildings. The utilization of distributed massive MIMO, also known as a cell-free system, is an effective approach to significantly improve spectrum efficiency. This approach turns the disadvantages of the mmWave band into advantages. User-centric ultra-small virtual cells or user-clusters are formed based on user location information, realizing the ultimate cellular system. The same frequencies are reused in all user-clusters. The small-scale multiuser distributed MIMO with interference suppression is simultaneously performed in all user-clusters. In this presentation, we will discuss the system architecture of a user-centric distributed massive MIMO system and share recent performance evaluation results.

Speech Title: Wireless LLM Inference within the Framework of AI-Native NetGPT

Abstract: Large language models (LLMs) have triggered tremendous success to empower information generation and inference. Towards personalized generative inference, a collaborative cloud-edge-terminal methodology is promising, as it facilitates the effective orchestration of heterogeneous distributed communication and computing resources.
Recently, we have put forward NetGPT (Network-enabled Generative Pre-Trained Transformer), to capably synergize appropriate LLMs at the edge, user equipment (UE), and cloud based on their different computing capacities. Edge and terminal LLMs could efficiently leverage location-based information for personalized prompt completion, thus benefiting the interaction with the cloud LLM.
Also, this talk will highlight the essential changes required for an artificial intelligence (AI)-native network architecture towards NetGPT, with emphasis on deeper integration of communications and computing resources and careful calibration of logical AI workflow.
Furthermore, toward efficient wireless LLM inference in edge computing, this talk will analyze the impact of different splitting points in mainstream open-source LLMs. On this basis, this talk introduces a framework taking inspiration from model-based reinforcement learning (MBRL) to determine the optimal splitting point across the edge and user equipment. By incorporating a reward surrogate model, the proposed approach significantly reduces the computational cost of frequent performance evaluations. Extensive simulations demonstrate that this method effectively balances inference performance and computational load under varying radio accessing conditions, providing a robust solution for LLM deployment in decentralized settings.
