TLDR
Heterogeneous scheduling schemes are carried out at Femto-Marco base stations, which enhanced the performance of the system without any overheads and the proposed scheme is compared with the existing scheduling algorithm in terms of throughput, spectral efficiency and delay.Abstract:
Deployment of Femtocell within Marco Cell will improve the network coverage area of not only outdoor users but also those inside building premises. Such deployment willbenefit the network operator as it resolves the deployment of additional base station. Only concern is to allocate the resource in interference limited scenarios in Femto-Marco. The works reported in literature use identical scheduling scheme for both Marco and Femto base stations. In this paper, heterogeneous scheduling schemes are carried out at these stations, which enhanced the performance of the system without any overheads. The proposed scheme is compared with the existing scheduling algorithm in terms of throughput, spectral efficiency and delay. Algorithm is 38.63 %better compared to literature value in term of spectral efficiency.read more

QoS-Aware and Energy-Efficient Resource Management in OFDMA Femtocells
TL;DR: A novel distributed femtocell power adaptation algorithm is devised, which converges to the Nash equilibrium of a corresponding power adaptation game and reduces energy consumption for femtocells while still maintaining individual cell throughput.

Fractional Frequency Reuse Aided Twin-Layer Femtocell Networks: Analysis, Design and Optimization
Fan Jin,Rong Zhang,Lajos Hanzo +2 more
TL;DR: It is found that the advantage of FFR eroded in dense femtocell-scenarios and the optimized network tends to become a Unity Frequency Reuse (UFR) aided system, so the proposed spectrum swapping access (SSA) strategy is more robust to the detrimental impact of femtocells.

An LTE-femtocell dynamic system level simulator
TL;DR: A dynamic system level simulator for LTE networks was developed for investigating the interference behaviour of femtocells placed within macrocells, which simulates a multi-cell, multi-user and multi-carrier system in the downlink for Single-Input, Single-Output and Multiple- input, Multiple-Output antenna configurations.

Interference avoidance via resource scheduling in TDD underlay femtocells
TL;DR: Results show that self-organizing femtocell operating in an uncoordinated way achieves a good tradeoff of performance when a limited feedback from femto users is exchanged.
