【摘要】：针对双层异构网络架构复杂、干扰严重的问题,利用空间泊松点过程对Macro-Femto双层网络进行了数学建模,推导了室外MUE和室内FUE的下行中断概率,并提出了基于距离和中断概率的家庭基站覆盖及功率控制优化方案。仿真实验表明,所推导的中断概率表达式是正确的,所提出的方案明显减少了宏用户所受的干扰,降低了宏用户的中断概率,有效提升了整个异构网络的性能。
[Abstract]:Aiming at the problem of complex architecture and serious interference of two-layer heterogeneous network, the mathematical model of Macro-Femto bilevel network is established by using spatial Poisson point process, and the downlink interruption probability of outdoor MUE and indoor FUE is deduced.Based on distance and outage probability, an optimized scheme of base station coverage and power control is proposed.Simulation results show that the derived expression of interrupt probability is correct, and the proposed scheme can reduce the interference of macro users, reduce the interruption probability of macro users, and effectively improve the performance of the heterogeneous network.
