Resource allocation and power control scheme for interference avoidance in LTE-Advanced device-to-device communication

In this paper, we propose a resource allocation and Tx power control scheme, called resource allocation and power control (RAPC), in LTE Advanced device-to-device (D2D) network. In the proposed scheme, the macro base station (mBS) and D2D senders (D2DSs) service macro user equipments (mUEs) and D2D receivers (D2DRs) use the different frequency bands and Tx power chosen as D2D links' locations in inner and outer zones to reduce interference substantially. Simulations show the proposed scheme outperforms D2D networks with soft frequency reuse (SFR) systems in terms of the signal to interference and noise ratio (SINR) and system throughput for mUEs and D2DRs.
