What is it about?
In this paper, we consider a set of UAVs are deployed in the air to work as relays to aid the ground device-to-device (D2D) pairs.

Why is it important?
For the reason that the communication resource on one relay is limited and the positions of the relays are different, network performance is impacted directly by relay assignment. Considering that there is no center controller in this relay network, centralized relay assignment approaches can’t be used. Thus, we propose a novel decentralized relay selection approach based on relay exchange, aiming to maximize the total capacity of the network. With the proposed approach, the total capacities of the networks are strictly non-decreasing with the increase of the iteration steps. Numerical results show that the proposed approach have attractive properties.
Perspectives
With the advantage of high flexibility, unmanned aerial vehicle (UAV) can be deployed in a high height to provide high probability of line-of-sight (LoS) transmission for the ground units. Thus, UAV can bring much gain for communication systems.
