隨著目前行動通訊網路的技術不斷的演進，不僅提供便利又快速的網路，同時也會需要考量到使用的能源對地球環境的影響，以及在使用者用戶增加需求量以及設備數量的情況下，要如何提高能源的效率以及綠能的使用將會在未來通訊技術領域中被重視。
本論文中提出一個針對小細胞網路下之聯合充電和資源的分配機制，設計出調整小細胞基地台的市電與綠能傳輸功率、資源塊的分配、訊息和無線充電的傳輸能量比之演算法來找到最佳化資源的分配，從而提升整體能源的效率。
在考慮的小細胞網路之環境下具有多個小細胞基地台，小細胞基地台可使用市電與綠色能源來供應給本身，並且在傳輸資料的同時為使用者用戶設備進行無線充電的服務。小細胞基地台透過下鏈(Downlink)讓使用者各別利用時槽接收能量與資料。然而，為了能夠使小細胞基地台能夠達到省電的效果，設計並使用了能源廣播以及能源相關廣播兩種方法，來找出使用者用戶之間所需最大的能量並獨立於時槽內並廣播充電給每一個使用者用戶。長久下來可以幫助小細胞基地台減少所需配送的能量，不僅提升了整體頻寬的使用率來讓效率提升，也幫助了小細胞基地台達到省電的效果。
從模擬實驗中可得知，透過加入了調整小細胞基地台與使用者用戶之間的頻寬，以及資料時槽的效益分配，可以得到更好的能源效率，讓使用者用戶設備的資料時槽效益提升，同時也幫助了小細胞基地台達到了省電的作用。

With the continuous evolution of mobile communication network technology, system not only provide a convenient and fast internet, but also needs to consider the impact of the energy used on the global environment. In the case of increasing user demand and quantity, how to improve energy efficiency and to use green energy will be valued in the future of communication technology.
This paper proposes a joint charging and resource allocation for small cell networks, and designs an algorithm to adjust the on-grid power, green power, resource block allocation, the transmission power ratio of information, and wireless charging of small cell base stations, to find the optimal allocation of resources, which improves overall energy efficiency.
Consider a small cell network environment with many small cell base stations where small cell base stations can use on-grid power and green power to supply themselves. While transmitting data, it provides wireless charging service for user equipment. The small cell base station allows users to use the time slot to receive energy and data through the downlink. However, in order to allow small cell base stations to achieve power savings, we design and use two methods of energy broadcasting and energy-related broadcasting, to find the maximum energy required between users and separate it from the time slot and broadcast charging to every user. In the long run, it can help small cell base stations to reduce the energy required for distribution. It not only improves the overall bandwidth utilization rate to increase efficiency, but also helps small cell base stations to achieve power saving effects.
From the simulation experiment, by adding the adjustment of the bandwidth between the small cell base station and the user, system can benefit distribution of data time slot, and get better energy efficiency, and improve the data time slot efficiency of user equipment. At the same time it also helped the small cell base station to achieve power saving.
