摘要/Abstract

摘要： 在无人机毫米波多用户通信网络中，基于波束空间多输入多输出系统提出了一种利用无人机移动特性的波束选择方法.首先，以减少用户间的能量泄漏为目标设计了无人机基站的最优部署位置；然后，为避免不同用户选择同一波束造成射频链路浪费的情况，提出了一种通过用户接收能量衡量的波束重新选择准则.仿真结果表明，相比传统的波束选择方法，所提方法可以实现接近最优的系统和速率性能以及更高的能量效率.

Abstract: A millimeter-wave unmanned aerial vehicle (UAV) cellular multiuser network is investigated based on beamspace multiple-input and multiple-out put. A beam selection scheme assisted by UAV mobility is proposed. At first, an optimal deployment position of UAV base station is identified with the aim of reducing power leakage problem among users. Afterwards, a simple power focused beam selection criterion called beam reselection is introduced to avoid the problem that the same beam is selected by different users, which will cause the waste of radio-frequency chains. Numerical simulations results show that the proposed scheme achieve near optimal achievable sum rate performance and higher power efficiency compared with conventional beam selection scheme.

Key words: millimeter-wave communication, unmanned aerial vehicle, beam selection, beamspace multiple-input and multiple-out put
