Collaborative Edge AI Inference over Cloud-RAN

no code implementations9 Apr 2024 Pengfei Zhang, Dingzhu Wen, Guangxu Zhu, Qimei Chen, Kaifeng Han, Yuanming Shi

To realize efficient uplink feature aggregation, we allow each RRH receives local feature vectors from all devices over the same resource blocks simultaneously by leveraging an over-the-air computation (AirComp) technique.

Distributed Auto-Learning GNN for Multi-Cell Cluster-Free NOMA Communications

no code implementations28 Apr 2022 Xiaoxia Xu, Yuanwei Liu, Qimei Chen, Xidong Mu, Zhiguo Ding

A multi-cell cluster-free NOMA framework is proposed, where both intra-cell and inter-cell interference are jointly mitigated via flexible cluster-free successive interference cancellation (SIC) and coordinated beamforming design.

Millimeter-Wave NR-U and WiGig Coexistence: Joint User Grouping, Beam Coordination and Power Control

no code implementations11 Aug 2021 Xiaoxia Xu, Qimei Chen, Hao Jiang, Jun Huang

Our aim for the proposed coexistence network is to maximize the spectral efficiency while ensuring the strict NR-U delay requirement and the WiGig transmission performance in real time environments.

Graph-Embedded Multi-Agent Learning for Smart Reconfigurable THz MIMO-NOMA Networks

no code implementations15 Jul 2021 Xiaoxia Xu, Qimei Chen, Xidong Mu, Yuanwei Liu, Hao Jiang

With the accelerated development of immersive applications and the explosive increment of internet-of-things (IoT) terminals, 6G would introduce terahertz (THz) massive multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) technologies to meet the ultra-high-speed transmission and massive connectivity requirements.
