4G MAC/PHY跨層控制信號流程與資源排程技術

4G MAC/PHY Cross Layer Control Signaling and Resource Scheduling

摘要


4G(LTE, WiMAX)通訊系統提供了更高的頻寬傳輸速率,在多用戶需求以及龐大的資料傳遞之下,控制信號傳遞與資源排程方式便是一個傳輸速率影響的重要依據。本論文提出新式排程技術演算法設計,藉由適應性的調整行動裝置(mobile station;MS)所回報的通道品質數據,來選擇適當的調變方式,藉此降低時序延遲效應以及改善傳輸錯誤率,並藉由系統級模擬驗證,整體用戶傳輸吞吐量(throughput)達到各家廠商制訂的標準。此外,本論文亦提出MAC與PHY跨層控制流程設計架構,此架構符合LTE通訊協定標準規範,亦能擴展至WiMAX通訊標準平台規格中,此流程控制設計可結合所提出的排程演算法技術, 使平台設計符合標準規範並使整體效能提升。

It provides higher transmission rate in the 4G (LTE, WiMAX) communication system. Cross layer control flow design and resource allocation algorithm are two important issues for improving the number of active users and providing higher data rate. In this paper, a new scheduling algorithm is also proposed in this paper. The adaptive modulation for data scheduling will be selected with respect to channel quality information (CQI) and modified back-off values. Verified by the system level simulation results, the proposed algorithm will meet the standard requirement. Besides, a new cross layer flow structure for MAC and PHY layer is proposed. It is not only available for LTE spec. requirement, but also extends to WiMAX communication standards. The flow structure could be integrated with the scheduling algorithm to achieve the standard requirement and improve the platform efficiency.
