| 中文摘要: |
| 针对智能反射面（intelligent reflecting surface，IRS）联合无人机（unmanned aerial vehicle，UAV）辅助无线通信系统的信息传输速率和能量消耗优化问题，提出了一种创新性的IRS-UAV无线中继传输方案。该方案结合了能量收集和时间切换技术,旨在通过IRS-UAV支持的能量收集来最大化系统的信息传输速率。在该方案中，IRS-UAV先收集基站（base station, BS）发射的能量以维持自身运行,然后反射BS的能量给用户，最后用户利用收集的能量进行信息上传。这种能量收集和中继传输的结合为提高系统性能带来了显著优势。针对该方案中涉及的资源分配、相移矩阵和IRS-UAV位置等高度耦合的非凸优化问题，采用块坐标下降法进行了求解，有效降低了问题的复杂度。 |
| 英文摘要: |
| Aiming at the optimization of information transmission rate and energy consumption of intelligent reflecting surface (IRS) combined unmanned aerial vehicle (UAV)-assisted wireless communication system, an innovative IRS-UAV wireless relay transmission scheme is proposed. The solution combines energy harvesting and time-switching technologies designed to maximize the system’s information transfer rate through energy harvesting supported by the IRS-UAV. In this scheme, IRS-UAV first collects the energy emitted by the base station to maintain its own operation, then reflects the energy of the base station to the user, and finally the user uses the collected energy to upload information. This combination of energy harvesting and relay transmission offers significant advantages in improving system performance. For the highly coupled non-convex optimization problems such as resource allocation, phase shift matrix and IRS-UAV position, the block coordinate descending method is used to solve the problem, which effectively reduces the complexity of the problem. |
