TL;DR: A system that uses compressive estimation on the uplink to configure precoders and combiners for the downlink in a millimeter wave multiuser multiple-input multiple-output system is developed.

TL;DR: In this article, the authors jointly address user scheduling and precoder/combiner design in the downlink of a wideband millimeter-wave communications system, and propose an algorithmic solution based on the linear successive allocation, which greedily allocates streams to different users and computes the corresponding precoders and combiners.

TL;DR: This work considers the utilization of time-modulated arrays (TMAs) as a simple and cost-effective approach to hybrid digital–analog precoding in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems and compares TMA precoders to those implemented with conventional VPSs in terms of insertion losses, chip area, and cost.

TL;DR: An intelligent reflective surface (IRS) is a real-time controllable reflectarray with a massive number of low-cost passive elements which introduce a phase shift to the incoming signals from the sources before the propagation towards the destination.

TL;DR: This work proposes an algorithmic joint solution for the transmit filter design and the power allocation in this work and employs a duality between Multiple Access Channel (MAC) and BC rate regions and the so-called standard interference functions.
