摘要翻译：
研究了固定速率变功率系统中无人机作为通信中继的最优部署问题。考虑的设置是一组地面发射机(GTs)，希望通过UAVS与一组地面接收机(GRs)通信。每个GT-GR对只通过一架选定的无人机进行通信，没有直接链接。研究了两种不同的无人机选择方案：在集中选择方案中，决策中心根据终端的位置来分配最优无人机。在分布式选择中，GT仅使用其与无人机距离的本地知识来选择其中继无人机。对于这两种选择方案，使用量化理论的工具确定了无人机和燃气轮机功率消耗之间的最优折衷。具体地，在路径损失指数为2$的情况下，分析了一架无人机和多架无人机的两种极值状态。讨论了无人机位置的数值优化问题。模拟结果证实了分析结果。

英文摘要：
  Optimal deployment of unmanned aerial vehicles (UAVs) as communication relays is studied for fixed-rate variable-power systems. The considered setup is a set of ground transmitters (GTs) wishing to communicate with a set of ground receivers (GRs) through the UAVs. Each GT-GR pair communicates through only one selected UAV and have no direct link. Two different UAV selection scenarios are studied: In centralized selection, a decision center assigns an optimal UAV depending on the locations of all terminals. In distributed selection, a GT selects its relaying UAV using only the local knowledge of its distances to the UAVs. For both selection scenarios, the optimal tradeoff between the UAV and GT power consumptions are determined using tools from quantization theory. Specifically, the two extremal regimes of one UAV and very large number of UAVs are analyzed for a path loss exponent of $2$. Numerical optimization of UAV locations are also discussed. Simulations are provided to confirm the analytical findings.
