Partial Co-channel based Overlap Resource Power Control for Interference Mitigation in an LTE-Advanced Network with Device-to-Device Communication

摘要

In Long Term Evolution-Advanced (LTE-A), many techniques for improving the throughput of the system have been suggested. One among these techniques is the deployment of device-to-device (D2D) communication as an underlay to the International Mobile Telecommunications-Advanced (IMT-A) cellular network. However, deploying D2D technology in overlay macro cellular network may generate high interference to macro users (mUEs) as the D2D devices shares the same spectrum resource with mUEs. In this paper, we propose a partial co-channel based overlap resource power control (PC.OVER) scheme by mitigation of co-channel interference between mUE and D2D receiver (D2DR). In the proposed scheme, when more than one D2DR competes for the same resource with mUE, the power for those D2DRs which compete for the resource with mUE is reduced to low power. The simulation results show that the proposed scheme outperforms D2D with partial co-channel scheme in terms of the system throughput and outage probability for mUEs and D2DRs.
