However, because of the lack of flow information known in advance, such as when and what kind of flows will arrive and will be scheduled, it’s easy for most online routing and scheduling methods to reach the bottleneck of flow scheduling in the scenario where there are time-triggered flows with large period differences to be scheduled, resulting in a low scheduling success rate.In this paper, a flow preprocessing method is proposed to filter flows with certain characteristics that have potential negative influence on the overall scheduling success rate or bandwidth utilization according to their periods and arrival probability. The proposed method can be easily superimposed on any kind of online routing and scheduling methods in TSN to improve performance. The flow preprocessing method is evaluated in scenarios with different numbers and types of flows, and the result shows that the flow scheduling with our preprocessing method outperform the flow scheduling without preprocessing in terms of scheduling success rate, bandwidth utilization and computation time.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"10 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82069011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As known, OFDM has a very high peak-to-average power ratio (PAPR) which affects the system performance in presence of nonlinear power amplification. Many algorithms have been proposed to reduce the PAPR effect on the transmitted signal. The DVB-T2 and ATSC 3.0 standards adopted the technique of tone reservation (TR) which is based on an iterative process where a predefined kernel is applied to reduce a peak power at each iteration. In this paper, the Iterative Dichotomy PAPR reduction method (IDP) is used to reduce the PAPR of both DVB-T2 and ATSC 3.0 standards. The simulation results show that IDP-based PAPR reduction exhibits a gain of 2 dB, in terms of PAPR reduction, compared to TR.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"11 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79364408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current mobile communication networks only use external data service nodes, and the sensing of data is based on consumer subscription, which cannot meet the data service requirements of 6G networks. We propose a data service network architecture for mobile communication networks that supports intelligent collaboration of distributed data service nodes; transforms reactive subscription mode into proactive sensing mode with the assistance of AI/ML analysis; enhances data sensing, processing and storage mechanisms through the flexible use of data rules and knowledge, thus effectively improving the overall data service capability; further, with this architecture, possible solutions are discussed in detail with emphasis on data sensing difficulties.","PeriodicalId":13080,"journal":{"name":"IEEE international Symposium on Broadband Multimedia Systems and Broadcasting","volume":"27 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74298062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
