Hierarchical Online Convex Optimization
Juncheng Wang, Ben Liang, Min Dong +2
We consider online convex optimization (OCO) over a heterogeneous network with communication delay, where multiple workers together with a master execute a sequence of decisions to…
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…
Delay-Tolerant Constrained OCO with Application to Network Resource Allocation
Juncheng Wang, Ben Liang, Min Dong +2
We consider online convex optimization (OCO) with multi-slot feedback delay, where an agent makes a sequence of online decisions to minimize the accumulation of time-varying convex…
Distributed coordinated precoding for MIMO cellular network virtualization
Juncheng Wang, Min Dong, Ben Liang +2
This paper presents a new virtualization method for the downlink of a multi-cell multiple-input multiple-output (MIMO) network, to achieve service isolation among multiple Service…
