Reconfigurable Intelligent Surfaces for Wireless Energy Transfer in IoT: A Survey on Architectures, Applications, and Open Challenges

Radio-frequency wireless energy transfer (RF-WET) has emerged as a promising solution for extending the lifetime of energy-constrained Internet of Things (IoT) devices, particularly in large-scale, obstructed, and hard-to-access deployments. However, practical RF-WET systems are limited by severe propagation losses, bl...

RIS-Assisted Industrial URLLC With Interference-Aware Max-Matching Diversity

The results show that MMD closely outperforms fixed and random allocation and closely follows the single-user proportional fair (PF) benchmark, while RRH cooperation, frequency diversity, dominant-interferer protection, additional transmit antennas, and larger RIS sizes improve reliability and effective goodput.
