Drone-mounted base-stations (DBSs) are promising complements and substitutes of the terrestrial base-stations. We investigate the problem of Placement and cOmmunications in the DBS-aided heterogeneous network (POD) with tier-1 backhaul using free space optics communications and tier-2 backhaul utilizing in-band full-duplex communications to provide ubiquitous connections and high spectrum efficiency. The POD problem is shown to be NP-hard, and thus we simplify the POD problem by decomposing it into three sub-problems. Finally, we propose an approximation algorithm to solve the POD problem, and demonstrate that the proposed algorithm is superior to two baseline algorithms.
