Abstract The Internet of Things (IoT) has revolutionized how we live and work by connecting
everyday devices to the Internet. As the demand for IoT devices grows, a reliable and …

Recently, massive machine-type communications (mMTCs) have become one of key use
cases for 5G. In order to support massive users transmitting small data packets at low rates …

Space–air–ground-integrated networks (SAGINs) are receiving a lot of attention as a
candidate for an extension to nonterrestrial networks beyond the limit of terrestrial networks …

Shortening the packet length has been a consensus in wireless network design for
supporting the ultra-low latency Internet of Things (IoT) applications. Yet, with short-packet …

The significant expansion of cellular networks has increased their potential to support a wide
range of use cases beyond their original purpose of providing broadband access. One such …

Delivering as many data packets as possible and making the life time of the network as long
as possible is one fundamental request for battery-driven wireless network design, where …

The emergence of various commercial and industrial Internet of Things (IoT) devices has
brought great convenience to people's life and production. Both low-power, massively …

Grant-free (GF) random access is a promising technique to support massive machine-type
communication (mMTC) systems. Due to the conflicts, the performance is degraded. The …
