User-IRS Association for Sum-Rate Maximization in Multi-IRS Aided Wireless Communication Networks
In this paper, we investigate the assignment of intelligent reflecting surfaces (IRSs) to user-base station (BS) pairs in a multi-IRS-assisted wireless communication network.Our objective is to optimize the allocation of one or more IRSs to each user-BS pair to maximize the overall sum-rate of the network.Using passive beamforming, the transmitted
