Abstract :
We propose the ADRX (adaptive discontinuous reception) mechanism with the EPI (extended paging indicator) for power saving in the UMTS (Universal Mobile Telecommunications System). In the proposed mechanism, DRX period for each UE (user equipment) is individually and adaptively controlled by the EPI which is decided by node B considering the current traffic situation of each UE. Simulation results show significant improvement of power saving performance by the proposed mechanism as compared to the conventional fixed DRX
