Bounded Deep Unfolding for Joint Beamforming and Scheduling in Multi-Cell MIMO Networks
Jiansheng Li, Shuqi Chai, Fan Xu +4
This paper investigates the joint resource block group (RBG) scheduling and beamforming optimization problem for weighted sum-rate (WSR) maximization in multi-cell multiuser multip…
Two-Tier Precoding for FDD Multi-cell Massive MIMO Time-Varying Interference Networks (Full Version)
Junting Chen, Vincent K. N. Lau
Massive MIMO is a promising technology in future wireless communication networks. However, it raises a lot of implementation challenges, for example, the huge pilot symbols and fee…
Hierarchical Radio Resource Optimization for Heterogeneous Networks with Enhanced Inter-cell Interference Coordination (eICIC)
An Liu, Vincent K. N. Lau, Liangzhong Ruan +2
Interference is a major performance bottleneck in Heterogeneous Network (HetNet) due to its multi-tier topological structure. We propose almost blank resource block (ABRB) for inte…
Convergence Analysis of Mixed Timescale Cross-Layer Stochastic Optimization
Junting Chen, Vincent K. N. Lau
This paper considers a cross-layer optimization problem driven by multi-timescale stochastic exogenous processes in wireless communication networks. Due to the hierarchical informa…
Large Deviation Delay Analysis of Queue-Aware Multi-user MIMO Systems with Multi-timescale Mobile-Driven Feedback
Junting Chen, Vincent K. N. Lau
Multi-user multi-input-multi-output (MU-MIMO) systems transmit data to multiple users simultaneously using the spatial degrees of freedom with user feedback channel state informati…
Delay Analysis of Max-Weight Queue Algorithm for Time-varying Wireless Adhoc Networks - Control Theoretical Approach
Junting Chen, Vincent K. N. Lau
Max weighted queue (MWQ) control policy is a widely used cross-layer control policy that achieves queue stability and a reasonable delay performance. In most of the existing litera…
