DRL‐Based Joint Clustering and Trajectory Optimization for UAV‐Assisted Emergency Networks
6G is expected to see unprecedented data traffic surges. UAV‐assisted MEC aids emergency communications but faces challenges from dynamic user mobility and heterogeneous tasks. To address these, the proposed KM‐PPO integrates interference‐aware k‐means clustering (for user aggregation and initial UAV deployment) and PPO (for stable policy updates and ...

Transformer‐Based Fusion for Joint Routing and Resource Allocation in the Internet of Things
In this work, we investigate decentralized joint routing and resource allocation for high‐quality path establishment at the network layer of the Internet of Things (IoT). We propose a novel optimization framework based on Transformer‐based Deep Reinforcement Learning (DRL), which enables the fusion of observations and actions along communication paths.

Energy‐Efficient Element Selection in RIS‐Assisted Backscatter Communication Systems
This paper investigates energy‐efficient reconfigurable intelligent surface (RIS) assisted ambient backscatter communication systems with energy‐harvesting tags. A low‐complexity RIS element selection strategy is developed to satisfy both energy‐harvesting and signal‐to‐interference‐plus‐noise ratio constraints while minimizing overall power ...

This letter presents a high‐Q tunable waveguide (WG) filter with constant absolute bandwidth (CABW). Modified cavity perturbation theory (CPT) is adopted for the first time to analyze the tuning mechanism. the proposed tunable WG filter maintains much better S‐parameter performance compared with a majority of reported high‐Q tunable filters, thus, it ...
