User Equipment Energy Efficiency Versus LTE Network Performance
The purpose of this paper is to analyze the tradeoff conditions between battery saving opportunities at the user terminal and Long Term Evolution network performance. To achieve the goal Voice over IP with discontinuous reception and a vast amount of different settings, including on duration, inactivity and discontinuous reception cycle timers, have been studied. An adaptive discontinuous reception with synchronizing the on duration time with the Voice over IP packet arrival has been proposed to minimize the delays caused by discontinuous reception. In addition, a channel quality indicator preamble time has been introduced to enable channel quality indicator update prior the on duration period.
