Joint Trajectory and Resource Allocation Design for UAV Communication Systems
Ruide Li, Zhiqiang Wei, Lei Yang +4
In this paper, we investigate resource allocation design for unmanned aerial vehicle (UAV)-enabled communication systems, where a UAV is dispatched to provide communications to mul…
Multi-Beam NOMA for Hybrid mmWave Systems
Zhiqiang Wei, Lou Zhao, Jiajia Guo +2
In this paper, we propose a multi-beam non-orthogonal multiple access (NOMA) scheme for hybrid millimeter wave (mmWave) systems and study its resource allocation. A beam splitting…
Multi-cell Hybrid Millimeter Wave Systems: Pilot Contamination and Interference Mitigation
Lou Zhao, Zhiqiang Wei, Derrick Wing Kwan Ng +2
In this paper, we investigate the system performance of a multi-cell multi-user (MU) hybrid millimeter wave (mmWave) communications in a multiple-input multiple-output (MIMO) netwo…
A Multi-Beam NOMA Framework for Hybrid mmWave Systems
Zhiqiang Wei, Lou Zhao, Jiajia Guo +2
In this paper, we propose a multi-beam non-orthogonal multiple access (NOMA) framework for hybrid millimeter wave (mmWave) systems. The proposed framework enables the use of a limi…
Mitigating Pilot Contamination in Multi-cell Hybrid Millimeter Wave Systems
Lou Zhao, Zhiqiang Wei, Derrick Wing Kwan Ng +2
In this paper, we investigate the system performance of a multi-cell multi-user (MU) hybrid millimeter wave (mmWave) multiple-input multiple-output (MIMO) network adopting the chan…
Joint Pilot and Payload Power Control for Uplink MIMO-NOMA with MRC-SIC Receivers
Zhiqiang Wei, Derrick Wing Kwan Ng, Jinhong Yuan
This letter proposes a joint pilot and payload power allocation (JPA) scheme to mitigate the error propagation problem for uplink multiple-input multiple-output non-orthogonal mult…
