中國移動香港(00941.HK)成功創新研發首個5G頻譜池化網絡試點
阿思達克 06-13 16:29
中國移動香港(00941.HK)宣布,成功完成香港首個基於5G頻譜池化技術的5頻5G-A網絡試點部署,加速5G SA(獨立組網)網絡體驗升級,實現 「高效、智慧、綠色」 的網絡演進提供了全新模式。 中國移動表示,當前,現有網絡中存在大量的4G LTE、5G NSA(非獨立組網)、5G SA等各種模式終端,對於4G頻譜面向5G頻譜演進存在嚴峻挑戰,若採用逐頻重耕方式,4G及5G NSA用戶的高峰速率大幅下滑;若採用傳統的DSS(動態頻譜共用)技術,對不同頻段之間缺乏有效協同,導致系統性能未能達到最理想狀態。 針對這些問題,結合3GPP R19協議演進趨勢,CMHK聯合華為(Huawei)首次創新完成頻譜資源池化(GigaBand)網絡試點,成功將Sub3GHz碎片化的頻譜組成一個大帶寬的頻譜,形成一個彈性資源池,把傳統的載波聚合CA技術做成一個大帶寬的超級小區,5G SA網絡由3頻增加至5頻,最大帶寬從180MHz提升至240MHz,實現頻譜資源的歸一化共用和AI智慧化資源調度,提升5G SA網絡感知及頻譜效率。 中國移動指,在人口密集區域的測試結果顯示,頻譜池化後網絡性能顯著提升,4G和5G NSA用戶體驗保持平穩,而當場景缺乏3.5 GHz 及4.9 GHz覆蓋,5G SA用戶體驗可提升2.28倍#。此外,5G SA相較傳統的5G NSA手機終端具備更節能、時延更低、安全機制更強等優點。未來,CMHK將持續加速5G頻譜升級,為客戶帶來更優質、穩定、高效、節能環保的網絡連接體驗,推動數位化轉型,促進智慧生活的發展。
