The Intelligent Reflecting Surface (IRS) represents a revolutionary technology for effectively enhancing the performance of Internet-of-Things (IoT) networks owing to its ability of customizing the wireless propagation environment and compatibility with advanced communication techniques, such as non-orthogonal multiple-access (NOMA). This paper investigates the impact of imperfect channel state information (CSI) on the achievable data rate of IRS-Aided downlink NOMA-enabled IoT framework over Rician fading channels. Specifically, the imperfect CSI is considered from the IRS to the IoT devices. The results demonstrated that imperfect CSI has a significant impact on the achievable rate performance of the far and near IoT devices, which are also different under different numbers of reflecting units.
