A communication network may include a satellite configured to provide a plurality of satellite cells within a satellite coverage area, and one or more unmanned aerial vehicles (UAVs) configured to fly within the satellite coverage area. Each UAV is configured to fly over one of the satellite cells. A resource allocation system may be configured to dynamically allocate at least a portion of a frequency spectrum between the satellite and the UAV(s). Each UAV provides a plurality of UAV cells within a satellite cell in response to the resource allocation system allocating the frequency spectrum (or portion thereof) to the UAV(s).
