Joint Power Allocation and User Association Optimization for IRS-Assisted mmWave Systems
Dan Zhao, Hancheng Lu, Yazheng Wang +2
Intelligent reflect surface (IRS) is a potential technology to build programmable wireless environment in future communication systems. In this paper, we consider an IRS-assisted m…
Reliability Enhancement for VR Delivery in Mobile-Edge Empowered Dual-Connectivity Sub-6 GHz and mmWave HetNets
Zhuojia Gu, Hancheng Lu, Peilin Hong +1
The reliability of current virtual reality (VR) delivery is low due to the limited resources on VR head-mounted displays (HMDs) and the transmission rate bottleneck of sub-6 GHz ne…
Association and Caching in Relay-Assisted mmWave Networks: From A Stochastic Geometry Perspective
Zhuojia Gu, Hancheng Lu, Ming Zhang +2
Limited backhaul bandwidth and blockage effects are two main factors limiting the practical deployment of millimeter wave (mmWave) networks. To tackle these issues, we study the fe…
Energy Efficiency Optimization in IRS-Enhanced mmWave Systems with Lens Antenna Array
Yazheng Wang, Hancheng Lu, Dan Zhao +1
In millimeter wave (mmWave) systems, the advanced lens antenna array can effectively reduce the radio frequency chains cost. However, the mmWave signal is still vulnerable to block…
Joint Passive Beamforming and User Association Optimization for IRS-assisted mmWave Systems
Dan Zhao, Hancheng Lu, Yazheng Wang +1
In this paper, we investigate an intelligent reflect surface (IRS) assisted multi-user millimeter wave (mmWave) downlink communication system, exploiting IRS to alleviate the block…
