摘　　要：分层网络和载波聚合作为LTE系统的2种主要组网方式,对未来网络发展趋势起着重要作用。在介绍单一频点分层网络和多频点分层网络的网络架构、应用场景、技术优势以及存在问题的基础上,详细介绍了与分层网络技术紧密结合的载波聚合技术,重点分析了载波聚合与分层网络相结合后的融合组网发展趋势,详细给出了近期目标、中期目标和远期目标作为运营商网络建设的重要参考依据。Multi-Layer network and carrier aggregaton, as two major forms of network deployment, play important role in the development of LTE. Based on introduction of structure, application scenario, technology adventage and existing problem of single frequency and multi-frequency multi-layer network, this paper introduces in detail the carrier aggregation technology. The development trend of fusion uetworking is analyzed in detail based on conlbination of multi-layer network and carrier aggregation. Finally, the near term, medium term anti long term goals of network deployment are presented as a key reference for the telecommunication operator.
