近幾年來隨著無線網路的蓬勃發展，手持行動裝置(Cellular User Equipment; CUE)的資料量更是呈現爆炸性的成長，為了因應這個現象， 裝置對裝置(Device-to-Device; D2D)通訊是第五代行動網路(5th generation network; 5G network)中一個相當關鍵的技術，然而，由於頻譜的稀缺性， 大量的裝置需求也帶來了一系列的挑戰，頻譜共享(Spectrum Sharing)的 概念也開始受到廣泛地討論，頻譜共享技術允許多個裝置在同一個頻譜資 源上運行，因此被視為在 5G 網路中相當重要的技術.儘管此技術能夠增 加系統的頻譜效益(Spectral Efficiency; SE)，但也因此限制了裝置間通訊 的品質.
本論文主要討論在頻譜共享 D2D 通訊頻譜共享的行動網路(Underlay cellular network)中，藉由 D2D 共用行動網路的頻譜而提升頻譜效益，但 此時干擾源的增加也大大地影響通訊的品質，本論文將此資源分配問題比 擬成非合作性的賽局，藉由賽局理論有效地分配 D2D 共用行動網路的頻 譜而最大化頻譜效益，同時必須確保各個裝置通訊中受到較低的干擾.由 模擬結果可以得知此方法可以在各種 UE 分佈的情況下有效地動態分配 通道給不同的 D2D 使用，同時保證各裝置通訊間的品質及提升頻譜效益.

With the thriving development of wireless technology, people have already witnessed the massive growth of cellular user equipment (UE). Device-to-Device (D2D) communication is one of the promising paradigms in the fifth generation (5G) network. The current spectrum of the existing cellular networks cannot meet the demand of massive devices, especially with the emerging Internet of Things (IoT) applications. Thus, the spectrum deficiency issue has drawn a lot of attention all over the world. To deal with this challenge, the spectrum sharing technique started to show off. The spectrum sharing technique allows multiple devices to utilize the same frequency resource of cellular networks. It can be regarded as one of the key techniques in 5G technology. Even though it can leverage spectral efficiency (SE), it also downsizes the quality of service (QoS) of devices. The interference can lead to huge concerns if the number of devices increases. Therefore, one of the biggest challenges of spectrum sharing is interference management.
This thesis is dedicated to studying D2D communication on cellular network, which is also called D2D underlay network. In the underlay network, D2D pairs can utilize the frequency resources of cellular users to communicate. This behavior is expected to increase system spectrum efficiency. However, not every D2D pair can utilize the frequency resources of cellular users because the caused interference may influence both in-use cellular users and other D2D pairs. This thesis modelled this resource allocation problem as a non-cooperative game. Using the game theory to allocate the frequency resource of D2D pairs on cellular network effectively and maximize the spectral efficiency while ensuring the quality of every communication maintains at a certain level. The simulation results show the proposed scheme can improve the spectral efficiency significantly and ensure the received interference of every communication is low. The approach can be operated individually. Therefore, it is suitable for the implementation of real scenario because it does not cause too much burden to the BS.
