User pairing scheme in mobility-aware D2D communication system

摘要

In this study, a user pairing scheme in mobility-aware device-to-device (D2D) communication system is proposed. One D2D user equipment (DUE) pair consists of a D2D transmitting user equipment and a D2D receiving user equipment. First of all, the network model, communication time model and moving model are presented. Then the mathematical characteristics of the capacities of DUEs in different moving mode are analysed. Based on the analysis above, a user pairing scheme in mobility-aware D2D communication system is proposed. Finally, simulation results show the capacity performance of the proposed scheme outperforms that of the other algorithms. This result can be applied into the deployment and optimisation of D2D communication system.
