Massive machine-type communications in 5g: physical and MAC-layer solutions
Carsten Bockelmann,Nuno K. Pratas,Hosein Nikopour,Kelvin Kar Kin Au,Tommy Svensson,Cedomir Stefanovic,Petar Popovski,Armin Dekorsy +7 more
TL;DR: The PHY and MAC layer solutions developed within METIS to address the main challenge in mMTC is scalable and efficient connectivity for a massive number of devices sending very short packets.
Journal ArticleDOI
Towards Massive Connectivity Support for Scalable mMTC Communications in 5G Networks
Carsten Bockelmann,Nuno K. Pratas,Gerhard Wunder,Stephan Saur,Monica Navarro,David Gregoratti,Guillaume Vivier,Elisabeth de Carvalho,Yalei Ji,Cedomir Stefanovic,Petar Popovski,Qi Wang,Malte Schellmann,Evangelos Kosmatos,Panagiotis Demestichas,Miruna Raceala-Motoc,Peter Jung,Slawomir Stanczak,Armin Dekorsy +18 more
TL;DR: In this article, the authors present an overview of different physical and medium access techniques to address the problem of a massive number of access attempts in mMTC and discuss the protocol performance of these solutions in a common evaluation framework.
Journal ArticleDOI
Compressive sensing based multi-user detection for machine-to-machine communication
TL;DR: The sporadic nature of machine‐to‐machine communication, low data rates, small packets and a large number of nodes necessitate low overhead communication schemes that do not require extended control signaling for resource allocation and management.
Proceedings Article
Exploiting Sparsity in Channel and Data Estimation for Sporadic Multi-User Communication
TL;DR: This paper investigates how to adapt several approaches to channel estimation, such that they are suitable for this joint detection and estimation of Compressive Sensing detectors in Multi-User Detection.
Proceedings ArticleDOI
Compressive Sensing Multi-User Detection for Multicarrier Systems in Sporadic Machine Type Communication
TL;DR: The new combined scheme MCSM with its flexibility in accessing time frequency resources additionally allows for either reducing the number of subcarriers or shortening the multicarrier symbol duration, i.e., the authors gain a high spectral efficiency.
