As 5G networks are being rolled out in many different countries nowadays, the time has
come to investigate how to upgrade and expand them toward 6G, where the latter is …

In this work, we present a joint channel estimation, activity detection and data decoding
scheme for massive machine-type communications. By including the channel and the a …

This paper investigates multiple access schemes for uplink and downlink transmissions in
cellular networks with massive Internet of Things (IoT) devices. Recall that single-carrier …

In this paper, we study how to efficiently and reliably detect active devices and estimate their
channels in a multiple-input multiple-output orthogonal frequency-division multiplexing …

In this paper, we study the high-dimensional multiple-measurement-vector (MMV) problem,
which typically arises in massive machine-type communications (mMTC) that operates with …

Low earth orbit (LEO) satellite has been considered as a potential supplement for the
terrestrial Internet of Things (IoT). In this paper, we consider grant-free non-orthogonal …

In this paper, we extend the bilinear generalized approximate message passing (BiG-AMP)
approach, originally proposed for high-dimensional generalized bilinear regression, to the …

As industrial plants increase the number of wirelessly connected sensors for fault detection,
a key problem is to identify and obtain data from the sensors. Due to the large number of …

In the massive machine-type communication (mMTC) scenario, a large number of devices
with sporadic traffic need to access the network on limited radio resources. Recently, grant …

Cell-free communication has the potential to significantly improve grant-free transmission in
massive machine-type communication, wherein multiple access points jointly serve a large …
