“…Although this scheme can reduce the time of beamforming, it has poor flexibility without considering the changes of the surrounding environment. In [25], [26], a dynamic beam-aware DRX scheme is proposed, which could be applied along with dynamic mmWave beam configuration for better energy efficiency. In [27], a fast beam tracking DRX scheme is proposed in the UAV scenario with D2D structure, focusing on analyzing system performance from sleep rate and average packet delay.…”

M2M (Machine to Machine) technology has a broad application prospect in 5G network, but one of the bottlenecks is the energy consumption of intelligent devices powered by battery. In this paper, we study the energy saving strategy in 5G millimeter wave system. Firstly, a Discontinuous Reception scheme based on Beam Measurement (BM-DRX) is proposed to avoid the unnecessary beamforming. Secondly, by modifying the frame structure and optimizing the beamforming, the time of beamforming is further shortened and the power consumption is also saved. Finally, based on the ETSI (European Telecommunications Standards Institute) data model, the beam misalignment events are regarded as Poisson distribution, and the semi-Markov process is used to analyze the BM-DRX. Simulation results show that the proposed scheme can not only meets the delay performance, but also saves the energy consumption of the system. INDEX TERMS 5G, M2M, BM-DRX, energy saving, delay I. INTRODUCTIONIn the Fifth Generation (5G) communication networks, some strategies are used to satisfy the demands of growing data capacity, data rate and provide the best quality of service requirements. Firstly, in order to improve the data bandwidth and connection efficiency, achieve better download and upload speed and less delay, bands are specified in two Frequency Ranges (FR) in 3GPP Release 15. FR1 ranges from 450 MHz to 6000 MHz, known as cmWave. FR2 ranges from 24250 MHz to 52600 MHz, which are commonly referred to as mmWave. Moreover, some technology such as beamforming are use in 5G network. References [1], [2] show that millimeter wave spectrum can support high-speed data rate by using beamforming technology with multi-antenna arrays. Efficient beamforming is helpful to improve spectrum efficiency, reduce system interference and enhance wireless communication security. At the same time, with the rapid development of electronics and computer, the intelligent devices can fulfill the requirement of higher bandwidth service [3]. M2M (Machine to Machine) communication is widely used in 5G Internet of Things (IoT) [4], including the fields of industrial vehicle network, automation, smart grid, telemedicine, etc. With the exponential growth of the number of M2M intelligent devices, the data flow is expanding rapidly. The increasing of M2M devices will not only affect Access Networks (ANs) but also Core Networks (CNs). Because most of the devices are powered by battery, such as intelligent wearable devices, UAVs (unmanned aerial vehicles), intelligent electric meters, the power saving of intelligent device is a crucial issue for the 5G M2M network. Thus, increasing energy efficiency in mobile networks will reduce the costs of capital and operational expenditures. It makes energy efficiency extremely important. There are many energy saving technologies for 5G wireless networks. Some recent researches on green 5G technology and communication energy harvest are reviewed in reference [5]. Some new technologies are also discussed related to energy saving technology includi...

The Dual connectivity (DC) technology is a robust solution for Internet service providers (ISP) to evolve their legacy infrastructures with less cost to speed up the progress of fifth-generation (5G) services coverage. DC enables the traditional network to connect to multiple New Radio (NR) Node B (gNBs). A well-known scheme is the non-standalone (NSA) NR. In this case, the user equipment (UEs) could access the network via both the evolved Node B (eNB) and the gNB. However, some research has indicated that the UEs in such a configuration suffer from power consumption problems. UEs are typically configured with discontinuous reception (DRX) mechanism to save power. However, most current systems do not investigate and optimize the DRX parameters. To the authors' best knowledge, this work is the first to combine DRX with traffic steering for the UEs in the NSA NR system. A traffic steering algorithm is proposed to improve the coordination between the eNB and the gNB. We used a semi-Markov chain model to analyze power consumption and average delay. Compared with standard DRX operated in LTE, NR, and DC, we verified that the proposed model achieves power-saving gains without incurring an additional delay. The results indicated that the UE could save considerable power with an optimized system configuration.
