摘要:

针对D2D(device-to-device)通信复用蜂窝资源所带来的干扰问题,提出了一种单小区蜂窝系统下D2D通信的干扰控制和资源分配算法。首先,根据系统内用户之间的干扰构建干扰图,为 D2D 用户寻找可以复用的信道资源;然后根据预先设定的D2D用户优先级依次为D2D用户执行信道资源预分配和信道交换策略。仿真结果表明,所提出的算法可以明显提高系统的吞吐量以及D2D用户的接入率,使系统在存有少量或大量D2D用户的情况下都能使性能达到更优。

关键词: D2D通信, 干扰控制, 资源分配, 信道交换

Abstract:

In order to solve the problem of interference caused by D2D users reuse cellular resources in cellular network,an algorithm of interference control and resource allocation of D2D communication in single cell cellular system was proposed.Firstly,an interference graph was constructed according to the interference between users in the system to find the reusable channel resource for D2D users.Then,the channel resource pre-allocation and the channel switching policy were performed for D2D users in sequence according to the preset D2D user priority.The simulation results show that the proposed algorithm can significantly improve the system throughput and the access rate of D2D users so that the system can achieve better performance in the presence of small or large number of D2D users.

Key words: D2D communication, interference control, resource allocation, channel exchange
