Special Issue on Recent Advances in Extremely-High-Frequency Wireless Networks
Submission Date: 2025-11-15

The rapid advancement of next-generation applications has driven an unprecedented demand for ultra-high data rates, ultra-low latency, and high-precision sensing. To meet these requirements, the wireless research community is actively exploring extremely-high-frequency (EHF) communication and sensing technologies, leveraging the ultra-wide bandwidth of millimeter-wave (mmWave) and terahertz (THz) signals. Despite their potential, EHF signals suffer from severe path loss and molecular absorption, which restrict their communication range. Additionally, they are highly susceptible to blockages, necessitating advanced beam management techniques to ensure reliable connectivity. Hardware limitations, including the efficiency constraints of power amplifiers (PAs) and non-ideal behaviors of analog-to-digital/digital-to-analog converters (ADCs/DACs), pose further challenges. Last but not least, dense EHF small-cell networks can overwhelm centralized controllers, thus requiring new, distributed, and hierarchical network architectures to handle complexity. The tight coupling between physical-layer conditions (e.g., link blockage) and network-layer decisions also demands new cross-layer designs.

Fortunately, recent advancements in EHF wireless technologies have addressed many of these issues. Researchers have developed low-complexity precoding methods and new beam alignment techniques to enhance beam management performance. EHF wireless networks have also spurred innovations in high-precision imaging, localization, and environmental mapping, aligning with the vision of ubiquitous sensing-communication integration in 6G networks. New reconfigurable antenna systems have emerged and offered more cost-effective and flexible beamforming solutions compared to conventional large-scale antenna arrays. On the hardware front, progress in PA, ADC/DAC, and frequency multiplier designs has facilitated long-range, high-speed data transmission and high-resolution real-time video streaming. Standardization efforts have also gained momentum, with IEEE 802.15.3d supporting 100 Gbps links in the 252–325 GHz range, and ITU-R Working Party 5D exploring IMT above 100 GHz. From the network-layer perspective, advanced routing protocols that account for directional links and link intermittency has been proposed to avoid deafness and reduce alignment delay in EHF networks. Machine learning models (e.g., reinforcement learning, GNNs, LLMs) predict link quality, node mobility, and blockage to optimize routing in EHF wireless networks.

Given these recent developments, this special issue aims to focus on the algorithm design, hardware innovations, protocol development, and standardization efforts for EHF wireless networks. Prospective authors are invited to submit original manuscripts on topics including but not limited to:

Special Issue on Semantic Communications with Intellicise (Intelligent and Concise) Networking
Submission Date: 2025-12-01

In recent years, intellicise (intelligent and concise) networks have played a crucial role by transforming conventional networking paradigms, which emphasize the use of native intelligence and endogenous simplified architecture to achieve a state of self-evolution, self-optimization, and self-balance. In this context, unlike traditional data-centric networking that focuses on raw bit-level transmission, semantic communications with intellicise networking extract, transmit, and process high-level contextual representations. Therefore, semantic communications with intellicise networking enhances contextual adaptability and network scalability in dynamic and large-scale environments.

Despite its potential, semantic communications with intellicise networking face several critical challenges. To meet the fluctuating demands of modern networks, network management must not only be adaptive but also context-aware, dynamically adjusting resource distribution and traffic flows based on semantic importance to minimize latency and enhance efficiency. Furthermore, ensuring privacy-preserving communication, robust security mechanisms, and effective trust management is crucial in heterogeneous, large-scale, and dynamic network environments, where only contextually relevant information should be transmitted. In addition, the interplay between semantic communication and intellicise network structures remains an open research challenge. The evolution of semantic-aware traffic can impact network topology, routing protocols, and congestion control, necessitating new methodologies for network optimization. Latency-aware compression techniques are essential for understanding the large-scale deployment of semantic communication. Moreover, defining new performance indicators, such as semantic fidelity, effective bandwidth, and information transfer efficiency, will allow for better quantification of communication efficiency in networked environments. This special issue seeks to advance these areas by exploring novel architectures, methodologies, and applications.

Special Issue on Advanced Application of Graph Representation Learning in Communication Networks
Submission Date: 2026-01-01

The rapid advancement of emerging communication technologies, such as flexible antennas and integrated sensing and communication, has driven the evolution of communication networks toward both high-dimensional resource utilization and multifunctional integration. This evolution poses challenges in efficiently designing communication networks to satisfy the quality-of-service and time-sensitive requirements of mobile applications in dynamic environments. In view of the notable successes of deep learning (DL) in numerous application fields, applying DL to enhance network intelligence has become an inevitable trend. DL can be integrated into communication networks across almost all layers to enhance resource utilization efficiency and network security. Furthermore, DL serves as a key enabler that gives rise to innovative wireless applications, such as semantic communications.

The task-specific characteristic of DL necessitates the customization of learning strategies and neural networks for communication networks. Communication networks comprise core components that naturally form a graph structure, such as wireless topologies and routing patterns. Therefore, graph representation learning (GRL) has emerged as a powerful DL tool to re-design communication networks. Particularly, graph neural networks (GNNs) have been increasingly recognized as one fundamental model for graph-structured communication networks. GNNs not only augment the extraction of features over the network topology but also facilitate scalable and distributed computation. GRL/GNNs can be integrated with existing wireless DL approaches as a network feature extractor. For instance, the superiority of GNNs over other neural networks has been widely demonstrated in addressing wireless optimization problems following the “learning-to-optimize” paradigm to enable real-time and scalable inference of (near-)optimal resource allocation. GRL/GNNs shift traditional iterative optimization methods to data-driven and model-based strategies, introducing unprecedented flexibility in addressing complex problems. Exploring the advanced application of GRL/GNNs in upcoming 6G can support a variety of fundamental and practical communication designs and optimization schemes, including but not limited to

    Real-time Optimization: GRL/GNNs can automatically learn to approximate the optimal mapping from network topologies to targeted resource allocation strategies, routing results, etc., thereby enabling real-time computation.
    Scalable and Distributed Implementation: GRL/GNNs are scalable to elements in communication networks, enabling signal processing in ultra-dense and dynamic wireless environments. The scalability also facilitates distributed implementation by integrating the signaling exchange of wireless networks with the message-passing mechanism of GNNs.
    Unified Solution Framework: Learning on a graph modeling a specific network topology can extract critical topological features. The features can be harnessed to tackle diverse problems via a unified framework. Fine-tuning pre-trained GNNs via transfer learning can further enhance the solving performance.
    Complex Problem Solver: Data-driven DL offers a transformative paradigm to tackle complex communication problems through GRL/GNNs. This novel paradigm for constructing problem solvers balances the trade-off between performance and efficiency of heuristic algorithms.
    Wireless Intelligence Module: By casting GNNs as a network topology-aware feature extraction module, they can be seamlessly integrated into other wireless DL architectures (such as wireless generative artificial intelligence (GAI) and wireless large language models (LLMs)) to jointly support wireless intelligence.

While GRL/GNNs can realize intelligent signal processing, there remains a pressing need for advanced model architectures and effective mechanisms to enhance the learning performance and tackle the challenges such as guaranteeing feasible solutions, capturing heterogeneous relationships for diverse wireless services, achieving robust information transmission, enabling efficient deployment strategies, etc. Besides, the lack of standardized datasets, task definitions, and unified evaluation metrics poses challenges to the reproducibility of experimental procedures in DL-enabled signal processing. Therefore, an in-depth exploration of the connection between the DL approach and the communication tasks is urgently required for the application of GRL/GNNs in communication networks.

The integration of DL and communication networks demonstrates a cutting-edge field with revolutionary potential in future mobile communication systems. This special issue is dedicated to exploring the breakthroughs in the advanced applications of GRL in communication networks from both the theoretical and practical perspectives, in order to provide a more comprehensive understanding of the philosophy of DL-enabled communication networks.
