“…IRS consists of a large number of reflective elements, which can be passive or active, ultra-low power elements, each of which can independently apply a continuous or discrete adjustable phase shifts to the incident signal [3], [4]. Besides, despite the experienced self-interference (SI), a two-user full duplex (FD) communication system allows users to simultaneously send and receive information over the same channel, rendering it a spectrally efficient mechanism [5], [6]. Therefore, it is anticipated that the integration of IRS into FD systems will bring up additional benefits in terms of spectrum and energy efficiencies.…”

Intelligent reflecting surface (IRS) has been deemed as an energy and spectral-efficient technology, that can potentially enhance network coverage and transmission reliability, with minimum impact on transceivers' complexity. Motivated by this, we develop a comprehensive analysis on the performance of integrating IRS into full-duplex (FD) cellular or Internet of Things (IoT) networks in both realistic Rician and Nakagami fadings. Firstly, in the context of reciprocal channels in Rician fadings, we derive the closed-form approximations of the users' outage probability (OP) and ergodic capacity (EC), under the non-central Chi-square distribution assumption on the signal-to-interference-plus-noise ratio (SINR). Further following by the Gamma distribution assumption on the SINR, we derive the cumulative distribution function (CDF) expression of the user's SINR, which is then leveraged to obtain simple yet effective closed-form expressions in terms of OP and EC. Subsequently, in Nakagami fading scenarios with the reciprocal and non-reciprocal channels, the closed forms of both users' OP and EC are obtained. Finally, the correctness of all the theoretical expressions is verified through substantial Monte Carlo simulations. The results indicate that the OP and EC deduced from Gamma distribution exhibit the fairly precise results for the arbitrary number of IRS elements, especially in Nakagami fadings.INDEX TERMS Full-duplex, intelligent reflecting surfaces, non-reciprocal, reciprocal, Rician and Nakagami fadings. Nakagami fading environment. In [22], Lu and Wang focused on the OP for an arbitrary IRS reflecting coefficient in an IRSaided two-way FD system, over correlated Rayleigh fading. Atapattu et al. [23] addressed the outage performance and spectral efficiency analyses for IRS-assisted two-way communication systems over Rayleigh fading channels. Apart from these, other literature relevant to IRS/RIS FD is summarized in Table 1, where the complex Gaussian (denoted as CN) assumptions are basically made about residual self-interference (RSI) or hardware impairment (HI). It is also noted that user, access point (AP) or relay can be in FD mode, allowing one or more FD nodes to coexist with other half-duplex(HD) nodes. Generally, one-way FD decode-and-forward (DF) relay is available for cooperative IRS/RIS FD systems [24], [25]. The papers [26], [27], [28], [30] addressing two-way FD primarily focus on the reciprocal channel which facilitates the received energy maximization for all users through the identical IRS phase shift design. For more complex scenarios involving spatial correlation [30], [31], multiple users [29], [30], [32] or non-reciprocity [32], research has typically focused on performance optimization algorithms than the derivation of performance expressions due to mathematical intractability of the latter.

The performance of ultra-dense cellular networks considering both adaptive discrete modulation (ADM) and energy harvesting (EH) is investigated. Particularly, mobile users (MUs) are charged its battery from all ambient radio frequency (RF) signals. Based on the amount of harvested energy as well as the channel conditions, MU will actively choose an appropriate modulation scheme that not only maximizes the rate but also satisfies the quality-of-service (QoS). Moreover, we consider the spatial-temporal correlation at the signal-to-interference-plusnoise ratios (SINRs) of base stations (BSs) which are totally different from work in the literature. Several important metrics are investigated such as, occurrence probabilities of different modulation schemes (Poc), coverage probability (Pcov), and achievable spectral efficiency (ASE). Finally, the results highlight the superiority of the proposed scheme compared to the conventional fixed modulation.

“…Non-orthogonal multiple access (NOMA) along with other advanced technologies such as deep learning [ 1 , 2 , 3 ], reconfigurable intelligent surfaces (RISs) [ 4 , 5 , 6 , 7 ], and tools from stochastic geometry (SG) [ 8 , 9 , 10 , 11 ] have been considered key-driven technologies for cellular networks beyond 5G, i.e., 5G-Advanced. More precisely, by allowing simultaneous transmit multiple signals within the same resource blocks (frequency and time) via different power levels and/or codes, NOMA can significantly enhance the spectral efficiency (SE) of the networks [ 12 , 13 ]. Additionally, NOMA can effortlessly combine with other techniques to further enhance system performance.…”

Outage probability (OP) and potential throughput (PT) of multihop full-duplex (FD) nonorthogonal multiple access (NOMA) systems are addressed in the present paper. More precisely, two metrics are derived in the closed-form expressions under the impact of both imperfect successive interference cancellation (SIC) and imperfect self-interference cancellation. Moreover, to model short transmission distance from the transmit and receive antennae at relays, the near-field path-loss is taken into consideration. Additionally, the impact of the total transmit power on the performance of these metrics is rigorously derived. Furthermore, the mathematical framework of the baseline systems is provided too. Computer-based simulations via the Monte Carlo method are given to verify the accuracy of the proposed framework, confirm our findings, and highlight the benefits of the proposed systems compared with the baseline one.
