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.
