| dc.description.abstract | 隨著5G頻寬日益稀缺，尋找額外頻寬或提高使用效率已成為關鍵課題。為了應對這一挑戰，相關標準組織提出了新型無授權頻段（NR-U）來擴展5G頻寬，並引入多播與廣播服務（MBS）以提升頻寬利用效率。本文首次提出將NR-U與MBS結合的方案，並提供一套分析模型進行驗證。透過精密設計結合這兩個元素，我們的最佳解法在20個無線網路接取點的環境中，效能相較於現有技術提升達7.27倍。此外，我們的方法完全符合標準規範，效能也提升至現有技術的3.92倍。我們根據站點間距與頻率等參數進行多項模擬，並得出多項具有啟發性的結果。 | zh_TW |
| dc.description.abstract | With the increasing scarcity of 5G bandwidth, finding additional bandwidth or improving usage efficiency has become critical. The 3GPP proposed the New Radio Unlicensed (NR-U) band to expand 5G bandwidth and introduced Multicast and Broadcast Service (MBS) to enhance bandwidth utilization efficiency. This paper is the first to propose the integration of NR-U and MBS, along with an analytical model for validation. Through a sophisticated design combining these two elements, our optimal solution outperforms the state-of-the-art (SOTA) by a factor of 7.27 in an environment with 20 Wi-Fi APs. Furthermore, our fully 3GPP standard-compliant method achieves 3.92 times the performance of the SOTA. We conducted various simulations based on parameters such as inter-site distance (ISD) and frequency, deriving several insightful results. | en |
