Non-Orthogonal Contention-Based Access for URLLC Devices with Frequency Diversity [PDF]
, 2019 We study coded multichannel random access schemes for ultra-reliable low-latency uplink transmissions. We concentrate on non-orthogonal access in the frequency domain, where users transmit over multiple orthogonal subchannels and inter-user collisions ...

Exploiting Spatial Correlation for Pilot Reuse in Single-Cell mMTC [PDF]
2021 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.

Sensing and Secure NOMA-Assisted mMTC Wireless Networks
Electronics, 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

Legal Protection for Consumers in the MMTC Market
Journal 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.
