TDD-LTE与LTE FDD混合组网研究

Research on the Hybrid Network of TDD-LTE and LTE FDD

当前TDD-LTE网络已基本实现市区、县城及农村区域的全覆盖,在5G大规模承载之前,4G网络的主要矛盾表现为在网络的承载能力与日益增长的高速率大容量需求方面。TDD-LTE网络的承载能力面临较大压力,基于此开展LTE FDD网络扩容则成为4G网络的重要补充。本文重点研究了LTE FDD与TDD-LTE两张网络的部署定位以及策略,并结合现阶段的市场整体发展情况,提出LT E FDD及TDD-LTE网络的建设方案以及建设策略,为TDD-LTE以及LTE FDD网络的融合组网提供相关参考。

The current TDD-LTE network has basically achieved full coverage in urban,county and rural areas.The main contradiction of 4G networks is the carrying capacity of the network and the increasing demand for high-speed and large-capacity.The bearer capability of the TDD-LTE network is under great pressure.Based on this,the expansion of the LTE FDD network becomes an important supplement to the 4G network.This paper focuses on the deployment positioning and strategy of LTE FDD and TDD-LTE networks.Combined with the overall development of the market at this stage,this paper proposes the construction plan and construction strategy of LTE FDD and TDD-LTE networks.
