Multi-UAV Interference Coordination via Joint Trajectory and Power Control
Chao Shen, Tsung-Hui Chang, Jie Gong +2
In this paper, we consider an unmanned aerial vehicle-enabled interference channel (UAV-IC), where each of the UAVs communicates with its associated ground terminals (GTs) at t…
Joint Beamforming and Power Allocation in Downlink NOMA Multiuser MIMO Networks
Xiaofang Sun, Nan Yang, Shihao Yan +4
In this paper, a novel joint design of beamforming and power allocation is proposed for a multi-cell multiuser multiple-input multiple-output (MIMO) non-orthogonal multiple access…
Transmission Energy Minimization for Heterogeneous Low-Latency NOMA Downlink
Yanqing Xu, Chao Shen, Tsung-Hui Chang +3
This paper investigates the transmission energy minimization problem for the two-user downlink with strictly heterogeneous latency constraints. To cope with the latency constraints…
Max-Min Fairness User Scheduling and Power Allocation in Full-Duplex OFDMA Systems
Xiaozhou Zhang, Tsung-Hui Chang, Ya-Feng Liu +2
In a full-duplex (FD) multi-user network, the system performance is not only limited by the self-interference but also by the co-channel interference due to the simultaneous uplink…
Flight Time Minimization of UAV for Data Collection over Wireless Sensor Networks
Jie Gong, Tsung-Hui Chang, Chao Shen +1
In this paper, we consider a scenario where an unmanned aerial vehicle (UAV) collects data from a set of sensors on a straight line. The UAV can either cruise or hover while commun…
