The evolution of generative artificial intelligence (GenAI) constitutes a turning point in reshaping the future of technology in different aspects. Wireless networks in particular, with the blooming of self-evolving networks, represent a rich field for exploiting GenAI and reaping several benefits that can fundamentally change the way how wireless networks are designed and operated nowadays. To be specific, large GenAI models are envisioned to open up a new era of autonomous wireless networks, in which multi-modal GenAI models trained over various Telecom data, can be fine-tuned to perform several downstream tasks, eliminating the need for building and training dedicated AI models for each specific task and paving the way for the realization of artificial general intelligence (AGI)-empowered wireless networks. In this article, we aim to unfold the opportunities that can be reaped from integrating large GenAI models into the Telecom domain. In particular, we first highlight the applications of large GenAI models in future wireless networks, defining potential use-cases and revealing insights on the associated theoretical and practical challenges. Furthermore, we unveil how 6G can open up new opportunities through connecting multiple on-device large GenAI models, and hence, paves the way to the collective intelligence paradigm. Finally, we put a forward-looking vision on how large GenAI models will be the key to realize self-evolving networks.

A. Large Language Models for Sensing

Large-GenAI-Models are proposed for wireless sensing tasks that combine RF and visual information, including 3D environment reconstruction and multimodal localization.

  • 1) 3D Wireless Imaging:: Deep-learning sensing schemes map RF data to 2D images for localization, remote sensing, and resource allocation but lack generalizability and require substantial labeled data.
  • 1) 3D Wireless Imaging:: Models such as DALL-E3, CLIP, Vector Quantized GAN, and GPT-4V illustrate visual GenAI approaches for generating or relating images and text.
  • 1) 3D Wireless Imaging:: Visual GenAI models are envisioned to generate super-resolution 3D images of wireless environments from measured wireless data.
  • 1) 3D Wireless Imaging:: These 3D reconstructions can provide contextual and situational awareness for beamforming, handover, and resource allocation by relating RF signals to environmental features.
  • 2) Super-Resolution Localization:: Accurate localization supports network optimization, resource allocation, and QoS, but vision-based methods face limited field of view, calibration, alignment, and multimodal-fusion bottlenecks.
  • 2) Super-Resolution Localization:: Large-GenAI-Models are envisioned to integrate multimodal data to capture environmental, temporal, and situational information for high-precision localization.

B. Large Language Models for Transmission

High-frequency wireless communication suffers from blockage, beam misalignment, and signal degradation, motivating Large-GenAI-Models for beam prediction using multimodal network information.

  • mmWave and THz systems face severe signal degradation because their lossy, highly directional transmissions are sensitive to blockage and beam misalignment.
  • Large-GenAI-Models pretrained on beamforming scenarios are envisioned to predict beams that maximize signal strength and minimize interference.
  • Multimodal information about blockage probability, user status, and activities can support prediction of the optimum beam in dynamic network conditions.

2) Frequency Division Duplexing (FDD) Transmission:

In FDD systems, CSI is acquired separately across uplink and downlink, creating resource and latency costs that become especially challenging for massive MIMO. Large-GenAI-Models are envisioned to use partial uplink CSI and multimodal network information to support downlink estimation and beamforming.

  • The proposed FDD beamforming use case centers on applying Large-GenAI-Models to beamforming in FDD systems.
  • Separate uplink and downlink CSI acquisition in FDD consumes network resources and introduces high latency, especially for massive MIMO.Partial uplink CSI can instead be used to extrapolate full downlink CSI.
  • Large-GenAI-Models can exploit self-attention and generative capabilities to capture relationships between uplink and downlink transmissions for CSI estimation.

III. WIRELESS FOR LARGE-GENAI-MODEL

6G can connect multiple on-device Large-GenAI-Models into a collective-intelligence fabric that moves knowledge rather than raw data. This requires semantic abstraction and topological representations to reduce communication while supporting reasoning across domains.

  • 6G is envisioned as a computing fabric that moves knowledge among wireless devices, extending cloud-trained Large-GenAI-Models toward distributed collective intelligence.
  • Semantic compression and abstraction are needed because raw-data-based Large-GenAI-Models can impose substantial computation overhead and communication redundancy.
  • Knowledge represented with graphs, simplices, cells, or complexes can reduce transmitted data while supporting logical reasoning across domains.

2) Emergent protocol learning:

GenAI-powered devices require adaptable, autonomous, goal-oriented protocols because application-specific 5G protocols are inflexible for diverse use cases. Multi-agent learning and autonomous agents are proposed to support collaboration, planning, reasoning, and control.

  • 2) Emergent protocol learning: GenAI use cases require adaptable, autonomous, goal-oriented protocols because conventional 5G protocols are inflexible across diverse applications.
  • 2) Emergent protocol learning: Multi-agent reinforcement learning can learn semantic languages that determine when, where, and what information agents should deliver.
  • 2) Emergent protocol learning: Multi-agent learning can support goal-oriented, compositional, and grounded wireless MAC and network-layer protocols.
  • 2) Emergent protocol learning: Autonomous agents can perceive environments, plan tasks, memorize experiences, evaluate actions, and enable network and device control without human intervention.Cloud-based Large-GenAI-Models can guide wireless agents as world models using common-sense knowledge.

B. Use Cases of Collective Intelligence

Collective intelligence enables distributed GenAI agents to support intent-driven networking and autonomous-vehicle coordination. The envisioned mechanisms include distributed planning, semantic V2X communication, cooperative perception, and model-guided multi-agent control.

  • Intent-driven networking: Distributed GenAI agents can decompose high-level network intents into actionable tasks, configure systems, and memorize experience for future operation.
  • Intent-driven networking: Communication among network-device agents can reduce reliance on centralized control and lower control-plane signaling load.
  • Autonomous vehicles: In autonomous vehicles, semantic V2X communication and emergent data-plane protocols can improve transmission efficiency, latency, and reliability compared with 5G raw-perception and control-command delivery.
  • Autonomous vehicles: Cooperative perception and control using Large-GenAI-Model-guided multi-agent reinforcement learning or games can improve traffic flow and safety.

B. Distributed GPT

Distributed GPT is presented as a promising approach for wireless networks because distributed training can scale across users and reduce latency. Explainability remains essential when large generative models receive decision-making roles in network design, management, and control.

  • B. Distributed GPT: Distributed GPT can provide horizontal scalability by allowing more users to contribute to training.Processing data and training across distributed participants can reduce latency.
  • B. Distributed GPT: Explainability must be studied before large generative models assume authoritative roles in Telecom networks.Operators need to understand AI decisions, while access to the models’ logic can support optimization and trustworthy behavior.
