Since wireless mobile communication has been used, the number of wireless communication devices is increasing. In addition, mobile communication terminals are demanding a large amount of communication resources in response to an increasingly high communication speed requirement. In this situation, users are currently experiencing a serious lack of communication resources. In order to solve this problem, various researches have been carried out for efficient use of communication resources, especially frequency resources. One of them is successive interference cancellation (SIC), which is the core technology of non-orthogonal multiple access. In this paper, we will apply the SIC technique to mobile base station, especially UAV which is used as base station. UAV is also often used as an alternative to communications in many extreme situations, such as disaster situations. In extreme situations, the supply of communication resources may not be smooth and it is difficult to guarantee QoS of communication due to various constraints. Therefore, to improve the efficiency of frequency bandwidth, which is one of communication resources, we apply SIC technology to UAV characteristics and propose scheduling algorithm. In order to simultaneously consider the channel capacity and fairness in the whole system, a proportional fairness algorithm is applied to the user pairing algorithm of SIC technology. The performance of this algorithm is compared with the previously proposed algorithms and simulation calculated. ⓒ 2017 DGIST
