Mitigating Beam-Split Effects in Near-Field Wideband Communications: A Modular Rotatable Array Approach

In this paper, we propose a new modular rotatable array (MRA) to mitigate the beam-split effect in near-field multi-user communications, by replacing a large number of true-time-delay (TTD) circuits with a small number of mechanically controlled rotating mechanisms to reduce the associated hardware cost and power consu...

Hierarchical Trajectory and Offloading Optimization for Task Delay Minimization in UAV-Assisted MEC

This paper addresses the minimization problem of long-term end-to-end delay within a heterogeneous three-tier unmanned aerial vehicle (UAV)-assisted mobile edge computing network featuring two-hop forwarding. The joint optimization of sensor-node-aggregator association, access/backhaul bandwidth allocation, UAV traject...

Joint Motion Prediction and Adaptive Resource Allocation for Robust ISAC Beam Tracking

Millimeter-wave integrated sensing and communication (ISAC) roadside units need to steer narrow pencil beams toward fast-moving vehicles, and a short sensing outage can trigger a divergent tracking loop: As the tracker drifts, the beam widens, subsequent measurements degrade, and recovery becomes increasingly difficult...

Exploring the Initial Performance of NB-IoT NTN over GEO: Measurement and Analysis

The first comprehensive and in depth measurement for NB-IoT NTN over GEO reveals that as an energy-saving mechanism, Power Saving Mode fundamentally reshapes NB-IoT NTN traffic into a bursty and access-driven communication pattern and thus has a considerable influence on the end-to-end delay and energy consumption.

Fluid Antennas Empowered RIS-Aided Integrated Sensing and Communication Systems

This paper proposes an FA-empowered integrated sensing and communication (ISAC) system in which a reconfigurable intelligent surface (RIS) is employed to mitigate performance degradation in communication and sensing caused by blockages of line-of-sight links.
