Special Issue Information

Dear Colleagues,

AI-Empowered cognitive autonomous networks for low-altitude economy (LAE) represent a paradigm-shifting integration of advanced artificial intelligence, next-generation 6G wireless systems, and intelligent aerial platforms (e.g., UAVs, eVTOLs). This field focuses on developing self-organizing, adaptive, and secure communication and control infrastructures tailored to the dense, dynamic, and three-dimensional operational characteristics of the LAE. By leveraging AI, these networks aim to autonomously manage ultra-reliable, low-latency communications (URLLC), integrated sensing and communication (ISAC), dynamic three-dimensional resource allocation, and mission-critical coordination among massive numbers of heterogeneous aerial nodes. Emerging 6G technologies, such as intelligent reflective surfaces (IRS), terahertz (THz) bands, and native AI architectures, provide the foundational fabric for this integration. However, significant challenges remain in achieving harmonization between the computational intensity of sophisticated AI models and the stringent green, real-time, safety, and security requirements of LAE operations. This Special Issue aims to consolidate cutting-edge research on AI algorithms, 6G network architectures, and cross-layer optimization strategies that enable intelligent, efficient, and trustworthy autonomous networks for the burgeoning low-altitude ecosystem.

Topics of interest include, but are not limited to, the following:

  • AI-native air interface and waveform design for heterogeneous networks;
  • Deep learning for dynamic 3D network topology and resource management;
  • Semantic and goal-oriented communications for multi-modal data streams;
  • Digital twin-enabled optimization for air-ground network orchestration;
  • AI for ultra-reliable low-latency communication (URLLC) in mobile scenarios;
  • Cross-layer optimization using machine learning;
  • AI-enabled energy-efficient green communications;
  • Intelligent reflective surface (IRS) optimization with machine learning;
  • Network automation and self-organizing networks (SON) via AI;
  • Open radio access network (O-RAN) architecture with embedded AI.

The rapid development of the low-altitude economy demands comprehensive electromagnetic spectrum awareness. However, constructing a comprehensive radio environment map (REM) in this scenario is challenging, as spectrum sensing data collected by unmanned aerial vehicles (UAVs) in complex low-altitude environments is typically sparse, fragmented, and non-uniformly distributed across the high-dimensional space of time, frequency, and 3D space. To address these issues, this study proposes a rank-adaptive Bayesian tensor ring completion (Ra-BTRC) framework. The method models the low-altitude electromagnetic environment as a unified five-dimensional (5D) spectrum tensor. It then employs tensor ring (TR) decomposition to capture latent high-order correlations across all dimensions. To overcome the sensitivity of conventional TR methods to predefined ranks, Ra-BTRC introduces sparsity-inducing priors on the TR core factors, enabling variational Bayesian inference to learn observation uncertainty and infer effective TR ranks from sparse measurements without manually fixing the TR rank. Simulations demonstrate that Ra-BTRC significantly outperforms existing TR-based baselines, achieving more than 10 dB MMSE improvement at a 5% sampling rate while accurately recovering local spectrum structures and temporal dynamics. The proposed approach provides a robust and scalable solution for reliable global low-altitude spectrum cognition under stringent sensing budgets. Full article
