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

A low-power and low-latency communication system is vital to extend 5G mobile devices functionality, and to introduce innovative services and applications; on the contrary, limitations of state-of-the-art cellular subsystems prevent designing such a system 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 subsystem in downlink. Performance of the proposed scheme in terms of false alarm and misdetection 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 increments in signaling overhead.
