摘要(中) 在這科技日益增長的年代，人們對於無線網路的需求越來越龐大，無線網路供應商正面臨資料量大量增長的問題以及用戶連線品質等相關問題。一般而言，大部分使用無線裝置的使用者都是位於室內，例如.家裡或是辦公室。但由於建築物的阻擋以及穿透牆壁所造成的訊號衰減，經常是造成室內覆蓋率不佳的原因 。所以我們可以自行在家中部署家用型基地台來增加室內的覆蓋率，但在同一個區域內同時存在著大型基地台以及數個家用型基地台，將會造成同頻之間的干擾，導致系統產出量降低。
本文將使用最小權重隊列機制，一個利用協調的方式去減少干擾，並且結合LTE-A的載波聚合機制，載波聚合不僅可以在家用型基地台間做載波單元的協調來避免干擾的產生，也可以利用聚合載波來提升基地台整體的頻寬(最高可至100MHz)。 最後，在模擬的結果圖中，可看出使用JWSQ干擾協調演算法的系統產出量明顯的改善。
摘要(英) Wireless services providers are experiencing tremendous growth of mobile data traffic, due to generated indoors, mostly located in home and office. But, indoor coverage has always been a problem due to the large penetration loss when the radio signal travels through walls of the buildings from the base station.
So, we can deploy the home eNodeBs (HeNBs) to increase the coverge of base station in the house. HeNBs are deployed over the existing macrocell network and share the same frequency spectrum with macrocells. Due to spectrum scarcity, femtocells and macrocells have to reuse the total allocated frequency band partially or totally which leads to co-channel interference.
In this thesis, we propose the JWSQ scheme, a coordination interference scheme to deal with femtocells in LTE-Advenced networks with carrier aggregation (CA). Carrier Aggregation not only can use the coordination among carriers to reduce interference , but also to support very high data rate transmissions over wide frequency bandwidths(e.g., up to 100 MHz). Finally, we can see that simulation results demonstrate the effectiveness of the JWSQ based interference coordination scheme in terms of throughput.
