| 摘 要： | 针对具有自组织特性的家庭基站(home eNodeB, HeNB) 网络，提出了一种分布式资源分配算法. 该方法首先使HeNB 根据网络状况选择分量载波，而当接收到邻小区的重选请求时，可以重新选择备用载波列表中的载波，释放当前使用的载波给邻居使用，从而提高HeNB 获得可行载波的可能性. 使HeNB 根据优化目标函数自主地进行功率优化，以减少小区间干扰并提高系统容量. 通过蒙特卡罗方法分析该算法的性能，仿真结果表明：该资源分配算法能够提高用户的平均吞吐量并降低中断概率. |

| Abstract: | A distributed algorithm is proposed for resource allocation in self-organized home eNodeB (HeNB)networks. In this algorithm, each HeNB selects component carriers (CC) based on the network status. If a reselection request is received from neighboring cells, the HeNB will reselect the CC in the backup CC list, and release the CC requested by neighbors to enhance possibility of successful carrier selection. Each HeNB then adaptively performs power optimization in active CCs to reduce inter-cell interference and enhance the system capacity. Simulation results show that this resource and power allocation algorithm can enhance average user throughput and reduce the outage rate. |
| Keywords: | home eNodeB (HeNB) backup component carriers (CC) list carrier reselection inter-cell interference power optimization |
