窄頻物聯網是第三代合作夥伴計劃用於支援廣域物聯網應用的標準。本篇論文提出一窄頻隨機存取通道的資源配置優化方式,使用多通道時槽式阿羅哈系統分析模型演示不同情形下封包之”重複機制”與”重傳機制”的權衡,將該分析模型延伸至窄頻物聯網之分析,並基於由實體層獲得的結果進行窄頻隨機存取通道的資源配置。該優化方式可以藉由模擬結果得到驗證。
Narrowband internet of things (NB-IoT) is a 3rd generation partnership project (3GPP) standard aiming at supporting wide area Internet of Things (IoT) applications. This work presents a methodology to optimize the resource allocation for NPRACH. We utilize a simple S-ALOHA model to demonstrate the tradeoff between ‘repetition’ and ‘retransmission’ under different situations. The simple model is then extended to analyze the performance of NB-IoT NPRACH. Finally, we utilize the model to set the NPRACH resource configuration based on the results obtained from the physical layer. The optimization methodology is verified by computer simulations.
