This paper investigates joint trajectory planning and computation offloading in multi-UAV assisted mobile edge computing (MEC) networks within complex 3D urban environments. Existing deep multi-agent reinforcement learning (MARL) methods often oversimplify obstacles as geometric no-fly zones, ignoring fine-grained chan...

Concurrent long-range (LoRa) transmissions over the same time-frequency and spreading factor (SF) resources generally result in packet collisions, as the gateway cannot distinguish the overlapping signals from different end devices (EDs). This paper advocates a new fluid antenna multiple access (FAMA) framework for LoR...

Cell-free massive multiple-input multiple-output (CF-mMIMO) is a promising paradigm for future wireless networks, providing user-centric services and cooperative coverage. By using unmanned aerial vehicles (UAVs) as aerial access points, CF-mMIMO networks can exploit UAV mobility to enhance three-dimensional (3D) cover...
