Massive MIMO With Massive Connectivity for Industrial Internet of Things

IEEE Transactions on Industrial Electronics, 2020
In this paper, we investigate the feasibility of using massive multi-in multi-out (MIMO) to provide connectivity to Industrial Internet of Things (IIoT) wirelessly. Single-cell massive MIMO is used to support a large number of low-power IIoT devices in the uplink simultaneously.

Massive device connectivity with massive MIMO

2017 IEEE International Symposium on Information Theory (ISIT), 2017
This paper studies a single-cell uplink massive device communication scenario in which a large number of single-antenna devices are connected to the base station (BS), but user traffic is sporadic so that at a given coherence interval, only a subset of users are active. For such a system, active user detection and channel estimation are key issues.

Cascaded Scheduling Scheme for Massive Multi-Connectivity

2021 Wireless Days (WD), 2021
Industrial applications pose strict requirements on latency and reliability performance of communication systems. Not all of these requirements can be met by current wireless communication standards. A promising solution to enhance latency and reliability performance of wireless communication systems is Multi-Connectivity (MC), i.e., using multiple ...

Massive connectivity with machine learning for the Internet of Things

Computer Networks, 2021
Abstract Driven by the need to ensure the connectivity of an unprecedentedly huge number of IoT devices with no human intervention the issues of massive connectivity have recently become one of the main research areas in IoT studies. Conventional wireless communication technologies are designed for Human-to-Human (H2H) communication which leads to ...

Matrix Balancing on a Massively Parallel Connection Machine

ORSA Journal on Computing, 1990
Matrix balancing models find applications in economics, transportation, regional sciences, statistics, stochastic modeling and other areas. The iterative scaling algorithm RAS that is used for the solution of these problems is shown here to be suitable for data level parallelism on the Connection Machine (CM).

On the fundamental limits of massive connectivity

2017 Information Theory and Applications Workshop (ITA), 2017
This paper aims to provide an information theoretical analysis of massive device connectivity scenario in which a large number of devices with sporadic traffic communicate in the uplink to a base-station (BS). In each coherence time interval, the BS needs to identify the active devices, to estimate their channels, and to decode the transmitted messages
