Marketing acitivities including: ‒ Discussion with the existing partner (Sunnada) on the SON small cell requirements to secure their commercialization. ‒ Demonstrating SON small cell technology in the industry tradeshows. ‒ Discussion with the infrastructure vendors (e.g. Freescale's customers, Gemtek, Airspan, and so on) for the potential technology licensing. ‒ Discussing and securing the further collaborations with the existing partner (Sunnada) . ‒ Demonstrating the SON small cell technology with the operators and HK public agents (MTR/ HKSTP/HKPF). ‒ Discussion of the potential business opportunities for the SON small cell applications in the private and public networks. Note: FDD: Frequency Division Duplex TDD: Time Division Duplex PCI: Physical Cell Identity GPS: Global Positioning System ICIC: Inter-Cell Interference Coordination eICIC: Enhanced Inter-Cell Interference Coordination SON: Self Organizing Networks RRM: Radio Resource Management MAC: Media Access Control L1: Layer 1 L2/L3: Layer 2, Layer 3 3GPP: 3rd Generation Partnership Project

本項目將研發用於LTE小型基站的SON和干擾協調技術以滿足在4G異構網部署小基站的需求。 異構網是指小基站覆蓋範圍和宏基站重疊。 此類網絡部署可以讓小基站有效地分流宏基站的業務從而達到提高系統容量目的。我們的技術將加強現有的LTE小基站基帶核並通過多小區協調，自配置，自優化來管理小區之間的干擾。 項目的開發成果包括 （1）增強的基帶核和協議棧技術用來實現SON和干擾協調，（2）LTE SON小基站參考設計包括L1鏈路和系統仿真平台，支持SON和干擾協調的基帶(L1) 和協議棧模塊 L2/L3中的無線資源管理和媒體接取及一套完整測試平台來驗證小基站。 ASTRI目前為領先的LTE小基站技術提供者。 本項目將我們在基帶的領先地位擴展到網絡規劃和部署，能夠大幅度提高本地與大中國區的晶片供應商，設備製造商和運營商的在LTE市場上的競爭力。 因此已經有多家公司對此項目產生興趣。 其中福建三元達和飛思卡爾已確定將對本項目提供產業貢獻。而其他尚有廣州海華電子，世紀互聯， 和記電訊亦積極與項目團隊洽談合作及轉移項目產出和衍生技術。
