Abstract :
The high-speed communication environment and high-performance mobile devices have leveraged each other. Long Term Evolution (LTE) supports high bandwidth and low latency for data transfer. However, high bandwidth transfer will spend the mobile device´s battery power rapidly. To extend the user equipment (UE)´s battery life time, LTE adopts enhanced Discontinuous Reception (DRX) mechanism. Even though LTE supports DRX framework to reduce power consumption, DRX not only depends on base-station but also needs sufficient idle time to operate efficiently. In this paper, we propose a novel adaptive power management technique of LTE model which reduces the active (i.e. non-DRX period) power consumption. Our experimental results shows that a communication modem with the proposed method improves energy saving by 40.72% compared to previous modem.
