    摘要:

    毫微基站(Femtocell)的引入,给无线网络的干扰管理带来新的挑战。在动态部署Femtocell的网络中,每个进入网络的基站选一个载波作为主载波,主载波提供小区的全局覆盖和初始化接入服务。主载波选择的好坏,直接影响小区边缘用户的通信质量。本文提出基于保护邻居基站主载波的家庭基站载波重选算法,基站借助用户测量汇报得到背景干扰信息,重选主载波;本算法着重考虑对邻居基站边缘用户影响,降低小区边缘干扰。仿真结果表明,该算法可以提高系统平均吞吐量和边缘用户的频谱效率。

    Abstract:

    Femtocells posed new challenges in terms of interference management .In dynamic HeNB networks, each user-installed HeNB autonomously selected a component carrier (CC) as primary component carrier (PCC) which provides the cell coverage and initiating work when a HeNB was switched on. The cell-edge performance depended on PCC selection. In this paper, a new cooperative component carrier (re-)selection based on protecting the PCC of surrounding HeNBs scheme was proposed. We argue that carrier reselection based on the Background Interference Matrix (BIM) which is from handover measurements performed by the user equipment (UE) is necessary. We focus on the impact of surrounding neighbor HeNBs to decrease the cell-edge interference。System-level simulation of the proposed schemes improves the total throughout as well as the cell-edge spectrum efficiency.
