Enhanced Random Access for Massive-Machine-Type Communications

IEEE Internet of Things Journal, 2021
In this article, we study a random access (RA) scheme to alleviate the RA channel (RACH) overload problem in the massive-machine-type communication (mMTC) environment. We first propose a timing advance-based preamble resource expansion (TAPRE) scheme which effectively increases preamble resources and reduces the preamble collision probability by ...

Rate-Splitting Assisted Massive Machine-Type Communications in Cell-Free Massive MIMO

open access: yesIEEE Communications Letters, 2022
This letter focuses on integrating rate-splitting multiple-access (RSMA) with time-division-duplex Cell-free Massive MIMO (multiple-input multiple-output) for massive machine-type communications. Due to the large number of devices, their sporadic access behaviour and limited coherence interval, we assume a random access strategy with all active devices

A secure Device-to-Device communication scheme for massive Machine Type Communication

Computers & Security, 2021
Abstract Massive Machine Type Communication (mMTC) services aims to provide universal connectivity to thousands of low-power, low-cost devices with the support of 5G cellular networks. Device to Device (D2D) communication under 5G cellular network envisages interaction among heterogeneous and previously un-associated devices with diverse requirements,
