Abstract
Since mobile traffic has been growing recently, the deployment of indoor small cells has become an attractive solution to enhance coverage. However, the increasing density of cells makes inter-cell interference more considerable. In this paper, we propose a max-throughput Interference Avoidance (MTIA) centralized algorithm to improve the system's throughput. Based on signaling and reports, a central controller connected to each base station can properly turn off base stations that may induce a relatively strong interference, and thus increase SINR. We implemented the MTIA algorithm in an LTE TDD network simulation and showed that MTIA effectively reduces inter-cell interference and improves the system's throughput. © 2017 The Korean Institute of Communications Information Sciences
