Device Activity Detection for Massive Grant-Free Access Under Frequency-Selective Rayleigh Fading
Yuhang Jia, Ying Cui, Wuyang Jiang
Device activity detection and channel estimation for massive grant-free access under frequency-selective fading have unfortunately been an outstanding problem. This paper aims to a…
Statistical Device Activity Detection for OFDM-based Massive Grant-Free Access
Yuhang Jia, Ying Cui, Wuyang Jiang
Existing works on grant-free access, proposed to support massive machine-type communication (mMTC) for the Internet of things (IoT), mainly concentrate on narrow band systems under…
An Optimization Framework for Federated Edge Learning
Yangchen Li, Ying Cui, Vincent Lau
The optimal design of federated learning (FL) algorithms for solving general machine learning (ML) problems in practical edge computing systems with quantized message passing remai…
Energy-efficient Cooperative Offloading for Edge Computing-enabled Vehicular Networks
Hewon Cho, Ying Cui, Jemin Lee
Edge computing technology has great potential to improve various computation-intensive applications in vehicular networks by providing sufficient computation resources for vehicles…
Robust Optimization of Instantaneous Beamforming and Quasi-static Phase Shifts in an IRS-assisted Multi-Cell Network
Yuhang Jia, Ying Cui, Wuyang Jiang
The impacts of channel estimation errors, inter-cell interference, phase adjustment cost, and computation cost on an intelligent reflecting surface (IRS)-assisted system are severe…
Optimization-based Block Coordinate Gradient Coding
Qi Wang, Ying Cui, Chenglin Li +2
Existing gradient coding schemes introduce identical redundancy across the coordinates of gradients and hence cannot fully utilize the computation results from partial stragglers.…
