“…In the last years, a sleep mode was widely applied to enable the User Equipment (UE) to turns off its Radio Frequency (RF) part when no traffic arrival intimation from the Base Station (BS) so that UE battery lifetime was extended [3,4,12,15]. In [3], the Discontinuous Reception (DRX) sleep mode was introduced for the Long Term Evolution (LTE) networks.…”

Energy consumption is one of the most important challenges in Millimeter Wave (mmWave) 5G wireless communications since higher data rate and lower latency are required. Thus, User Equipment (UE) battery suffers from its energy absorption. To investigate a green communication, Discontinuous Reception (DRX) mode is introduced when no traffic arrival from the Base Station (BS) to extend UE battery lifetime but delay is increased. This paper introduces an advanced DRX, which can achieve extended UE battery lifetime with a reasonable reduced delay due to a proposed sub-frame size. Generally, traffic which arrives may be data packet or paging message. This paper evaluates two proposed system models based on traffic which arrives during wake up periods of the UE. The first system model is called Signaling Based DRX and the second system model is called Enhanced Paging Monitoring (EPM). The both system models utilize two different indicators; they are Power Saving Indicator (PSI) and Paging Early Indicator (PEI), respectively. These indicators enhance power saving and delay compared to that of the traditional approach. The evaluation of the both system models performance is by measuring the power saving factor and the average delay of the UE over the same data/paging traffic arrival rate. A MATLAB simulation program is used to validate the system model and the numerical analysis. Analytical and numerical results are considered.

“…Next paper entitled BPerformance Evaluation for Delay Time Estimation in IEEE 802.16 m Sleep Mode,^by Lee et al [6], evaluated the delay time estimation in the sleep mode of IEEE 802.16 m by using M/D/1 queueing system with vacations and simulations under various traffic models. Their research offered solution to calculate the delay time with Poisson arrivals and experimental results to find parameters of power saving mechanisms based on arriving packet characteristic.…”
