【摘要】：針對雙層異構(gòu)網(wǎng)絡(luò)架構(gòu)復(fù)雜、干擾嚴(yán)重的問題,利用空間泊松點(diǎn)過程對Macro-Femto雙層網(wǎng)絡(luò)進(jìn)行了數(shù)學(xué)建模,推導(dǎo)了室外MUE和室內(nèi)FUE的下行中斷概率,并提出了基于距離和中斷概率的家庭基站覆蓋及功率控制優(yōu)化方案。仿真實(shí)驗(yàn)表明,所推導(dǎo)的中斷概率表達(dá)式是正確的,所提出的方案明顯減少了宏用戶所受的干擾,降低了宏用戶的中斷概率,有效提升了整個(gè)異構(gòu)網(wǎng)絡(luò)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.
