Co-Tier Interference Reduction with Intelligent Scheduling in between LTE Femtocells

In wireless networks, there is an ever-increasing demand for higher system throughput along with growing expectation for all users to be available to multimedia and Internet services. This is especially difficult to maintain at the cell-edge. To deal with the increasing demand of high speed data streaming and good quality voice traffic from mobile users at home, Femtocell Networks are deployed in homes that enables an indoor mobile user to achieve high speed downloading from the internet and make good quality voice calls. Femtocell networks suffer from the problem of interference. In this paper, a contribution to the existing research on the avoidance of interference in Femtocell networks is presented. The proposed methodology designs a resource allocation and reuse mechanism combined with allocating different resource blocks and interference-aware reuse. The presented results show that the proposed methodology can efficiently mitigate the Co-tier as well as Cross-tier interference in LTE based cellular networks and outperform the other mechanism.

A Review on Co-Tier Interference Reduction Techniques In Between LTE Femtocells

ABSTRACT: Nowadays LTE (Long Term Evaluation) network becomes more popular and main issue regarding LTE network is indoor coverage. In LTE spectrum is limited so to increase spectral efficiency most of the operator deploy single frequency network but this also increase level of interference. Femtocell deployment inside Macrocell network can reduce indoor coverage issue but unplanned placing of Femtocells as per user requirements may create interference between Femtocells which is called as "Co-tier interference" which may have an impact on the overall performance of Femtocells. Avoiding such interference is very important for Femtocells to work properly. Hence this research survey seeks to analyze various techniques used for Co-tier interference reduction in LTE Femtocell networks are discussed in this review paper
