摘要 Abstract 

5G行動網路使用波束成形技術來降低於高頻段傳輸之路徑損耗，在此演講中，我們探討5G多基地台網路下的波束排程且同時考慮使用者裝置節能之方案。此外我們亦考慮使用者裝置裝配有雙連接之功能並討論下行資料排程問題。

The 5G mobile network uses beamforming technology to resolve path loss when working in high-frequency band. We discuss the beam scheduling in the 5G multi-cell network and consider the energy saving of user equipments (UEs). In addition, we also consider UEs have dual connectivity capability and discuss related scheduling issues.
