Abstract

The use of femtocells is an efficient way to improve coverage and quality of service while on the other side the deployment cost for the service provider is kept in extremely low level. Long Term Evolution Advanced (LTE-A) systems with femtocell overlays aim to provide better indoor voice and data coverage and to increase network capacity. One of the major technical challenges that femtocell networks are facing nowadays, is the cross-tier interference, i.e., the interference between the femto base stations and the macrocell infrastructure. To this direction, we have designed and implemented a framework that simulates femtocell overlays integrated over LTE-A macrocellular systems. This framework focuses on the impact of cross-tier interference and furthermore is able to estimate the throughput at every point of integrated femtocell/macrocell LTE-A networks. In this paper, we present the design and implementation of this simulation framework and we provide significant experimental results obtained with the aid of this system.

具有飞基站覆盖的LTE-A系统仿真框架

使用飞蜂窝是提高覆盖范围和服务质量的有效方法，另一方面，服务提供商的部署成本保持在极低的水平。长期演进高级(LTE-A)系统的目标是提供更好的室内语音和数据覆盖，并增加网络容量。飞蜂窝网络目前面临的主要技术挑战之一是跨层干扰，即飞蜂窝基站与宏蜂窝基础设施之间的干扰。为此，我们设计并实现了一个框架来模拟集成在LTE-A大蜂窝系统上的飞蜂窝覆盖。该框架侧重于跨层干扰的影响，并且能够估计集成飞蜂窝/宏蜂窝LTE-A网络每个点的吞吐量。在本文中，我们给出了该仿真框架的设计和实现，并提供了借助该系统获得的重要实验结果。
