摘要
长期演进(LTE)有FDD和TDD两种制式,FDD覆盖范围广但频谱资源占用较大,而TDD容量覆盖大,频谱资源相对丰富,为了满足用户高速率上网的卓越体验,TD-LTE和LTE FDD两网融合成为了关键问题。通过对LTE FDD和TD-LTE关键技术、帧结构、物理架构以及设备终端等方面的分析,充分说明了TD-LTE与LTE FDD融合组网的可行性。
The Long Term Evolution （LTE） have two standards of FDD and TDD.The FDD has large coverage area,but it has high resource occupation.The TDD has larger capacity and abundant spectrum resource.In order to meet user’ s superior experience of high-speed Internet,the fusion networking of TD-LTE and LTE FDD has become a key problem.In this paper,the feasibility of fusion networking of TD LTE and LTE FDD is proved by analyzing such aspects as LTE FDD and TD-LTE key technology,frame structure, physical architecture and terminal equipment.
