Weighted Sum Rate Maximization in IRS-BackCom Enabled Downlink Multi-Cell MISO Network

This letter investigates intelligent reflecting surface backscatter communication (IRS-BackCom) assisted downlink multi-cell multiple-input single-output network for the first time. In such multi-cell network, each IRS instead of active transmit antennas serves as a cell base station (BS) to communicate with its single-antenna users through modulation and backscatter of ambient wireless signal fro...
