Exploiting Spatial Correlation for Pilot Reuse in Single-Cell mMTC [PDF]

open access: yes2021 IEEE 32nd Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2021
As a key enabler for massive machine-type communications (mMTC), spatial multiplexing relies on massive multiple-input multiple-output (mMIMO) technology to serve the massive number of user equipments (UEs). To exploit spatial multiplexing, accurate channel estimation through pilot signals is needed.

Jointly Sparse Support Recovery via Deep Auto-encoder with Applications in MIMO-based Grant-Free Random Access for mMTC

open access: yes, 2020
In this paper, a data-driven approach is proposed to jointly design the common sensing (measurement) matrix and jointly support recovery method for complex signals, using a standard deep auto-encoder for real numbers.

Massive MIMO for Internet of Things (IoT) Connectivity

open access: yes, 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 ...

Sensing and Secure NOMA-Assisted mMTC Wireless Networks

open access: yesElectronics, 2023
Throughout this study, a novel network model for massive machine-type communications (mMTC) is proposed using a compressive sensing (CS) algorithm and a non-orthogonal multiple access (NOMA) scheme. Further, physical-layer security (PLS) is applied in this network to provide secure communication. We first assume that all the legitimate nodes operate in

Hybrid Services Collaborative Resource Scheduling Strategy towards Artificial Intelligence of Things

open access: yesApplied Sciences, 2023
The increasing number of Artificial Intelligence of Things (AIoT) devices at the edge layer brings serious challenges to the traditional access network architecture, which results in a decrease in data transmission due to different QoS requirements.

Grouping-Based Random Access Collision Control for Massive Machine-Type Communication

open access: yes, 2017
Massive Machine-Type Communication (mMTC) is expected to be strongly supported by future 5G wireless networks. Its deployment, however, is seriously challenged by the high risk of random access (RA) collision. A popular concept is to reduce RA collisions

Legal Protection for Consumers in the MMTC Market

open access: yesJournal of Legal and Cultural Analytics, 2023
Consumer protection at this time can be separated from trading activities. It is hoped that this trading activity will create a balance of rights and obligations between business actors and consumers. The countries that are now called developed countries have gone through three levels of development.
