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…
Task Offloading and Resource Allocation with Multiple CAPs and Selfish Users
Eric Jiang, Meng-Hsi Chen, Ben Liang +1
In this work, we consider a multi-user mobile edge computing system with multiple computing access points (CAPs). Each mobile user has multiple dependent tasks that must be process…
Periodic Updates for Constrained OCO with Application to Large-Scale Multi-Antenna Systems
Juncheng Wang, Min Dong, Ben Liang +1
In many dynamic systems, decisions on system operation are updated over time, and the decision maker requires an online learning approach to optimize its strategy in response to th…
