Green Emergency Communications in RIS- and MA-Assisted Multi-UAV SAGINs: A Partially Observable Reinforcement Learning Approach
Liangshun Wu, Wen Chen, Shunqing Zhang +2
In post-disaster space-air-ground integrated networks (SAGINs), terrestrial infrastructure is often impaired, and unmanned aerial vehicles (UAVs) must rapidly restore connectivity…
A Model-Data Dual-Driven Resource Allocation Scheme for IREE Oriented 6G Networks
Tao Yu, Simin Wang, Shunqing Zhang +6
The rapid and substantial fluctuations in wireless network capacity and traffic demand, driven by the emergence of 6G technologies, have exacerbated the issue of traffic-capacity m…
Learning to Beamform for Cooperative Localization and Communication: A Link Heterogeneous GNN-Based Approach
Lixiang Lian, Chuanqi Bai, Yihan Xu +3
Integrated sensing and communication (ISAC) has emerged as a key enabler for next-generation wireless networks, supporting advanced applications such as high-precision localization…
IREE Oriented Active RIS-Assisted Green communication System with Outdated CSI
Kai Cao, Tao Yu, Jihong Li +5
The rapid evolution of communication technologies has spurred a growing demand for energy-efficient network architectures and performance metrics. Active Reconfigurable Intelligent…
Intelligent Reflecting Surface Aided MIMO Networks: Distributed or Centralized Architecture?
Guangji Chen, Qingqing Wu, Wen Chen +4
We investigate the capacity of a broadcast channel with a multi-antenna base station (BS) sending independent messages to multiple users, aided by IRSs with N elements. In particul…
