To assess performance and fairness, we compare the traditional ML–WH pair with the proposed ZC–WH and ZC–ML pairs. While ZC-based combinations generally offer improved performance, our findings indicate that the noncyclical nature of the WH sequence in the ZC–WH pair introduces performance degradation due to imperfect channel estimation in NOMA scenarios.

To address these challenges, this paper proposes a mobility-aware intelligent reflecting surface-assisted hybrid NOMA (M-IRS-HNOMA) framework for THz downlink transmission in 6G networks. The proposed design integrates three components: (i) IRS-enhanced THz propagation to mitigate severe path loss and extend coverage, (ii) a mobility and quality-of-service (QoS) aware hybrid clustering strategy that applies NOMA within clusters and OMA across clusters to balance spectral efficiency and SIC complexity, and (iii) a deep reinforcement learning (DRL) model that jointly optimizes power allocation, IRS phase shifts and hybrid access parameters under time-varying channels. A unified optimization problem is formulated to maximize the weighted sum-rate subject to power, QoS, and IRS hardware constraints and is decomposed into tractable power and phase-shift subproblems embedded within the DRL control loop for real-time adaptation. Simulation results demonstrate that, compared with conventional HNOMA, IRS-OMA, cooperative NOMA, and static IRS-NOMA baselines, the proposed M-IRS-HNOMA achieves significantly higher spectral efficiency, improved energy efficiency and reduced end-to-end latency in THz mobility scenarios, confirming its potential as a practical solution for ultra-dense 6G communications.</p>\u0000 </div>","PeriodicalId":13946,"journal":{"name":"International Journal of Communication Systems","volume":"39 8","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These developments allow exceptionally high spectral efficiency and provide communications that are remarkably reliable. Methods that are traditionally used to cut down peak-to-average power ratio (PAPR) are excessive clipping, selective mapping, and tone reservation. All of which, in one way or another, are incapable of pragmatic use due to the distortion of the signal, considerable complexity, and the requirement of additional information. In light of these limitations, this research introduces the heterogeneous edge-enhanced circular dilated convolutional graph attention network (Het-ECDCGAN)–based PAPR reduction framework. It draws on techniques from circular dilated convolutional neural networks (CD-CNNs) and heterogeneous edge-enhanced graph attention networks (HE-GATs). The CD-CNN successfully separates long-range information from periodic peak structures in the time–domain, while the HE-GAT utilizes graph-based attention techniques to model inter-subcarrier and inter-antenna correlations. Binary Portia spider optimization is applied to optimize the performance of Het-ECDCGAN. The designed framework can reach a bit error rate (BER) of up to 10<sup>−4</sup>, which guarantees good transmission and efficient PAPR reduction. In line with the validation of resilience at varying spectral efficiencies, modulation schemes, which include QPSK, 16-QAM, and 64-QAM schemes, are tested.

These problems can be addressed by proposing the advantages of nonorthogonal multiple access (NOMA)–based cooperative green cognitive radio networks (GCRNs) utilizing green secondary users (GSUs) as relays. For this, an auction market is designed with the composition of BS (auctioneer), GSUs (sellers), and PUs (buyers). The PUs must pay for the cooperative service provided by GSUs, while GSUs sell it for revenue. Moreover, PUs can adjust their bid according to their residual energy. Thus, less energy PUs have a higher chance of winning GSUs' service to prevent energy exhaustion. Meanwhile, GSUs reduce their ask price as per the amount of energy harvesting (EH). Hence, GSUs can serve more PUs if they harvest more energy from the received NOMA signal. Three auction rules impacting GSUs (as relay) selection are also being proposed. Finally, the simulation illustrates the diverse performance of three auction rules (with their merits and demerits) in selecting GSUs.
