Intelligent Reflecting Surface (IRS) is a revolutionary technology which is able to improve the performance of wireless data transmission system. Specially, large numbers of small reflecting unit are jointly adjusted to reconfigure the wireless signal transmitting environment. In this paper, we study the use of IRS in a multi-user MIMO system where IRS is deployed to assist the data transmission in both uplink and downlink phases. We first present an overview of the technology of intelligent surfaces, including its fundamental principles and practical applications. Then we derive the signal model of IRS aided multi-user MIMO system and provide data transmission schemes. Finally, numerical results are demonstrated to show the superb signal enhancement with the use of intelligent surfaces in wireless system.
