Joint Downlink-Uplink Beamforming for Wireless Multi-Antenna Federated Learning

Chong Zhang, Min Dong, Ben Liang +2

We study joint downlink-uplink beamforming design for wireless federated learning (FL) with a multi-antenna base station. Considering analog transmission over noisy channels and up…

Random Caching Design for Multi-User Multi-Antenna HetNets with Interference Nulling

Tianming Feng, Xuemai Gu, Ben Liang

The strong interference suffered by users can be a severe problem in cache-enabled networks (CENs) due to the content-centric user association mechanism. To tackle this issue, mult…

Fast First-Order Algorithm for Large-Scale Max-Min Fair Multi-Group Multicast Beamforming

Chong Zhang, Min Dong, Ben Liang

We propose a first-order fast algorithm for the weighted max-min fair (MMF) multi-group multicast beamforming problem in large-scale systems. Utilizing the optimal multicast beamfo…

Resource Allocation for Massive MIMO HetNets with Quantize-Forward Relaying

Ahmad Abu Al Haija, Min Dong, Ben Liang +1

We investigate how massive MIMO impacts the uplink transmission design in a heterogeneous network (HetNet) where multiple users communicate with a macro-cell base station (MCBS) wi…

Online Multi-Cell Coordinated MIMO Wireless Network Virtualization with Imperfect CSI

Juncheng Wang, Ben Liang, Min Dong +1

We consider online coordinated precoding design for downlink wireless network virtualization (WNV) in a multi-cell multiple-input multiple-output (MIMO) network with imperfect chan…
