设备到设备（D2D）通信作为蜂窝网络的一种扩展，为用户的吞吐量和电池寿命带来了显著的益处。向D2D通信分配功率和信道资源需要精细的协调，因为D2D用户设备（UE）对其他UE造成干扰。本文提出了一种新的资源分配方案来提高D2D通信的性能。电池寿命被明确视为我们的优化目标。我们首先将分配问题公式化为非合作资源分配游戏，其中D2D UE被视为竞争信道资源的玩家。然后，我们加入价格的游戏，以提高效率，并提出了一个有效的拍卖算法。我们还进行了模拟，以证明所提出的算法的有效性。
Device-to-device (D2D) communication as an underlay to cellular networks brings significant benefits to users' throughput and battery lifetime. The allocation of power and channel resources to D2D communication needs elaborate coordination, as D2D user equipments (UEs) cause interference to other UEs. In this paper, we propose a novel resource allocation scheme to improve the performance of D2D communication. Battery lifetime is explicitly considered as our optimization goal. We first formulate the allocation problem as a non-cooperative resource allocation game in which D2D UEs are viewed as players competing for channel resources. Then, we add pricing to the game in order to improve the efficacy, and propose an efficient auction algorithm. We also perform simulations to prove efficacy of the proposed algorithm.
