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.
