在干扰受限的通信场景中，干扰会损害数据传输并进一步降低延迟性能。研究了具有干扰限制中继的无线双跳网络的随机时延保证问题。考虑到无线衰落在数据链路和干扰链路中的随机性，网络提供的随机服务过程的矩生成函数（MGF）。由于服务过程是随机的，因此延误应该是一个随机变量。延迟中断概率被定义为实际传输延迟超过阈值的概率。为了评估随机延迟保证，我们推导出一个上限的最小可接受的延迟阈值和下限的最大可支持的传输数据大小的延迟中断概率的约束，分别。仿真结果表明，理论分析得到的界是合理的紧，很好地反映了干扰对随机延迟保证的影响。
In the interference-limited communication scenarios, the interference impairs the data transmission and further degrades the delay performance. In this letter, the stochastic delay guarantee for a wireless dual-hop network with an interference-limited relay is investigated. Considering the randomness of wireless fading in both data links and interference links, the stochastic service process provided by the network is characterized in terms of the moment generation function (MGF). Due to the stochastic service process, the delay should be a random variable (RV). The delay-outage probability is defined as the probability that the actual transmission delay exceeds a threshold value. To evaluate the stochastic delay guarantee, we derive an upper bound on the minimum acceptable delay threshold and a lower bound on the maximum supportable transmitted data size with the constraint of the delay-outage probability, respectively. Simulation results show that the bounds obtained by the theoretical analysis are reasonably tight and well reflect the effect of the interference on the stochastic delay guarantee.
