我们考虑一组设备到设备 (D2D) 链路和多个共置蜂窝网络之间的频谱共享问题。每个蜂窝网络都由一个运营商控制，该运营商可以为多个用户提供服务。每个D2D链路可以访问蜂窝用户占用的子带，或者获得一个空子带供其专用。我们为蜂窝网络中的 D2D 通信引入了一种新的频谱共享模式，允许两个或多个独占子带的 D2D 链路彼此共享子带，而无需咨询运营商。我们建立了一种新的博弈论模型，称为贝叶斯不可转让效用重叠联盟形成（BOCF）博弈。我们证明我们提出的游戏可以用来建模和分析上述频谱共享问题。然而，我们观察到 BOCF 博弈的核心可以是空的，并且我们推导出核心非空的充分条件。我们提出了一种分层匹配算法，可以检测是否满足充分条件，如果满足，则实现稳定且唯一的匹配结构，该结构与 BOCF 博弈核心中的重叠联盟协议配置文件一致。
We consider the spectrum sharing problem between a set of device-to-device (D2D) links and multiple co-located cellular networks. Each cellular network is controlled by an operator which can provide service to a number of subscribers. Each D2D link can either access a sub-band occupied by a cellular subscriber or obtain an empty sub-band for its exclusive use. We introduce a new spectrum sharing mode for D2D communications in cellular networks by allowing two or more D2D links with exclusive use of sub-bands to share their sub-bands with each other without consulting the operators. We establish a new game theoretic model called Bayesian non-transferable utility overlapping coalition formation (BOCF) game. We show that our proposed game can be used to model and analyze the above spectrum sharing problem. However, we observe that the core of the BOCF game can be empty, and we derive a sufficient condition for which the core is non-empty. We propose a hierarchical matching algorithm which can detect whether the sufficient condition is satisfied and, if it is satisfied, achieve a stable and unique matching structure which coincides with the overlapping coalition agreement profile in the core of the BOCF game.
