Resource allocation and co-channel interference are the two major technical challenges in the implementation of device-to-device communication technology. We propose an innovative resource allocation strategy along with dynamic power control for D2D communication. The resource allocation problem is formulated as a single utility function for multiple D2D pairs and cellular users in underlaying cellular networks. The proposed strategy based on overlapping coalition formation game allows a D2D pair to reuse multiple resource blocks. It aims to maximize the system sum rate maintaining minimal adverse impact of the interference on the overall system performance. Numerical results obtained through computer simulation show that the proposed strategy significantly improves the system sum rate along with reduced power consumption.

基于联盟游戏的D2D通信中资源分配和发射功率控制策略

资源分配和同信道干扰是实现设备间通信技术的两个主要技术挑战。我们提出了一种创新的资源分配策略以及用于D2D通信的动态功率控制。资源分配问题被公式化为底层蜂窝网络中多个D2D对和蜂窝用户的单个效用函数。提出的基于重叠联盟形成博弈的策略允许D2D对重用多个资源块。它旨在最大程度地提高系统总速率，同时将干扰对整体系统性能的负面影响降至最低。通过计算机仿真得到的数值结果表明，该策略显着提高了系统求和率，并降低了功耗。
