Interference is a major impediment in communications via cellular radio networks. Future networks such as Long Term Evolution-Advanced (LTE-A) and 5G networks are no exception and interference issues are liable to degrade network performance drastically. This paper investigates methods for interference mitigation in existing mobile communication standards and proposes a novel technique for reduction of interference. A dynamic transmit power manipulation method is proposed in this work which monitors interference levels in the cellular traffic through Channel Quality Indicator (CQI) reports and maneuvers the device transmit powers according to threshold values based on Signal-to-Interference-and-Noise-Ratio (SINR). A simulation model for the proposed framework is developed to evaluate system performance and results collection.

Mobile users spent most of their time in an indoor environment, therefore it is crucial to develop indoor traffic models for next-generation networks. The significance of this paper is related to the predominant femtocell technology as it is anticipated to be a very crucial part of the modern mobile networks such as 5G and beyond networks. The Femtocell network can satisfy the increased bandwidth demand for video and data traffic with improved network capacity and security. Indoor data traffic exhibits different characteristics that need to be dealt with distinct criteria of the Poisson process and existing classifying techniques. Indoor traffic models, proposed in the literature do not consider long-range dependent characteristics for traffic modeling. Moreover, these traffic models have the ability to capture large flows only. In this paper, we have provided an efficient quality of service-based classifier for downlink transmission in long-term evolution (LTE)-femtocell network. Our proposed algorithm models the indoor traffic by Poisson Lomax Burst Process. Modeled traffic streams, after prioritization, are classified using Markov Decision Process (MDP) classifier. Furthermore, a detailed comparison of our proposed MDP algorithm with the state-of-the-art algorithms in the literature has also been presented. The network performance parameters have been assessed in terms of throughput, delay, and jitter. Simulation results depict a significant improvement in throughput in contrast with Round Robin (RR), which is approximately 8%, 6%, 6%, and 7% for voice, video, BE, and BG services, respectively, while modified least weighted delay first (MLWDF) gives least performance among them. MDP also provides an improvement in delay and average jitter of four different traffic flows and mixed traffic users when compared with RR and MLWDF algorithms.

“…In the closed access mode, no other user can access femtocell services except for a Closed Subscriber Group (CSG) [8]. In the hybrid access mode, the CSG is prioritized over all other users, whereas in open access mode, all users i.e., OSG (Open Subscriber Group) can enjoy the service of the femtocell [9,10]. The access control mode plays an important role in terms of interference, i.e., the Inter-Cell Interference (ICI) is worse in the CSG mode [11].…”

The femtocell has evolved as a great solution for improving coverage and traffic offloading from the current LTE cellular networks, and it accomplishes the dreams of the high data rate for indoor mobile users. However, the exponentially expanding LTE femtocells cause interference in the network, as they share the same licensed spectrum with a macrocell. To tackle this issue, numerous interference mitigation techniques have been proposed in the literature. In this paper, we proposed an Active Power Control (APC) technique, which not only reduces Inter-Cell Interference (ICI) in a Macro User Equipment (MUE), generated from the downlink transmission power of an inadequately deployed femtocell, but also reduces unnecessary power consumption to achieve a green femtocell network. The simulation results show that the proposed APC technique effectively reduces ICI and optimizes the throughput performance of the MUE. Compared with the existing power control techniques, the APC technique provides a balanced trade-off in attaining necessary Quality-of-Service (QoS) of the Femto User Equipment (FUE) and reducing ICI to the victim MUE existing in the close proximity of the femtocell.
