In unmanned aerial vehicle (UAV)‐enabled wireless communications, the total UAV energy is limited, which includes propulsion energy and communication‐related energy. Integrating UAVs and non‐orthogonal multiple access (NOMA) into cellular networks is considered to be a promising technique to significantly enhance the performance of terrestrial users in the next‐generation wireless system and beyond. The two communication concepts, UAV and NOMA, can be naturally linked together as a new spectrum and energy‐efficient wireless transmission technique, which is the focus of this chapter. Two user selection strategies are proposed based on the serving purposes to perform NOMA. They are the user‐centric strategy is a promising solution for providing access services after disasters in remote areas; and the UAV‐centric strategy can be perfectly deployed in dense networks, i.e., concerts or football matches, to provide supplementary access services for offloading actions, where terrestrial users are located in a regular disk.
