Optimistic DRX for machine-type communications
2016 IEEE International Conference on Communications (ICC), 2016In Long Term Evolution-Advanced (LTE-A) network, Machine Type Communications (MTC) allows machines to transfer data with almost no human intervention. In MTC, power saving is one of the most important issues. In the meantime, the 3rd Generation Partnership Project (3GPP) proposes Discontinuous Reception (DRX) mechanism to allow user equipments (UEs) to

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

Service aware adaptive DRX scheme
2014 IEEE Globecom Workshops (GC Wkshps), 2014Discontinuous Reception (DRX) in Long Term Evolution (LTE) is used to reduce the energy consumption when there is no data transfer for a given user. Current DRX works on a per-UE basis but works with fixed DRX. That is, DRX does not take into account that different services and different terminals have different requirements on Quality of Experience ...

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

Modeling of LTE DRX in RRC Idle state
2017 IEEE 22nd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2017In LTE/LTE-A the Discontinuous Reception (DRX) mechanism is the main approach for power saving in User Equipments (UEs) when in Connected and Idle mode. In this paper, an Idle mode DRX mechanism model is proposed also enabling evaluation of closely related mechanisms such as paging and Tracking Area Update (TAU).

Alloy Digest, 2005
Abstract DRX is similar to AISI S7. It has a higher carbon content and is alloyed with 3.25% Cr and 1.4% Mo for emphasis on good wear resistance. DRX is typically used for inserts or smaller molds in applications requiring high production volume, or molds subjected to high-wear condition.

Performance analysis and optimization of DRX mechanism in LTE
2012 3rd IEEE International Conference on Network Infrastructure and Digital Content, 2012To extend user equipment (UE) battery's lifetime, discontinuous reception (DRX) mechanism is employed in Long Term Evolution (LTE) system. In this paper, we propose an analytical model which mainly focuses on the inactivity period. Based on the model, a cost function that considers both energy consumption and response delay is presented.

Performance Analysis and Adaptive DRX Scheme for Dual Connectivity
IEEE Internet of Things Journal, 2019The 3GPP (Rel.12 and Rel.16) introduces and explores the dual connectivity (DC). It is one of the most important future technologies adopted by 5G. It enhances the throughput and mobility robustness by enabling simultaneous dual connections with macro and small-cell evolved NodeBs (eNBs). While aggregating spectrum with the dual connections, DC induces

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 ...

DRX-Aware Scheduling Method for Delay-Sensitive Traffic
IEEE Communications Letters, 2010The Long Term Evolution (LTE) system adopts Discontinuous Reception (DRX) in the link level for power saving to extend the battery life of the User Equipment (UE). A novel real-time DRX-aware scheduling method is proposed for delay-sensitive services in wireless downlink systems.
