作者： Zhiyu Huang shuzhen Liu Zhichao sheng Hongwen Yu Antonino Masaracchia Key Laboratory of specialty Fiber Optics and Optical Access Networks Shanghai University school of Electronics Electrical Engineering and Computer Science Queen's University Belfast

In this paper, we study an unmanned aerial vehicle(UAV)-assisted communication system, where the UAV is dispatched to implement simultaneous transmission and reception(sTR) in the existence of multiple malicious jammers. Two schemes are investigated, namely frequency band-division-duplex(FDD) and time-fraction(TF). Based on the FDD scheme, the UAV can transmit information by using the portion of the bandwidth and receive information within the remaining portion of the bandwidth simultaneously. To perform the sTR within the whole bandwidth, the TF-based scheme is considered by using a fraction of a time slot for the downlink, while the remaining fraction of the time slot is allocated for the uplink. We aim to maximize the worst-case throughput by optimizing the UAV three-dimensional(3D) trajectory and resource allocation for each scheme. The optimization problem is non-convex and thus computationally intractable. To handle the nonlinear problem, we use the block coordinate decomposition method to disaggregate the optimization problem into four subproblems and adopt the successive convex approximation technique to tackle non-convex problems. The simulation results demonstrate the performance of the TF-based scheme over the benchmark schemes.
