Collaborative Heterogeneous Underlaying Cellular Networks: Fundamental Theories and Key Technologies

从基础理论和关键技术两方面的研究进展与相关成果介绍首届国家重点基础研究发展计划("973"计划)青年科学家专题项目——协同异构蜂窝层叠网络基础理论与关键技术。其中,基础理论包括协同异构蜂窝层叠网络的体系架构、信道建模、网络容量域、连接性等问题;关键技术包括协同异构蜂窝层叠网络的干扰管理、资源分配、空白频谱检测与利用等。研究表明,协同异构蜂窝层叠网络下的D2D(device-to-device)通信由于其具有能够进一步增大频谱利用效率、提升系统容量等优点,将发展成为下一代蜂窝网络支持的关键技术。

The research progress and contributions about the fundamental theories and key technologies of collaborative heterogeneous underlaying cellular networks were introduced.The fundamental theories include the architecture,capacity region,connectivity problem of the collaborative heterogeneous underlaying networks,while the key technologies consist of interference management,wireless resource management,and exploration and utilization of vacant radio-frequency spectrum.The current study shows that D2D communication in collaborative heterogeneous underlaying cellular networks will become the key technology in the next-generation cellular communication systems because it can further improve the spectrum efficiency and system capacity in wireless communication networks.
