摘要(中) 近年來,高品質的行動通訊需求大量增加,而在未來的行動通訊網路中,為了要滿足大量且各式各樣的需求,會有許多不同後端網路支援與不同發射功率的基地台共存,因此異質網路在近年來被廣泛的討論,其中毫微型基地台網路(femtocell network)被許多研究人員注意並且認為其適用於下一代行動通訊,原因是因為它體型輕巧,能安置在辦公室與住宅,因此可解決行動通訊覆蓋率不佳及室內傳輸量不足等棘手問題,以提高無線資源重複使用的效率。而毫微型基地台在3G末已被提出討論,但一直遲遲無法發展的原因即是干擾協調的問題,干擾主要分為來自大型基地台的干擾與毫微型基地台彼此之間互相干擾等兩種情況。這些干擾會影響到使用者聯網品質,造成網路延遲、斷線以及訊號消失等問題,因此我們必須最優先去討論的即是細胞之間的干擾協調(inter-cell interference coordination,ICIC)。
摘要(英) In recent years, demand for high-quality mobile communications is significant increasing. In the future, in order to meet the large and wide variety of needs, there will be many different back-end network and different power of base stations coexist. Therefore, heterogeneous network has been widely discussed in recent years. Femtocell network are considered suitable for next-generation mobile communication because it is small size that can place in the office and house and it can solve inadequate coverage of mobile communication problem. Femtocell network

has been discussed at the end of 3G, but the reason that it could not have been developed is the problem of interference coordination. Interference is divided into two categories. The first interference is from large base stations and the second interference is femtocell base stations with each other. These interference will affect network quality of users, network delays, disconnection and signal problems, so we must discuss interference coordination (inter-cell interference coordination, ICIC) first.
