Hybrid access control mechanism for massive machine type communications
Discover Internet of ThingsAbstract Massive Machine Type Communications (mMTC) are integral to the Internet of Things (IoT) ecosystem, requiring efficient and reliable access control mechanisms to manage the enormous number of connected devices. Traditional access control schemes such as Dynamic Resource Allocation (DRA), Slotted Aloha, and Carrier Sense Multiple Access with ...

Massive Access for Massive Machine-Type Communication
La comunicación masiva de tipo máquina (mMTC) es uno de los tres escenarios de aplicación típicos de los sistemas 5G y futuros 6G. Para satisfacer los requisitos de acceso aleatorio de un número masivo de dispositivos, se adoptan ampliamente esquemas de acceso aleatorio sin concesión (grant-free). Sin embargo, cuando el conjunto de dispositivos activos

Massive Machine-Type Communication and Satellite Integration for Remote Areas [PDF]
IEEE Wireless Communications, 2021 Despite immense progress along different tracks, wireless connectivity for machine applications in remote areas is still very challenging. To address this vital need, in this article, we discuss and advocate the convergence between low-pow-er wide area network (LPWAN) grade massive machine-type communication (mMTC) wireless technologies and satellite ...

Enhanced Random Access for Massive-Machine-Type Communications
IEEE Internet of Things Journal, 2021In this article, we study a random access (RA) scheme to alleviate the RA channel (RACH) overload problem in the massive-machine-type communication (mMTC) environment. We first propose a timing advance-based preamble resource expansion (TAPRE) scheme which effectively increases preamble resources and reduces the preamble collision probability by ...

Pilot beamforming for massive machine type communication systems
2017 IEEE/CIC International Conference on Communications in China (ICCC), 2017In this paper, we propose a novel pilot beamforming and CSI acquisition strategy for machine-type-communication systems to achieve reduction in pilot overhead and improve the channel estimation performance. Key idea of the proposed beam-forming technique is to sparsify the time-domain channel vector using the beamforming.
