TD-LTE系统DRX机制的分析与设计

摘要

In order to reduce the power consumption of the user equipment, and further support the transmission of a wide range of business and the large amount of data. The Long Term Evolution (TD -LTE)system adopts discontinuous reception (DRX) mechanisms. This article through various timer operation which analyze in detail the basic principles of DRX mechanism and design a specific realization scheme for adaptive DRX mechanism. The simulation results show that this mechanism in the reduction of power consumption is greatly improved, at the same time, it ensure the good experience of the user.%为了降低移动终端的功率消耗,并且进一步支持多种业务和大量数据的传输,在长期演进(TD-LTE)系统中引入了非连续接收省电机制(DRX).通过各种定时器的操作详尽分析了DRX机制的基本原理,设计出一种自适应DRX机制的具体实现方案.仿真结果表明,此机制在减少功率消耗方面有很大的改进,同时保证用户的良好体验.
