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 Connectivity With Massive MIMO—Part II: Achievable Rate Characterization [PDF]

IEEE Transactions on Signal Processing, 2018
This two-part paper aims to quantify the cost of device activity detection in an uplink massive connectivity scenario with a large number of devices but device activities are sporadic. Part I of this paper shows that in an asymptotic massive multiple-input multiple-output (MIMO) regime, device activity detection can always be made perfect.

Massive MIMO for Internet of Things (IoT) connectivity [PDF]

Physical Communication, 2019
Massive MIMO is considered to be one of the key technologies in the emerging 5G systems, but also a concept applicable to other wireless systems. Exploiting the large number of degrees of freedom (DoFs) of massive MIMO essential for achieving high spectral efficiency, high data rates and extreme spatial multiplexing of densely distributed users. On the

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.

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 ...
