上一筆

　　由於HeNB可由室內公共場所等進行安裝，不像eNB是經過網路歸劃過後架設，因此造成了不協調式的HeNB建置狀況，導致產生基地台彼此或與使用者設備等之間訊號干擾，致使降低載波的利用率及傳輸速度，尤其位於封閉型用戶群組(Closed Subscriber Group；CSG)環境下甚是。
　　為了要解決上述問題，本論文提出LTE-Advanced藉由載波聚合(Carrier Aggregation；CA)技術於HeNB不協調式建置環境干擾之下，利用載波自主重新分配選擇(Autonomous Component Carrier Selection；ACCS)技術，且依主載波(Primary Component Carrier；PCC)與次載波(Secondary Component Carriers；SCCs)的特性不同，提出載波選擇及重新分配方法，我們將所提出的方法與標準載波分配方式做比較，從模擬結果可知，在各項效能評估項目上，本論文提出的載波自主重新分配選擇技術會有更好的公平性、載波利用率及網路系統產能。

　　Since HeNB can be set up in every family, the department stores or any indoor public places; HeNB is different from eNB which is set up through network planning; thus it causes the uncoordinated HeNB provisioned status to interfere the signals between the cell base station and the user equipment, that results in reducing the utilization of the carrier and the transmission speed, especially in the Closed Subscriber Group (CSG) environment.
　　In order to solve the above problems, this thesis points out under the interference caused by the uncoordinated HeNB provisioned status, LTE-Advanced with Carrier Aggregation (CA) technology can use “Autonomous Component Carrier Selection” (ACCS) technology that could be capable to find out the carrier transmission link in a noisy, poor environment and request to release the carrier allocation again to achieve the better data transfer speed. We compare the proposed method with the standard carrier allocation method: From the simulation results based on the evaluation in every performance, the technology: ”Autonomous Component Carrier Selection” in this thesis will provide a better fairness utilization of the carrier and network capacity.
