隨著軟硬體技術的提升，使用者對於無線傳輸速率的要求日益提升，Massive MIMO是次世代一重要的通訊技術，透過調整天線的使用數量，盡可能提供使用者更好的服務。在本文中，我們提出一個Massive MIMO基地台無線後端網路中的資源分配方法。我們提出的方法可透過調整每個基地台的天線分配，在滿足每個基地台使用者的服務品質(QoS)後最佳化整體效益。經由分析，我們證明此分配問題為NP-complete，而我們的方法與最佳解的差異也受到了局限。模擬結果顯示在各種情況下，本文提出方法皆能根據基地台的需求以及通道狀況來達到有效的資源分配，並得到近似於最佳解的效能。

With the improvement of hardware and software technology, users of the wireless transmission rate requirements are increasing, Massive MIMO is the next generation of an important communication technology, by adjusting the allocation of antennas, as far as possible to provide users with better service. In this paper, we propose a resource allocation method for a Massive MIMO base station wireless backhual network. Our approach can be achieved by adjusting the antenna allocation of each base station and optimizing the overall benefit after satisfying the quality of service(QoS) of the users in the system. By analysis, we prove that this distribution problem is NP-complete, and the difference between our method and the optimal solution is also limited. The simulation results show that in this case, the proposed method can achieve the effective resource allocation according to the requirements of the base station and the channel condition, and get the similarity to the optimal solution.
