Abstract
Low-Altitude Economic Networking (LAENet) aims to support diverse flying applications below 1,000 meters by deploying various aerial vehicles for flexible and cost-effective aerial networking. However, complex decision-making, resource constraints, and environmental uncertainty pose significant challenges to the development of the LAENet. Reinforcement learning (RL) offers a potential solution in response to these challenges but has limitations in generalization, reward design, and model stability. The emergence of large language models (LLMs) offers new opportunities for RL to mitigate these limitations. We first present a tutorial about integrating LLMs into RL by using the capacities of generation, contextual understanding, and structured reasoning of LLMs. We then propose an LLM-enhanced RL framework for the LAENet in terms of serving the LLM as information processor, reward designer, decision-maker, and generator. Moreover, we conduct a case study by using LLMs to design a reward function to improve the learning performance of RL in the LAENet. Finally, we provide a conclusion and discuss future work.

Abstract
As communication networks expand into non-terrestrial domains, traditional radio frequency (RF) technologies are increasingly becoming bottlenecks in meeting the growing demands for data and connectivity. As a result, future generations of wireless networks are expected to seamlessly integrate multiple bands of spectrum to address the unprecedented demand across underwater, terrestrial, and space environments.
Achieving 3D connectivity requires the convergence of conventional wireless systems with new and emerging technologies tailored to these diverse and challenging applications. Optical wireless communication (OWC) has emerged as a highly promising technology that complements existing RF systems to extend network coverage. In this talk, we will explore how recent advancements in OWC are transforming communication capabilities from underwater, terrestrial and space. The talk will also highlight the key challenges faced in different environments, present emerging solutions, and discuss future perspectives.
