Intelligent reflecting surface (IRS) has been widely studied in recent years,it has emerged as a new technology which can reflect the incident signal byintelligently configuring the reflection elements, thus changing the signalpropagation environment, enhancing the signals users desire and suppressing theinterference between users. In this paper, we study an IRS aided multi-userswireless communication where the base station (BS) sends a variety of signals,each user receives desired signals. In order to guarantee the fairness ofwireless communications, we need to maximize the minimum rates of users,subject to the power constraint of BS and the phase constraint of IRS. Priorworks on IRS mainly consider optimizing BS beamforming and IRS passivebeamforming, this paper also aims to optimize the IRS location. The consideredproblem is shown to be non-convex, we decompose the problem into twosubproblems, transforming the two subproblems into a lower bound problem andusing alternating optimization (AO) and successive convex approximation (SCA)to solve them, respectively. Finally, the two subproblems are optimizedalternately to make the objective function value converge in an acceptablerange. Simulation results verify the convergence results of our proposedalgorithm, and the performance improvement compared with the benchmark schemein wireless communication system.
