最近，毫米波（mmWave）技術已被用作下一代無線通信系統的傳輸方案。 由於特定的傳播特性，可以有效地實現並發傳輸以提高頻譜效率。 在本文中，並發傳輸是通過在共享相同頻譜資源的基於mmWave的蜂窩網絡上部署多個設備到設備（D2D）廣播組來實現的。 為了很好地管理產生的頻譜共享干擾，多領導者多跟隨者（MLMF）Stackelberg賽局用於表徵蜂窩用戶（CU）和D2D組之間的多對多頻譜共享。 具體來說，CU扮演領導者的角色，而D2D小組則被視為追隨者。 在這種情況下，通過提出的自適應Gale-Shapley（AGS）算法解決了多對多（即CU和D2D組）配對問題。 此外，最佳的頻譜共享價格和傳輸功率被設計為最大化預定義的實用功能。 經復雜度分析和仿真結果驗證，該方案能夠以較低的信號開銷和計算複雜度很好地保持整體頻譜效率。關鍵字:毫米波，裝置間直接通訊，裝置間群播通訊，頻譜共享，線性天線陣列。

Recently, the milli-meter wave (mmWave) technology has been adopted as the transmission scheme for the next generation of wireless communication systems. Owing to specific propagation characteristic, the concurrent transmissions can be efficiently implemented to boost the spectrum efficiency. In this paper, the concurrent transmissions are fulfilled by deploying multiple device-to-device (D2D) broadcasting groups over the mmWave-based cellular network sharing the same spectrum resource. To well manage the incurred spectrum-sharing interference, the multi-leader-multi-follower (MLMF) Stackelberg game is utilized to characterize the many-to-many spectrum sharing between the cellular users (CUs) and D2D groups. Specifically, the CUs play the roles of leaders, while the D2D groups are treated as the followers. Under this scenario, the many-to-many (i.e., the CUs and D2D gorups) pairing problem is solved by the proposed adaptive Gale-Shapley (AGS) algorithm. Moreover, the optimal spectrum-sharing price and transmission power are designed to maximize the predefined utility functions. Verified by the complexity analysis and simulation results, the proposed scheme can well maintain the overall spectrum efficiency at the lower cost of signal overheads and computational complexity.
