Discrete Coupling and Localized Motion for Pinching-Antenna Systems (PASS)

The practical implementation of pinching-antenna systems (PASS) is challenging due to hardware limitations in large-scale antenna movement and continuous radiation power adjustment. This paper proposes a practical PASS-enabled downlink multi-user multiple-input multiple-output communication framework that enables discr...

Latency-Optimized IoT Communications Through Information-Centric Caching: A Survey

This paper aims to survey the integration of Information-Centric Networking (ICN) with the Internet of Things (IoT), considering various aspects, including the role of Named Data Networking (NDN) caching schemes in mitigating latency in IoT use cases. Current IP-based protocols may not adequately meet IoT system requir...

Covert Air–Ground Federated Learning With Pruning: Enabling by STAR-RIS

Federated learning (FL) can safeguard the data privacy for air-ground networks, while simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) can help further enhance its channel quality. However, the model exchanges in FL may be detected by wardens, and air-ground links increase this t...

Movable Antenna-Enabled Covert Communications in ISAC Networks

Movable antennas (MAs) can reshape the propagation environment by continuously adjusting their spatial positions compared with fixed-position antennas (FPAs). Leveraging this advantage, we develop an alternating optimization framework for covert integrated sensing and communication (ISAC) systems. This framework jointl...

QoE-Aware Network Slicing and Resource Allocation for Stable Mobile Online Learning

Mobile online learning is challenged by the inherent conflict between dynamically evolving pedagogical demands and rigid resource provisioning infrastructures. Conventional quality of service (QoS)-driven resource allocation paradigms suffer from two critical limitations: 1) limited responsiveness to temporal-spatial f...

Multiple Access Design and Resource Allocation in Pinching-Antenna Systems

Multiple access (MA) design is investigated to facilitate pinching-antenna systems (PASS)-based multi-user communications. By exploiting the newly introduced waveguide domain and existing frequency domain, two MA schemes are explored, namely pure waveguide division multiple access (WDMA) and hybrid WDMA. For each MA sc...

Beamforming-Aided Wireless Multimodal Federated Learning: Dynamic Pruning and Joint Optimization

Wireless multimodal federated learning (MFL) is promising for privacy-preserving edge intelligence, but its practical deployment is challenged by modality heterogeneity, client resource heterogeneity, and the high communication and computation cost of multimodal models. This paper proposes a beamforming-aided wireless...

Task-Oriented Framework for Communication-Efficient Federated Learning: From Isolated Optimization to Holistic Synergy

This article presents an autonomous driving case study with two complementary experiments: a task-oriented client scheduling strategy that improves object detection accuracy under the same communication time budget, and a joint quantization-bandwidth optimization that further reduces total training time under dynamic n...

Wireless Fronthauls in Full-Duplex Cell-Free Massive MIMO Systems

In this paper, we investigate a full-duplex (FD) cell-free massive multiple-input multiple-output (CF mMIMO) architecture with millimeter wave (mmWave) fronthaul, where uplink (UL) and downlink (DL) payload data and control signaling must be simultaneously supported. We first revisit the fronthaul requirements of repre...
