3-D Positioning and Resource Allocation for Multi-UAV Base Stations Under Blockage-Aware Channel Model

no code implementations23 Nov 2022 Pengfei Yi, Lipeng Zhu, Zhenyu Xiao, Rui Zhang, Zhu Han, Xiang-Gen Xia

Based on the proposed channel model, we formulate the joint optimization problem of UAV three-dimensional (3-D) positioning and resource allocation, by power allocation, user association, and subcarrier allocation, to maximize the minimum achievable rate among users.

Joint 3-D Positioning and Power Allocation for UAV Relay Aided by Geographic Information

no code implementations12 Oct 2021 Pengfei Yi, Liang Zhu, Lipeng Zhu, Zhenyu Xiao, Zhu Han, Xiang-Gen Xia

To improve communication capacity, we first model the blockage effect caused by buildings according to the three-dimensional (3-D) geographic information.

A Survey on Millimeter-Wave Beamforming Enabled UAV Communications and Networking

no code implementations19 Apr 2021 Zhenyu Xiao, Lipeng Zhu, Yanming Liu, Pengfei Yi, Rui Zhang, Xiang-Gen Xia, Robert Schober

The utilization of the millimeter-wave (mmWave) frequency bands is a promising direction for UAV communications, where large antenna arrays can be packed in a small area on the UAV to perform three-dimensional (3D) beamforming.
