隨著行動網路使用者愈來愈多以及更快速的需求，第三代合作夥伴計劃提出了長期演進技術以符合訊務量及傳輸率的需要，此技術中所使用的毫微微基地台更是不可或缺的角色。由於毫微微基地台總耗電量低，且具備隨插即用的方便性，毫微微基地台將可被大規模的佈建，在此環境下，則會面臨減少不必要的耗能且仍舊能維持良好的訊號與干擾雜訊比之挑戰。因此，本篇論文提出睡眠機制的設計，改善上述問題，透過模擬的方式可顯示所設計之機制能讓更多數量的毫微微基地台進入睡眠模式，進而節能，除此之外，訊號與干擾雜訊比不但沒有降低，反而可獲得提升的效果。

With more and more users and the demand for the high-speed transmission, the 3rd Generation Partnership Project (3GPP) releases the Long Term Evolution Advanced (LTE-A) to achieve this. In LTE-A, the indoor signal will be strengthened by deployment of femto eNodeBs. Due to its feature of low cost and plug-and-play, a femto eNodeB plays an important role. Therefore, femto eNodeBs will be deployed greatly in the future. In such a scenario, reduction of unnecessary power consumption is expected while the signal to interference plus noise ratio can be maintained. To achieve this goal, a power saving mechanism is proposed in this paper. Via simulations, we successfully show that our proposed mechanism can not only meet better signal to interference plus noise ratio but also gain more power saving because more sleep-mode femto eNodeBs are allowed.
