  2. 目錄 • INTRODUCTION • SHORT TERM EVOLUTION OF LTE • NETWORK ARCHITECTURE BEYOND 4G • D2D • Wi-Fi Direct • CONCLUSION

  3. 一、INTRODUCTION

  4. 二、SHORT TERM EVOLUTION OF LTE • Small cell enhancement • LTE-WiFi integration • 3D Beamforming and Massive MIMO • Interference Management and Traffic Adaptation • Machine Type Communication

  5. 三、NETWORK ARCHITECTURE BEYOND 4G • 未來的移動通信網絡: • 超密集。 • 不同的技術融合。 • 網路基礎設施輔以D2D。

  6. 四、D2D

  7. 鄰近裝置搜尋問題： 基地台在收到裝置搜尋的請求 基地台或後端網路主動參與協尋過程 連線干擾： D2D 裝置與傳統裝置之干擾：那些傳統裝置與D2D裝置可共享資源 D2D 裝置和基地台間之干擾：限制D2D裝置 D2D 裝置間之干擾：允許多組D2D裝置同時共享資源

  8. 五、Wi-Fi Direct

  9. 六、CONCLUSION 未來的移動通信網絡將以不同的接入技術融合D2D。 超密集的無線電網路具有許多不同大小的細胞，增加系統容量的最有效的方法和覆蓋服務區。 不同的接入技術融合，確保授權和未授權頻譜都沒有用戶的認知無線高效地集成在一起。 D2D可以緩解核心網絡擁塞或補充傳統的基礎設施網絡中的場景。 創造豐富創新和半導體行業的商業機會。

  10. 參考文獻 • GM測試採用Wi-Fi Direct技術的人形偵測系統 • 裝置對裝置 (D2D) 通訊之應用與挑戰
