Massive Machine-Type Communication (mMTC) Access with Integrated Authentication [PDF]

2017 IEEE International Conference on Communications (ICC), 2017
We present a connection establishment protocol with integrated authentication, suited for Massive Machine-Type Communications (mMTC). The protocol is contention-based and its main feature is that a device contends with a unique signature that also ...

NOMA-Based Random Access in mMTC XL-MIMO

IEEE Access, 2023
In machine-type communication (MTC), massive access attempts are generated and the massive MIMO is the key technology to support this demand. To support massive MTC (mMTC), the recent extra-large scale massive multiple-input multiple-output (XL-MIMO ...

Biosynthesis of the Fully Saturated C₁₆ Homosesquiterpene Descartane Through Deprotonation With Cyclopropanation. [PDF]

Angew Chem Int Ed Engl
A non‐canonical C16 sesquiterpene synthase from Morganella morganii produces the unusual scaffold descartane. Its cyclisation mechanism was rationalised by isotopic labelling experiments and DFT calculations. Site‐directed mutagenesis altered enzyme function, resulting in alternative products, including voltairene, which requires a different ...

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Modeling and Analysis of mMTC Traffic in 5G Base Stations [PDF]

2022 IEEE 19th Annual Consumer Communications & Networking Conference (CCNC), 2022
Massive Machine-Type Communications (mMTC) are one of the three types of services that should be supported by 5G networks. These are distinguished by the need to serve a large number of devices which are characterized by nonintensive traffic and low energy consumption. While the sporadic nature of the mMTC traffic does not pose an exertion to efficient
