技術說明

【中文】本發明揭露一種使用可重構智能表面(RIS)之全雙工通訊系統及方法，係由上行用戶裝置透過具有反射單元之可重構智能表面通訊連結全雙工基地台以建立上行鏈路之通道，且由全雙工基地台透過可重構智能表面通訊連結下行用戶裝置以建立下行鏈路之通道。繼之，全雙工基地台之可重構智能表面控制模組調整可重構智能表面之反射單元之相位，且由全雙工基地台之可重構智能表面優化模組依據上行鏈路與下行鏈路之通道計算出反射單元之相位之最佳封閉解以優化上行鏈路與下行鏈路，俾由可重構智能表面控制模組與可重構智能表面優化模組交互優化上行鏈路與下行鏈路之效能。【英文】 The invention discloses a full-duplex communication system and method using reconfigurable intelligent surface (RIS). A uplink user equipment communicates with a full-duplex base station through a reconfigurable intelligent surface having a reflective unit to establish a uplink channel, and the full-duplex base station communicates with a downlink user equipment through the reconfigurable intelligent surface to establish a downlink channel. Next, the reconfigurable intelligent surface control module of the full duplex base station adjusts a phase of the reflective unit of the reconfigurable intelligent surface, the reconfigurable intelligent surface optimization module of the full-duplex base station calculates an optimal closed solution of the phase of the reflection unit according to the uplink channel and the downlink channel to optimize the uplink and the downlink, so as to optimize performance of the uplink and the downlink by interaction between the reconfigurable intelligent surface control module and the reconfigurable intelligent surface optimization module.
