Selection of Relays in Multi-Pair D2D Communication with Multicast
Original language description
This paper investigates Device-to-Device (D2D) communication with multiple user equipments (UEs) acting as sources intending to transmit information to their respective destinations via intermediate relay represented by, e.g., UEs or unamnned aerial vehicles (UAVs). We propose a novel solution for the selection of the relays serving multiple D2D pairs. We allow multiple D2D pairs to use the same relay while the D2D pairs reuse the same channel to increase spectrum usage. To mitigate interference, we exploit a multicast transmission with precoding to distinguish the transmission for each D2D pair and to increase the system capacity. The simulations demonstrate that our proposed scheme provides a significant gain (up to two times) in terms of capacity compared to the competitive schemes.
