TL;DR: This paper evaluates the relevant PHY and MAC techniques for their ability to improve the reliability and reduce the latency and identifies that enabling long-term evolution to coexist in the unlicensed spectrum is also a potential enabler of URLLC in theUnlicensed band.

TL;DR: In this paper, a new mmWave-NOMA transmission scheme for cellular machine-to-machine (M2M) communication systems for IoT applications is introduced, which is based upon the distance between the BS and the MTC devices aiming at reducing the system overall overhead for massive connectivity and latency.

TL;DR: This paper reveals that the NOMA techniques have evolved from single-carrier NomA (SC-NOMA) into multi- carrier NOMa (MC-N OMA), and comprehensively investigated on the basic principles, enabling schemes and evaluations of the two most promising MC-NomA techniques, namely sparse code multiple access (SCMA) and pattern division multiple access(PDMA).

TL;DR: Numerical results verify that massive MU-MIMO can support a large number of UL URLLC users even when users are randomly deployed under shadow fading, and finite blocklength (FBL) information theory is utilized to derive the error probability of accessing users with a given latency.

TL;DR: A closed-form upper bound for the delay target violation probability in the downlink MIMO-NOMA is derived by applying stochastic network calculus to the Mellin transforms of service processes and it is proved that the infinite-length Mellin transform resulting from the non-negligible interferences of NOMA are Cauchy convergent and can be asymptotically approached by a finite truncated binomial series in the closed form.
