Resource allocation and power control scheme for interference avoidance in an LTE-advanced cellular networks with device-to-device communication

Abstract

In this paper, we propose a resource allocation and Tx power control scheme, called resource allocation and power control (RAPC) in an LTE-Advanced device-to-device (D2D) network. In the proposed scheme, the macro base station (mBS) and D2D senders (D2DSs) service macro user equipment (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. We analyze and compare the proposed scheme and random resource allocation (RRA) scheme with fractional frequency reuse (FFR) systems in terms of the system throughput for DL and outage probability according to the number of D2D user's (D2DR) traffic density. Simulation results show that the RAPC scheme has better performance than the random resource allocation (RRA) scheme performance in terms of the system throughput and outage probability for mUEs and D2DRs.
