Modeling DRX for D2D Communication
IEEE Internet of Things Journal, 2021Discontinuous reception (DRX) has been included in 4G-LTE as the main power saving mechanism for user equipment (UE). However, the existing 3-state DRX model is not sufficient for new use cases introduced by 4G and 5G. For example, the device discovery process in device to device (D2D) communication has a significant impact on delay and power ...

Comparative Study of Power Saving and Delay in LTE DRX, Directional-DRX and Hybrid-Directional DRX
Wireless Personal Communications, 2017With integration of advanced long term evolution networks (LTE networks) in mobile technology, 5G networks are introduced due to broadband spectrum extension which requires higher power consumption. Discontinuous reception (DRX) sleep mode mechanism is provided to accommodate lower power consumption of user equipment terminals (UEs).

Accurate Modeling of the DRX Mechanism with Predetermined DRX Cycles Based on the 3GPP LTE Standard
Mobile Networks and Applications, 2015In Long Term Evolution-Advanced (LTE-A), the Discontinuous Reception (DRX) mechanism conserves the power of a User Equipment (UE) by monitoring the UE's downlink channels for a specific period and turning off the UE's radio when no packets arrive during the period.

Exploring Flexibility of DRX in LTE/LTE-A: Design of Dynamic and Adjustable DRX
IEEE Transactions on Mobile Computing, 2018Only two types of sleep cycles with two fixed sleep periods are defined in the standard of the discontinuous reception (DRX) mechanism in LTE/LTE-A. Explicitly, such a DRX mechanism is simple but lacks flexibility. To provide flexibility, two types of dynamic and adjustable DRX (DADRX) mechanisms are proposed and investigated in this paper.

(Invited) Drx and Drx+ As Earth-Abundant Inexpensive Cathodes
ECS Meeting Abstracts, 2022Scaling the Li-ion industry to multiple TWh/year will be challenging with NMC-class cathodes because of the cost and resource constraints arising from the use of nickel and/or cobalt. Disordered rocksalt cathodes DRX can be synthesized with almost any transition metal and offer a likely alternative to replace Ni-containing layered cathode materials.

Flexible DRX Optimization for LTE and 5G
IEEE Transactions on Vehicular Technology, 2020With the advancement of the next generation of cellular systems, flexible mechanisms for Discontinuous Reception (DRX) are needed in order to save energy. 5G will bring heterogeneous packet sizes and traffic types, as well as an increasing need for energy efficiency. The current static DRX mechanism is inadequate to meet these needs.

Standard operation procedure for switchSENSE DRX systems
European Biophysics Journal, 2021There is currently a large panel of technologies available to address molecular interactions in vitro. Each technology presents individual advantages and drawbacks, and it becomes challenging to choose which technology will be best suited for a molecular interaction of interest. Approaches can be broadly categorized as either microfluidic surface-bound

Revitalizing DRX for enhanced mobile sleep modes
Computer Communications, 2019Abstract A flexible Discontinuous Reception (DRX) scheme is proposed to resolve the drawbacks of State-of-the-Art (SOTA) DRX scheme by eliminating the need of major timers and allowing Intra-Subframe Micro (ISM) sleep periods. The proposed new Timer Eliminating DRX (TE-DRX) scheme was tested and analyzed with traffic logs from live mobile network ...

IEEE Wireless Communications Letters, 2016
Energy-efficiency is a crucial requirement for future 5G radio devices. Discontinuous reception (DRX) is a mechanism for power saving in LTE/LTE-A standard. In this letter, a method is developed to compute the mean queuing delay induced by the DRX. In contrast to existing semi-Markovian models, an approach, which combines Markov chains and regenerative

DRX mechanism for power saving in LTE
IEEE Communications Magazine, 2009Enhanced discontinuous reception mode is supported in long term evolution of 3GPP standards to conserve the mobile terminal's battery power. Furthermore, there are additional advantages in using DRX, such as over-the-air resource saving on both the uplink and downlink to increase overall system capacity. One of the enhancements over 3G wireless systems
