研究了基于非正交多址(NOMA)的能量采集蜂窝网络中设备到设备(D2D)通信中的资源分配问题，其中能量采集供电的D2D通信共享蜂窝网络的下行链路资源。为了充分利用该系统中的高数据速率D2D链路，提出了一种面向D2D用户的两阶段架构。具体地，D2D用户在第一阶段从基站(BS)获取能量，然后在第二阶段使用所获取的能量发送他们自己的信息。同时，D2D通信可能会对蜂窝用户(CU)造成严重干扰，从而可能破坏CU的SIC解码顺序。针对这一问题，提出了联合功率分配和时间调度方案，在保证每个CU的服务质量的同时最大化D2D链路的吞吐量。通过严格的推导，分析了最优功率控制和时间调度参数，简化了优化问题的描述。在某些情况下，得到了闭合形式的最优解。在其他情况下，使用基于梯度的算法来寻找适当的次优解。仿真结果验证了该方案比传统的正交多址(OMA)方案的优越性。
This paper investigates the resource allocation problem in device-to-device (D2D) communications underlaying a non-orthogonal multiple access (NOMA)-based cellular network with energy harvesting, where the energy harvesting-powered D2D communications share the downlink resources of the cellular network. To fully exploit the high-data-rate D2D links in this system, a two-phase framework is proposed for D2D users. In particular, the D2D users harvest energy from the base station (BS) in the first phase and then transmit their own information using the harvested energy in the second one. Meanwhile, the D2D communications could cause severe interference to cellular users (CUs) and hence probably ruin the SIC decoding order of the CUs. To deal with this issue, joint power allocation and time scheduling scheme is proposed to maximize the throughput of the D2D links while guaranteeing the quality of service (QoS) for each CU. Through rigorous derivation, the optimal power control and time scheduling parameters are analyzed to simplify the optimization problem formulation. The closed-form optimal solution is derived in some cases. In other cases, a gradient-based algorithm is employed to find an appropriate sub-optimal solution. The simulation results are demonstrated to validate the superiority of the proposed scheme over the conventional orthogonal multiple access (OMA) scheme.
