We propose a cellular architecture that combines multiuser MIMO downlink with
opportunistic use of unlicensed Industrial, Scientific, and Medical Radio (ISM) bands to …

The integration of local device-to-device (D2D) communications and cellular connections
has been intensively studied to satisfy co-existing D2D and cellular communication demand …

To handle increased capacity demands, sophisticated MIMO-based transmission strategies,
based on transmitter cooperation, have emerged. However, different types of users' …

This letter considers the downlink of a cellular network with an asymmetric antenna
configuration, where virtual multiple-input multiple-output (MIMO) is formed with receive …

A distributed MIMO system consists of several access points connected to a central server
and operating as a large distributed multi-antenna access point. In theory, such a system …

This paper provides an analytical performance characterization of both the uplink (UL) and
downlink (DL) user-centric network multiple-input multiple-output (MIMO) systems, where a …

Device-to-device (D2D) relaying is a concept, where some users relay data of cell-edge
users (CUEs) experiencing a bad channel quality to a base station. While this research topic …

This paper provides an analytical performance characterization of user-centric cooperation
for network multiple-input multiple-output (MIMO) systems, where base-stations (BSs) form …

In this paper, we consider a cooperative device-to-device (D2D) communication system,
where the D2D transmitters (DTs) act as relays to assist the densified cellular network users …

We develop two distributed downlink resource allocation algorithms for user-centric, cell-
free, spatially-distributed, multiple-input multiple-output (MIMO) networks. In such networks …
