  • 摘要: 利用非授權(quán)頻段頻譜資源提升網(wǎng)絡(luò)容量需要有效地解決LTE(Long Term Evaluation)與WiFi的共存問題。最近,學(xué)術(shù)界和工業(yè)界相繼提出了授權(quán)頻段輔助接入機(jī)制和雙模微基站技術(shù)提升蜂窩通信系統(tǒng)容量。考慮雙模微基站與WiFi接入點(diǎn)覆蓋范圍存在部分重疊場(chǎng)景,該文提出一種新的雙模微基站非授權(quán)信道接入機(jī)制及聯(lián)合授權(quán)非授權(quán)的優(yōu)化頻譜資源分配方案。仿真結(jié)果表明,雙模微基站和WiFi接入點(diǎn)互不可見時(shí),新方案相比于現(xiàn)有方案由于考慮了空間復(fù)用具有更好的系統(tǒng)性能;雙模微基站和WiFi接入點(diǎn)互相可見時(shí),新方案與現(xiàn)有方案性能一致,即兩者分時(shí)獨(dú)立占用非授權(quán)頻段頻譜資源。
