Proportional Fairness Optimization with Energy Efficiency guaranteed for FeICIC
首发时间:2015-11-13
Abstract:The paper has studied the user's proportional fairness and system energy efficiency under the joint cell range expansion(CRE) and Further enhanced Inter-Cell Interference Coordination(FeICIC) scheme of two-tier Heterogeneous networks(Het-net). Performances of downlink Het-net including the joint probability density function of signal-interference ratio(SIR), system energy efficiency(EE) and user's proportional fairness(PF) are analyzed. Paper also discusses the influence of CRE bias and power reduction ratio to the EE and PF. In the simulation section, numerical results of EE and PF are obtained. Using these numerical results, we lay a polynomial fitting of EE and PF to do the collaborative optimization. Our analysis shows the optimum parameters setting to obtain the maximum UE's proportional fairness with the energy efficiency guaranteed.

FeICIC场景下保障能效的公平度最优化
摘要:本文主要研究了采用小区偏置和时域干扰协调技术的两层异构网络下的用户公平度及系统能量效率。分析异构网络下行性能,包括下行SIR联合概率分布,系统能量效率以及用户公平度;本文还研究小区偏置值和功率衰减因子对异构网络能效以及公平度的影响。仿真实验中,通过工具计算的精确系统能效以及公平度数值解进行多项式拟合,得到近似表达式,对系统能效以及公平度进行联合优化。并给出在保障系统能效前提下最大化用户公平度的目标下的最优参数配置。
