摘要

摘要: 针对D2D通信(device-to-device communication)与传统蜂窝通信共存下的能效资源复用问题,联合考虑蜂窝用户和D2D用户对的QoS约束,结合电路消耗功率,提出一种基于能效的D2D用户对与蜂窝用户最优匹配的资源复用和功率分配策略,分析了D2D用户对复用蜂窝用户资源的最优功率的存在性,并用分式规划理论求解了该最优功率的闭合表达式.仿真结果表明,相比已有算法,所提的能效资源复用策略的D2D用户的总能效最优,并且该总能效在低QoS要求下相比最大化和速率算法提高36.25%,高QoS要求下略高于基于节能的功率分配算法,同时还具有1.7~3 Mbit/s的和速率.

Abstract: Energy efficiency is an important problem in mobile communication. Resource reuse and power allocation strategy based on energy efficiency was proposed for energy efficiency resource reuse of D2D (device-to-device) communication coexisting with traditional cellular communication, in which the QoS (quality of service) requirements of D2D pairs and cellular users and circuit consumption power were taken into account. The existence of the optimal power allocation of the D2D pairs was analyzed, and the closed expression of the optimal power was also obtained using fractional programming theory. Simulation results show that, compared to the existing schemes, the proposed scheme achieves the best energy efficiency while guaranteeing the sum-rate of 1.7 Mbit/s to 3 Mbit/s, and energy efficient of the proposed scheme is improved 36.25% compared to the maximum sum-rate algorithm when the requirements of QoS are low and slightly higher than the energy-saving based power allocation algorithm when the requirements of QoS are high.
