LTE Small Cell Baseband Core & Protocol Stack Technologies Supporting SON and Interference Coordination ‒ TDD and FDD, 5MHz, 10MHz, 15MHz and 20MHz ‒ Synchronization including GPS, IEEE 1588 V2, and network listener ‒ Self-configuration and optimization including automatic neighbor relation, PCI selection and conflict resolution, and inter-cell power control ‒ Interference co-ordination including ICIC and eICIC SON enabled LTE Small Cell Reference Design including ‒ L1 link level and system level simulation platforms. ‒ Enhanced baseband (L1) and SON-enabled protocol stack modules (RRM and MAC in L2/L3) supporting SON and interference coordination. ‒ Test infrastructure to verify and validate 3GPP requirements. 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

本项目将研发用於LTE小型基站的SON和干扰协调技术以满足在4G异构网部署小基站的需求。 异构网是指小基站覆盖範围和宏基站重叠。 此类网络部署可以让小基站有效地分流宏基站的业务从而达到提高系统容量目的。我们的技术将加强现有的LTE小基站基带核并通过多小区协调，自配置，自优化来管理小区之间的干扰。 项目的开发成果包括 （1）增强的基带核和协议栈技术用来实现SON和干扰协调，（2）LTE SON小基站参考设计包括L1链路和系统仿真平台，支持SON和干扰协调的基带(L1) 和协议栈模块 L2/L3中的无线资源管理和媒体接取及一套完整测试平台来验證小基站。 ASTRI目前为领先的LTE小基站技术提供者。 本项目将我们在基带的领先地位扩展到网络规划和部署，能够大幅度提高本地与大中国区的晶片供应商，设备製造商和运营商的在LTE市场上的竞争力。 因此已经有多家公司对此项目产生兴趣。 其中福建叁元达和飞思卡尔已确定将对本项目提供产业贡献。而其他尚有广州海华电子，世纪互联， 和记电讯亦积极与项目团队洽谈合作及转移项目产出和衍生技术。
