摘　　要：随着无线业务的快速发展,网络负荷将会越来越高,特别是LTE商用以来,数据业务的迅速增长将很快对网络承载带来巨大压力。基于ONE LTE融合网络理念,广州联通在大学城进行了FDD/TDD融合组网的应用和探索。利用FDD BBU框硬件共享方式,实现FDD/TDD快速融合建网。通过交叉覆盖、异频组网以及负荷分担等创新策略的实施,FDD/TDD融合网络不仅实现了容量大幅提升,而且使得用户感知得到明显改善。研究结果表明,FDD/TDD融合组网可有效利用中国联通现有频谱资源,并能满足中国联通未来网络发展需要。With the rapid development of wireless services,the load of network has been getting heavier and heavier,especially since the start of the LTE network construction in China,the rapid growth of data services will soon carry enormous pressure on the network. Based on the concept of ONE LTE which is a integrated network with FDD and TDD,Guangzhou Unicom has took up the application and research for the integrated network with FDD and TDD in Guangzhou University city. Through the implementation of the network strategy,such as cross coverage,inter frequency networking and load sharing,both the capacity of network and the terminal user perception was significantly improved. The results show that the integrated network with FDD and TDD can effectively utilize the existing spectrum resources and meet the needs of the future network development of China Unicom.
