英文摘要： Due to small size, high mobility and flexible deployment of unmanned aerial vehicles (UAVs), constructing small cell networks by deploying UAV basestations is able to make good use of three-dimensional space, provide temporary coverage for connection-constrained area and efficiently improve the service range and quality of ground mobile users, which makes the UAV-assisted small cell networks a helpful supplement for conventional ground cellular networks. However, due to the uniqueness of UAV basestations compared to conventional ground basestations, UAV-assisted small cell networks are still facing many challenges in terms of system design and control. Based on the characteristics of UAV-assisted communications, the project focuses on the issues that UAV-assisted small cell networks are facing and investigates system design and optimal control in the aspects of UAV route planning, wireless power transfer and system resource, aiming at efficient spatial synergy between UAV swarms and ground cellular networks in order to enhance network coverage and improve service quality. In terms of research approaches, the project combines theories and techniques in multiply disciplines such as wireless communications, machine learning, optimal control, which accords with development trend of wireless communication systems, and the results will promisingly provide solid communication support for application scenarios such as unexpected emergency and disaster relief.
