Abstract: Long Term Evolution LTE in mobile communication is mainly implemented for high speed data transmission, but due to large usage of User Equipment (UE) leads to increase in power consumption. As mobile devices increases rapidly the energy consumption becomes an important issue. Discontinuous Reception (DRX) has been implemented so as to reduce the power consumption of the user equipment, and also transmission of large amount of data. In this paper we propose a relative power saving in order to get a precise result, and also the effectiveness of the power saving is done by combining the short DRX and long DRX cycle. Therefore the parameters values are varied to improve the performance of the DRX mechanism which leads to archive larger power saving in User Equipment

Keywords: Relative power saving, power consumption, DRX, LTE
