基于Kuhn-Munkres最优匹配的D2D资源分配算法设计

由于资源复用,D2D链路与蜂窝链路之间会产生同频干扰。为了抑制这种干扰,提出了一种基于Kuhn-Munkres最优匹配的资源分配算法。该算法采用了图论中的Kuhn-Munkres最优匹配算法来实现最大限度的复用系统内的RB,达到提高系统吞吐量的目的。同时,通过使一对D2D用户复用多个RB进行通信以保证不同的Qo S需求。最后,通过计算机仿真可以看出,该算法既可以有效地满足D2D用户的不同Qo S需求,又提高了系统吞吐量。...

There were interference between D2D links and cellular links due to resource reuse. In order to limit the interfe- rence effectively, this paper proposed a Kuhn-Munkres optimal matching based resource allocation scheme for D2D users. Adopting Kuhn-Munkres optimal matching could not only reuse RB as many as possible to improve system throughput, but also allocated sufficient RB for D2D users as needed to meet QoS requirements. Finally, the computer simulation shows that the scheme can fulfill D2D users QoS requirements effectively and improve the system throughput.
