Abstract

Telecommunication has seen distinct upgrade since the innovation of wireless communication. The latest addition is LTE-Advanced. LTE-Advanced requires implementation of femtocell. Spontaneous femtocell deployment introduces cross-tier and co-tier interference as well as further cost for uniform installation. In this paper, we describe outlines to solve the encountered problems and discuss the feasibility of the proposed outlines. The outlines contain efficient reuse of macrocell RF channels to indoor femtocells by dynamic spectrum allocation. The autonomous, Cognitive Radio-enabled technology is the premise of femtocells driven by LTE-Advanced. Cognitive Radio ensures offloading from macrocells by craftily imparting over accessible range. Application of on Access Control List concept further enhances femtocell capability. Additionally, hardware and software deployment costs are matched with macrocell. The reservations aim to satisfy the criterion identified as Quality of Service. The choice of femtocell over WLAN is favored by considering authorization and co-existential constraints.

4G网络中femtocell的干扰管理与成本分析视角

自无线通信技术出现以来，电信行业出现了明显的升级。最新加入的是LTE-Advanced。LTE-Advanced需要实现femtocell。自发的移动基站部署引入了跨层和共层干扰，以及统一安装的进一步成本。在本文中，我们描述了大纲，以解决遇到的问题，并讨论了所提出的大纲的可行性。该方案通过动态频谱分配，有效地将宏基站射频信道复用到室内飞基站。自主的认知无线电支持技术是LTE-Advanced驱动的飞蜂窝的前提。认知无线电通过巧妙地在可到达的范围内传输信号，确保从宏细胞中卸载。接入控制列表概念的应用进一步提高了飞基站的性能。此外，硬件和软件部署成本与macrocell相匹配。保留的目的是满足确定为服务质量的标准。考虑到授权和共存约束，选择无线基站优于无线局域网。
