M2M Energy Saving Strategy in 5G Millimeter Wave System

Machine to Machine technology has a broad application prospect in the 5G network, but there is a bottleneck in the energy consumption of intelligent devices powered by the battery. In this paper, we study the energy-saving strategy in the 5G millimeter-wave system. Firstly, a Discontinuous Reception scheme based on Beam Measurement (BM-DRX) is proposed to avoid unnecessary beamforming. Secondly, we modified the frame structure and optimized the beamforming to short the beamforming time and save the power consumption. Finally, based on the European Telecommunications Standards Institute data model, we used the semi-Markov process to analyze the BM-DRX by considering the beam misalignment events as a Poisson distribution. Simulation results show that the proposed scheme can not only meet the delay performance, but also save the energy consumption of the system.
