В настоящей статье рассматриваются несколько ключевых подходов к решению задачи снижения межсотовой интерференции в мобильных сетях LTE, обусловленной отсутствием повторного использования частот. На основе разработанной авторами имитационной модели был осуществлён сравнительный анализ существующих решений с точки зрения достигаемой пропускной способности и вероятности блокировки каналов трафика PUSCH и PDSCH. Результаты моделирования наглядно демонстрируют неэффективность использования временного разделения ресурсов на краях сот между абонентами, обслуживаемыми разными станциями, в рамках любых процедур координации межсотовой интерференции.

This article covers some key approaches to problem solving of reducing inter-cell interference in mobile LTE networks, caused by lack of frequency reuse. On the basis of the authors' simulation model, a comparative analysis of the existing solutions in terms of attainable bandwidth and the probability of blocking traffic channels PUSCH and PDSCH was implemented. Simulation results demonstrate the inefficient use of time division of resources at the edges of cells between subscribers served by different stations as part of any inter-cell interference coordination procedures.
