摘要
Device-to-Device(D2D)通信是下一代(5G)移动网络的重要组成部分。根据D2D用户在不同通信方式中的信道质量差异,以最大化系统吞吐量为目标,通过求解非线性模型,提出了两种资源分配算法。其中最优资源算法能够得到理论上的全局最优解,而次优资源分配算法作为前者的补充,可以在系统结构过于复杂时,为减少成本,提高效率而使用。实验表明,两种分配算法的性能十分接近,且远远高于随机分配算法。
D2D（Device-to-Device） communication would be an important component in next generation （SG） mobile network. In light of the diverse channel quality in different communication modes by D2D users and aiming at maximizing system throughput, two kinds of resource allocation algorithms are proposed through INLP model. The optimal resource allocation algorithm could theoretically acquire the global optimal solution, while the sub-optimal resource allocation algorithm, as a supplement to the former, could be used in complex system structure to reduce the cost and improve efficiency. Experiment indicate that these two al- location algorithms are quite close in performance ,and far better than the random allocation algorithm.
