長期演進技術升級版(Long Term Evolution Advanced, LTE-A),是基於長期演進技術(LTE) 的升級版,額外增加了許多新的技術,其中一項技術為中繼站(Relay)。中繼站能有效的改善位於服務範圍邊緣使用者的服務品質,還能延伸服務範圍。然而,中繼站的加入也造成一些影響,例如中繼站傳輸功率會對其他不同基地台中的中繼站造成影響。本篇論文提出新的動態中繼器功率分配(Dynamic Relay Power Allocation, DRPA) 機制來解決該問題。DRPA 會依據各個資源區塊(Resource Block, RB) 所使用的通道品質指標以及該中繼站所配置到的資源區塊數,來做調整中繼站的傳輸功率,降低對其他節點的影響,改善通道品質、提升通道容量、維持吞吐量,藉以達到節能的目的。
The Long Term Evolution Advanced (LTE-A) is an enhanced standard based on the Long Term Evolution (LTE) by adding some new technologies, e.g., relay stations etc. A relay station can not only effectively improve the service quality of the user equipments (UEs) located near the edge of service coverage but also extend the service coverage. However, some side effects of relay stations have been raised, for example, the impact caused by the transmit power of relay stations to the other relay stations. To properly address such an issue, a dynamic relay power allocation (DRPA) mechanism is proposed in this thesis. According to the Channel Quality Indicator (CQI) and the number of Resource Blocks (RBs) allocated to the relay station, DRPA will adjust the relay transmit power to alleviate the interference from the other nodes to improve the channel quality, enhance the channel capacity, and maintain the throughput while achieving the purpose of power saving.
