The invention discloses an unmanned aerial vehicle auxiliary data collection system and method, and belongs to the field of wireless communication. The system comprises a plurality of sensor nodes which are uniformly organized into a plurality of clusters; in each cluster, a plurality of sensor nodes are paired into a group and share a frequency resource block; the unmanned aerial vehicle is used for collecting data of ground sensor nodes and eliminating multiple access interference in each group by adopting a serial interference elimination technology so as to decode signals of each sensor node; wherein the minimum throughput of the sensor nodes is maximized by considering optimization of pairing-decoding of the sensor nodes, transmission power and trajectory points of the unmanned aerial vehicle. According to the method, the pairing scheme, the decoding sequence, the transmitting power and the unmanned aerial vehicle track points of the sensor nodes are jointly optimized, so that the minimum throughput of the sensor nodes is improved to the maximum extent, and a flexible, efficient and reliable data collection solution is provided for the wireless sensor network.
