Massive machine-type communications (mMTC) is one of the main three focus areas in the
5th generation (5G) of wireless communications technologies to enable connectivity of a …

Multiple access technology played an important role in wireless communication in the last
decades: it increases the capacity of the channel and allows different users to access the …

To account for the massive uncoordinated random access scenario, which is relevant for the
Internet of Things, Polyanskiy et al.(2017) proposed a novel formulation of the multiple …

In this paper, we consider mission-critical task offloading in the non-orthogonal multiple
access (NOMA)-assisted mobile edge computing (MEC) networks, where local information …

Consider a random access communication scenario over a channel whose operation is
defined for any number of possible transmitters. As in the model recently introduced by …

We extend the seminal work by Polyanskiy (2017) on massive uncoordinated access to the
case where the number of active users is random and unknown a priori. We define a random …

This work studies point-to-point, multiple access, and random access lossless source coding
in the finite-blocklength regime. In each scenario, a random coding technique is developed …

A new converse bound is presented for the two-user multiple-access channel under the
average probability of error constraint. This bound shows that for most channels of interest …

In this paper, we study multiple-antenna wireless communication networks, where a large
number of devices simultaneously communicate with an access point. The capacity region of …

This paper presents finite-blocklength achievability bounds for the Gaussian multiple access
channel (MAC) and random access channel (RAC) under average-error and maximal-power …
