The rapid development of real-time Industrial Internet of Things (IoT) applications including green infrastructure, smart grids, smart city, intelligent transport networks, etc. enables Green communication between tens of billions of end devices such as wearable devices and sensors. The forthcoming sixth-generation (6G) experiences a new paradigm shift from connected things” to “connected intelligence”, which has limitations on spectrum, energy, cost and size. Ambient backscatter communication (AmBC) and Intelligent Reflecting Surface (IRS) I have been identified as the promising technologies to meet the above demands. AmBC is attractive because it does not require a dedicated RF carrier emitter. Instead, it exploits ambient signals from existing wireless infrastructure and devices, such as radio towers, television (TV) towers, cellular base stations, and wireless fidelity (Wi-Fi) access points. In addition, RIS can facilitate the reconfiguration of the wireless propagation environment by steering the incident signal through beamforming. Therefore, AmBC and RIS have attracted wide range of research from both academia and industry.

The goal of this research topic is to solicit original research papers, bringing together academic researchers and industrialists to report recent research advances in AmBC and IRS for 6G. The scope, mode, and quality of services can be greatly improved by AmBC and IRS enabled 6G, which has effectively promoted intelligent development and helped use limited resources more efficiently. In light of the future interest in critical 6G-enabled holographic communication, this Special Issue welcomes research that discusses channel modeling, fading performance analysis, transmission scheme design, resource allocation, and communication protocols of AmBC and IRS for 6G and to envision new research directions in the emerging fields of research.
