Summary
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.

Recent Advances in Backscatter and Intelligent Reflecting Surface Communications for 6G-enabled Internet of Things Networks)
Abstract In wireless communications, the Ambient Backscatter Communication (AmBC) technique is a promising
approach, detecting user presence accurately at low power levels. At low power or a low Signal-to-Noise Ratio
(SNR), there is no dedicated power for the users. Instead, they can transmit information by reflecting the ambient
Radio Frequency (RF) signals in the spectrum. Therefore, it is essential to detect user presence in the spectrum for
the transmission of data without loss or without collision at a specific time. In this paper, the authors proposed a
novel Spectrum Sensing (SS) detection technique in the Cognitive Radio (CR) spectrum, by developing…

Abstract The rapid advancement of Internet of Things (IoT) technology has brought convenience to people’s lives; however further development of IoT faces serious challenges, such as limited energy and shortage of network spectrum resources. To address the above challenges, this study proposes a simultaneous wireless information and power transfer IoT adaptive time slot resource allocation (SIATS) algorithm. First, an adaptive time slot consisting of periods for sensing, information transmission, and energy harvesting is designed to ensure that the minimum energy harvesting requirement is met while the maximum uplink and downlink throughputs are obtained. Second, the optimal transmit power and channel assignment…

Recent Advances in Backscatter and Intelligent Reflecting Surface Communications for 6G-enabled Internet of Things Networks)
Abstract Hardware impairments (HI) are always present in low-cost wireless devices. This paper investigates the outage behaviors of intelligent reflecting surface (IRS) assisted non-orthogonal multiple access (NOMA) networks by taking into account the impact of HI. Specifically, we derive the approximate and asymptotic expressions of the outage probability for the IRS-NOMA-HI networks. Based on the asymptotic results, the diversity orders under perfect self-interference cancellation and imperfect self-interference cancellation scenarios are obtained to evaluate the performance of the considered network. In addition, the system throughput of IRS-NOMA-HI is discussed in delay-limited mode. The obtained results are provided to verify the accuracy of…

Abstract In this paper, we consider a downlink non-orthogonal multiple access (NOMA) network assisted by two reconfigurable intelligent surfaces (RISs) over Rician fading channels, in which each user communicates with the base station by the virtue of a RIS to enhance the reliability of the received signal. To evaluate the system performance of our proposed RIS-NOMA network, we first derive the exact and asymptotic expressions for the outage probability and ergodic rate of two users. Then, we derive the exact and asymptotic upper bound expressions for the ergodic rate of the nearby user. Based on asymptotic analytical results, the diversity orders…

Abstract In this paper, we investigate the secrecy outage performance for the two-way integrated satellite unmanned aerial vehicle relay networks with hardware impairments. Particularly, the closed-form expression for the secrecy outage probability is obtained. Moreover, to get more information on the secrecy outage probability in a high signal-to-noise regime, the asymptotic analysis along with the secrecy diversity order and secrecy coding gain for the secrecy outage probability are also further obtained, which presents a fast method to evaluate the impact of system parameters and hardware impairments on the considered network. Finally, Monte Carlo simulation results are provided to show the efficiency…

Recent Advances in Backscatter and Intelligent Reflecting Surface Communications for 6G-enabled Internet of Things Networks)
Abstract In recent years, Internet of Things (IoT) technology has emerged and gradually sprung up. As the needs of large-scale IoT applications cannot be satisfied by the fifth generation (5G) network, wireless communication network needs to be developed into the sixth generation (6G) network. However, with the increasingly prominent security problems of wireless communication networks such as 6G, covert communication has been recognized as one of the most promising solutions. Covert communication can realize the transmission of hidden information between both sides of communication to a certain extent, which makes the transmission content and transmission behavior challenging to be detected by…
