Novel Wake-up Signaling for Enhanced Energy-Efficiency of 5G and beyond Mobile Devices

Low-power and low-latency communication features are vital to extend 5G mobile devices functionalities beyond those of the current networks, and to introduce innovative services and applications. On the other hand, limitations of state-of-the-art cellular modules prevent designing and facilitating such features based on current power saving mechanisms alone. In this paper, a new wake-up signaling for 5G control plane is introduced, aiming to reduce energy consumption of cellular module in downlink Performance of the proposed scheme in terms of false alarm and misdetection rates are investigated and evaluated. The obtained numerical results show that such a signaling can reduce power consumption of discontinuous reception (DRX) by up to 30%, at the cost of negligible increase in signaling overhead.
