在现代通信系统中，服务速率和能耗越来越受到关注。为了支持高速本地服务，设备到设备（D2D）通信被引入蜂窝网络。然而，D2D带来的同频干扰和功耗带来了新的挑战。在本文中，我们专注于D2D集群场景中的能量有效的功率分配。基于凸优化中的对偶方法，本文提出了一种实用的D2D集群环境下的联合资源分配和功率控制（JRAPC）方案，即在保证服务质量（QoS）要求的前提下，为每个D2D用户在每个信道上分配合适的功率。仿真结果表明，该方案可以优化能量效率，降低调度复杂度，并导致更高的QoS满意度。
In modern communication systems, service rate and energy consumption have achieved increasing attention. To support high-speed local services, Device-to-Device (D2D) communication is introduced to cellular networks. However, the co-channel interference and power consumption brought by D2D bring new challenges. In this paper, we focus on energy-efficient power allocation in D2D-cluster scenario. Based on the dual method in convex optimization, we propose a practical Joint Resource Allocation and Power Control (JRAPC) scheme in D2D- cluster scenario, which is to allocate proper power for each D2D user on each channel and guarantee the Quality of Service (QoS) requirements. Numerical results show that the proposed JRAPC scheme can optimize the energy efficiency, lower the scheduling complexity and lead to higher QoS satisfactory.
