摘要: 基于K层中继协作异构网络,提出一种改进的用户对关联方案,使中继广播信号到每层网络的信源和信宿,信源和信宿通过估计接收信号强度(RSS)将用户对关联到最大RSS的中继。基于最大-最大用户对关联(MM-UP-A)准则,结合随机几何理论将每层网络中继的位置建模为齐次泊松点过程,得到任一用户对关联到第k层中继的概率解析式,并给出信源和信宿到关联中继距离的统计描述。数值分析和仿真结果验证了MM-UP-A准则的正确性,并表明关联概率同时受到信源与中继发送功率的影响。

Abstract: Based on K-tier relay cooperative Heterogeneous Networks(HetNets),an improved user-pair association scheme is proposed,where relays broadcast its associated signals to source and destination of each tier,then source and destination associate the user pair to relay with the maximum of Received Signals Strength(RSS) by estimating the RSS.Based on the Max-max User-pair Association(MM-UP-A) criterion,by using stochastic geometry where the positions of relays in each tier are modeled as homogeneous Poisson point process,it gets the analytical expression of the probability that a typical user-pair is associated with a relay of the k-th tier as well as the corresponding statistical description of the distances from the source and destination of a typical user-pair to its serving relay.Numerical analysis and simulation results validate the correctness of the MM-UP-A criterion and show that association probability depends on the source and relay transmit power simultaneously.

Key words: fifth generation mobile communication, Heterogeneous Networks(HetNets), user-pair association, relay, association probability
