Fractional Frequency Reuse Based Adaptive Power Control Scheme for Interference Mitigation in LTE-Advanced Cellular Network with Device-to-Device Communication

摘要

In this paper, we propose a frequency planning and transmission (Tx) power management scheme, called Fractional Frequency Reuse based Adaptive Power Control (FFR. APC) Scheme for orthogonal frequency division multiple access (OFDMA) and time division duplex (TDD) based on 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 different frequency bands and optimal Tx power chosen as D2D links' locations in inner and outer zones in different periods to reduce interference substantially. Simulations show the proposed scheme outperforms D2D networks with soft frequency reuse (SFR) and Fractional Frequency Reuse (FFR) schemes in terms of the system throughput and outage probability for mUEs and D2DRs.
