This is Part 1 of a tutorial from GLOBECOM 2021, presented by Professor Emil Björnson, KTH Royal Institute of Technology.
Abstract: In this tutorial, we introduce a new promising paradigm for 6G by leveraging a massive number of low-cost passive elements with independently controllable reflection amplitude and/or phase, named Intelligent Reflecting Surface (IRS), which is able to smartly reconfigure wireless channels for enhancing the communication performance. The tutorial consists of two parts. In the first part, we present the signal and channel models of IRS by taking into account its hardware constraints in practice. We then illustrate the main functions and applications of IRS in achieving spectral and energy efficient wireless networks, and highlight its cost and performance advantages as compared to existing wireless technologies such as ultra-dense network, massive MIMO, etc. We also present the results on recently developed prototypes and conducted experiments on IRS as well as its related industry activities.
