异构网络中动态TDD技术的应用可以有效提高系统吞吐量,改善系统性能。由于受到信令控制等问题的限制,授权频段上往往只是实现传统的7种固定子帧配比之间的动态切换。而非授权频段作为工作在授权频段上LTE系统的一个补充,不用考虑信令控制等问题,可以实现更加灵活的完全动态子帧配置。提出了两种非授权频段上的动态子帧配置算法,并与传统的静态子帧配置进行比较,通过LAA系统级仿真平台验证动态子帧配置算法对系统性能的影响。仿真表明,提出的两种动态子帧配置算法可以有效提升资源利用率,提高系统整体吞吐量。
The use of dynamic TDD technology in heterogeneous network can effectively increase the system throughput and improve the performance of the system.Due to the limitation of signaling control and other issues
there is usually a dynamic switching between the traditional seven fixed sub-frame ratios in the licensed bands.But as a complement to the LTE system worked in the licensed bands
the unlicensed bands can achieve a more flexible and complete dynamic sub-frame configuration without considering signaling control and other issues.Two new dynamic sub-frame configuration algorithms in unlicensed bands were proposed and compared with traditional static sub-frame configuration
then the impact of dynamic sub-frame allocation algorithms on system performance was verified by LAA system level simulation platform.The results show that the proposed dynamic sub-frame configuration strategies can effectively improve the resource utilization and the overall system throughput.
