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.
