不连续接收与电压岛结合的省电方法

摘要

LTE系统支持高速的数据传输。高的数据传输速率需要更复杂的基带调制解调器芯片,这就加快了终端电池的能量的消耗。因此,LTE引入了不连续接收机制(DRX)来延长终端的电池试用时间。结合DRX,本文提出了一个动态的电源管理方案—分层多级电压岛(HMVIP),并建立省电类。结果表明,在单一的LTE终端芯片上,DRX结合HMVIP可以达到更好的省电性能。%　　Long term evolution (LTE) supports large amount of data transmissions. High data rates require more complicated terminal baseband modem chip that drains the user equipment (UE)’s battery power quickly. Hence, LTE proposes an enhanced discontinuous reception (DRX) to prolong the (UE)’s battery lifetime. In this paper, with a combination of DRX, we propose a dynamic power management using hierarchical multi-level voltage island partion (HMVIP) scheme and define some power saving classes. The results show that the DRX with HMVP in a single chip of LTE terminal can achieve a better power saving performance.
