摘要

摘要：针对macro-femto同频融合网络中基于资源分配的干扰抑制问题，提出一种联合子信道和功率分配算法来抑制同频干扰。该算法通过对MU进行功率控制并采用跨层切换消除同频跨层干扰，对FU进行联合信道和功率分配消除同频层内干扰；跨层切换问题是在每一层网络目标中断概率约束下通过优化网络吞吐量实现，而基于联合信道和功率分配的同频干扰抑制问题是在切换MU的目标数据速率和其他MU以及FU干扰门限约束下，通过优化FU的和速率实现。理论分析和仿真结果表明，该算法能够提高FU的和速率，增大femtocell的网络容量，并可增加femtocell的部署数目。

Abstract

A joint sub-channel and power allocation algorithm was proposed to suppress co-channel interference. Power control and handover mechanism could be used to suppress the co-channel cross-tier and intra-tier interference achieved by the power allocation for MU and joint sub-channel and power allocation for FU. Mathematically

the cross-tier handover was formulated as optimizing the network throughput under the constraints of each tier target outage probability and the interference-aware resource allocation was formulated as optimizing the sum rate of FU subject to the constraints of the target data rate of handover MU and interference thresholds to other MU and FU. Theoretical analysis and simulation results show that the sum rate of FU can be increased greatly. Meanwhile

the femtocell network capacity and the number of deployable femtocells can also be improved.
