针对异构网络融合环境提出一种基于中继节点辅助的毫微微蜂窝(Femtocell)混合接入控制算法,为Femtocell网络相邻用户(NUE,neighboring user)提供较好的性能支持。该算法将中继节点部署在网络外围的架构,通过中继放大转发或直传链路的传播方式对 NUE 进行数据传输,并设置 Femtocell 网络注册用户(FUE, Femtocell user)的QoS门限值、宏蜂窝用户(MUE,Macrocell user)的跨层同频干扰容忍门限值以及Femtocell基站(FBS,Femtocell base station)下行总功率受限为约束,将上述资源分配问题建模成最优化问题,通过采用对偶分解算法进行求解,并将直传与中继放大转发模式相结合,从而适用于多用户多基站环境下 Femtocell 混合接入。仿真结果显示,所提算法不仅能够对FUE的QoS进行保护,还能有效降低对MUE的跨层同频干扰,而且动态、灵活地改变NUE的接入模式,较大幅度地提高NUE的系统性能,且在一定区域内采用中继转发链路获得的数据传输速率要比采用传统直传链路的数据速率高约25%左右。
A Femtocell hybrid access control algorithm assisted with relay note was proposed to supply higher performance for the Femtocell neighboring users (NUE) in heterogeneous network.Deploying relay outside the Femtocell networks was used and amplify-and-forward (AF) relaying protocol or direct link protocol was alternated to use for the data transmission of Femtocell NUE.An optimization problem was formulated with the constraints of the required transmission rates thresholds of Femtocell registered users (FUE)
the thresholds of the cross-tier interferences to the macrocell users (MUE)
and total transmit powers of the Femtocell base station (FBS).By using the dual decomposition method
a Femtocell hybrid access control algorithm was given based on the combination of the direct mode and relay mode.Simulation results have shown that the scheme can not only protect the QoS required by the FUE
but also decrease the cross-tier interferences suffered by the MUE.It also illustrates the better performance of the NUE through the dynamic and flexible access mechanism.Furthermore
based on the last simulation the relay link would help the NUE obtain about 25% more performance than the traditional direct link in some regions.
