“…In the Industry 4.0 era, wireless communications will play a key role in providing broadband connections for up to tens of billions of Internet of ings (IoT) devices. While existing technologies are hardly capable of meeting the spectrum requirements for such a large number of wireless devices, the in-band full-duplex (IBFD) communication technology which can double the spectrum e ciency is a promising solution [1][2][3][4][5][6][7][8][9][10][11]. However, although large e orts have been made recently to produce IBFD wireless devices, it is widely known that this type of communication is still a ected by residual self-interference (RSI) due to imperfect self-interference cancellation (SIC) [2][3][4]12].…”

“…However, although large e orts have been made recently to produce IBFD wireless devices, it is widely known that this type of communication is still a ected by residual self-interference (RSI) due to imperfect self-interference cancellation (SIC) [2][3][4]12]. According to recent reports, the latest SIC techniques can achieve up to 110 dB attenuation by various methods such as isolation, wireless propagation domain suppression, and analog and digital cancellation [8,12,13]. e work in [14] further demonstrated that additional 36 dB attenuation can be achieved for self-interference (SI) suppression if a suitable combination of SI removal and largescale antenna linear processing (LALP) method is used.…”

“…However, more e orts still need to be done to achieve better RSI suppression. Wireless relaying is an emerging technology which can be used to improve coverage, reliability, and spectrum efciency has recently become a hot research topic [1,[3][4][5][6][7][8][9][10][11][15][16][17].

In this paper, we analyze the performance of a full-duplex (FD) amplify-and-forward (AF) relay system with imperfect hardware. Besides the aggregate hardware impairments of the imperfect transceiver, we also consider the impact of residual self-interference (RSI) due to imperfect cancellation at the FD relay node. An analytical framework for analyzing the system performance including exact outage probability (OP), asymptotic OP, and approximate symbol error probability (SEP) is developed. In order to tackle these impacts, we propose an optimal power allocation scheme which can improve the outage performance of the FD relay node, especially at the high signal-to-noise ratio (SNR) regime. Numerical results are presented for various evaluation scenarios and veri ed using the Monte Carlo simulations.

Summary It has been confirmed by many scientists and industrial experts that intelligent reflecting surface (IRS) should be one of the key enabling technologies for sixth‐generation (6G) wireless networks. This paper analyzes the performance of an IRS‐aided full‐duplex (FD) amplify‐and‐forward wireless relay (AFR) network, where the IRS is exploited to enhance the quality of the channel from the source to the relay. We successfully derive the analytical expressions of outage probability (OP), achievable data rate (ADR), and symbol error probability (SEP) of the considered IRS‐FD‐AFR network over Rayleigh fading channel. The corresponding expressions of the IRS‐aided half‐duplex (HD) AFR (IRS‐HD‐AFR) system are also derived as a benchmark to compare. The results demonstrate that the performance of both IRS‐FD‐AFR and IRS‐HD‐AFR systems are greatly improved by increasing the number of reflecting elements ( L) in the IRS. All derived expressions are validated by Monte Carlo simulations.

Joint altitude, power control, and bandwidth allocation optimization for unmanned aerial vehicle‐enabled reliable communications

Unmanned aerial vehicles (UAVs) as aerial relays have found many applications in the current communication network. Since the air‐to‐ground (AtG) link differs from the terrestrial link, ensuring a reliable AtG transmission remains to be a meaningful issue. This article investigates that a UAV works as an aerial relay to forward information from multiple access points to multiple remote base stations in an emergency situation. Using the full‐duplex decode‐and‐forward relaying mode, we formulate a problem to minimize the maximum outage probability among all links, jointly optimizing the UAV altitude, power control, and bandwidth allocation. The outage probability function takes into account the line‐of‐sight probability‐based AtG fading and the self‐interference introduced by full‐duplex relaying, both of which make our formulated problem nonconvex. We reformulate the outage probability function into a more tractable function. Then, we decouple the original problem into two subproblems, that is, altitude optimization as well as power control and bandwidth allocation. Each subproblem is solved by the successive convex optimization technique, and an overall iteration algorithm is proposed to solve the original problem based on the block coordinate descent theory. Simulation results reveal the reliability gain of our proposed algorithm compared with our designed benchmark. Besides, the optimal UAV three‐dimensional location that minimizes the global min‐max outage probability is found by numerical simulations. Finally, the average throughput gain can also be obtained by our proposed algorithm.
