Abstract:

Based on the conflict graph model which is formulated as a binary integer optimization problem, a resource allocation method to support device-to-device(D2D)communications in cellular networks is proposed. First, a frequency resource assignment algorithm is presented which assigns each D2D link one frequency resource block. For this algorithm, frequency resource blocks are assigned so that the frequency resource spatial reuse opportunities in the cellular networks can be fully exploited. Then a slot scheduling algorithm is presented which schedules time slots among D2D links assigned the same frequency resource block. For this algorithm, time slot resources are scheduled so that the proportional fairness among D2D links which are assigned the same frequency resource block can be achieved. The performance of the proposed method is evaluated via computer simulations. The simulation results show that the proposed method can well support D2D communications in cellular networks.

基于冲突图模型形成的二进制整数规划, 提出了一种蜂窝网络中支持D2D通信的无线资源分配方法.首先, 提出一种频率资源分配算法, 即为每个D2D链路都分配一个频率资源块.分配频率资源时将尽可能地利用蜂窝网络中的无线频率资源空间重用机会.然后, 提出一种时隙调度算法, 即为所有分配同一频率资源块的D2D链路进行时隙资源调度.调度时隙资源时将保证使用同一频率资源块的D2D链路之间达到长期平均吞吐率的比例公平.通过计算机仿真对所提出方法的性能进行了验证, 结果表明该方法能够在蜂窝网络中实现D2D通信功能.
