Energy-Efficient RF Chain Activation for Uplink mmWave Cell-Free Massive MIMO Systems: A Minimum-Cost Maximum-Flow Approach
Bo Yu, Abdol Hamid Aghvami, Mohammad Shikh-Bahaei
With the incessant demand for green and sustainable communications, energy efficiency (EE) has become a cornerstone of sixth-generation (6G) network design, especially for cell-fre…
Alternating Optimization for Joint Resource Allocation in Full-Duplex Multi-Sector Fluid Antenna-Enabled Near-Field Systems
Jingxuan Zhou, Yinchao Yang, Zhaohui Yang +2
This paper proposes a full duplex fluid antenna near field system (FD-FANS) with a multi-sector antenna array that jointly exploits resource allocation, antenna mobility, and group…
TOIB: Task-Oriented Orthogonalised Information Bottleneck for Distributed Semantic Communication
Jiaxiang Wang, Zhaohui Yang, Yahao Ding +2
Task-oriented semantic communication emerges as a crucial paradigm for next-generation wireless networks, aiming to efficiently transmit task-relevant information while reducing in…
Joint Device Pairing and Bandwidth Allocation Optimisation for Semantic Feature Multiple Access Networks
Jiaxiang Wang, Zhaohui Yang, Mingzhe Chen +1
This paper presents a Semantic Feature Multiple Access (SFMA) framework for multi-user semantic communication in downlink wireless systems. By extending SwinJSCC to a two-user supe…
Semantic Feature Multiple Access Empowered Integrated Learning and Communication Networks
Jiaxiang Wang, Zhouxiang Zhao, Yahao Ding +4
